Hi, I'm new here.
Seem to have an issue with my BMW - E46 Touring 320D - 2003
Just had a smiple service at a stupid garage!!
It came back with very low power so I took it back again and they said that the vacuum hose had come loose...they sorted this out and most of the power returned.
I now seem to get black smoke when I accelerate and I haven't got all the power back.
It's worst when I'm on the motorway (70+ MPH)...any ideas anyone?
