Vag-com
 

Can VAG-COM be used to set the dynamic pump timing on the d5252t in an 850tdi. My mechanic says he can't get it to work ? Can it only be done with vol-fcr ?

As far as I understand, it can only be done with Vol-fcr, as its specific to ecu etc.

it can only be done with VOLFCR, or any dealer or BOSCH.

Wot Mike & skye said ......................... Only Vol FCR can be used due to ECU Specific issues ..

But I do understand where your coming from as the D5252T IS a VAG engine But thats ALL IT IS "AN ENGINE" Everything else is Volvo Specific

Dealer use a VCT2000 right ?? BOSCH ?? Care to elaborate please ??

Spot on Keith, VAG's Engine, Volvo's ECU. Vol-FCR has to be a specific version, > 1.5 to do the timing IIRC ???

That explains why VAG-COM is not working then.

Basically my mechanics changed all the belts, but cannot do the dynamic timing as he doesent have the software. However the car runs and starts hot or cold perfectly fine, and drives normally, but apparently throws a fault code saying timing is out of spec once shes warmed up.

How much should I be looking at to have the timing set ??

Apparently Volvo want £160, a VAG indi (not sure if he will just have VAG-COM or BOSCH) wants around £120, reasonable ???

(P.S. just had belts, tensioners, rollers, cam seal (which involved sump gasket) and water pump done for just shy of £650).

if its MSA 15.7 then VCT 2000 will not read it,volvo should still have the old style code reader, if its MSA 15.8 then VCT will read it. BOSCH are diesel specialist and should have the equipment to read both.VOLFCR version 1.7.2 will do the pump timing for you the one you have said is the earlier version which will not , these are the crack copys that you get on the bay.

yes £120 is about reasonable they can be a pig to get right .

What is involved Mike ???

AFAIK vol-fcr will just tell me the degrees of the timing, if its out, how exactly is it adjusted to bring it within spec ???

Apparently the engine needs to be running, is this just to read the value, or to do the adjustment, or both or vice versa ???

Is it dooable for the DIY with basic mechanical skills or best left to the pros ??

, there are two tensioners on the belt, the bottom one is used for the adjustment. slacken of the nut but not too lose so that you can move the pulley backwards and forwards with the allen key in the slot, with the engine running and up to the test specs adjust the bottom pulley backwards or forwards and watch the pump timing degrees move on VOLFCR 1.7.2 when you have it to the correct setting switch off and then tighten the pulley nut.
it is do able without VOLFCR but it can take ages or not at all, its fine tuning the belt tension so that its within the peramiters that it should be, remember that if you try and do it without the test kit if you lose the setting the car may not start.

this is what it looks like
