A4 1.9TDi judder when accelerating hard in 4th and 5th
i have a 2005 Audi A4 s-line 1.9TDi 115ps that i have recently had re-mapped to approx. 150-160bhp.
Ever since the remap (which has made a phenominal difference and transformed the way the car drives by the way!) there is a noticable judder when accelerating hard in 4th and 5th gears from approx. 1500 - 1900 rpm (when rolling at approx 50mph and booting the throttle) - it doesnt do it if you feed the throttle in only when you foot it.
There were no noticable problems before the re-map so i am assumining the problem is related to the increase in power and torque.
Any ideas what is causing the judder, is it causing damage to my engine and is it fixable?
