Electrical gremlins - indicator/headlight flash

Post by thomasbrown92 »

Hi folks - hope you're all keeping safe and well!

Been suffering with some electrical gremlins over last couple of months. Originally it seemed to be quite sporadic and the symptoms were under normal engine load, the ignition would momentarily cut out as if stalling for a split second, but come straight back to life. Last winter, I had some mice nesting in the crevices of the intake manifold, so am worried there could be some nibbled wiring at play!

After the car had been away for a number of weeks being seen to for a separate issue (though I did reference this intermittent problem) I was driving the car home (25 miles) and noticed that this problem was happening more frequently, but also when I was using indicators or flashing headlights to let people in/out (call me knight of the road...) not on every use, but this is when the problem was becoming apparent.

I sat with the car running on the drive and the main headlight and hazard light functions seem to be unaffected, so by layman's diagnosis I seem to have narrowed down to the wiring/switching behind the left-hand steering column stalk.

Has anybody experienced anything similar?

Anybody know how to check this wiring or how to get to the steering column?

Thanks a lot in advance!

I had cutting out issues as described on my Z4, it was a loose negative battery connection.
