Only happened twice but.....

Travelling along in my TD4, sudden lack of response from the throttle pedal but no spluttering and it was if someone had turned the key off.

After a few seconds normal power again.

Second time pulled out of t-junction and same happened again, foot flat on the floor and walking speed in 1st gear.

The garage have checked the pipe to the turbo solenoid and nothing appeared on a scan of the ecu for faults.

Any ideas?

Debris in the tank or fuel filter maby? take the fuel pump out and give it a clean.

Quite possible that your fuel pump might be on the way out.

sounds a bit like fuel pump to me, sooner or later it will happen more and more, the engine management light will come on

Thanks (as usual) guys!

Is this only at 70mph+ by any chance? If so, you might wanna give this thread a read, as it's a common problem:

I had this issue but it seems to have disappeared for now. No doubt it will return, like most landy problems...

Thanks Rich but it was about 55-60mph and 5mph the second time.

Will have a look at the thread anyway - its on my to do list lol!

If it has only happened once or twice then maybe it was a fuel blockage somewhere. Maybe give some redex or other additive a try just to give your fuel system a clean.

Could it be an injector issue?

Lowside fuel pump generally wont give you lack of power at 5mph, since it will generally rev freely until 3.5k rpm in neutral without lowside working. If fuel filter is blocked then i would say it would be a more common issue , although you might just be seeing the start of things. Easy way to check if your lowside pump is working is to put your hand on it, to see if you can feel it vibrating, although you'd need it to fault whilst stationary first.

Checking the pins on your high pressure fuel raid pressure sensor and tightening them up if you know how, is always 5 minutes well spent with loss of power on these TD4.

hope that helps some.

Thanks Vissie, no I don't know how to and any help would be most welcome

Cheers
