Suspension, exhaust, electronics and campaigns on the Mondeo IVKnown weak points

Engine / equipment: Ford Mondeo IV (petrol and diesel)
Period mentioned: 2007–2014
Symptoms: Play in suspension and steering joints at the roadworthiness test, many exhaust defects and oil leaks; immobiliser (2007–2010), engine management (2007–2013), camshaft sensor, starter; on diesels, a clogged particulate filter (up to 2012), boost control and CAN bus (2012).
Possible cause described: Recalls: a control unit (several systems failing, fixed by software), the brake-servo check valve, the pressure plate (fire risk) and 2.2 TDCi injector O-rings that can leak fuel onto the hot engine.
Check for the garage: Check campaigns by VIN; check suspension, exhaust and leaks; on diesels, the particulate filter.

1.6 TDCi turbo starved of oilInjection / turbo

Engine / equipment: 1.6 TDCi (DV6)
Period mentioned: Approx. 2004–2018
Symptoms: Hissing from the engine, diesel smell in the cabin, very dark oil between changes and, eventually, a failing turbo with smoke and loss of power.
Possible cause described: The injectors’ copper washers stop sealing; the gases form carbon that gets into the oil and blocks the mesh filter in the turbo oil-feed pipe, starving the turbo. The wrong oil and switching off with the turbo very hot make it worse.
Check for the garage: Check the injector washers and the turbo oil-feed filter. If the turbo is replaced, also clean the sump, intercooler and feed pipe, or the new turbo can fail again. Use low-SAPS oil.
Cost cited in the source: Approx. €1,200–2,500 for a turbo replacement with oil-circuit cleaningA rough figure from the original database, not an up-to-date quote.
