My 2001 525d with 133000 miles on the clock has lost power a couple of times recently. Press the accelerator and nothing much happens and then the turbo kicks in belatedly. Took it into BMW who said that the diagnostic revealed no stored fault. They suggested replacing a small pipe and a sensor as the first stage to avoid heavy expense.
They did say however that there was a very small oil leak from the turbo which over time would only get worse. A new turbo would cost €1200 but they said that they could get a turbo rebuilt for a much lower cost with a 1 year guarantee against the 2 year guarantee of the new part.
Any one any experience of rebuilt turbos or any other advice in this area, please?
Darkhorse 737 Thanks for your response. I have always had the car serviced by BMW dealers in the UK and in Portugal and have done my own oil and filter changes halfway between the indicated service intervals. The air filter should have been changed when necessary but I will check it out.
I did not know how best to describe the lack of power. It has only happened a couple of times and when I pressed the accelerator pedal the engine only picked up slowly without any surge of power and then after some delay the turbo kicked in and the power came on strongly from about 3500 revs.
