P38 dhse no power but only in reverse?

What Data was saying is to check the amount of fuel that flow from the filter when the ignition is turned on i believe its 180ml in one minute.

Yes the sensor and the line to the manifold are new and I cleaned the outlet from the manifold with some brake cleaner and I've picked up a new bosch fuel filter this afternoon

I think you need to due a fuel flow test while you have the filter off. Bacterial growth in the fuel can cause blockages.

Are your intercooler/turbo pipes okay not internally delaminated?

Good shout on the turbo pipes when mine went it had no power and would stall if any throttle was used.

Only just realised what you were on about. Mixed my words up somewhere between my brain and fingers! Had no idea i had typed mass! Too much beer.

Lucky you J I'm jealous.

In a conversation with a 4x4 specialist the other day he said that if an autobox on a TD5 like mine breaks down in reverse, when you put it in forward, all the bust up sh!t goes into the rest of the gearbox and fu cks that up too.
Do not know if this is at all relevant but it may be of use to other TD5 drivers.
what use the info is, i am not certain.
Maybe if reverse goes t!ts up it would be a good idea to stop, take the box off and get it rebuilt. Might be cheaper if only the reverse bit needs fixing.
Hey I have only ever rebuilt manual boxes, so what do I know!!

180 Ml in ten seconds.

I'm really stuck on what to do now I do like the car but cant afford to keep chucking money at it and it not be fixed

You can take pipes off with a screwdriver and check they are not worn. Will cost nothing.

Fuel pump test also costs nothing. Can do both jobs yourself. All the knowledge is here and the people to talk you through it.

Not had chance to really have a proper look but the boost hoses do seem very soft and weak unless that's how they used to be before the likes of samco hoses ect ?

They should go hard when engine is revved. Check internal for any flappy bits.
I flushed intercooler same time

Total cost to me was about £2.50 in petrol to flush- biggest power gain from single job I’ve done on this vehicle.

Had a few more tonight. And last night. Missus has been away!

Think I may be on to somthing this atmos figure dont change but what does it relate to please

Manifold pressure from the MAP sensor. Engine stopped or MAP pipe removed it should read atmospheric pressure, roughly 14.6959 psi = 1 bar, engine idling the pressure will go down due to vacuum in the manifold, when the turbo is working the pressure will go up, gear in D, foot hard on the brake apply some throttle for a few seconds and the pressure should rise.
If there is no change, it could be the MAP sensor, blocked manifold spigot, waste gate stuck on the turbo, de-laminated or leaking pipes, even a seized turbo (unlikely).

Well it's not the map line or sensor as they have been replaced . So I need to look at my pipes intercooler and waste gate

Wouldnt have thought throttle pot would show 17% if on tickover, just a thought.

Sorry it wasn't on idle I was holding the pedal a bit to so the atmos pressure wasnt changing

This is on my list of stuff to do. How long did it take you to flush the ic?

Not big job to whip it out. I swilled it through one end into a bucket, then used same stuff through again and again, then final swill with fresh.
fill it up and bung the ends with an old t—shirt, leave soak overnight (will find leaks) is best. Some people use acetone.

I left it in sun all next day to thoroughly dry out - it must be properly dry before refitting !
