Wei is amazing. He is incredibly knowledgeable, professional, personable, reasonable and a very clear communicator. I recently attempted an unsuccessful software upgrade on my 2022 BMW 228i Gran Coupe. While guys at the BMW genius desk tried their hardest it was clear this was going to be an incredibly expensive undertaking at the dealership or no upgrade. Then I discovered Bay Area BMW Coding. From my first conversation with Wei it was clear he knew his stuff. He upgraded everything on the car (I bought the car used - no upgrades had been done since new) software and map updates. Wei is the best. Highest recommendation. read more

Brought my car back to life! I bricked my BMW's ECU/ DME after a failed flash with Bootmod3. My car would not start and dash was lit up like a Christmas tree. I called every performance tuning shop in the Bay and nobody had an answer. BMW told me I needed a new unit. Luckily I found Whelan. He was able to get my car running the same day and even helped me flash my car afterwards. This guy really knows his stuff and I really recommend him if you're facing a similar issue. - Fast and prompt communication - Above and beyond service - Very reasonable pricing - Highly Recommended! read more

I had my Footwell Module (FRM) go out on my bmw e92 when I disconnected/ reconnected my battery. He was able to help me last minute with fixing the module. I was in and out within 30 min. Couldn't be happier! Thank you so much! read more

Seems like a nice guy but honestly screwed me. I asked if he could unlock my f87 m2 and he replied yes with a price. I told him I would be driving 2 hours in from Lodi. When I arrive, I pop the hood and he goes "hmm where's the dme?? Ohh this is an m2, on all the M cars it's underneath the intake and stuff. You got any tools?" No man I just drove here from a couple hours away. Writing this as I drive the 2 hours back home for nothing. I'm sure he knows how to use the coding software just fine but he failed me. read more

Bay Area BMW Coding - Auto Repair Near Me

I needed a footwell module repair for a R56 Mini Cooper, and this guy in the whole entirety of the Bay Area is able to do the job at a reasonable price and relatively quick. Although I'm coming from South Bay, it was worth the drive up. He is communicative, informative, and knowledgeable specialist in anything BMW related. I highly recommend him for anything BMW-recoding and would do business again. read more

Wei...you are the BEST! I can't believe you figured out the issue with my CCC. I spent countless hours diagnosing fiber optic cable (amp, Bluetooth, iDrive controller, CCC unit)...watched tons of YouTube Videos and read tons of forums...and within just an hour...poof! He narrow it down to the Avin system (3rd party) giving all the issues. He put back the original CCC and all issues went away...like magic!! I couldn't believe my eyes...watching a pro work his magic...was both ecstatic and euphoric! I thought I had CCC issues, he ran bunch of test...CCC was responsive, iDrive controller is working just fine, all modules were just fine....plug Avin back on...all the issue came back on. That was one way to isolate the issue. I now unplug Avin and just use BMW CCC unit. Great guy...easy to talk to...he's definitely knowledgeable on the subject... Waiting for Avin to replace the unit and will try again to have CarPlay back on my car... Here's my issues with my 2007 BMW 328i convertible CCC - I had no sound, SOS on dashboard, door open without chime, CCC non-functional, iDrive controller non-functional... Thank you Wei for your knowledge and kindness... read more

Wei is top notch, super knowledgeable, always quick to answer any questions. When it comes to BMW Coding, his expertise is hard to beat. I had a vehicle with wrong FEM installed from previous owner, Wei was able to perfect match replacement FEM, coded it, made it so all my current keys still worked, car has been error free since, he's truly a life saver. read more

Had a bricked module due to a corrupt set of files I used (my own fault). Called this place to see if he would be available and was expecting at least a 24 hour lead time. I was in a jam and he was able to get my issue resolved in literally hours. He knows his stuff and could tell he was confident in his coding/craftsmanship. Would recommend this shop over any others especially when it comes to module repairs. I will be using his service in the future and probably ask him more technical questions that I normally cant get answered even on enthusiast discussion boards. read more

I had an issue with my BMW where my car was unable to recognize the key which resulted in the fact that my car was unable to start. Not having a clue to any solutions, I've contacted Wei from Bay Area BMW Coding. Wei gave me a quote, shockingly, precipitously cheaper than any shops. I was very pleased with his quote as it was much affordable than I thought! Our appointment was sharp and punctual. Wei was very professional and explained to me every aspect of why my car was unable to read the key. He was very thorough and articulate as he showed what was diagnosed and how he would fix it. Within just ten minutes my problem was fixed. I was thrilled and flabbergasted. In addition, not only did Wei fix my problem, he informed me of the potential problems of what my car will face and what I should be expecting in the near future. He gave recommendations and advisories from his professional perspective. Wei and his service were immaculate. He is a consultant and a genius. I cannot be any happier. He is truly an honest and generous professional. I own a few BMWs and I will definitely reach out to him for more services. His prices and services are unbeatable. I definitely recommend Bay Area BMW Coding. Truly a happy and satisfied customer! - Alan read more

Bay Area coding goes above and beyond every time. He sticks with the project until it's done and does everything he can for the best possible outcome. read more

Loved the experience even though the circumstances weren't ideal. FRM module had gone out, so I brought it in and he said the power failure in my cardestroyed my processor. Luckily he had another module that he just reprogrammed at no extra charge! Helpful, good communication, A+. Don't pay the mechanic or the dealership to fix your coding problems for your BMW because the price and service can't be beat here. read more

Repaired my mini cooper's footwell module on a holiday. In and out in half an hour. Guy really knows his stuff.

Nothing but impressed, I have had two cars taken care of and will certainly get back in touch if I need any other assistance. Incredible knowledge of the Bmw world and more than helpful in getting issues sorted out not just woith coding but with parts as well. I have a e70 and after some discussion we both felt it would be best not to drive it so Wei made a house call and sorted my issue out for me on my block, so thankful. Having used BMWs it not a matter of if but when there is going to be a problem, I feel better know that Bay Area BMW coding is around to help and solve any issue big or small. Great service, great prices, and overall a must have in you are a Beemer owner in the bay. Thanks so much for all of your help! read more

Bay Area BMW Coding - CAS,KEY,DME set! - Auto Repair Near Me

Was my fault I did not research enough to find out you can code some settings out on the e46 m3 for free, but this place charged me for a license fee of 200. Then later I wanted to get some of those codings fixed but he wanted 100 or 80 more to fix that. Shady and scandalous. Would not dare to do business with this person ever again. read more

Met Bay Area BMW Coder at a stoplight. He drives a 335i just like my 335i. I asked Wei if he knows a performance tuner in the area. He told me he tunes. He gave me his number. I texted him that day he gave me several scheduling options. I took my car to his house. He works out if his home. Wei performed the procedure. The procedure took just less than one hour....... Had test drive of the car WHOA absolutely wonderful. A great and noticeable improvement to my cars overall performance... Bottom line this is hands down the best performance improvement I've made on my car..... Wei has s bunch knowledge. He helped me with several items that were wrong with my car that were not code related.... The tune was well worth it.. I wish I would have taken the car to Bay Area BMW Coder sooner.......... If you're considering getting your 335i tuned. I highly recommended this tuner..... Good knowledge. All tools on site...Extremely affordable.... Money well spent read more
