Hi, I recently bought a Multipla 2001 1.9TD ELX 105 JTD. It required a new turbo which has been replaced, but ever since it has a problem with overboosting. The first mechanic was unable to locate the problem after blanking the EGR, replacing the turbo boose pressure valve and replacing both the MAF and the MAP sensors. The second mechanic thinks it is a wiring problem or an ECU problem due to no vaccum to the turbo actuator. The car is not in limp mode but goes into overboost at 3000 revs. Also, the brand new battery has been drained of power. Everyone in the forum seems to be pretty clued up on these things, can anyone please advise which route I should take next as they both seem rather pricey
Any thoughts at all are most welcome.
Many thanks
