Customer reports that engine started briefly then cut out.
Fault codes are
P0170 Mixture bank 1
P0130 upstream lambda sensor
P1653 phase variator
U1600 key invalid.
The amber key light stays on and the injection lamp goes out briefly and comes back on when the ignition is cycled.
I have measured the key reader coil at approx 3.3 Ohms. I have removed the immobiliser and checked for dry joints and power.I have had five diagnostic tools on it, Sykes ACR, Delphi, Solus, Multiscan and Launch. None of these offer comms with the immobiliser. Without any comms with the immobiliser it is going to be difficult to narrow this one down. Is there any aftermarket tool that is likely to talk to the immobiliser? Or is it so early it doesn't support diagnostics?
