Hello,
I've just changed TCM on my audi, after replacing it ($2.500 later)my previous problem went away (blinking red PRND, sometimes wouldn't go reverse) but now I have another issue..Like I mentioned when I am slowly accelerating from a stop just when I reach 20mph it jerks couple of times and then as I go faster you can't feel it anymore.If I speed up faster from 0 (step on it) it doesn't jerk...Tried to change coils, spark plugs..nothing

please anybody,
any advice is good..

 

I have the same problem and looking for a colution. I am going to check few things such as spark plugs, coils, gap for plugs etc.

 

Done that, changed sparkplugs, 4 new coils, oil and air filter..I am changing the fuel filter on thursday hopefully...

 

fuel filter wont help...done that

 

Have you changed the bosch ignition control module on the airbox?! That is what controls your coils.
