I have a 130 TDI, which yesterday without warning lost power, while I was on the motorway. Also when driving normally there was no turbo whistle and it felt as if the turbo was not working.
Started the car later in the evening and all was back to normal. I have been advised there may be a possibly problem with the boost control or airflow units. Anybody had similar problems or any ideas. I plan to get a remap in the near future and am a bit worried about an underlying problem.
Cheers
Ian
