Just changed the cabin filter which was not as bad as I was expecting, but now have big problems! I assumed the connector shown in the picture came off the glove compartment I had to remove, but there is nowhere for it. I did not remove or disturb any of the connections to the fuse box. Looked extensively but could not find anywhere for it to connect to so assumed it must be an unused connector. Big mistake!
Tried to start the car:
Relay clicks but does not turn over.
All the red warning messages to the right of the speedo flashed
Messages:
Immobiliser failure, Anti-Skid Failure, brake failure, engine service required.
Tried again today:
Radio stopped producing any sound, then remote stopped working and lights stayed on so had to disconnect the battery.
I assume I have interupted the CAN network.
Anyone know where this connector should go!
I assume after that I am going to have to connect a diagnostiuc tool and reset the faults.

 

Turns out to be one of those worst case coincidences! It is a dodgy battery, which just happened to first manifest itself immediately after doing the pollen filter. As a warning to others, when the battery voltage drops you do not get the normal slow crank, all the ECU's go crazy and you get these multiple error messages making you think you have got serious problems!

Glad you got it sorted out
