Hi All, hoping for a little help please. My 53 plate Cmax tdci, went into Limp mode last week. Ive taken it to a garage who put it on the diagnostics machine and it came up with a P0047 fault - turbo/supercharger boost control solenoid circuit low. The guy has replaced the turbo boost solenoid but the problem still persists and when back on the diagnostics machine it is still saying a P0047 fault and the car is still in limp mode. He has taken it to another garage to put on their machine and that is saying the same problem.
It is booked in at a expert diagnostics company on thursday but the initial fee is £70 before they even start looking further into the engine. Before it gets there I would like to see if anyone has any ideas what else this problem could be.
There is no oil leak or smoke coming from the exhaust (except the normal smoke from a diesel), no unusual noise coming from the engine either.
Any ideas anyone????
