EGR Valves

Hi All

Just thought I would post this as there are many threads that seem to fade out just when getting to the nitty gritty of the problem.

So here goes

Symptoms:

1. Renault scenic 1.5dci showing "check emissions" showing on dash intermittently but getting more frequent.

2. There appears to be a flat spot and power lacking on acceleration which by taking the throttle foot off and back on again overcomes the problem and get full power again.



FIX:

1. Took off EGR Valve and cleaned the chamber in which the egr valve fits. A piece of carbon about 3 cms long came out and several smaller bits. Cleaned valve and refitted. Now car won't accelerate at all (appears like I have not turbo)

2. So bought a new EGR Valve and fitted it. RESULT car "appears to have a new engine" - Can now hear the turbo coming in and out and mpg at 70mph = 55.9mpg. Acceleration is smooth again and the emissions light has gone off without needing a reset.



Job was fairly easy to do as long as you take off all the cowling around the lower windscreen area(including the wipers/wiper arms)

Hope this helps others if you have these symptoms as to what to do. Cost of job was £60 for the EGR Valve. Local Renault garage wanted to charge me £72 just to do a diagnostic check!
