Hi, can anyone help?? I recently bought a 2001 1.9TD ELX 105 JTD which required a new turbo. One was duly fitted but the car remained in limp mode with high revs. The fault code P0236 Boost Valve Pressure appeared. My mechanic spoke to Fiat who advised a new MAF sensor, this was duly replaced but the car still remained in limp mode with high revs. The mechanic then followed ALL of the advice given previously on this forum with regards to code clearance but the problem remains. He then transported the car to Fiat for diagnosis and incredibly they said they had no idea what the problem was but it MAY be a faulty ECU, faulty map sensor or faulty turbo.... :bang: My ex seems to feel the problem may lie with the MAP sensor. We fitted fiat part no. 46468682 (Bosch 0 281 002 215) which was a direct replacement of the one previously fitted but could possibly have been the wrong part in the first place!! Before I spend any more money on this car I would appreciate some advice on where to go next. It transpires there are TWO Map sensors which fit this car - The one currently fitted and Fiat part no. 46811235 (Bosch 0 281 002 510 or 552) The difference appears to be that one is a 186AXE1A and one is a 186AXB1A can anyone advise what the difference is in part terms. I can find no information about which of these relates to my car. Also would it be beneficial to get the ECU checked? The mileage on the car is only 61,000 and Fiat suggest this is a common fault, if I do need to go down this route I would really appreciate recommendations on reputable companies.
Many thanks in anticipation of help
