Hello.
I have an Audi A4 2.0 TFSI
It's so that my car has a really troublesome problem. When I accelerate, the car is oscillating in acceleration, but it is only up to 4000rpm. After 4000rpm it goes without the slightest doubt. Have had it on countless workshop visits. Checked out the forum.
What I have changed is.
Vvl valves 8pcs
Maf Sensor
Map sensor
Spark plug
Ignition coils
Charge pressure valve.
The inverter dump valve
I thought the car became more swaying after I removed 3 of the 4 mufflers on the exhaust system. (can also be imagination)
The car is chipped. The only non audi part is the dump (dv+) which is an aftermarket that should be more durable than the original.
Would be amazing if someone sat inside with the answer to the problem.
Regards Jocke
