hi,
my 940 2L turbo has started doing the same with the light (I disconnect the battery too). I wondered whether its because my head gasket went (in the process of replacing) and additives in the antifreeze have contaminated the sensor. When I've slapped it back together, I'f it's still doing it I'll cheek the outputs as outlined in the FAQ.
That was awkward to get to with the cylinder head and the manifold removed! I removed it to get the bottom manifold nut

regards
pierso
