I have tried doing a search and have found some info related to my problem, but nothing thats exactly the same, not that I can find anyway. I was hoping someone my shed some light on the issue I have with my Laguna III 2.0 Dci M9R engine.
About 5 months ago the car was driving fine until one day it lost all power and went into limp mode, there as a loud wooshing noise from under the bonnet. When I got home I noticed that the big plastic intercooler air pipe had complety split apart on one of the joints. The engine light came on, along with the messages "check injection system" and "check anti-pollution system" and when I checked the error code stored on the
it had P0235 - Turbocharger Boost Sensor 'A' Circuit Malfunction.
it was due its service and since it was the 1st service since I had bought the car, i booked it into Renault. I explained the situation and said that I could save lots of money if I fitted the new intoercooler pipe myself as it was just a clip at each end, so thats what I did. Anyway car had it service and it was still going into limp mode, Renault told me this was because of the MAP needed replacing hence "Check injection system" message. Again I said i'll buy the part myself and replace it to save money.
I repalced the
, nice and easy and the "check injection system" message cleared and car drove normal again
But the "check anti pollution system" message is still on and so is error code P0235 - Turbocharger Boost Sensor 'A' Circuit Malfunction, but the car drives fine, no hesitation, not lumpy, not under powered, no strange noises. I can cleaer these mssages and errors using my OBD reader, but after about 2 days they come back one when I start up the car, but dont come on when Im driving.
any ideas on what I could do apart from takiung it to Renault and getting them to run theor Clip on it...
