Ok, this brings up something that everyone with BMW's experience. The 1st to 2nd shift is incredibly notchy and dull. Thats because since around '92ish BMW was putting in something called a CDV(Clutch Delay Valve). Theres a modification for it that opens the valve up and releases the flow of fluid so that the transition is much smoother and quicker.

Im wondering if Audi has something like this installed in their clutch lines?

Well I made the appt for January 3rd. I hope this is my last trip to the dealer until my 5k service. The car has 2k on it and been to the dealer 2x this will be 3x

The BMW CDV is very pronounced, and if Audi has something similar they've done a good job with it.

To the OP, I don't have SD either and find that my car shifts great, and it gets better as the miles accumulate. I think yours has some issues that the dealer will have to resolve.

I played around on my way home last night to see if I could experience your issue... If I do not concentrate on matching the revs from 1-2 2-3 then it can be a rough transition. The revs drop so fast in this car I find that I need to shift faster than in my old S4 or my GTI. Makes it really hard to drive this car economically!

Maybe a short shifter would help the situation?

I'm aware of the CDV valve since my last car was a 335i. But, Im not sure there is a similar part in the S4. Many removed the CDV in their BMWs.

So r u feeling this is normal and may just need a sprint booster and faster clutch release?

2nd. My 6MT shifts great.

Possibly, it seems the faster I get in and out of gear the smoother it goes. Since I can't drive your car and experience it there is no way for me to quantify what is going on. Dynamic is easier than auto or comfort to progress smoothly.


Hope that it gets resolved to your satisfaction.

This is one of the best feeling manual transmissions I've ever driven, but there is definitely a learning curve. As said above, the RPMs drop really really fast in this car, and it takes a good amount of driving to get your muscle memory in place to shift smoothly 1st->2nd->3rd. Driving in dynamic mode helps with smooth shifting if you have SD/ADS.

My shop foreman over at Classic AUdi is awesome. They are replacing my entire clutch instead of just doing the TSB. He told me that just doing the TSB does not fix what damage the faulty parts could have done to the pressure plate etc. I told him about squeeling brakes he told me that its normal as he owns an A4 same problem. He said yes they can be modified but the modification takes a lot of like from the brake pads and some life off the rotors. He said he could do it if I wanted. I told him I will try to bed in the brakes again. He laughed and said that almost what the modification does anyway. Its shaving down the pads and rotors lol. Anyway I will hear back today about where the clutch is coming from whether here at the warehouse or from Germany. If its here than I will get my car back next wed or thur.
