I have an issue I'm trying to resolve but search as I might through the forum, I can't find too much regarding fault code p0087 on a 407, 1.6 HDi
I'll explain what happens and how this fault came about: (or scroll to the
' ***************
*************** '
to skip the explanation - though it may give clues?)
I am traveling around 600 miles a week, 2 x 250 mile runs - non stop motorway + shop trips, 30 mile trips here and there etc.
3 weeks ago I decided to go get an oil change. upon the change the mechanic came to me and said the oil was in a bad way, super thick, like syrup.. I saw it myself - he suggested an engine flush. This was done, then new fully synth oil 5 -30w
Next i'm on my 250 mile run journey, the engine light came on and power was retarded to 3k rpm only.
I continued the journey as on the motorway, eventually the car cut out, engine died and I had to roll over to the hard shoulder. I didn't have pp2k with me so I was a bit in the dark, I tried to restart the car a few times without luck - I waited 15 minutes or so, then tried again. it roared into life and it would rev higher than 3K rpm, though the engine light was on.
This occurred twice on this journey, limp mode, then cutting out roughly 20 minutes later.
The journey back was ok, though I drove slower to make sure I made it home - the engine light was illuminated the whole time, I never pushed the car beyond 55mph. it was a long tedious journey....
Once back I plugged in PP2K and took a look at the issues...
p1351 - preheating relay circuit
p0490 - Electric EGR valve positon copy signal
p1462 - Electric EGR valve position copy signal
p0409 - Electric EGR valve position copy signal
This seemed relatively straight forward then, I assume the DPF is blocked - I forced a regen, the process completed but PP2k said there was an error once it had finished.... helpful.
I came to the conclusion I needed some DPF fluid topping up, & to remove the DPF and give it a clean-out with a power hose and special liquid you soak it in for 8 hours. Whilst doing the work I also planned to clean out the EGR valve.
I stripped the cars air intake off, decide to change the air filter too as it hadn't been done for a while.
I removed the EGR valve and cleaned all the gunk and crap inside, it was bad! not awful, but bad, though the valve seemed to have relatively good movement. I went as far is completely stripping the whole unit down to ensure I cleaned absolutely everything, it went back on looking almost new and moving very, very well.
Next the DPF came off. I cleaned it all out following a guide from this site, I even went as far as to follow the guide in drilling a few holes in the damned thing to help prevent a possible blockage incident again.
I then went to top up the DPF fluid but to my surprise, once getting to the tank I notice it's completely full... from when I topped it up to the top last year - turns out hardly any is used anyway ( I imagined buying a litre of eyols fluid was probably not enough... glad i didn't opt for 5 litres of it!! haha)
Car all reassembled, faults deleted, everything checked with actuator tests & all looking good and driving good.
a week comes around, I've done around 40 miles since all the work, no more engine light, I head back down south on the 250 mile journey, the car engine light comes on after an hour or so, though I hit traffic and it came on when I started to pull away. Now the car can't rev higher than 3k rpm... sure enough, 20 minutes later or so on the motorway the car cuts out... fortunately I have my laptop with me just in case
(funny enough I was able to roll off the motorway, up the slip road, around the roundabout,thank you traffic lights! then into a services, and just about made it into a parking space by rolling with a heavy to turn steering wheel... I was chuffed
)

pp2K came back the following faults:
p1351 - preheating relay circuit
p0087 - Fuel high pressure regulation
So this is what i'm dealing with now.
I have consequently gone back over everything I moved last time to check everything was tight and where it should be.
The only thing I touched relating to the fuel line was the fuel filter, which I un - clipped from the holding bracket, removed the sensor connectors and bent the whole fuel filter backwards behind the engine block and out the way (fuel hoses still attached) so I could have clear access to the EGR.
I'm seriously scratching my head on this one and hoping someone might be able to give me some pointers or ideas.
