a4 1.9 tdi problem

[The Photographer]

Can anyone help please ?
Audi A4, 1.9 tdi avant. year 2000.

intermittently loses power.
had new turbo, new MAF, New waste sensor ?? And another new MAF. Still got the same problem.
If I pull over, switch engine off, switch it back on again, problem clears (until next time )

Mine was a vacuum pump mate.
Only thing is there are £230
(Darkside developments sorted me out)

It couldn't hold pressure especially when going up a hill, plus my drive way was up a hill which made me realise what it was .

Only thing I can think of it get it on vcds and log a few runs until it drops power then that should pin point it.

It's either that, or injectors mate

Cheers, it's been on the computer about three times now and each time it comes up with something else, hence all the new parts. Last time after fitting second new MAF no faults were registered !!
