Has the new battery voltage dropped? & do you have a charging issue?. |

Yes these are spot on I'm an electrician and electrical engineer so it's not whats obvious but is clearly a low voltage issue or bad connection and as these are a crazy minefield was hoping someone might be able to narrow it down before I start throwing money at it. |

Those are all communication (or lack of!) based errors, have you tried disconnecting the battery, leaving well alone for ten minutes or so and reconnecting?

Yes battery off an hour and many crossed finger. But nothing and thus press pedal to start is newest before when thjs fault was present as soon as I pressed start with or without pedal it started which was odd as I was trying to put ignition on for OBD reader and it just started without pedal.

What Pheonix said, but before reconnecting, make sure ALL batteries are disconnected INCLUDING any auxilliary batteries, touch the two battery terminals firmly together for 5 minutes before reconnecting the batteries.

Just re-read the original post, I missed the point about the faults existing before the battery replacement.

Thanks I'm going to try the battery and system reset and I have a new brake switch as I saw these can be temperamental and for £12 got one ready. Any hints on how to get to the brake switch which panels to remove and how. |

Right, well you're getting somewhere then - check the ground connections and check that power is getting to the correct pins on the ABS connector - don't rely on 'if it's at the fuses, it will be at the module'.

can this be done with the module in place as it looks like any movement is going to to require removal of hydraulic lines its the 5.0 and the module is up under the wiper area on driver side same spot as battery but opposite side.

You should be able to remove the connector with the ABS in situ, then remove the outer shell to access the back of the connector - use decent backprobe pins, don't ever probe the connector faces - you'll just cause pin grip issues.
