So the wife's TDI sportwagen is headed back to the dealer...again. This is its third visit since the !!!error: Indecipherable SUB-paragraph formatting!!! .

!!! UNKNOWN CONTENT TYPE !!!

The second time was this Saturday, after I got it back (Friday) I drove it all day and put it through its paces. I went to go fill it up (still a 1/4 full) and noticed a whine that sounded like a fuel pump. I thought "hmm, that sucks, but so far it hasn't done anything wrong". On the way from the gas station to the house I gave a few hard pulls through 3rd and RIGHT before I got home I was pulling in 2nd at WOT and around 4000 rpm I get warning lights and my power goes bye bye. I limped home but full power felt like pulling a 5000 lbs trailer up hill with the cruiser.

Take it back, and they pull the code of "low fuel pressure". My wife also tells me "oh, I forgot to tell you I've been hearing this whine and sometimes its hard to start." Thanks Honey for letting me know. Anyway, they check it out and find...surprise...nothing.

I pick it back up, and the noise is gone. good I thought, maybe when they pulled the filter the second time they put it back together right. So, more hard pulls just to be sure and before long the whine returns. I pull it into the driveway, pop the hood and sure enough

The whine is back (ignore the clatter of the diesel and listen for the vibration/rattle). When I turned it off and then tried to restart, it took 2-3 times as long and felt like it wasn't getting enough fuel. Also, when I parked it in the garage it stunk up my whole garage with diesel fuel. My guess is the low pressure pump is just faulty. Its back in today, waiting to see what happens next.

It is the uber TDI, trying to get infinite fuel economy one piece at a time.

Sorry to hear about this again. Dealer is going to love seeing you again

At this point, I would be very well versed in my state's Lemon Laws if this were me.

its crossed my mind. Though at 4 years and 40,000 miles I'm not sure where I stand.

Sucks dude. Do you think this is more dealership incompetence, bad parts, or poor vw engineering?

At the very least, I would want to have the names and contact info of people within VW Corporate.

Good luck.

I think its more B and C than A, but these systems are so finicky that it could be a little A

Glad I bought a Mazda. I looked at TDI golfs but the diesel premium put them out of what I wanted to spend and I was concerned about reliability. I always heard good things about the TDI VWs but knew too many people who had gas VWs with issues and they were almost always electrical.

Sounds like the low-pressure pump. I had a BMW E30, and when the LP pump failed it would run just fine until the HP pump overheated and either tripped out or created bubbles in the fuel, causing poor running conditions. After 30 minutes, it was cool enough to run for an hour or two again.

That sounds exactly like whats happening. its a brand new pump BTW. So was the HPFP the reason that the low pressure pump was failing? I mean, if the high pressure pump is overheating for some reason and creating air bubbles, maybe thats the issue we should be focusing on.
