you must have an aftermarket radio, disconnect it and it'll work perfectly

Little late to the party but for any future readers: If you need to disconnect the radio to get a connection, or if the radio turns on by itself when the car is parked and shut off, it's likely the radio's PCB has some corrosion on it. Scrub the PCB with some alcohol. You might find some black spots on the connections on the board.

Regarding the OBD connection: this could very well be the ECU. I couldn't connect with OBD for years, then the car died. Opened up the ECU and there was water damage (see imgur link below). Cleaned the whole board and properly sealed the ECU. It's actually easier than one might imagine.

The car never ran better and OBD never fails to read it anymore =).

Spaulding! Many thanks for the reply yes ECU is on the agenda once my neighbour obliges
I will report back once we have checked ECU
