My Ride: 320i
Weak 320D

hi guys
I am driving a 2002 model 320d, the car sometimes feels like it has no power and at other times it does have power. At times I feel the turbo coming in at around 2500-3000rpm , this I feel only in 2nd gear and sometimes in 3rd and at other times I don't feel it at all. I asked the previous owner and he told me that he had a new turbo fitted recently before he sold the car and that the problem is one of the vacuum pipes which is cracked , I changed the pipe and nothing changed. Also the car sometimes smells of burning oil , but the oil level doesn't go down. I noticed that it looks like it has a slight leak somewhere on the pipes for air around the turbo area but I have had the car for 2 months now and there is no sign of an oil leak on my garage floor. I had the car diagnosed by one mechanic and it showed an error for charge air pressure , that was before he replaced the broken vacuum hose. Am now thinking of having a compression test done and also having the cylinder head and valves serviced, maybe I will get better performance. Anyone else been through this before? Please help me. this is my 2nd E46 and my first diesel.

I think I have a problem similar, basically I felt something go while driving.

I had hardly no power although it still drives with no lights on the dash. The real difference is a very loud wirling hissing noise ??
