Hi,

Not necessarily any ECU failure. Had same no-response situation in 940 with LH2.4. Engine had suddenly started to run very poorly. Turned out to be one of the injector connects that was half-loose. Either a response here on the board, or in the FAQs, mentioned that you can have a no-response due to oxidized leads, for example at the main board connector leads. I never dug into that, since my problem was easily fixed. Checked again 1.5 years later, still no OBD signals, car ran like a beauty.

IMHO I would check the main board connector for oxidation, maybe my problem was just one oxidised lead, maybe you have also a, for function, critical lead oxidised. Letīs hope for a simple explanation first, before fearing the worst.
