Hi all.
I now seem to be suffering with yet another ' common ' problem with my 54 plate Altea 2.0Tdi Sport which has only done 52,000 miles and I have owned for 6 years.Having suffered with brake pedal switch failure, throttle acctuator issues, back lights with a mind of there own, a music system which turned itself on during the night and am still saving to get the traction control fixed, the turbo is now deciding to play up......
After leaving the car for a week at Gatwick airport I set off North for the 180 mile journey home. All was fine for the first 40 miles of motorway driving. Then on the approach to an incline I depressed the accelerator a bit further to maintain the 80 mph in 6th; instead of maintaining speed though the car started to slow, throttle pressed further and still slowing, dropped to fifth and just managed to maintain 50mph uphill with accelerator flat to the floor. It then dawned on me that there was no turbo boost apparent. But no warning lights, no strange noises etc etc ?? I then had an 'interesting' further 140 miles of motorway with no turbo. The car still did 53mpg though. ( was unaware that turning off ignition would reset!)
Next morning checked all the obvious and everything appeared ok. Started the car sounds normal and turbo spooling up - no smoke from exhaust. Upon driving the car turbo was back, but not quite as before.
2 weeks on and no total turbo loss BUT it's not quite right( have yet to do a sustained motorway journey). The turbo now appears to spool up 600rpm further up the rev range; before the above journey it would come in around 1300rpm and be on good boost by 1600 and get stronger from there. Now it is flat until almost 2000rpm when it builds boost and then goes as before.
The turbo is now virtually silent whereas before it was clear when it was coming in / dumping gases ???
Car still doing great MPG ( virtually always in the 50mpg+), oil clean, not smoking, no stuttering or missing when accelerating etc
Having read previous posts I have given it a good thrashing to decoke the turbo and apart from it's lack of bottom end torque all is fine. This has not improved anything.
Am now unsure where to go MAF sensor, turbo had it, leak in a pipe, wastegate stuck ?????
Other than the character building issues I love the car, the economy and performance.
Any idea's would be much appreciated .......
