Radio Interference

[topdown]

Had Comand for a couple of years and have just notice some interference - HT spark plug related maybe just one plug- increases with RPM.

Is this one or more of the coil / leads failing or is there an earth problem with the aerial?

Any checks I can carry out or is it off to to the stealer for some wallet emptying?

Thanks

depending on what car it is,there is software upgrades to erradicate problems like this,especially on 203 and 211 models

It is a W208. The interference comes and goes.

Is it coming on all sources, or just radio ?
