I have a problem with my 2002 1.8 TDCi that is both very annoying and very embarrising at the same time. With a cold engine, it runs fine, no unusual noises and idles and revs correctly. Once I have been driving for approximately 20mins and the engine has reached running temperature, the car develops a very unusual sound when I'm accellerating and my revs reach around the 2000 mark. It sounds like what I can only describe as an elongated owl hoot (sounds stupid I know). Even when I lift my foot off the accellerator and the revs drop, it's still present and the dies down the lower the revs get.
Trying to cruise along in this nice hot weather, shades on windows down, stop at traffic lights, pretty girls walk by , accellerate off and my car does that . zero cool points for me!!!!
I hope it's not, but I think it may be something to do with the turbo. If it is, then this car is gonna be scrapped as I really can't afford anymore repairs on this car, especially not a new turbo anyway.
Has anyone else experienced this noise. Any advice/guidence will be much appreciated!!
