building an M-TDI pump

[anto]

[
Put the parts in the AAZ pump to make an M-TDI pump. So that way you won't need to worry about that part.

Sorry for the hijack but what exactly does this part do?
Or could someone point me in the direction of some info on this part?

At the moment on my peugeot i have it hooked to a constant 12v+ supply and the car seems to run fine but id like a bit of reassurance.

Thanks
Anton

No clue as that is on a regular TDI pump I believe.

 you must have the only peugeot that has one off theas valves . i have never seen one on a peugeot, thay only do idi or comen fuel rale, what i no off, and i have seen lots off peugeot diesels

that is the selenoid that controls dynamic advance on a tdi VP37 pump.

sorry to pull the topick but would be relavent if you were building a moded
tdi with fly by wire , i am not shure how to mod this  dynamic advance valve, but it must open a bit to alow more fuel to push agenst the timing piston , the ecu controls this valve , so maby a ristor in line may pull a bit more timing over the rev range , i may have this a bit wrong so just chime in and help out

Leave it unplugged and the pump run like a normal pump,  but this pump do not have mechanical load dependant, you have to drill it.

It came on 2 pumps i have, both came off a 1.9td 406.
The 406 unlike the 306 is semi ecu controlled, it uses a sensor in the no 2 injector i imagine to adjust the timing of that solenoid.

PS tintin - i originally left it unplugged on my pump but i could not get the timing set at all properly.
By twisting the pump both directions in their full range of motion i could not get that "sweet spot".
Only when i plugged this to a constant 12v+ could i get a sweet spot.
However i seem to lack top end pull, could this be the cause?

Some AAZ have this selenoid too (N108)

You have to change the pressure regulator for one from a pump without this selenoid if you leave it unplugged, and make pump housing modification to add the load dependant fonction.

[anto]

What exactly is the modification to pump housing to add the load dependant function?

[Tintin]

Unfortunately its too long to explain.

Take a selenoidized pump housing and compare it with 1.6TD pump housing, and you will see what is the difference, and reproduce it.
