Hi,
I'm look for any advice and guidance on an issue I have with my 2009 Passat 2.0 TDI-CR, 140PS - mileage 129,000
About 8 weeks ago on longish journey the car dropped into limp mode with the flashing glow plug warning. When I restarted the fault light disappeared and car drove as normal.
I read the fault code and it was 01027 pointing to an EGR issue. Took off the EGR and anti-shudder valve and cleaned both - neither was especially gunged up.
On a recent long motorway trip I had about 5 or 6 occasions of it going to limp mode but on each occasion it cleared when the ignition was turned off.
Decided to change the EGR and replaced it with a Valeo part (700424) and expected that to resolve the issue.
Long trip yesterday (circa 200 miles) same fault occurred but only once - same fault code and cleared with ignition cycle.
The fault does not seem to happen on short journeys so may be related to higher engine revs, equally I don't think its related to acceleration but I could be wrong.
Any thoughts on what to look at next?
I realise this is probably not related but the emission fix software update has been done.
