2009 PUMA 2.4 limp mode

Postby thE Ear » 02 Dec 2021 08:21

Hi gents

Need assistance if anybody had this issue with a puma.
Fault reading: P0089 fuel pressure regulator. Connection is good. Vehicle will run fine unless the revs drop too low or if I stop at idle. Engine check light will reappear and back to limp. Can clear fault and she good again until revs are reduced.

Could the FPR be at fualt?

Thx

@theear glad to see you online again!

Sure sounds like the FPR - maybe if you can get your hands on a different vehicle and swap them to find out? I don't think I've replaced one, so not sure how much they cost.

But before you do that, check your filter and fuel pickup - the FPR will also throw an error if it is not getting enough fuel out of the tank. It might be a good idea to drop the tank and inspect the fuel pickup, it could be clogged by gunk.

I found this on Defender2.net, very useful info: https://www.defender2.net/forum/topic496.html

Hello Naks

Yes its been a while. Old TD5 doesnt give me any issues any more :)
The puma is a work vehicle so getting to know her now.

Thanks for the reply. Very useful. Will start with ordering replacement valve. Not many defenders around here to swap out.

I dropped the tank a few weeks back when the issue 1st started - loads of gunk and jelly like build up in the tank. Cleaned out and replaced the filter too. But now this intermittent fault keeps messing me around.

Thanks again for the help.

Cheers

Aha!

In 2008 we had a similar issue in our old Audi A3 TDi after a tank of bad diesel. Audi cleaned the tank and replaced all fuel lines under the service plan, but the car still didn't run properly and limped around. Audi said they did all the could, but I knew this was not good enough.

I then chatted to my landy mech, who told me to throw in a bottle of Wynns Diesel Cleaner. Whatdayaknow, a few kms after doing this, the car came alive again, and ran super smoothly, even better than when it came off the showroom floor.

So now I use this in all my vehicles on a regular basis, and it might be worth for you to try this as it might clear out all the gunk that is still in the fuel lines, etc.

My mech now uses this Bosch stuff which he swears by, even keeps a sample of water-contaminated diesel in the workshop to show clients how good it is.

It is certainly a cheaper solution to try.
