I'd love to think that.

The initial problem was a dip in idle every 10 secs, so anything that remotely looks like an association in that way gets new parts. And that's all that can be done until the part is changed because vagcom shows no faults and testing parts only conclude in working ones.

Check everything anyway.

So when something sneaky like the ignition transformer works then won't then its only down to testing wits, so the only thing left to change after this is the ecu/immo then its a no brained. That's why I asked about them so I could replace parts from the last source, eliminating from there, but information is slow.

Last on list_ fuel pressure sensor_ after this is replaced the ECU will be the suspect. Before overhauling the ecu needed connecting to the immo, is this a warning of breakdown??

Fuel pressure sebsor? Wtf? You mean the fuel pressure regulator?

I've now got spark but it sparks when the ignition is turned to ON ;obviously a spark when starting/turning the engine (which doesn't yet I think because of a timeing issue). I have footage of a strong spark, on an exposed plug, when ignition is flicked on.
    What relationship is the error from, concerning the ecu? That's related to...earths?
Thats not normal or I would have thought possible! ....a current right through the dizzy and everything!?. I had just changed the EARTHED? ignition transformer/coil (another double named item, manuals and part names similarly sensor/regulator have listings from them Undecided) and it fixed the no spark issue,new rotor/cap/coil/hall sender/ignition switch/vacume leads/cleaned idle regulator/air intake filter box.. etc ,but does that mean it was responsible or broken by it, thus caused by the ecu?

I'd think of that before another parts required, but the next suspect IS the ecu. Checking that requires a tool but I don't have/get the intermediate one. Have vagcom. Is there other tests I can look to do?

HELP

 Grin I now have ignition and lift off.
The idle control sensor (or CSV or isv ..somthin) is creating a very rough idle, but the van works well without it.

I'm not sure of what the electrical environment is in a van is but the replaced components rely on electric current and are associated to the starting of it. The parts still show a working property yet, won't ENTIRELY work properly, not detected with safeguards so I assumed mechanical or ECU which confused me because there was sparking plugs from ignition ON not run. .. !? How can the ecu pass that on.
    So it was prime suspect until the icv made a lumpy engine.

REPLACED ignition, ignition switch, ignition transformer, rotor & cap, distributor hall sender, spark plugs and because leads were OK the electrical components are suspected of being the victims of electrical mismanagment , can the ecu be held responsible for killing them?

I think its an old battery that quickly gets flat...wrong voltage

Unless you can help.

...............................................................next day..............................

....it never ends..vagcom fault code 00532 supply voltage b+ 0700 signal too low...the connections to ecu need checking or battery on its way out.

I've returned to adaption and remet the immo to the ecu, again.

Is there some reason this needs that much attention. Why can't it remember it?.
Also traced no current from hall sender/distributor which are new. Is this likelily from an ecu related 'cant think' thing or immo. I guess its blown up from volts or earth yeah!?

Well thats about it, if there's no give or take on that its off to the shop.
Thanks anyway.

Can the relay/fuse no30 cause this much havoc.
