Ghost in my Radio

[DABelectric]

Hello everyone,

I've done a search for any previous posts on this but cant find anything on it.

I bought my 58 plate Fiat Scudo Van a couple of years ago. But last year the radio started experiencing an intermittent fault by which the volume turned itself up until it reaches 'full blast'.

Over the last year the fault has gone from fairly intermittent to nearly every time I turn the radio on. It occurs when stationary so it's not really linked to any speed settings, in fact I have made the volume/speed setting inactive on the radio and it still happens.

It can turn the volume up quickly or slowly, there is not real pattern.

There is a control paddle on the steering wheel. No buttons seem to be stuck. I had a 'DIY' go at seeing if I could disconnect the paddle at the steering wheel end but I could not see how that could happen. I also don't know which wires are coming from the paddle and terminating at the back of the radio? (Which would be the easier way of separating the two) It may not be the paddle but if it can be temp disconnected, I guess it could rule out that over the fault being with the radio itself.

Just been looking at second hand replacements on ebay, I don't want to buy one if I don't have to (obviously) and the second hand ones need a codes!

Any advice/experience in this matter would be amazing.

Best wishes
Danny

It could be a software fault within the radio, which is probably not fixable. Or it could be a problem in the steering wheel remote controls.

The remote controls are probably on a separate plug into the back of the radio. Definitely will be if it is a Blaupunkt. You'll need to pull the radio out, and find the extra plug. Disconnect it. See if that 'cures' the problem. If it does, there is an issue in the steering controls, which might be a warning of problems looming with the clock spring. Like its name suggests, it is a coiled spring, with multi-tracks, taking the signals from all the steering controls including horn and airbag whilst allowing the wheel to rotate.

If disconnection does not fix the issue, it'll need a radio.

Thanks for your reply.

I've had the radio out previously and tried to pull the plug on the steering wheel remote. But the only separate plug to the main bunch did not do it.

I think I'll be trying a new radio.

Cheers
