Im not yet allowed to post on 406oc so im posting here to see if anyone can help.
My 406 is shit but the biggest anoyance is the warning lights and the fact that one of the faults is causing it to go in to limp mode.
The warning messages are
Engine Antipollution Fault
ABS Faulty
ESP/ASR Faulty
The limp mode is just massively under powered and wont let the engine past 3k. It wont even hold 70mph up a hill on the motorway (2250rpm) foot on the floor. It does sometimes come out of limp mode but goes back in if i get up to cruising speed and stay there for more than about 2 seconds.
Ive had the DPF removed and mapped out but its still throwing a fault about being unable to connect with the DPF ECU
It did have codes relating to dodgy boost readings and the map sensor so I have replaced this however on the dyno it still showed a dip in boost at about 2600rpm
It was showing that the rear abs sensors were dodgy and i replaced these and cleared the fualts but they came straight back without even driving the car saying open circuit and unable to communicate.
It is missing its ESP/ASR switch from the dashboard and I cannot find another to replace it with
