Re: Renault Laguna 2 - 1.9dCi No Turbo Boost/Limp Mode*FIXED*

OK, I've finally got my 1.9 DCi sorted with this problem.

It was the MAP sensor , but it was complicated by broken wiring from the throttle pedal to the ECU . The wiring was showing both heat and chaffing damage, leading to intermittent faults and loss of throttle response.

The throttle pedal had to be completely rewired back to the ECU . That sorted the anomalous error warnings and then the new MAP sensor stopped the limp mode injector warning light issues.

However, to add insult to injury, and no small cost too, the clutch and flywheel had to be changed as well.

I now have a very expensive 10 year old Laguna that is running well.
