I have an Audi A3 2007 2.0 TDi 170 bhp BMN engine code which occasionally flags EGR or port runner DTC (not always) the problem is only from cold and within 400 yards on acceleration it cuts out just like the ignition is switched off but if you release the accelerator pedal it wont cut out the rev counter does fluctuate quite a bit (I'm thinking is a power fault anyway) after 15 seconds of hucking and jerking it stops and runs normally for the rest of the day and wont do it again until its cold (4 or more hours).
I have swapped fusebox with a known runner including the relay unplugged the throttle flap and the EGR still no different VCDS wont log it because I have to start the engine then start logging by the time I've done all that it doesn't do it...
