Hi Everyone,
New to the forum and 1st time Audi owner as of February. Hopefully I'm posting in the right section.
In the last week I've noticed slightly lackluster performance in my A5 3.2 manual Quattro (65k miles). Acceleration seems somewhat slower. I noticed that when in neutral with the clutch engaged (pedal out) and I rev the motor, its slow to gain speed and the rpms stay high for a second or two before dropping. My cruise control isn't functioning either. I dont have any signs of a slipping clutch. From reading other posts (all on the S5) it sounds like I might have a bad clutch switch (one of two) . Two questions: 1# Is my assumption most likely correct about the cause of the issue and. 2# Where can i find the part? I've checked all over and it's not listed anywhere, even on the official Audi parts page. The closest dealer is a ways away and Id like to get an Idea of whats going on as its going to be a few days before I can get there. Thanks everybody.
