Last year my X3 had a new cylinder head gasket fitted, few months later the turbo went. The car ironically was just 3 weeks out of warranty when this happened. BMW paid half the cost of the new Turbo but not the labour, result £1k out of pocket. Yesterday the car lost power again..... Douglas Park BMW dealer in Glasgow have now informed me the EDR was blocked and the engine needs a decoke and inturn has damaged the new Turbo. Surely this should not happen so soon after having all this work done by the same dealer. Car serviced at regular intervals. I am at a loss here. Can any expert out there please advise on this. Much appreciated.
