Renault Repair Questions? Ask a Mechanic for Answers ASAP
Ideally if yourself had a generic code reader to plug in..then that would give an insight as to what type of fault your maybe dealing with here..that could still be something to persue here and would have to be something your need to get done anyway to see what fault codes you have..to be able to progess forward towards a repair..the warning generally covers issues seen by the ecu regarding Air/fuel injection system and emissions...the most likely cause we see or the most common on these 1.9dci's is EGR related especially so if the cars isnt used all to often..the valave tends to stick due to excesive carbon soot build up..and thus causing power delivery issue or flags a code and puts the car into limp mode..the valves can be taken off and cleaned up..and should help..so worth looking into that if the fault codes point to that of course..the other is fuel filters can be an issue too ive seen..more so if they havent been replaced in a long time..so again definatly something to consider..but id say more based on experiance id say it possible egr issues..but again like i say get the car scanned first..all garages would do that anyway or should be doing before investigating..hope this helps
Yeah lack of use can be factor in alot of problems with modern deisels these days..i see a heck of alot..especially so with DPF's and EGR valves as the engine doesnt get enough running time to get upto the operating temp and help burn off that excess build up of soot..obviously its doesnt get rid of it all it. but small journeys doesnt help...so in that view alot of the time advice really if the car isnt in reduced power..is to add a higher premium diesel or diesel additive into the tank and then take it on a long hard run ona motorway in 4th for upto 10-20miles and that normally helps..But as advised above certainly get the car scanned first - see what codes you have - and then take it from there....
