2009 TDI Code P0087

Hi there everyone,

I rarely post on the site but I'm always reading up on the TDI's and recent issues....

I would appreciate help with what has happened to my 2009 Jetta TDI.

I was driving to work and at idle my engine shut off and the onboard computer on the dash said engine failure shutdown. I cranked it several times and it just would not start. I took it to a reputable VW/Audi specialist and he plugged it in to VCDS and it stated P0087 - fuel pressure low.

He replaced the fuel pump underneath the rear seats and the fuel filter. Took it for a ride, ran great called me and i picked it up. Within 10 mins, the glow plug light came on and the buzzer stating car needs to be serviced. Turned around and within 5 mins the car died (im assuming its a safety feature????). Regardless, car would crank but would not start.... I am awaiting an answer tomorrow, but i have also read some scary stuff.

I'm wondering if it is possible that the fuel pump itself (the new one) is just broken or is there something more serious?

Anyone with any info or who experienced something similar would be great to hear.

Thanks everyone!!!!!!!!!!

There are actually 3 fuel pumps in your car. Apparently it is not the one they replaced that failed. Let's hope it is not the dreaded HPFP failure (which it could be). The first thing to do is to remove the fuel metering valve from the top of the HPFP (2 torx screws) and look at the bottom of it. There is a screen, see if that screen (and the bottom of the hole) is full of little metal shavings. If it is, your HPFP has self destructed and the only safe repair is to replace your entire fuel system from the fuel tank to the injectors (including that new fuel pump you just put in). If this is the case, see a VW dealer. So far Volkswagen of America has been paying for the repairs when the HPFP self-destructs, even on cars out of warranty. It can't hurt to try.

Have Fun!

Darn it, sorry to hear!!I'm not far from you and can offer help if you need.

Thanks!!

Thanks guys.... my car is still standing in the shop today and my mechanic ordered a new pump; well see where it leads us too. I have called him and given him some of the advice you guys offered and he said no metal shavings (which kinda put a smile on my face) but hes still waiting for the new pump. Ill keep you guys posted.

Oh, I didn't realize that Richmond Hill was in Canada. VW of Canada has not been paying for all HPFP repairs, so ignore the part of my advice that says take it to a VW dealer. 2micron just might be a very valuable asset in your repair process. He knows far more about the fuel systems in our cars than anybody at a VW dealer and probably more than 99.99% of all the people who work for VW. You might want to meet Andrew and let him see your car (since he is apparently close).

Have Fun!

Sorry to hear about your issue Polpg27

I would ask your mechanic to take the fuel metering valve off the top of the pump, like mentioned above if its full of metal shavings prepare for big expense

If its not that great sign however the HPFP might still be dead (mine died without contaminating the rest of the fuel system)

Yes be sure to contact Andrew (2Micron)

Hey guys just an update. My mechanic has spoken to 2Micron but I also called him today and he said he took apart the HPFP and confirmed no metal shavings or any sort of debris in the pump and as well as in the oil filter. The car still does not want to start..... has anyone ever heard of this or has any other suggestions.

Both electric fuel pumps can be run manually using VCDS. You could start by making sure both of them are pumping fuel. You could also use VCDS to monitor fuel rail pressure, as you try to start the engine, to see if you are even getting high fuel pressure to the injectors. A certain fuel pressure is required in the fuel rail for the injectors to work properly. There has been at least one case reported here of an HPFP failing but not self-destructing and there has been at last one case of that fuel metering valve failing. Unfortunately, these 2 failures could have been the same problem because VW does not have a part number for that metering valve - their solution is to replace the pump. Somewhere here (on TDIClub) is a post about a guy who found the Bosch p/n for that valve and purchased one from somewhere in Europe. Good Luck!

Anyway, the first thing you (or your mechanic) has to do is to make sure that fuel is getting into the cylinders. Once you know you are getting fuel, you can start to think about why it is not igniting.

Have Fun!

My mechanic has tested the HPFP through the computer as required (he even spoke to 2Micron and a VW rep) and they both confirmed he is doing it right. The pump is pushing some 400 pressure and it only needs some 350 to help the car start.... meaning its doing well.

2Micron (Andrew) spoke with my mechanic and they have ruled the HPFP out as the culprit, but perhaps the valve meter on top is broken..... Still the car shows no faults, has power, cranks but no start. Has anyone experienced this?

So I got my car back yesterday, finally. turns out it was the internal valve inside the HPFP that was stuck. The spring managed to get stuck. So my mechanic went on to clean and fix the spring (without replacing the HPFP), everything was reset and the car started immediately! He drove it for two days prior to giving it back to me and it works very well, like nothing ever happened.

A big thanks goes out to 2Micron who helped supply some testing parts and my mechanic for saving me a ton of money by playing with the pump without replacing it.

If anyone would like some advice or a good/honest mechanic, Call Vitali @ 905-771-6556 (this is in Thornhill, ON Canada - for those wondering).

Anyone else who has a good mechanic, before running to VW and spending a ton (unless you covered by warranty) try having your mechanic thoroughly investigate and play with the pump before replacing it and other components. At times, according to my mechanic, something small may be the culprit and VW decided to change the entire pump/fuel system because ``its there way``

Anyways, thanks to everyone for their help provided and feedback.

cheers

Lets hear it for 2 Micron and your mechanic!
It is guys like this who work on the "edge" that give us the information to keep these CRD TDIs running.
I have 2 micron's solution for the filters and it is a great mental comfort for me and my HPFP.
I am waiting to hear about a good upgrade kit for the pump as well if someone comes up with the final solution.
At 217,000 miles these things give me comfort and more confidence that I can afford to go on towards 1/2 million miles.

Thanks again!
