My 2012 Megane 1.5 dci 110 is starting but cuts out after a few seconds. Check ignition system and check anti pollution system is on the dash but the only fault code is for an aircon sensor. Changed map sensor, cleaned egr valve, checked fuses and relays, new fuel filter. I just can't get to the bottom of it, any ideas? Any help would be much appreciated

Hi, Joem really sorry to hear this, managed to fix it? Given your situation and the actions you've already taken, it's possible that the issue might be related to the anti-pollution system error message rather than the aircon sensor fault. Consider checking the following:
1. Diesel Particulate Filter (DPF): If your DPF is clogged, it can trigger anti-pollution system warnings and cause the engine to cut out.
2. Fuel System: Further investigate the fuel system beyond just replacing the fuel filter. Issues with the fuel pump or injectors can cause these symptoms.
3.Wiring and Sensors: Since you have an unresolved aircon sensor code, ensure there isn't a broader issue with wiring or other sensors that might affect engine performance.
It may also be beneficial to get a professional diagnostic scan from a Renault specialist or a dealer who may have more advanced diagnostic tools that could pinpoint the problem more accurately.
