Great service - Ryan and company took care of servicing my 2011 328i and even gave it a full look over while they were at it. I'm selling the car and having a full run down of the condition prior to sale is super helpful. Highly recommend this shop for your auto repair, BMWs especially. read more

Ryan is the best! I usually do not write reviews, but the service I have received at OC German Auto Repair deserves recognition. I have been taking both of my Audi's to Ryan for just about a year now. His prices are great, his work is professional, and he offers quick turnaround times. He is extremely helpful and is always willing to spend the time to make sure all my questions are answered. From basic maintenance to installation of aftermarket parts, you cannot go wrong with OC German Auto Repair. Thank you Ryan! read more

Unfortunately last week my Cadillac Escalade was in super bad shape after my fuel pump went out...after having it towed home and leaving it parked on the street for the evening some moron tried to steal it, busting the ignition, steering column, and passenger side door. Really bummed me out!!! Thanks to Ryan Dieckmeyer over at OC German Auto Repair it was all fixed in No time. Had my truck towed over there around noon, and before the end of the day he had it all in perfect condition and ready to be picked up by 5:00 Quick, efficient, and affordable, with such a great attitude! I literally paid probably half the price anywhere else quoted me in half the time as well. I would highly recommend anybody to go there who is looking for a professional mechanic, with excellent customer service, at an affordable rate. Thanks Ryan!!!! read more

1) I had an 1998 E320 Mercedes that was running really badly. Ryan diagnosed it as a bad coil. The service quickly got the car fixed and now it runs great! I was very impressed. 2) Raul S has no idea what transpired. I am familiar with that situation. I don't think Jennifer is being truthful at all. Larry Pearl did all he could for her and more in spite of her verbal abuse. 3) In my opinion Larry Pearl is the hardest working wholesale auto dealer I've ever met. read more

Ryan and his team are fantastic. Our first time here he fixed a check engine issue on our Audi and repaired our glove department hinge. They are very quick, communicative and quoted a very good price. He went out of his way to save us money and giving expert advice of what was needed and what was optional down the road if we wanted a window switch replaced in the back seat. I had asked for a repair and a couple minor quotes little for misc. things. After this first great experience we brought him our Mercedes to repair before smog test. Again Ryan and Zach went out of their way to diagnose the repairs quickly, quoted the price up front, and performed the work. They had the car ready for smog, tested everything before I picked it up and once again a solid repair with attention to detail. They truly go above and beyond with their customer service. We would recommend this shop to everyone. We found them here on yelp. Looking for someone who is honest and professional. OC German is as good as all the reviews say. read more

THE only European auto O.C. alternative to the high-priced dealerships and other private garages. Ryan cannot be beat - price or quality. Highly qualified in his craft, Ryan gives you that honest, personal service that is extremely rare today. In this day and age of the garage rip-off/unnecessary and shady upselling practices, it is essential to forge a good relationship with an honest mechanic. Forge one immediately with Ryan; he is truly a mechanic that will pay dividends for you in the long run. read more

Ryan is the man! When my 2013 BMW 328i needed the brakes done, i reached out to my friends on Facebook to get a referral. That's how I came to use Ryan at OC German Auto Repair in Costa Mesa. I remembered meeting Ryan downtown one night with friends & he gave me his card and said if I ever needed any work done, he would hook me up. Now a lot of people hand out cards & say they'll hook you up when their out at the bars with a few beers in them, usually it's a different story when you take them up on their offer. Ryan came highly recommended by one of my girlfriends so I figured I'd give him a try. My original quote was from Discount Tire on Beach Blvd. I usually go there for brake pads, rotors etc. They always do good work & give me decent prices. No complaints about their service. The estimate I got from Discount Tire was roughly $650 to do my brakes. So I called Ryan with the quote & he told me to bring my car down & that he should be able to knock a few bucks off the bill. Well, to make a long story short. Just a few hours later & $200 cash, I was back on the road. My brakes worked like new & haven't had a problem with them since. I highly recommend Ryan's shop OC German Auto Repair. Especially if your car is out of warranty. Service & repair on these German cars aren't cheap. Ryan's not like most mechanics, looking to upsell & charge you for parts you don't need. He provides an honest & professional service at more than fair prices. And if you're looking for a deal on a used German car, check Ryan out as well. He's always got a gem or 2 that he's looking to sell for a sell for a steal. Thanks again Ryan for the great service! You're my go to mechanic from here on out. I can't recommend "OC German Auto Repair" enough. K. read more

Called to ask them about the timing chain tensioner issue with Audi's and the guy who answer didn't even know audi's had a timing chain and started talking about the belt. When I asked if he knew about the class action suit he said no and hung up on me.. Either they are too busy to talk to a potential customer or just don't know anything about audi's, but I can't take my car to them either way. read more

Ryan is the best. I won't take my car anywhere else. He has fixed and maintained my 335 on multiple occasions - every time I felt like I was getting great service and a great price. I highly recommend OC German. read more

Very reliable, trustworthy and knows German and other makes well. Truly a treasure to find them and a loyal customer.

Very easy to get to off Newport Blvd behind the old Grant Boys close to Harbor Blvd. read more

I was referred to Ryan by a friend of mine who said he was an awesome, fair and honest mechanic and he was right! I can't say enough good things about Ryan. He was friendly, knowledgable and very competent on every level you want when your dropping off your car and entrusting that person to know what they are doing. I dropped off my VW Tiguan for brake service and he was fast, honest and very very reasonable. I would highly recommend and will refer Ryan to any and all of my friends looking for that one thing that is so hard to find .... A great trustworthy mechanic!! read more

Ryan takes care of you and can be trusted to give you quality service at an affordable price. If your warranty is over bring you German Car to him and he will take care of you promptly and tell you the truth. I will now only takes my BMW to him and have talked my ex into doing the same. I highly recommend this guy to anyone!!! No one in OC can beat his prices and knowledge. I'm not some uneducated person either I was a manager at Daimler Chrysler in their powertrain group for four years and he is legit!!!! read more

Ryan and Zack worked on my Porsche Macan with fantastic results. They did the job quickly, without rushing or cutting corners. Could not be happier with the quality of service and the price. Even though I live in Aliso Viejo, I will always make the drive to OC German. Well worth the peace of mind that my car is being fixed correctly and fairly. Thanks Ryan (and Zack) read more

I have owned 3 BMWs and we all know they can be costly once the warranty is up, luckily my dad being a mechanic, has always been the only person I trust to do the maintenance on them after warranty. Now that I live in OC away from my dad I have been looking for a trusty, good, honest mechanic.... Well I found one!!!! Ryan is awesome and I won't take my car anywhere else now!!! Thank You! You've definitely got my referrals read more

Ryan was fair and open about his pricing he will work on my cars! You must stop by and meet Ratchet.

These guys were super helpful- came here in a state as my car was overheating. I know nothing about cars beyond being able to point out bits of the engine. They took care of the issue, handled talking it over with the man in charge- even told him issues they would recommend looking at and which parts needed to be replaced. Would highly recommend. Added plus: SUPER cute German Shep Pup read more

Just took my Audi A5 in there today. Ryan and his staff were very friendly and knowledgeable. They got me in the same day and did the service quickly. The local dealership quoted over twice the price for the same service and said it would take about a week to get my car in. Ryan saved me HUNDREDS! Highly recommend this place and will definitely be back. read more

My friend and I came in here to just to see if someone could look at a car before we purchased it and Ryan was so nice and honest. Safe to say I won't be going anywhere else ! read more

Read all the reviews on Yelp and OC German is the best. Dropped my car off at 12N and Ryan made the necessary repairs at half the price of the dealership and was done by 5pm same day. Excited to have found a good neighborhood mechanic. read more

Best place I've been in terms of customer service and professional method of carrying out business, and ensuring quality. Ryan has always been great, a real gentleman. Can already tell I'll be bringing my 2013 328i back here and only here. No complaints. read more

Was referred by a friend to go to Ryan since I needed to get the oil changed on my 2006 Bmw 530i, I also had a couple other issues I wanted to ask him about since I was there and he was more than willing to give me possible scenarios and even hooked up my car to check for any codes. While taking care of the oil change I noticed he did a check of my vehicle showing me what I might want to replace next time and somethings to replace now but without any extra pressure to do it which I appreciated, most other shops tell you what's wrong and what they need to do but don't really point out where the issue is and its current stage versus how it should be. Definitely recommend going to OC German Auto. Ryan will take care of u and ur car read more

I've spent years as a car and jet mechanic, but don't have the tools needed to maintain today's high tech sports cars. I've taken my 328i's to Ryan for 10yrs. I trust him completely. If he cannot do it, he knows others who can (e.g. wheel straightening, moon roof rework). As other smart shoppers have mentioned, Ryan's prices are awesome, but that is not what gets me to drive 50 miles for service. If you really care about your ride, Ryan is the mechanic you need to keep it in top shape. Near his shop are plenty of things to do; no need for a loaner car =). Thank you Ryan!!! read more

Ryan has taken great care of my 2002 X5 and even had a buyer for it. He did a full check on the 645 I just bought and found the battery was low and had a small oil leak. I took his notes back to the dealership and they fixed both issues. Thank you Ryan. read more

Ryan was awesome. He was able to get me a convenient appointment, diagnosed the issue, and fixed it very quickly without any hassles. Will definitely be back for any future car service needs. read more

What a blessing to find this place!! Ryan was quick to diagnose the problem wth my Audi A6..and they were more then willing to take my car in that day. They were friendly, work was reasonably priced, and the work was done by the following day. Highly reccomend them. Honesty and integrity are much appreciated..they went above and beyond what I expected! read more

I think overall these guys are honest guys but there are a couple issues I had a problem with when they worked on my audi that had check engine code for secondary air pump improper upstream flow. After paying them 900.00 the problem was still there, I did some research on youtube and came up with that the problem was the combination valve, which turns out to be a common thing in these cars, which was confirmed when I took it to Mesa Center Auto. Secondly, they lost one of audi centercaps off one of my rims which are around 65.00 to replace, and the plastic moulding on the bottom of the windscreen is popping up on one side and this moulding is what keeps water from running into your engine compartment. And last, I found two torx screws laying on the inside of the fenders in the engine compartment that were not reinstalled to wherever they were removed from. Still a dependable shop with friendly personel. read more

I started going to see Ryan with by 1984 BMW 3 series Convertible (in college.) Fast forward 10 years and I took Ryan my wife's 2006 X3 (which he later found a buyer for.) Now I take him my 2012 BMW X5 (for the not covered under warranty maintenance stuff.) Ryan is always fair... and an all around good guy. Definitely recommend him (and have to my friends.) read more

I have a 2007 335i that needed work and the BMW dealer wanted way to much to fix it. By chance I found Ryan and he did the work for a faction of what the dealer wanted. Thanks to Ryan we are very happy. read more

my 80yr old mom took her 98 buick le cross to ryan for a simple oil change and to have a couple of other things checked out and he charged her 120 dollars for a oil change. what a rip off its a buick mind you not a newer benz or porsche or beemer a buick hell aaa did a servay and the average price in the greater so cal for a synthetic oil change should have cost her no more then 70 bucks thats damn near double of what it should have cost.i was in the auto repair business for 16yrs with goodyear and would have been shoot dead if i even thought of taking advantage of a 80 year old person with a older buick thats just unheard of he should be ashamed of himself thats the kind of thing that gives the auto repair business a bad rap if you have an older american car youd be better off taking it someplace that respects its clients more then there pocketbook after all with out people there is no business shame on you ryan.... read more
