Re: 159 JTDM 1.9 Get Your Engine Checked
New to this forum, but can offer some advice that comes from a BMW owning friend (06 X3 2.0L D 15 days off road this year and dealer has no clue) , and a lot of research on the matter
Driving for economy with carbon recycling filters and traps is a no-no, they don't get hot enough and the engine management does not seem to know how to cope. Big miles, hot engines and lots of rev's would appear to be the answer
Cheap fuel may also be a contributory factor, but then what do I know, I drive a Volvo....
