Thanks Doc. At the moment I am in lockdown, both national and family, so don't need any cars. The Omega, with extended MOT, is running well, the Vectra estate seems good, daughter's Astra and Jonny's Astra are both runing well. However daughter-in-law's Rover Streetwise failed to start this morning, so she went to hospital in Ben's Astra, and Ben and Tom walked here.
I drove to Ben's place, jump started the Streetwise, checked the voltage, engine running - 14.4 volts - , so drove it home, changed the battery, and returned it.
Then Ben mentioned that the ABS light on his 2006 Astra 1.6 manual was on intermittently. Probably ECU, I told him, but could be split sensor ring or wheel sensor. Will code reader tell me? Will the ECU on my donor 2004 Astra 1.6 manual fit?
I might need that Vectra yet. Goodness knows when I can get a spare coolant pipe.
