Other Faults on This Variant
DPF Blockage from Idling and Short Trips
ModerateFleet Transit Customs spend long periods idling at low speed — the worst possible operating profile for a DPF. Blockage is the number one reported fault across UK fleets.
EGR Valve and Cooler Failure
ModerateEGR failure on the Transit Custom 2.0 TDCi is extremely common in fleet use. The valve carbons up rapidly in stop-start environments.
Dual Mass Flywheel Failure
ModerateThe Transit Custom carries loads and covers high mileages — both conditions that accelerate DMF wear. A shuddering, rattling van at idle is the typical presentation.
