Sorry for the delay... think I've sorted it! Had a good going through the wiring under the drivers side of dash, all okay. Checking behind the fusebox I found a plug not quite seated correctly, think it was plug G1 or G2 (tricky to see behind in there). Since clicking it back in correctly (& making sure the rest are seated tight) it's been as good as gold... even feels better to drive. Thank you to everyone that contributed for your time and knowledge on this issue... Cheers guys.

Thanks for the response guys, much appreciated. The ECU is an AG as the car is a coilpack model but early 1994 one, so unfortunately it doesn't have the immobiliser box behind drivers side of dash or a reader coil - think it's part of the ecu circuit on AG pcb, which I visually inspected for damage. Fla, when I try restart the engine during fault it shows NO lights and does NOT crank, it stays totally dead - until the car decides it's time to play ball again, then it does everything as normal (dash lights, relays energise) and fires straight away instantly as if I've just imagined the whole cut out that's just happened. Dox, I've been through all the fuses as mentioned, checked them all with a multimeter just to be sure - all good. The alarm does have its own immobiliser (which I had wondered about) alarm functions perfectly when car is running, but also arms and disarms when car is in fault/dead mode - it could well be the immob' circuit in the alarm system unit has a dry joint or bad contact. Again, thanks guys.

Hoping that someone can help me, as this has got me completely baffled... 1994 Corrado VR6 intermittently cuts out for no apparent reason: No misfire, stutter or change in engine character before it cuts out - just an instant stall, dead. Fault can happen when car is sat idling or when it's being driven, more likely to occur when car has been running for more than minutes and warmed up. Car runs perfectly outside of this fault, it's just sailed through it's MOT, emissions readings are spot on - car behaved perfectly through it's test, but stalled on it's way there and on way back after. When it cuts out there are no dash lights illuminated: oil pressure, coolant, brake, ABS warning and ignition lights all stay off. Mileage and clock stay constantly on when fault happening and don't flash off or disappear/flicker as fault happens. Car can stays 'dead' for a few minutes, re-trying to start it does nothing - no dash lights illuminate and no sounds from any relays. Other times it re-starts straight away. Car has a Scorpion 1218T alarm, which still works perfectly throughout the fault - car will arm and un-arm as normal, locking all doors and illuminating the separate dash alarm LED. Arming and un-arming the alarm does not reset or clear the fault - car stays in dead state even after this procedure... until car decides it's time to start again. There are NO faults on VCDS when scanned (apart from the normal crank sensor G28 fault code '00513 03-00 no signal' when any VR6 engine is off, which clears and stays off once started). I've recently changed the ignition switch 6N0905865 twice (Meyle) & both the ecu relay 109 and fuel pump relay 167. Also been through all the fuses. No change. I removed and checked the cars ECU yesterday, to look for any damage or burns on the main PCB - all looks perfect. In the 19 years I've owned this Corrado (and 32 years of VW ownership) I've never had a fault I can't rectify... until now. Any help or advice would be most appreciated.

Rest of this gear is finishing this evening.

Two of these parts finish this evening.

A friend of mine's left the fold & started to have a clear out. There's a new/boxed brake pedal position sensor (now obselete) part number 357 927 810, A mint black A-post trim, induction kit, steering wheel and loads of 16V / VR6 badges...
