Engine fault warning light- P0087

[Matt cla]

cr170 went it limp mode earlier on today. Ran some checks on the fault codes and it came up as P0087 which is low fuel pressure.

Since turning the car off and on again it has been fine, but I can see it popping up again soon.

I am thinking that it could be down to a dirty/blocked fuel filter.

Has anyone had any experience with this fault?

Cheers.

id change the filter first

 

[Matt cla]

Yeah that's what I'm thinking. Pretty straight forward to change the filter but without vcds I don't know how I'd pump the diesel back in before starting it up.

fill the filter housing with fresh diesel and hold the revs up after you start it. It won't cause any damage.

 

[Matt cla]

Cheers mj, that makes sense. Car has been fine since so I'm not sure whether to get it sorted asap or wait a month for service.

After a couple of days driving fine I've run in to a bigger problem now.

Engine light on again with EGR malfunction code p0403.

Car won't start. It turns over fine but then just stalls. Pressing the gas pedal just speeds the stall up. It is seemingly dead until the egr can be looked at.

Either massively clogged up (which you'd hope not at 45k), or something worse.

It's currently dead in the car park at work

Hi Just Got this Fault Code on my Seat Leon Cr170 2010 p0087 after lending the car to a mate. He put petrol into the tank and my car is diesel. Now the fault code is not going away and also dpf light has come on. Can wrong fuel cause this fault code or is it something else? Als any reccommendations as there is a loss of power.

I'm getting this code but haven't put wrong fuel in, cr 170bhp 2010 did you get to the bottom of it at all?

check/change the diesel filter. They can get gel'd up in cold weather.

Already changed it still getting code and going into limp mode when I put my foot down

Did you check the fuel filter for signs of metal debris?

Cos the CR170 occasionally eats it's fuel pump, and injectors.

As said above could be HPFP

Already changed the hpfp as it failed on me last year had it all cleaned out with second hand injectors, could the injectors be failing again?

Could be, although imo it's much more likely to be the pump with that code.

I've got a mobile mechanic coming to have a look to see if he can find the problem on the 13th will check back in when he's been cheers

It's very difficult to properly clean out the injection system after the fuel pump explodes.

The swarf gets all over the place, could easily have been in the fuel tank or diesel cooler.

 

[Steeley G]

Hi all sorry i havent been back on to say if the problem was fixed, unfortunatly i had to cancel the mobile mechanic as my little lad got rushed in to hospital. But i did change the fuel filter and so far so good.

 

[Steeley G]

Got the code back again unfortunately, so I'm going to get a new in tank fuel pump to see if that solves the problem would I need to code a new fuel pump in or will it be ok?
