These guys ROCK! I just moved to the city from Colorado and had to get my car through the dreaded smog check. Failed the first attempt. Fellow VW owners feel my check engine light pain!? It passed emissions but had a bunch of computer errors, so the light would not go off!After one bad experience with another shop, I found Advanced Autowerks on Yelp. Took my car in, had some work done, the light came back on - took it back in and explained to the shop owner (I think..?), Randy, my situation and that i was afraid of going upside down on my car value since it's an older model and I'd already sunk a ton of money in it just to get it out here. Not only did he locate the final problem and resolve it for reasonable money, but he took it to smog check for me and saved me the final headache!!!Thank you Randy!! You will have my biz from now on!! Advanced Autowerks is the BEST!
