406 XUD questions - ginge191 - 30-11-2012
Been looking around at getting a new lump for the new year and come across a decent 406, bosch pumped etc.
Question; the semi-ECU controlled advancing system on the fuel pumps; how can this be removed/overwritten?
and also, just to confirm, these blocks were the DHX lumps similarly to the modern Xantia XUD's? with the coated pistons etc?
Have i got this right?
much love x

Replace the pump with a normal Bosch.

I thought it was only the DHYs that had the coating on the pistons.

I didn't know if it was easier to remove the semi-ECU system? than having to cam/time everything again

hmm? I just assumed it was on the newer 406/Xantia's ? Mix of information from a seller and online bits..

Ideal!
Thanks for that info; as for the fuel pump advancing issue? anyway to overcome this?

Rip off new Bosch and replace with old style one.
RE: 406 XUD questions - Ricky - 30-11-2012
Yeah the only way to do it is swap the pump. It's really easy to do it while the engine is out anyway.
RE: 406 XUD questions - ginge191 - 30-11-2012
i suppose; i could give it a go, not too difficult.

timing is the same I believe...still a pin in the pump wheel.
I have a bosch pump for sale

pm me
RE: 406 XUD questions - Ricky - 30-11-2012
To be honest if you're getting a new lump then it makes sense to change the belt etc anyway, I've just fitted a dhx myself and swapped the pump for a proper one.

Done
RE: 406 XUD questions - ally406 - 30-11-2012
Hmmmm tell me about these coated pistons? The only annoyance about the pump on mine is that it's armoured and I can't adjust the main fuel screw :/ Otherwise business as usual.
RE: 406 XUD questions - Piggy - 01-12-2012
They are all "armoured" with anti touch me cover...good pair of pliers or grips and hey presto!!
RE: 406 XUD questions - Kwik - 03-12-2012
iirc the semi ecu pump goes further then the non ecu pump
RE: 406 XUD questions - ginge191 - 03-12-2012
Spoke to Ruan about this and it's a pita to try and compute a semi ECU pump; easier to just put a normal Bosch on
RE: 406 XUD questions - Piggy - 03-12-2012
yup....
I think I know someone who has one
