Hi all - new to this forum. AF - your posts are incredibly helpful. Have a stock B8 2011 S4 that I have babied - all maintenance and very low miles - 48k. Was driving from Houston to Dallas and felt a little frisky - was going ~100mph over a fairly long stretch, and suddenly got full limp mode and no odd gears. Towed to dealer, code was clutch 1 temp too hot, reduced torque. Dealer didn’t want to touch, saying need new tranny. Had a reputable local garage drop the pan - no shavings or burned smell - has me thinking it’s likely mech unit.
Had the garage perform the mech repair per the TSB - still no luck, cleared codes and the temp code came back, even at a cold start. Could it be a bad temp sensor or perhaps the cooling valves? For now, I asked the garage to drop the mech unit again and I’ll test the resistance on the solenoids - any other suggestions? Much appreciated!
