hey everyone, i just brought my 335 in for service, and because the tire pressure symbol wasnt resetting. I left my turbo tuner installed because a buddy of mine is a head mechanic there.They ended up resetting the battery. Ever since i got my car back it feels alot faster than it did when i brought it in. is that possible or im just crazy.It took them a day and 1/2 to get it back to me too.In the the write up they gave me it says they attemped twice at reprograming the car but it failed, then went through the third time.something about the tcu failing, whats that all about?

what do you mean by resetting the battery? Never heard of batteries that can be reset, do you mean disconnected/reconnected?

I guess, thats how they stated it in the the print out they gave me
