I'm not a mechanic; however, I started getting a lot of problems after taking my vechicle here for an oil change and what seem at the time as a battery problem. I have a 2008 328I so my vehicle isn't old by any means. At first I was very impressed by Pat's helfulness and customer service but the battery light was still on the same day I got my vehicle back. When I took my car back he said it was because of a bad valve. So I ended up getting that replaced. I have my suspicions on if i really needed to change my batery to begin with or did I spend over $300 for nothing. Be careful and take notes when he gives you a price because he would have charged me more if I didn't question his final bill. Well, it's been two months since i had my valve replaced and the car is having trouble starting. I took my car there in the morning and he set me up with a rental while he diagnosed the problem. He didn't pick up the phone when i tried to get an update and on the second day he wouldn't return or answer my calls. It was Friday so I didn't want to be stuck with rental car over the weekend. My boyfriend and I had to call him on three way because I suspect he was screening my calls, and to no surprise he picked up the phone right away. I believe he had no idea what the problem was at that time and that's why he didn't answer my calls. Instead of telling me he is still looking into it, he told me it was the ECU, which is the computer of the car. A new one would cost thousands of dollars but he could try to put a used one in for $400. This did not make any sense to me so I decided to call a BMW dealership for their opinion. THe gentleman said this hardly goes bad and doubt this was the problem. I called Pat and told him I didn't not want to proceed and asked what I should do with the rental. Since he was not repairing my car, he did not cover the rental. Mind you, it took him two days before i could get any kind of answer. I got stuck having to pay for the car rental. In the end I ended up taking my car to the BMW dealership after all. Their computer was kicking out codes that lead to the electronic valve, NOT the ECU. If I went to Pat I would have spent $400 for a problem I did not have and would have been charged more as he guess and checked his way to a solution at my expense. Before replacing the Electonic Valbe the mechanic at BMW changed my oil because this problem usually is a result of bad oil. Mind you, I got my last oil change from S2 Dynamics. After a couple days of getting my oil changed again, this time from BMW, my car is running just fine. Do not take your car here if you have a high performance vehicle such as mine. When in doubt, if something does not make sense to you, go for a second opinion. read more

1) Pat got the job done, BUT it took him a week longer than quoted, a lot of phone calls, many of which were unreturned, while my car sat at his shop. 2) Essentially bribes his customers with a coupon / gift certificate to post Yelp reviews, They are sitting in a stack on the check out counter. You write the review, then email him them a link, they email you the coupon. So not sure how reliable all these reviews are. Scott read more

Have had at least 3 repairs at S2. But recently took my car in because it wasn't running as expected. Patrick did an initial test and said he thought it was the injectors but needed for the car to be cold to be sure. So I left the car and he confirmed later in the day. However, I received a called from the Ops Manager(forgot his name) and said that the injectors were covered by an extended BMW warranty. S2 did not do the repairs and didn't charge me a dime! That's rare in today's world! Extremely honest and trustworthy shop! Highly recommend.... read more

If you have a European car and are looking for the best service and quality for a reasonable price look no further. I am so pleased with my experience here. I have a VW CC and the owner Pat has taken great care of me. Very professional and highly competent. I don't planing on going anywhere else! Highly recommend. read more

10/0 highly recommend! Got stuck on a project E30, Pat and his crew took care of it quickly. Wouldn't take my car anywhere else

I usually don't write reviews, but I just have to for S2. The quality and knowledge from this shop is truly remarkable. I'm very particular about who touches my car, I've modded my car(s), performance wise for some time. I've been taking my car (05' 330i ZHP) here since I bought it in September 12'; anywhere from performance modifications to regular maintenance, the jobs Pat and his staff have performed on my car have been stellar. I highly recommend S2 to anyone (especially foreign cars). read more

I have had Pat and his team service two of my BMW's and I have been more than pleased with his knowledge and expertise. It is always a pleasure going to S2 Dynamics they are the premier shop. read more

I first took my car to Pat (before his shop was S2 Dynamics) because he offered a better price on my Subaru's 30k service than the dealer. That was 7 years ago. Since then, he and his team have taken care of our family's cars through over 180,000 miles' worth of oil changes and other maintenance. Pat has always treated us honestly, explaining in detail what repairs he recommended - as well as what he thought could wait until the next oil change or two. For major repair work, it's rare and refreshing to find a shop that will answer every question about an estimate and invite you to get a second opinion. (The last time I tried that, the other shop - a big-name chain - tried to push a longer list of repairs that would have cost 50% more. And kept me waiting nearly an hour to get my car back when I told them I wanted to think about it.) Can you find a cheaper price for an oil change here or tire rotation there? Sure. But I know I can trust Pat and his S2 Dynamics team to help keep my family's cars running smoothly for years. That's what they've been doing so far! read more

Wow. After hearing some strange rattling near the passenger front wheel of my Audi S4, we decided to take it to S2 Dynamics. We walked in a Monday morning at exactly 8am, and they were able to look at my car on the same day. They started it, drove it around, and looked at everything they could think of, but still couldn't find a problem. I was relieved of course, and I could NOT believe that they did not charge me for spending at least an hour (probably more) tinkering with my car. Excellent customer service! We will be back when I have a non-imaginary Audi problem. read more

Currently driving a BMW 2007 335xi & paid a lot of money for maintenance at the dealerships. Then a friend of mine recommended me to go here and I am very very glad that I did come here. I dropped the car off late Thursday afternoon and had it back by Friday morning! I was impressed with how fast the work was completed. :) He Overall, awesome service, knowledgeable, and affordable prices!! I will most likely come back for future services. Whoo! read more

I moved to the area a couple years ago and wanted to find a mechanic that was familiar with Minis/BMW and could be a place that I could trust. I found everything at S2 Dynamics that I needed to be confident that my car and I were treated with respect. Pat and his team are super nice and willing to be patient and thorough and they instill professionalism in everything they do and I really appreciate their efforts. I cannot say enough good things and highly recommend them! read more

Pat and his team are the best. Service is always timely, thorough, and honest at S2dynamics. You'll never be sold service that your vehicle doesn't need. I recommend S2dynamics to all of my friends and family. read more

This was my first big service that was not at a BMW dealership. They did front and rear brakes, and all seems good. They were closing early that day, but had the parts delivered and did the work while I waited - maybe 2.5 hours. I will go back. read more

I am so thankful for these reviews. I had gotten an incredibly high quote for a repair from Marten's in Bethesda for my 2001 Beetle...they advised me of repairs I needed that I honestly didn't think I needed since I just bought the car and it passed inspection. I'm so happy I went to S2 - Pat is SO honest and knowledgeable. He took the time to tell me about his experiences with Beetles, his guess on what the problem was, and the final diagnosis. I saved myself $1,600 coming here - I've found my new repair shop! Thanks, Pat & crew! You've got yourself a new loyal customer - who loves Yelp ;) read more

These guys are really great and you can tell that they are honest! I took my car to them for an inspection and had them do some other repairs. Patrick is very thorough and helpful! read more

S2 is the best indie I've found in the area to work on my Saab 9-3 Aero. They've done everything from aftermarket suspension mods to OEM driveshaft replacements. Not often can you find a reliable shop that can help a car guy on jobs that are a bit too involved for a driveway DIYer and maintain very fair pricing with such a high level of customer service. As my car continues to age, these guys keep her on the road. Their workmanship is fantastic and their level of customer service and knowledge is unmatched. I came here based on Yelp reviews, and I'm staying here based on first hand experience. Keep doing an awesome job. read more

Took my Audi RS4 in,,, about two months ago for service and so far everything is running perfectly. Oil change! brake fluid, new tires, brake pad and rotors. Met Pat and I can honestly tell you that this man is truthful and sincere... Has a really good vibe,,,, guess what I'm trying to say is that he is trustworthy which is really difficult to from Shops today, Thank you! read more

S2 Dynamics is outstanding! I worked with Dedrick. I told him my issue with my BMW 7 series and he know exactly what it was and how to fix it. The guys here are very knowledgeable on BMW and other German cars. I felt more of like a friend VS. customer because I was treated with the utmost respect. The prices are very reasonable. This is the only place I'll take my BMW from now on because I know it'll be done right. Anyone looking for an indy mechanic for your BMW or Audi, look no further than S2 Dynamics! read more

This is my first maintenance visit at s2. My car notified me to change rear brake pads. I had a first consult at another place and they told me that I need to replace rotors too. Patrick informed me that rotors are still thick, no replacement needed, just the brakes were prematurely worn out, probably by the previous owner( 23k only.) The invoice for brake pads replacement was much lower then I expected and I'm not talking about not changing the rotors which would double the invoice. Great! Thank you! read more

My first experience at S2 went smoothly from appointment to service completion (brake fluid service on a 2011 BMW 328xi). Reasonable prices, no hassle, friendly folks. I'll be back the next time service is required. PS: I am a refugee from the dealer now that my warranty has expired and was aghast, even though forewarned, at the dealer's proposed pricing for the same service. The $170 to replace the cabin air filter which I did myself in ten minutes for $20, was the tipping point. I guess someone has to pay for those swell loaner cars. read more

For the past 10 years I've been loyal to a great shop that's 30 miles away. This was fine as a single Volkswagen enthusiast with all the time in the world, but as a married man with a small baby, that location was no longer convenient for me. I found S2 when me and my wife's cars both took a dump in the same week. Pat was able to get both our cars in the shop the same week and got to work on them almost immediately. He was able to give me a nearly 100% accurate diagnosis over the phone why my car was reeking of gas. Both cars were ready in no time flat, and the prices were better than two other estimates I had gotten. I especially appreciate that the car was freshly hand washed and the steering wheel and shift knob was not all greased up (my pet peeve!!) - this was the icing on the cake! After one conversation with Pat, it's clear that he knows the inner workings and I have full confidence that he's providing the best care possible. I highly recommend S2 Dynamics. This is my new shop. read more

S2 Dynamics - Both our cars at the doctor's office. - Auto Repair Near Me - Rockville, Maryland

Great work and very good customer service. I brought in my 2006 BMW 750 Li for an oil change and noise coming from the front left wheel. I was ready to a suspension or ball joint problem but, after taking a look at the car, it was simply the brake pads. If it wasn't for the honesty of Patrick and his team, I would have been taken for a ride. They have won my service from here on out... read more

These guys took good care of my BMW X5 and filled my coolant when I had a scare without charge. Highly recommend. I am a regular here and plan to have my husband bring his car here too. Very nice and honest people! read more

So everybody hates going to the mechanic, because that means something is wrong with your car and it's super inconvenient to get to work, and you get my drift. Actually, I like to go to S2 Dynamics to talk to the guys that work there and learn so much about cars and my car specifically. Yeah it sucks when my car is broken, but if I have to take it in to get it fixed I prefer to take it to this place. Today is a perfect example of why I trust this place. I was getting some intermittent indicator lights, and the chief mechanic there thought it was a wheel sensor which is over $100 part. He ordered the part. Turns out they just needed to clean it off and reconnect it, problem solved! I got out of there just paying a little bit of labor but the honesty is what I like. read more

Pat and team are trustworthy, professional and know their stuff. I've been using S2 for 3 years now and find it worth the trip from Capitol Hill when my BMW needs servicing. Their prices are fair and they guarantee their work. You'll get much better personal service at a much lower price than you would from any area dealer. S2 Dynamics gets high accolades from me! read more

My experience has always been good; I've been going to Pat for years and I can honestly say I don't know of a better mechanic. He always does the work the right way, and he actually notices other things wrong with the car and tells you about them and if they're critical, and is honest. read more

The team is always informative and transparent regarding repairs needed. Never pressured into making decisions on the spot. They fit me in the schedule and still make deadlines. Quality work read more

Pat and Eddie we're awesome. Pat worked on my car's trunk until the problem was fixed. I'll be bringing my Audi back!

The customer service amazed me! This place genuinely takes care of their customers and have fair pricing. I never thought I'd find a car place like this and can't recommend it enough. The fact that I'm taking the time to write a review speaks volumes on how satisfied I was as a customer here. read more

Fast and excellent alignment service and also they ran the computer checking for me w/o extra charge.

I can honestly say I have had the BEST car repair experience at S2Dynamics in Rockville MD - and I cannot say enough good things about Pat and his team. I came across their name on my local DC listserv and I am so grateful that I did. Pat and his team are so knowledgeable, and they answered all my questions with great respect. They did not try to up-sell me or unnecessarily add anything - it was just a totally honest, up front conversation about what I need to expect over the next year to keep my car in great shape. It was such a refreshing and pleasant experience and the cost was MUCH less than going to a dealership. Pat and his team really know their stuff when it comes to German luxury cars - I learned so much. I recommend them very highly and look forward to using them again. read more

Today was my first visit to S2 Dynamics. Truly impressed with the level of service received. Happy to say I've found my new go-to auto service. read more

As an update, I had some more work done on my wagon and once again had amazing customer service and quality work. I am so pleased to have them nearby and as my "go to shop" for everything. read more

I can't say enough about S2 Dynamics! The guys there really know there stuff. Pat was especially hospitable to me and really took his time with my '09 Volkswagen CC, which was worst case scenario. He always called me back with an update and was so very helpful. He is a very genuine person. I was expecting "Big Box" treatment but they really treated me like a customer should be treated. They made sure I understood what was going on in detail instead of leaving me in the dark. Their work is simply superb and above par. In short, if you want it done, done right and at the right price, S2 Dynamics is where you want to go. read more

I simply had a mount and alignment for some new tires that was desperately needed, as my tires were definitely worn and affecting the ride in my A4. Ordered the tires myself and had them shipped directly to the shop with no issues. The appointment took a bit longer than I was expecting (closer to 2.5 hours), but the waiting area was nice and I was using the WiFi to work. Ha, I might not have even noticed if another customer had not come in an hour after me and have their car finished before mine. Anyways, cost was very fair, much less expensive than what the dealer service dept was offering, and my ride is smooth again. Will definitely be the first people I think of if I have any other issues! read more

Pleasure to do business with. MD state inspection and repair. Will definitely use again.

Forget about going to the dealer, I have now the place i will be going to for all my car care needs, S2Dynamics keep my ride alive, thanks a million, my vw thanks you too! read more

I do a vast majority of my own work on my e46. But when a job requires more than what I have available to me in my driveway, Pat is the person I turn to. By far the most knowledgeable and fairest priced tech I have ever met. Will never go to another shop as long as he is available. read more

I've been taking my car to Pat for the past 6 years and have always had an excellent experience. I highly recommend S2 for their outstanding work and customer service. I am confident that every time I bring my car in they will do quality work at a reasonable price. read more

My BMW has 120,000 miles on it and S2 handles all my service and repairs. Pat and his team are honest, professional, and stand behind their work. Rates are fare and they never try to sell you on service that is not required. What else can you ask for. I wouldn't take my car to anyone else! read more
