Volkswagen TDI Fuel Pump Warranty Extension ~ Episode 79

Volkswagen TDI Fuel Pump Warranty Extension ~ Audio Podcast Episode 79

Today we are going in depth on the warranty extension for common rail high pressure fuel pumps HPFP. This is a new extension that will cover certain Volkswagen TDI engines including:TDI Fuel System Failure

  • 2009-2012 Volkswagen  Golf
  • 2009-2012 Volkswagen  Jetta
  • 2009-2012 Volkswagen  Jetta Sportwagen
  • 2009-2012 Volkswagen  Touareg
  • 2012 Volkswagen Passat

To find out if your VW is covered under this warranty extension, call your local dealer and give them your V.I.N. they can look that up for you. Failure of these pumps has been happening since about 2011. One of the bad things about HPFP failures is the cost of repair. The entire fuel system is replaced when metal from the pump is pushed into the fuel system.

Join me today as we discuss:

  • Terms of the warranty extension terms
  • What vehicles are included in the HPFP warranty extension
  • The very strict criteria for HPFP warranty extension coverage
  • Fuel samples under the HPFP warranty extension
  • Modified cars under the HPFP warranty extension
  • What happens when a TDI is filled with GAS.
  • More pictures of HPFP failures
  • and more

    Just wondering if, in your opinion, you think they will (or not) cover if you have modifications that are not fuel-related, such as a DPF delete. Typically that would be combined with updated [performance] engine software, so that could also be a factor.

      Typically VW will not decline a warranty extension for a know problem. Example Injector warranty or intake manifold warranty on a modified CCTA would not be declined. As a dealer, I would have no way of knowing if your tune caused those parts to fail. That being said, don’t be stupid with mods. On the HPFP in particular, dealers are instructed to ensure the fuel guard (20T8) and stickers are present (20R9) and not tampered with. If you have removed your mis-fuel guard, you will have to pay to have it reinstalled. We are also supposed to send a fuel sample in to an independent company for testing PRIOR to repairs. They are not paying for Mia-fuels anymore. They’ve promised a 3-5 day turn around in results. The good thing is we no longer need a technical assistance case to get the pumps released to the dealers.

    In the forums there is some add-ons that will save the system for those that are outside of the warrantee. I think you should talk to Andrew and do a review of his parts if he is willing to send you a set to test out. I will be installing them this month. You do not have to post this but I would like you to take a look at it. His website is

    I have a 2011 Golf TDI with 122k miles on it. Received the warranty extension letter, will VW cover my HPFP since it went over 2k miles? I always use Chevron diesel.

      I doubt it. Generally when a warranty is extended, they offer no assistance after the extension. Kinda stinks but they have to put some kind of limit on it.

    Been dealing with a stop engine light going on and off for 20K. One mechanic said it was the fuel pump spewing metal; a VW dealer confirmed it. Now its getting fuel testing. I’ll let you know if they cover it (definitely no fueling with gas — duh!) Thanks for spreading the word on this… my theory is that we will see another bunch of failures as these age.

    Thanks for this article. I drive a 2010 Jetta Sportwagen TDi. The check engine light came on and it was a fuel sensor. For the first time ever, I took it to a local VW repair shop, not the dealer. After closer inspection they found a very rusty fuel filter, fuel filter canister and some of the lines as well. They have replaced most everything, stating they thought the HPFP was showing enough pressure. Turns out it wasn’t, and now that will be replaced. The bill keeps going up, but I feel I may have shot myself in the foot here, since it’s not a dealer repairing it (although the shop is using parts from a local VW dealer). Anyway, do you think I have any recourse with VW USA? I’m saving all the parts. Car has 57K miles on it. I’m the original owner. All warranty fuel work – the labels and constrictor in the fuel guard were added. Thanks, Joe

    Thank you for this detailed explanation. I have a 2010 Tdi SW with approx 70km. No problems to date other than a crappy AC. I had the condenser replaced last year. I have never lent my car out and have always used diesel from commercial pumps in CA and OR. This morning my car shuddered, lost acceleration and flashed the glow plug light on the dash. I immediately pulled over and had it towed to one of my local dealers (not where I bought my car). The service rep said that they were sending a fuel sample out for analysis to determine if I qualify for the system to be replaced. I am worried this dealer won’t go to bat for me since I have not taken it there for services. I have taken it to another local dealer for services for 10k thru 50k but based on my last experience at the other dealer, I took it to another in the area. Will that make a difference?Additionally, I had the 60k service completed at an independent service center. Do you think people like me have a chance at getting the warranty repairs? Any advice is appreciated. Again, thank you so much for this post!!!

      Your fuel sample is being sent to a 3rd part lab, and they will either pass or fail the sample based on specifications VW defines. I’ve only seen 1 failed fuel sample out of the many warranty claims I’ve done against these pumps. Dealers don’t have an option to either accept or decline warranty work, if it is a legitimate warranty claim, we are required by our dealer agreements with VW to fix the cars.

    I have 128000 on my Jetta TDI. I have experienced a high pressure fuel pump catastrophic failure and Volkswagen told me that since I am eight thousand miles over my warranty too bad they will not help me in any way shape matter or form do you have any suggestions?

    John says:

    Not that it makes any difference probably but I failed to mention we own for Volkswagen and they all have been serviced at the dealership as required. Not only scheduled maintenance but all maintenance and repairs have been performed at the Volkswagen dealership

    Hi. I am adding this post for record. I have a 2012 TDI Jetta Sportwagen, 71K. Tuesday, the glow light and check engine line came on. I ended up towing it to the place I bought the car (they got huffy about me not using them for every repair — as if I were a cheating spouse). They said the pump shows metal fragments and that they are sending the fuel out to be tested because it could be contaminated fuel. I sent my insurance agent to the dealer, called two gas stations that I use, and collected samples. I am wondering if anyone has had their fuel come back from the lab and deemed “contaminated?”

    Too bad VW only covered up to 2012 models. Have a 2103 Jetta TDI with 70,000 miles and suffered a catastrophic fuel pump failure. Doesn’t seem right but out of options as VW declined (twice) to cover the repairs. Ironically the cost to repair is within dollars of what my compensation will be for the TDI scam.

    2014 TDI – I had an injector error in April, but after their worked on the injectors I got a straight-out Fuel Pump CEL code. They moaned and complained about bad fuel but said the test sample they sent passed fine. I suspected they intentionally ran the pump with air while working on the injectors to get a huge repair out of VW, so I went to a different dealer just after thanksgiving when the car wouldn’t start unless you pumped the accelerator pedal and cranked for a while. This second dealer again treated me like an idiot, blaming misfueling, when I made no mistakes. But this time, while my buyback decision hangs out there, the lab says they saw “free water” in the fuel sample and denied any repairs. The dealer doesn’t even fully know why it won’t start, but VW has denied any repair to make it operational. Bureau of Weights and measures tested fuel station and found the station to be pristine and water free. I want to know where they took the sample from. Also, first issue occurred about 6 months after I switched to a job where I park outside – is water getting in my tank when it freaking rains?

      I didn’t post the followup story…I checked with our other dealer, back and forth from VW and they totally abandoned me with a $16k bill of exhaust, fuel system, injectors, etc..the works. VW was actually pretty harsh and pushed back on me to leave them alone. Now everyone I know and influence has sold or avoided VW completely.

      Early 2017, I ordered all three fuel pumps and a couple filters, flushed all of the lines, hand washed it all with soap and water, blew the whole thing out with air, replaced all three fuel pumps (takes a while on the engine one), and then primed the system with 12v to the tank and intermediate pumps. $800 in parts overall. Tricky, maybe, but the whole thing was actually pleasant to work on. And I didn’t disturb the injectors. It still didn’t want to start right away, but after a few tries it was running purely awesome. I shut it off, let it sit until my sell-back and drove it in and got my money. The end.
