The National Highway Traffic Safety Administration is launching an investigation concerning 40,000 2011 Volkswagen Jetta TDI[/URL] models. This is the result of NHTSA receiving seven complaints from Jetta TDI owners citing leakage from the fuel line to the fuel injector. If an official recall is issued, both the 2011 Jetta TDI sedan and SportWagen will be affected.

NHTSA's report states that the common rail fuel system in the Jetta TDI operates at extremely high fuel injection pressure - up to 26,000 psi - and that the seven complaints involved vehicles that had between 2,470 to 7,764 miles on the odometer

Additionally, NHTSA says that it has received a similar complaint regarding a Volkswagen Golf TDI, which uses the same 2.0-liter diesel engine as the Jetta. The investigation was officially opened on August 2.2011 Volkswagen Jetta TDI being investigated over potential fuel leak originally appeared on Autoblog 5.0 on Mon, 08 Aug 2011

Yes, it's an easy fix. They replace the fuel line or rail. I've seen a few posts where it specifically mentions #2. I don't why #2 seems to have problems.

On the bright side, diesel has a high flash point so it's not as insanely dangerous as a gasoline leak (get the marshmallows) :panic:. But yes any fuel leak could ignite if subject to the hot parts like the exhaust manifold and pipes and any fuel system failures should be reported to the NTHSA.

You'll know, the fuel is under such high pressure that once it leaks the engine bay is soaked. The smallest pinhole leak = enough to notice. You'll smell it too.

In fact, if anyone removes their engine cover and finds wet fuel o-rings, please take a high resolution picture. It seems some people are getting just wet fuel rail o-ring seals instead of a full blown wet-t shirt contest.

This did happen to me. It was a relatively quick fix, one full day in the shop. I have no idea as to cost, but I am sure whatever is "quoted" is way more than VW(or any brand) actually pays for the parts and labor. It was noticeable, I saw some whiffs of smoke and when I stopped at a traffic light I could smell the diesel. Drove straight to the dealership and they took care of me pretty quickly. All the posts I read involved the #2 injector.

Okay, this brings an interesting point up for me. How do you remove the engine cover? It appears to just snap on/off. But I tried to apply some strength to it and I'm afraid of breaking the plastic.

The transmission dipstick is under the cover I was told and would like to be able to check fluid level once in a while. Why do vehicle manufacturers seem to think we're a bunch of dopes and can't be trusted to check these things without having to go to the dealer?
