Hello,

Have you ever had the fuel pressure checked, if possible on that engine?

Cheers

Before you go too far with this, I would recommend that the question is asked in the Freelander section before the AG gang gets hold of it.

Hi everyone,

This is my first post so sorry if I have done something wrong.

I have a 2006 freelander sport 2.0d auto.

Normally the car is fine it has done 121,000 miles and regularly serviced.

Recently the power in the car has been lacking massively, as I drive down the road the engine can splutter and sometimes stall. The engine can take upto a minute to start with or without throttle pedal depressions, and there is abit of black smoke from exhaust along with a hunting idle.

So far I have done the following:
Installed a blanked EGR valve and cleaned surrounding components- very little difference made
Cleaned the crankcase breather filter - no difference.
Replaced fuel filter - no difference
cleaned maf sensor - no difference
Replaced fuel rail pressure sensor - no difference.

When I had diagnostics on the car the only fault code found was fuel rail pressure sensor error - fuel rail pressure sensor voltage low.

I can hear the fuel pump next to the fuel filter working and I'm confident it is not that however if feels like a fuel delivery problem.

Does anyone know of any common fault or think of something I have missed?

Finally I have one more question, with the maf sensor disconnected car runs exactly the same. However I thought this was weird so I compared to my 225+bhp golf gttdi and this is the same. It may be a stupid question but how come the maf/map sensors make no difference? are the engines ECU's compensating and running the engine and if so if an engine runs the same without them then why do we need them?

Thans=ks for you comments in advance!

I have to say I sincerely fail to understand why people don't scroll down to see if there's any more appropriate section to post in but I do get a steady stream of questions that are answered by ' have you tried scrolling down?'

Anyway....I hope you get the answers you need.

Oh the dangers of posting in the wrong part of the forum.

There's an o'ring in the high pressure fuel pump that fails and causes your problem.
Have a search on here, there's loads of threads about it.

As for the MAF, it runs a default map if you unplug it.

Hope you haven't been put off, just remember to post in the Freelander forum in future.

Make your first post into the anything goes forum is suicide.

I wonder if we'll see him again?
