My BMW started making strange noises, so I knew I had to take it to a mechanic. RA Motorwerkz was recommended to me from one FB groups and I decided to try them. Rodion was easy to get hold of for an appointment; opinion of what repair my car needs was given very quickly; Rodion even had similar part of the car on his table as an example, and he showed me what exactly happened with it, how they are going to fix it, and what NOT to do to prevent it from happening again. Being a detail oriented and curious person, I appreciate the explanation a lot. The car was fixed shortly, thanks to the entire RA Motorwerkz team and technicians . Rodion also recommended, how to fix an additional, cosmetic issue on the door handle, and he ordered and installed the door handle kit for me while working on the main issue! Highly recommending RA Motorwerkz team! read more

Rod is great, i had him replace my Transmission in my F10 and was installed and program in a timely manner. I also had a Vacuum leak, Alan found it and fixed it. This was great because my car was in for a transmission service, not for Vacuum leak. Car runs much better now. I live in Tracy, I now found a new spot to take care of my BMW Mercedes needs. read more

After buying my BMW 335is with ~140k miles, I wanted to do things the right way. The car had known oil leaks (valve cover and oil filter housing gasket), and my goal was to fix everything properly so the car runs right and lasts, without paying dealership prices for obvious issues. I'm very glad I came to RA Motorwerkz. From the start, communication was excellent. This was my first time here, and he kept me in the loop with photos, clear explanations, and showed me exactly where leaks were coming from. I never felt pressured into any work. If he recommended something, it was because it genuinely made sense while things were already apart (vacuum lines, cooling hoses, PCV components, boost solenoids, etc.), and everything was discussed beforehand. What really stood out was his understanding of the N54 platform. Labor was bundled intelligently instead of being charged separately like a dealer would, and the pricing was honest and fair for the amount and difficulty of work involved, significantly less than multiple BMW dealer quotes I received. The work included addressing oil leaks, walnut blasting, PCV system refresh, cooling system items, boost-related components, and more. He also installed a charge pipe and cold air intakes I supplied at no extra labor since he was already in that area, which I really appreciated. The car now runs great: no leaks, smooth idle, boost is restored, and the walnut blast made a noticeable difference. He even followed up afterward to check how the car was driving and made it clear to reach out if anything felt off. If you care about your BMW being worked on correctly, want transparency, and don't want to pay inflated dealer prices, this is the kind of shop you're looking for. I'll definitely be coming back. read more

This was my first time visiting RA Motorwerkz after getting my new-to-me BMW 428i, and I couldn't be happier with the experience. Communication was incredibly easy -- I was able to text them to set up a diagnostic appointment. The same day, I received a detailed report outlining the issues my car was having, along with a quote within a few hours. Scheduling a time to get several items fixed was quick and hassle-free. Repairs were completed on time and at a much better price than other shops had quoted me previously. Definitely a 5 shop. Clean facility, knowledgeable technicians, and great customer service. I'll definitely be coming back soon to get my brakes done! read more

Rod provided excellent work and advisory we it came to getting my E30 back on the road. Knew exactly what parts I needed. Highly recommended for any classic BMW needs. Thanks! read more

I am obliged to highly recommend RA Motorwerkz for the work done on my older BMW. Rodion, my mechanic, pays attention to every detail and specification, insuring the job is done properly. Recently Rodion did a transmission replacement, and now the car runs smoother than when the original transmission was fully functioning. I also use this business for routine maintenance and will continue to do so for future peace of mind. read more

I was looking to get my A/C compressor replaced for a while on my E90 (BMW 330i) and decided to take it to RA to get it done. Rod was able to get me in quickly and got the job done just as fast. He was transparent and kept me updated about the status of the job throughout the repair, even pointing out a few potential trouble spots on my car unrelated to the repair, which I appreciated. Pricing was extremely fair compared to other quotes I received. I highly recommend RA to anyone looking to get their BMW serviced. read more

Please do not go to him. I had a transmission installed on my 1968 Camaro by him and he was confident that he could do it correctly and did not. 1. The output seal was leaking and i sent him a video to ask when i can bring it in he said he is super busy i said ok. Next week asked him again because i brought it to a 2nd mechanic and the reason it was leaking because the drive shaft was too long and asked Rod when can i bring it in he said "let me figure it out" and i never heard back from till this day! 2. The transmission has a slipping problem and he does not care to even fix it and he did not even try to drive the car because he said it would not start. Mind you we gave him the car when it started and he told my dad and i he can keep the car and figure it out but would rather not work on it, so we had it towed home and to do our own digging we seen that the starter wire was tied up hidden and we put a new starter in and plugged it in and it started up perfectly. So the thought of bringing it back to him makes me think he will sabotage the car more just to get more money out of me. So now Theres a possibility where i have to get the transmission redone. 3. He will ask you to cash app him to pay his workers that he cannot pay himself. We sent him a total of $5k for horrible work that we have to just eat and go get it fixed by people who know what they are doing. He will not send you an invoice so beware! 4. Till this day he has not reached out to fix what he messed up. read more

I highly recommend RA Motorwerkz! My SUV was having complicated issues that a dealer misdiagnosed. I called Motorwerkz for a second opinion as they came highly recommended. Rodion quickly diagnosed & repaired the issues. He responded immediately & got me in the same day. He figured out the issues, made the repairs & got my car back to me faster than expected! I saved hundreds & also avoided having to rent a car! Five stars for these guys!! read more

RA Motorwerkz impressed me with exceptional service and expertise. They performed meticulous rod bearing replacements on my E46 and E92 M3, performed a full SMG and DCT service, and fixed my leaking DCT pan (common issue). Their transparent and fair pricing exceeded my expectations. The team's passion and knowledge instilled confidence, especially as I look forward to getting my E46 M3 manual swapped once the SMG requires a costly repair. I plan to continue bringing my vehicles here for maintenance, including my X3 once my BMW service expires. RA Motorwerkz has earned my loyalty, and I highly recommend them to fellow BMW enthusiasts for their unmatched service quality. If you seek a trusted partner for BMW maintenance with expertise, fair pricing, and genuine passion, look no further than RA Motorwerkz. They are my go-to choice, and I'm confident they will impress you too! read more

I called Rod when I had an issue with my Audi Q5 diesel. He was extremely prompt in reaching out to me and provided great advice on how to handle. He left such a good impression that I got a portion of the work done at the dealer that was under warranty and then gave him the rest of my business. I will definitely be using him again for any future car repairs and would be happy to refer him to my friends and family. read more

The owner Rod is a great guy to work with. He definitely knows what he's doing. Honest and trustworthy. The job was done quickly, efficiently, and the price was fair. I would not hesitate to take our BMW to them for any work that's needed. Thank you for the great job. Work performed on our 2008 BMW X3: Replaced the drive shaft (common issues on these X3), resealed the leaking rear differential and added new fluid, repaired a coolant leak that other shop had thought was the reservoir tank but turns out it was a small gasket (great quick trouble shooting by Rod, he sure knows these cars).

Not sure about all the reviews for RA Motorwerkz and Rod. I can't speak to his diagnostic abilities or his responsiveness for his repair customers. I can; however, speak to his business ethics and morals. I bought a S54 motor from him that he was selling on Craigslist and dropped off a second S54 motor for him to put on a pallet and ship to me. I had a friend check Rod's motor and his shop while dropping off the second motor and everything seemed legit. However, when I received the delivery, I found that Rod had not sent the complete motor I purchased but just the block (the difference is about $1K in accessories that I was planning to remove and sell to help with the cost of the motor). In addition, Rod removed the exhaust manifold from the second motor without my permission--I believe that's called stealing, at least in my book. I tried to reach out to Rod after I received the engines to make things right, but after a feeble "I'll offer you a good trade for the exhaust headers that I removed" he quickly blocked my cell number. While I was visiting family near his shop, I tried to drop by to see if Rod wanted to make things right. I met a fellow at the shop who spoke perfect English until I mentioned that I needed to speak to Rod about a problem. Then he said "English no good". I have no idea what Rod looks like and that could have been him for all I know. I even texted Rod from my other phone number giving him yet another opportunity to make things right, but no response. And here we are--I try not to post these types of reviews as I feel they come off as whining and entitled, but it's the only avenue I have with Rod and RA Motorwerkz to try to be made whole. read more
