Hey guys hopefully some one has an answer for me as i have searched all the forums and always come up empty handed. Seems like a lot of people have had similar trouble..

Car : A4 2009 2L turbo
Recent Repairs : timing chain and all seals tensioner etc, diverter valve (d)

Problem i am having is a hickup when im accelerating!! The car will lag a bit when i hit 3000rpm for a bref second then continue accelerating, its as if its losing power.

No check engine/no codes
turbo is good and boost holds

always have had this problem but now its a lot more obvious since i had it remapped Unitronic stage 1.

My mechanic doesnt know what the problem is.. i hope some with first hand experience can tell me what they did to fix the issue!!?

fuel pump?? Fuel filter??

My son's 2010 A4 had a similar problem. Sporadic miss, and finally got to the point of rough idle. Bad coil pack. 41,000 miles.
