FAP problem with 1.9dCi Grande Scenic
Another FAP problem with a 2007 1.9dCi Grande Scenic. “Regenerate FAP” initially came on whilst abroad in mountainous country so unable to regenerate before it “locked out” and “check injection” and “service” lights came on. Travelled 2,000 miles home without any apparent effect on performance or fuel consumption. Reset by Renault dealer and all seemed OK, he suggested that when the FAP lights up there would be 10 starts before it is “locked out”.
After a further 3,000 miles the FAP light came on. As I was going to do a long run over the weekend I made sure the car was only started 5 times, the 6th start on the morning of the run resulted in a lockout and the check injection, etc.
My questions are:-
1) Is there a definite number of starts before the FAP locks out?
2) Is the number of starts variable in the programming of the ECU?
3) Once the FAP has locked out presumably high speed motoring will not regenerate it as I believe the ECU should pump in extra fuel to hit the required temperatures in the exhaust.
Comments very much appreciated. Car has 50,000 miles under its belt.
By the way fuel consumption is about 48mpg on long runs and 43 as an average including local runs. Possibly driving to achieve a reasonable fuel consumption aggravates the FAP build up!
