Hi.
6R Tdi 7sp. No power loss. Good economy. Runs well. Mostly drive with windows down and no aircon. 100km each way to work and back. Travel mostly at 100km/hr nearly always on cruise. Curently at 228,000km.
For about 8 months when going up a slight hill I thought it was cicadas. Now I can hear the noise come on and off as power comes on uphill with windows shut. Not screaming but a squeal sound. It can be heard on the flat as I accelerate from about 1500rpm to about 2500rpm. Not in the low gears though. Not when sitting in neutral or park(no load).
There is oil around the intake to the turbo, from the hose that comes from the rear top of the engine, which I assume is recirc pollution stuff.
Any hints as to what it may be?
Thanks.
Neil
