Hi all BMW-fans,
My car (525d ´04 manual) have the last month had a problem. When the car is hot I have noticed that the accelaration is uneven. When you slowly accelerate in fore instance 2 gear and you hit around 2600-2800 RPM the car stops to accelrate smoothly and it feels like the the car is reluclent to accelerate.. There is no problem with cold engine or hot when you accelerate more hard!
Any ideas? LMM?
All inputs are welcome!

Had the car in the shop.. No errors logged and the car pulled really fine. 194 ps and 434nm instead of 177 ps and 400 nm and off course the problem wasn't present that day :thumbsdown: So I will see how it goes the next weeks or so!

My Ride: 525d, on a 55 plate, 17" upgrade, big sunroof, removable tow bar.
My 525d manual also does this if i use tesco diesel. Sometimes does it with Texaco too. If i use Sainsbury's or Shell or BP or Callow (local) it seems fine.
So, take note of the fuel and see if there is a similar pattern?
