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


Sorry I missed the fact you have fitted a new EGR !

Have you checked the wiring under the wiring covers? I recently had a problem that after months I eventually traced to the wiring to the electrical connection under the vacuum chamber.
The wires at the plug looked fine, but when I stripped the protective cover back, the outer sheath of the cables was missing in places and what was there was crumbling away. The cables were shorting and effectively turning the turbo off by removing the vacuum to the wastegate. This maybe the case with your cables going to the EGR valve, as that particular part of the wiring loom is exposed to alot of heat from the inlet manifold ant turbo etc causing the breakdown of the cable sheath over time.

Hopefully this helps!
