My A4 2.5L tdi quattro Has started to exhaust blue/white smoke when idling after a normal run (ie at traffic lights). I suspect the crankcase oil breather is blocked. everything is normal at speed and there does not seem to be abnormal oil consumption.
Any ideas on how to check/clean the breather would be appreciated.
You should order a new one and change it before it starts to suck oil into your turbo.if u start yor engibe and open your oil filler cap there sholud be no overpressure.did this job my self just a few weeks agojust remeber to get the new model fomter designed for the new cars.the old one is a piece of **** and should newer be sold.send me yor emailand i will send you the part numbers and pictures+ the link on "how to do it"
