Hi, i've got a bit of a troublesome problem with my 2006 Berlingo 1.6 hdi.

The problem started about a week ago, when the engine gets warm and you go above 2500rpm the engine starts to splutter and cut out. At first when i took it to my mechanic he couldn't get a fault code. Then the next day on way home it spluttered to a halt and the engine light came on.

After sitting for a couple of mins, managed to get back to the garage on limp mode ( about 700yds at a time before it stopped again.

This time it threw up the fault code P1113 Fuel rail pressure sensor- low pressure

As it had a new fuel filter 8 weeks ago and suspecting a dodgy injector, as it had been leaking for a short while, the injectors were removed, tested ( 2 ended up being reconditioned) and refitted.

After that he put another new fuel filter on, just in case other one was faulty.

Still no luck so today he fitted a new fuel pressure regulator (i think thats what it's called)

No joy! He thinks there is air getting into the system, as he replaced a bit of the fuel pipe with a clear piece and after every engine run you can see some air come through the pipe when you bleed it with the hand primer pump.

It starts fine from cold and doesn't seem to show the problem until it gets warm, but i don't normally rev it too high when it's cold anyway.

We are both at our wits end, and me at the bottom of my wallet.

Please anyone, any ideas?

Thanks

Sorry, forgot to mention, today after a test run it threw in fault code P0087 on top of P1113
