    I've got a document with all the relevant codes for engine-related stuff on your BKY John (assuming it's the car in your sig), but I can't offer it to you as it's paid-for copyright info. Happy to look up any though.

    17604 is the heater circuit of the pre-cat lambda probe, the other one is to do with the aircon control unit having a logged fault (but sort of just says 'go scan that module' rather than anything specific).
    What are the other 3?

    the other three are the usual 00532 Low batt voltage ( Winter )

    16804 Bank2 oxy
    16686 Cyl 2 misfire

    Looks like I have wrenched the wiring for the pre-cat lambda or itself has failed/is failing ?

    Thanks

    Not sure quite what to suggest, check fuse 9 in the cabin, as that may be powering heaters in both lambdas, but I'd expect a more specific heater circuit code for lambda 2 if that were blown, I think.
    Info suggests checking the fuel injectors for the misfire code, you could try moving cyl 2 one and see if you get a change in the code with it in a different place.

    Great minds etc.etc,
    Now I've calmed down will try the logical approach and swap the injectors/ignitors/plugs from cylinder2 to cylinders 1,3 and 4 , making note of which to where and report back...

    Thanks

    Get a good battery in it first, a dodgy battery can cause all manner of dodgy codes.
