Intermittent Rev Counter Problem

[RichieK]

I recently started experiencing a problem with the rev counter in my S1:

Occasionally if I hit a bump the rev counter dies - it can be brought back by tapping on top of the Stack

Assuming it was a loose connector I removed the Stack and reseated the connector - but still no joy

I'm pretty sure the problem is the connector, if I wiggle the connector it makes the rev counter drop out.

Any suggestions how I can fix it?

Give you good odds it's actually the cable on the sensor in the rear wheelarch. They fracture all the time. Must have fixed mine 4-5 times in the 10 years I had my S1...

If banging the stack fixes it then my money is on the needle being loose on the spindle. Nightmare fix! Ask MMC would be my advice

Thanks

I'll check the sensor wiring first.

Where about in the wheel arch / which side is it on?

...just had a quick google for images.

Is the sensor for the speedo? - does the rev counter not get its feed from the ECU?

The speedo work fine - it's just the rev counter that has a problem.

Sorry skim read - ignore me, yeah sensor is for speedo.

No worries - thanks anyway Shug

I think the needle is pretty solid - it seems ok when it does its re-set every start up, and it seems to read fine when it's working.

I'm at CLCM this afternoon for a geo setup so I might nip into MMC while i'm there. Whatever the problem is, it's probably past my DIY abilities anyway

Got it booked into MMC - I'll update the thread with their diagnosis
