My name is Dave and I am the proud owner of a 320d touring 51plate 2002, 125k
I have a problem with the power on my BMW, a month ago I was taking my wife to work and as the turbo kicked in there was a shudder (flutter what ever you want to call it) it was like a misfire on an old petrol car with a carb. I lost all boost for a split second but then all power came back, a week after I was travelling home from Skegness and as I went to overtake the same shudder happened again but this time the car went into limp mode. Not knowing anything about cars much I travelled home at 30mph (slower going up hills) when I got home I turned off the engine then restarted. My BMW was no longer in limp mode but now there is no power (Boost) at all and the car as dropped from 60mpg to about 45mpg. When the engine is cold I can sort of hear the turbo wine, when warm I cant really hear anything.
I unplugged the MAF and it drives (performs) exactly the same, very little or no boost. I cleaned the MAF (no joy) I got A new aftermarket MAF (no joy) I got a new genuine OEM MAF and still no joy. I cleaned the EGR and replaced the pipes the I could get to with new ones but the car is still very low or no power.
Any help would be really appreciated.
