hi any help my car is very under powered on cold start only for a about couple of minutes
im thinking it could be the egr valve clogged up the car is a audi a4 1.9tdi engine code BKE 54 plate 130500 on clock is it easy to clean or best to replace the part number is 038131501AD is this electronic operated because my car has a egr cooler on it as well but the egr valve looks totally different to normal vacuum operated ones thanks

i have never cleaned them only replaced them,and they are electronicaly operated, if the exhaust gass recirculation is not correct the engine management control light should light

i did mine a little while ago because i was told too by a mechanic who noticed oil on the side of the airbox intake pipe, to be honest he never said why i should do it but it would be a good idea because the wasted oil made the engine bay dirty

,easy enough to do just need a little patiance and small fingers, i found 5mm of coke buildup inside the body and it took a while to clean out but worth the effort. refitted in no time

, without exagerating the difference it made to the cars performance was incredible, better pedal responce and throttle responce, much much better

how easy it to do my car has a egr cooler on it aswell do you need any new gaskets to fit
here is a pic of my engine see the area circled the wire has a cut in it how can i fix this. Cut and join the wires up should i dissconnect the battery first this wire is for the manifold flap could this be causing the underpower when cold thanks
