Hi All, over the past few weeks I have noticed a "rumbling" noise after start up, esp when its been cold outside. The Revs seem to be constant, and not bumping up and down, and putting it in and out of gear doesnt make a difference. The engine is not throwing a code
A little bit of throttle does make it disappear, and once the engine is warm its a lot less apparent, although it still appears if I idle too long at roundabout etc.
Any ideas? Its due a service, but I have a feeling that its not related to that. The noise was alot louder this morning than before.
I have a OBDII bluetooth scanner, so can get real time readouts of various sensors etc, if that would help a diagnosis
Thanks!
