Hi there peeps,
The Missus' Signum 1.9 CDTi 8v has recently developed a problem where after a short time of driving the EML (car & spanner) comes on and the car goes into 'limp home' mode and doesn't allow the engine to rev any higher than 2000rpm... turning the engine off and on again seems to clear the problem for a short while but it does return soon after
After checking the manual it refers to needing to drain water from the diesel fuel filter in order to cure the problem.
Firstly I've no idea how to do this or if this is even the actual cause (any help, advice, pictures etc would be a great help here ) but after reading numerous threads on this site about people experiencing similar symptoms with their cars I'm becoming more convinced that it could be a clogged up EGR valve...
I've looked at the sticky thread on here about the 16v engine version with great interest and will look to tackle mine soon, but I wondered if anyone could post up some pics or a guide on where to find/how to clean the EGR valve on the 8v engine.
For info the Signum is a 2006/55 plate with 100k miles. Its been fully serviced at a main dealers throughout its life, but given the mileage it wouldn't surprise me if the EGR was a little sooted up.
Any help would be greatly appreciated
