Hello everyone!! i signed up today just because i have an 2000 a6 2.7 tt but!! as you can tell by my username i have a gm product haha. Anyway tha audi is stock im just running full synthetic oil(royal purple) anyway...3 days ago i filled up at chevron . i put the 87 in with techron(first time ever at a chevron) and weve always used 87 octane. anyway so the whole chevron deal made the car hard to start and blah blah i let it go down to about a quarter tank...and then i filled up with the normal 87 and today it didnt even start at all...so i had to get it towed to this special german mechanic...my dad and i would do it(were from switzerland and my dad has had tons of audis) anyway the whole system has to be flushed and we cant do it because of the whole -30C deal here in northern canada anyway i was just wondering if you guys have had the same issue?. also the cupholder in the dash is stuck out...would anyone help me with that? but yeah just wondering if you guys had an input??..=)
