Ford transit fails static regen

Post by djautos »

64 plate transit minibus 2.2
This vehicle has adblue (large cat) and dpf
Came into me for failed emissions 0.9 should be lower than 0.5
Carried out full scan no faults found. Carried out terra Clean dropped to 0.84
Felt vehicle was under powered and knowing the person who did look after bus asked to see if ecu had been mapped. So updated ecu to latest software and hey presto dash was like a Christmas tree. Took dpf of to find it hadn’t been knocked out. So sent to be cleaned, refitted dpf and emissions dropped to 0.79. Found cat had been knocked out in miss diagnosis of cat and dpf, also damaging nox sensor. Fitted new cat and sensor and took for a run about 40 miles. Elm came back on for adblue heater, fitted new heater and road tested again. No codes at all in any module. Flushed engine and changed oil and filter, carried out intake clean and got emissions down to 0.64 checking dpf back pressure and on WOT I’m getting 180 mbar so I wanted to carry out a static regen. I am using ids and as soon as I set it going if fails instantly I have done tonnes of transits and when they fail it at least starts and fails after 5 minutes this is failing instantly. Vapouriser good . I’ve even miti vac dpf pressure sensor to let it think it blocked until light came on and still fails. Anyone any ideas. Thanks
