Question 1

DPF blockage from short journeys (1.6 TDI)

Accepted Answer

The diesel particulate filter on the 1.6 TDI needs regular sustained runs at motorway speeds to regenerate. Cars used mainly for short urban trips light up the DPF warning, lose power and may go into limp mode; repeated interrupted regenerations also dilute the engine oil with diesel.

Question 2

Side effects of the EA189 emissions fix (1.6 TDI)

Accepted Answer

Engines caught up in the EA189 'dieselgate' scandal received a software update (and a flow transformer on the 1.6 TDI). Some owners report poorer economy, rough running, more frequent DPF regenerations and EGR or injector faults after the fix.
