4 engines.
the diesel is:
A 2,0 liter l-R4 TDi 103 kW (140 PS)
Volkswagen-designed
diesel engine was available for the
European and
Australian markets, replaced in 2011 by the 2,2 liter
Mercedes-Benz OM651.
so posting with out stated the exact engine.
is not possible to answer.
to work on any cars engine, one most know what is there first
DO TELL ! please.
for engine issues, pretend the enigne is parked on a work bench
and the car is on the moon. gone.
then tell use what you have, its and engine, with engine/efi problems.
better yet, why not post the symptoms,
so we can work that and not have to explain, each part, out of context.
