Hi all
I'm looking for some insight to help decision making how to approach a potentially expensive fuel system repair.
What can I expect for other known failures and costs associated with Tiguans between 200,000 & 250,000km's
What can I expect the diesel specialists to report and how do I read best their pending diagnosis?
Background.
Our much appreciated '09 Tiguan TDI has just ticked over 200,000km. We plan to replace in 2yrs when payments for the Focus RS are complete.
The Tig has fallen into a bout of expensive mechanical issues and is now slumped into the 3rd round of potentially expensive repairs.
Given the age, value and lost confidence of reliability (mainly of my wife) we are debating scenarios around continuing to repair, repairing and moving it on, or cutting our losses...subject to diagnosis & repair cost.
Details
Owned since new.
Manual.
Is clean and in good general condition.
Vehicle has been maintained correctly throughout, driven appropriately, meaning city driving mix with plenty of regular sustained highway work. Wife (her car) does a decent job. Not laboured, over revved, driven lightly when cold...tows a dirt bike trailer regularly.
Has an APR tune, for ever...otherwise engine is stock.
Brakes & dampers replaced & in good order.
Clutch is original. Expect to wear out within the next 2yrs, assume $2,000-2,500?
6mths ago A/C compressor -$2000
3mths EGR replacement and turbo bearings - $3200, believe should have been much more.
Last Friday it failed to restart after a hot park.
nearby non-VW, non-diesel mech had a first pass over it today.
Identified the fuel filter is contaminated with algae.
Tank is usually refilled between 5/8 & 3/4 empty.
Hasn't been run close to empty recently.
As a rule, we use brand fuel and target 'new' fuel stations.
He replaced the fuel filter and the engine now runs but with engine light and flashing glow plug light in limp mode.
Suspects risk of damage to high pressure fuel pump due to poor lubrication citing algae.
Mentioned a possible temporary fix (unfamiliar sch???) but I didn't understand the parts. He advised against.
I called our usual VW specialist (CVWC) who are unfortunately booked solid for 2 mths. They recommended a diesel specialist. I intend to follow that advice.
If the H/P fuel pump is damaged, I assume, say, >$4000??
Car is parked.
Insight appreciated.
