can anyone advise please, I recently bought a 2005 2.0 TDCi ghia estate,
on starting it ran a bit lumpy but picked up on increasing the revs.
Had it serviced fuel , oil, and air filter all changed and ran fine
Two days later went from Derbyshire to London and after half an hour I noticed frost light on and saw a bit of black smoke , due to heavy rain and spray was not too noticeable, It was only when the engine was under pressure on an uphill gradient I saw the black smoke and it started losing power so that I had to keep changing down , ridiculous on the motorway,
Engine cut out on Clacket lane services and would not start , AA man arrived and changed the EGR valve which was absolutely clogged up, started after a while but smoked, had a piggyback home, Got the car started but now have blue smoke,
any advice most welcome, reading on this forum members suggest split boost pipe sorry this request is a bit long winded

regards

Rammer
