Sensors under the manifold correctly attached.
Cam timing correct.
Injectors and seals OK.
That silly electrical lead at the back of the engine (cam position sensor?) OK.
3 metres of the little turbo hoses (including turboplus hoses) replaced and OK
Various vacuum hoses off the inlet manifold OK
Throttle position sensor OK
Lambda sensor was horrible but has been changed and was not a cure.
Crankcase breather hose is a twin-layer hose (a layer of plastic and one of rubber) and one layer is iffy but surely one layer remaining will suffice and anyway it wouldn't cause the manifested fault. Would it?
Plugs checked and OK.
HT leads checked and OK.

I'm going to buy a spray can of AMM cleaner (if it foxes the AMM well a pattern AMM is not that dear).

Garage knows a bloke wot has a load of 90s adaptors for OBD (and with any luck he will know if he can't read the Volvo not-quite-OBD) and will ask him to try to read the socket.

Failing which - and failing any other ideas - I'm going to build the Volvo code reader.

Incidentally, the fault is not significantly different from when I drove the car into the garage, so whatever it is is something that would NOT normally be changed when doing head gasket (and clutch).

I don't suppose overheating could kill the EZK could it? (and anyway the engine did not get hot enough to seize so I wouldn't REALLY call that serious overheating). It is the EZK I need to be thinking about isn't it?
