German Autotech Inc.

I knew this young man before He was… His father (Jan Sr.) serviced my cars for years and became a great friend of mine. Jan sr had a son Jan jr and this boy grow up under the watchful eye of his master mechanic father and followed in his father’s footsteps in becoming a well versed, honest (a rarity in this field) and problem solving craftsmen in the biggest of jobs concerning an automobile… He is a true artist of fine tuning a car to perform at it’s highest. I am so happy to have found a home of reliable performing artist that work for the art first and financially blessings second. He works on my (1972) 280se MBZ, (1977) MBZ and my (1992) 400s and they all run like brand new cars… Thanks Jan Jr… you have made me as happy as your father did before his retirement

Jan is amazing! Very outgoing, friendly, and knowledgeable. I feel very safe taking my BMW 328i to him. He’s very reliable and honest which is very rare in the automotive industry. He’s always there to answer my questions and explain the problem and resolution.
There’s no need to take your car to the dealership for any type of repair — go see Jan! You’re in good hands with him!

Thanks again Jan. I took my Lamborghini Gallardo in because I was having multiple issues and the dealer wanted way to much money. Jan fixed my egear ecu, adjusted my egear so my car performs better, fixed my spoiler that did not work, and gave me a egear snap. he is the best. he did all this work and saved me thousands. if you have a Lamborghini I strongly suggest you go to german autotech. most places in the bay area over charge and usually are not that great. German autotech is trustworthy and knowledgeable and that’s why I trust them with all my cars and my families cars.

I am very happy that I found Jan at German Autotech. Previously, I had been taking my ’02 Lexus sc430 mostly to the dealer but when it came time to do the timing belt Jan was recommended to me (by a co-​worker) and his cost was much better. He recommended that I do several other things that made a big difference in how the car drove. I hadn’t noticed but he was right.
Great shop, honest, straight forward, they stand behind their work and a convenient location near to BART. Jan offered to drive me to BART but it is just a short walk.
I am happy to highly recommend German Autotech.

Overall: German Autotech (GA) is a shop I highly recommend to anyone who is looking for honest mechanics who care about their craft and clients. They really deserve 5+ stars. I will use this shop for all of my car repair needs.
Service: Excellent service with attention to details. Jan and Steve take their time to explain and communicate what needs to be done.
Knowledge: Expert master mechanics. They really know cars, and can fix anything (Lambos, Porsches, BMWs, etc). They can fabricate as well.
Quality: High quality and reliable work. They use only the best materials and products. I am fully satisfied with their workmanship. My Z4 runs stronger and smoother after coming to German Autotech.
Price: This is a value-​price shop. Although they are not the lowest, dollar for dollar they are the best value. For high-​end cars, getting the work done right will save you money in the long run!
My experience with German Autotech:
I started going to GA for about a year now, and my experience with them has been very positive. They use only the best materials and take time to do the job right.
German Autotech (GA) is in a class of its own. On numerous occasions when I took my Z4 in for service, I saw mechanics from other repair shops getting repair advice from Steve and Jan, the genius mechanics of German Autotech. I mean, these two dudes can fix anything; from the classics (MGs) to the ultra-​sports (Lambos), etc. These guys come from a pedigree of great mechanics; both of their fathers are retired mechanics.
More importantly, I feel I can always trust Jan and Steve. For example, I needed my brakes replaced. All the shops around wanted to replace the pads and rotors. Jan was the only mechanic who recommended to first check for wear on the rotors before replacing them. Turns out my rotors did not need to be replaced, which saved me money.
Other services I had done by GA on my Z4 included 6-​months service, transmission service, replaced oil filter housing seal and intake-​valves media cleaning. I highly recommend the media intake-​valve cleaning.

I have always been impressed with his attention to detail and his high standard of workmanship. When i bought my E320 Mercedes wagon, there’s no one else i would consider taking my car to. He took my wagon to another level. He lowered it with H and R springs, put on a set of C63 19 inch staggered wheels, high end Michelin tires, amg E55 front brakes, stainless steel header exhaust system, and then he put the super tune on the wagon by chipping the computer. The car handles and rides extremely well and it stops on a dime. He’s creative with his problem solving skills. And He’s reliable and honest on top of everything else.

Jan is a great guy. He knows his cars inside and out, and is more than happy to talk about them with you. He doesn’t give you a sense of entitlement, nor does he sugar coat things. They do great work here, and anyone with a German car would be a fool to not go here.

I brought in my husband’s older ford Taurus that he uses for a commute car that had many safety issues, brakes, front end problems that no one had addressed over the years or pushed us to fix, when I picked up car and drove home I couldn’t believe how it handled. Put new life into his car. Jan explained to me how dangerous it was for him to continue driving. I am very thankful it was fixed and glad not to worry every day. I trust the people who work there and now they are making my older Volvo safe for me to drive. Grateful to have this courteous and ethical shop in Walnut Creek.

German Autotech and Jan, were the best ever. He has worked on my Mercedes multiple times fixing every problem that no one else could fix. Lately though, he helped to really zip up the car and get new rims and wheels. Being a single woman, his help and kindness goes beyond words. Thanks Jan for being fun and professional.

I was so surprised by the treatment and service I received, after a long time friend referred me to this establishment.
I was talked to badly and insulted, when I went to ask the owner Jan, when I could pick up my car. He was more than unprofessional he was down right rude. He told me he would call me and that there were other appointments coming in and he would finish up my car when he could. He had already had my car for 3 days at this point.
When I did pick up the car we paid $ 1,000 more than the estimated price, The car had ½ tank of gas gone and 30 plus miles on my Audi! When I got in my car, my cell phone was no longer paired, like it had been prior to taking it to German Autotech. It was now paired to some guys phone named Gilbert! WTH!!!
It seems the owner allowed someone else to drive my car, when it was in for some intake cleaning. I am very nervous about the work that was done on my Audi. How can I trust anything German auto tech did?
DO NOT TAKE YOUR CAR TO GERMAN AUTOTECH!

Jan did a great job again on my 2003 Z4! He always recommends the proper service level for my car without braking my bank! Jan also explains, in appropriate detail, the repairs needed and provides education about how my car is designed to run, I learn something every time I get my car repaired by Jan.
He is always professional and pleasant to deal with.

Jan did a great job on my ’95 BMW E36 M3! It needed a new head gasket and I struggled to find the right guy for the job. My effort paid off as I found Jan’s German Autotech through a recommendation from an iconic local shop owner and a thorough reading of Jan’s Unilocal reviews.
Jan did an excellent job guiding me through my project. I received regular updates where he made recommendations and answered questions. Jan’s prices were fair and I received a 2 year warranty on his work.
When I picked up the finished product, Jan painstakingly walked me through all the old parts that had been replaced. From the old head gasket, to the broken smog parts and radiator it was clear that there was meticulous attention to detail.
Jan is a true expert on BMWs. He knew exactly what was involved and what options and updates were required. For the icing on the cake, he suggested a remanufactured vanos from Dr Vanos. WOW, this part makes the car faster than I ever remembered it. Jan also does a great job on the final touches — a little dent pulling here, a few faux wood parts glued back on there. He treats your car as if it is his own.
Usually, if someone tells me they are on a first name basis with their mechanic I get worried. That is definitely not the case with Jan — he will treat you and your car right!

Jan has taken care of our bmw for years and is an excellent diagnostician. The fact that our car is a 1997 and has over 250K miles speak for itself.

The owner, Jan, is fantastic! He treats my car like his own. Not only does he fix any problem that I bring him, he looks at everything else to see how he can optimize its performance. He is honest and extremely competent in his work and overall knowledge. I have complete trust in him to take care of my car and save me money along the way. He is not out to get you on a one time thing but work with you to help manage your car’s needs over its entire life. I tell all my friends about him and highly recommend him.

Jan is one of the best people I have ever worked with. First off he found a way to get us in for an initial diagnosis even though he was filled with appointments and then made sure he got us in as soon as possible to fix our issues. He was extremely thorough in checking out our Touareg and even helped us in deciding on the purchase of our new car. I highly recommend Jan as we will be using him for as long as we have a car.

I have brought in a vehicle outside of the usual European layout of the shop and each time the owner and primary mechanic has delivered expert diagnostics and results in fixing the vehicle, be it electrical or mechanical. My go to shop for honest and professional work!

Jan has worked on my BMW 330i on two recent occasions. He was recommended to me by someone who knows German cars and it was an excellent recommendation.
He has fixed a couple of problems with my engines and advised me of things to be
aware of insofar as the optimal performance of my car. It has been my experience
that really knowledgeable technicians of this type are not easy to find. So I
recommend Jan and German Autotech to anyone who needs a great specialist for
their German auto.

I brought in our Volvo fearing the worst but Jan insisted on taking the time to figure out what was wrong. He explained everything that he was doing in great detail and delivered the car in better shape than when it went into his shop. The car is in great shape and you would hardly know that it was worked on. He is extremely detailed and works hard to take great care of your car.
I can’t tell you how great it was to work with Jan. he is honest and really knows what he is doing. I will not bring any of my cars anywhere else.

Bringing a BMW to this shop is a must. This shop also specializes in higher end vehicles like Mercedes, Porsche, and Audi as well.
If you want quality, timely response, and great customer service, then German Autotech is the way to go.
The shop owner Jon is very knowledgeable and is one of the best experts on German engineering.
Moreover, his prices are the best in Walnut Creek, and if your anywhere around San Jose or the Bay Area, this shop is worth the drive to get quality 5 star service!

I brought my car to this place after I got a quote from another Mercedes place in Walnut Creek.
I am ALWAYS SKEPTICAL when it comes to having work done on my Mercedes.
So I arrive at German Autotech and meet this young man Jan. 1^st thing I notice is that he has about 6 mercedes in his lot. (good sign he is busy). I tell him whats going on with my car. He then tells me exactly what mercedes told me and quoted me without even looking under the hood. His price was less then the other place by far. I did have to wait for him to do the work (2days) but it was well worth it! All annoying engine lights off and my car runs perfect again. This guy is a Mercedes and BMW Expert.
