Sad day Jim but fully understand it. Good luck with what ever you decide.

Fingers crossed thats sorted it mate. You will also have the comfort of knowing you now have spare dizzy, ecu, switches etc. if they ever go again.

Sorry to hear you aint sorted yet. Is the fuel pump priming on ignition, it should buzz/ prime before cranking? There is also a control box in passenger footwell behind lower left panel, can get water ingress leading to bad contacts, just a thought whilst you are checking electrics! Are you sure it doesn't have an after market immobiliser fitted? Any fault codes showing up on readers? Running out of ideas now though.

Search online 'VW Engine Management ECUs' site suggests Sharon Vr6 2.8 AAA is the same part number. Good luck with it.

Good question, honestly don't know. Need somebody with more knowledge than myself to clarify. UK are 2.9 but I would have thought any dizzy model would be ok. Mine is 021906958B. With a bit of luck the new ignition switch might cure it.

Ecu could well be the problem, however, I am surprised its still starting intermitently. It might be something as simple as the ignition switch. Cheap fix but fiddly job. I would be tempted to replace it for peace of mind!

Hi again. Stripping ecu showed obvious signs of burnout, severe discolouring. I was fortunate as I had a spare from a broken car in stock. You could pick up another ecu from a breaker. Is there an american equivalent of the forum? There is quite a lot of choice of beakers in the UK but shipping will put the cost up. Is it still intermittent or simply refusing to start now?

Good call, replacement dizzy will reassure hall sensor issue, but symptons were similar to my failed ecu. It stopped for seemingly no reason, refused to start again for some time then started as though no issue until stopping again. Replaced ecu and cured it. We stripped ecu to find signs of burnout.... must admit it had a super chip fitted in the ecu some time in the past which may have caused the problem!?

Hi, by block ground do you mean earth strap? That could be the issue. Guessing that if you have power to the coil then that rules out the common faulty ignition switch and probably the immobiliser? I have also had an ECU fail, so many possibilities. Good luck with it.

Hi, remove the dizzy and check the securing pin holding the locating block, which locks position onto the camshaft lugs, isn't slowly dislodging. I had it on mine to the extent of barely being able to remove the dizzy. If it drops out it falls into the timing chain… ouch. It was a reconditioned distributor and I guess they hadn't lactated the pin in place.

Mine is the same Jim, think they are inherently noisy engines. It is easy to listen too hard and perhaps become a bit paranoid about them, just drive it and enjoy it because they are an absolute pleasure.

Apologies but I am going to cry off the club stand, might go as a spectator to check out new show venue.

Alternator output, check battery voltage with and without engine running, should be reading approx 13.6v running. May be as simple as faulty connector on the alternator.

Oh dear, looks like I will be 'billy no mates' then. Hope the sun shines!

I failed to get early bird ticket, just wondering if the club stand got booked or is there a general lack of interest. Is anybody planning on making an appearance?
