There's been a hesitation on my A3 (PD140) that was happening around 1500-2100rpm on part throttle.
After various attempts to fix the problem, it turns out that by disconnecting the vacuum pipe to the EGR cures the hesitation completely.
I'm not going to leave the vacuum pipe disconnected as its going to throw an EML up, so i'm going to try a blanking pipe with the hole in the middle like a reducer to restrict exhaust flow back into the system.
Hopefully this will cure both the hesitation AND prevent an EML, if this doesn't work and I have to completely blank it all off, how do I go about 'mapping' the EGR out?
I already have an AMD remap and they want £150 to disable the EGR, is it possible with vag-com? And if so, anyone in the south east fancy doing it for me!!?
