Ford Transit Custom 2.2 TDCi DPF fault — high soot load
DPF warning light on the Ford Transit Custom 2.2 TDCi. Commercial vans doing predominantly urban delivery routes accumulate soot rapidly as the DPF rarely reaches regeneration temperature. A minimum of 20 minutes at motorway speed weekly prevents rapid blockage. A professional forced regeneration clears the fault when the DPF is blocked. Fitting an auxiliary pre-heating element to the DPF can help commercial operators who cannot avoid urban routes.
