Just wondering as I follow this page even tho I sold my tdi years ago
Why are people still holding on to them if VW is offering everybody a buyback option ? You know about this hpfp failure and the scam regarding the emission, who would want to keep this car now ?
Ok, I didn't even know about hpfp being a problem when they did the emissions fix. I kept mine because the amount of money I would have gotten for a 2010 jetta TDI was not enough to get into a new car. I figured that my car was going to keep running for 250k more miles before I'd ever have to get a new car. I got the fix when I was at 127k miles, and at 134k miles my fuel pump broke coming to an intersection.
They feel it won't happen to them...
Or they don't know about the problem with the hpfp..
When I bought my 2010 Jetta TDI (in 2010) I had no clue about problems with hpfp. However, I am just learning about it. Perhaps knowing they failed so often would have been a deciding factor in my purchase. I love the MPG I get, which is why I got it.
Make/Model:Volkswagen Jetta TDI
Diesel Fuel Source: Most of the time Smith's (Kroger) and occasionally Maverik (rare). my last 3 fillups were from a Smith's, and I actually have receipts from those.
Problem: One night, on June 6th, my car stalled coming to an intersection, glow plug sensor light flashed and car wouldn't start again. Towed to dealership, and they found metal in the fuel, and they discovered the fuel pump is broken. They're claiming my fuel won't pass the contamination test and won't honor the warranty that should be covered by the extended emissions warranty. I highly doubt their test, considering I was about four HUNDRED (400) miles into that tank of fuel when the car died.
Dealer: Ken Garff VW, Orem, UT
Status: The dealership claims the fuel is contaminated and believes I misfueled. I have receipts proving I filled with diesel. I also have a government agent (motor fuel specialist in the division of agriculture and foods) who talked to Smith's about possible contamination, they have had ZERO complaints about their diesel. This guy went to the dealership and collected some fuel from my vehicle. That test he is doing is currently pending, and I'm also working on getting a third-party to test my fuel. I find VW is being a brat about the entire situation. Dealership couldn't tell me what was in the fuel causing it to fail their "test". And I'm going to be so mad at them when my fuel comes back as having zero gasoline in it and they've had my car for over an entire month.
Anyway... I'll update this when I get more answers. This is something that should have been fixed when it happened because the HPFP is a known issue, and just the fact that I have physical receipts showing I used the Diesel pump, the gas station has had zero complaints, and that I was almost 400 miles in my tank of fuel when the car died, ALL POINT TO THE FUEL PUMP JUST BREAKING, not contaminated fuel.
EDIT: Got some results from the Dept. of Agriculture and Food. Here is the result (couple things blurred out like his name, my license plate number, and the dealership) https://i.imgur.com/YqxkHUu.jpg
He informed me about how the dealership performs their test, which is a density test (essentially a hydrometer) and so I don't know if those service techs know how to accurately perform one. It appears that the density test needs to be done with fuel that is around 15 degrees celsius (about 60 degrees farenheit) and I am sure they simply took it from the car that had been sitting outside for about 4-5 days to "test" it.
What do you take away from the results?
I've had some time to think about it. Here's my reaction.
The flash point is the only thing that "failed". I put that in quotes, because #2 diesel flash point minimum is typically 125ºF. This result put me at 115ºF. (And for those curious, winterized diesel flash point is 100ºF). After some researching, I discovered that if you had 1% of gasoline mixed into diesel, the flash point would lower by a whopping 64ºF!! The mere fact that my flash point was only 10º F less means that it's more likely due to the fact that it's not been stored very well. This sample was taken almost a MONTH after the car has been sitting outside in the summer heat on the dealership parking lot. I am pretty sure that would be a cause of flash point to be just slightly lower than it should be.
All of the other tests passing means there is more evidence proving that there was no gasoline contamination. The viscosity would likely have failed, the distillation would have failed, heck, even the density probably would have failed. They all passed perfectly. I'm calling BS on the dealerships "test".
