Ah right, thanks, ok today I decided to remove the (hopefully faulty) antenna from the steering column. The two part shroud/cowl came away with a bit of wriggling (a slight turn of the steering wheel revealed the two final screws) at last, I could see the antenna. There was a screw at the top securIng the antenna ring to the ignition barrel but it was very difficult to undo, then I noticed a small plastic tab holding the indicator lever assembly to the column, once it was pulled off the antenna was easy to remove. I disconnected the multi plug and cleaned the terminals, just in case that was the problem, but no difference. i wanted to take the old unit to the dealer to check it matched the new one but the blue coloured cables from the assembly could not be detached easily from the column, so I decided to pick up the new part at this point anyway. The replacement part only has two wires attached which should make the job simple, (so no need to remove the blue cable from the column anyway) now back at the car, the two ‘simple to fit’ wires turn out to be anything but, or rather, removing the old wires from the multiplug is very tricky, I fiddled about with tiny screwdrivers and paper clips but they refuse to come out easily, it was cold, raining and getting dark so I have left it for another day. Any tips on getting these connectors out? At least the doors still lock with the remote so hopefully that is a good sign.
