Had a quick look at this earlier, when i got in the car this afternoon after it had stood overnight and switched the ignition on the rev counter needle reset itself to the proper zero position, I then ran the car for a few minutes and it was fine then started to creep around the gauge again.

Thanks for the quick responses, I'd intended to use my odb reader to check the actual revs I forgot you can use the HVAC controls I've used them to monitor temperature before.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

https://imgur.com/gallery/XFxOy Been out today for about 2 hours when my rev counter started behaving erratically. I noticed it was sticking when dropping revs then instead of sweeping forward and back smoothly it started to behave like the second hand on a watch slowly ticking round the dial, this has continued and it is now operating erratically between the 6k section and where the speed is displayed below the dial as shown in the picture Has anyone seen this before or have any ideas? The car is running fine still. Chris

POST 2Original post

Do this and have a look at the digital 'true' rev reading: http://911uk.com/viewtopic.php?t=81945

POST 3Original post

That's the first time I've seen that, hopefully someone has had it happen before and knows a cure. At a guess I would guess the needle is loose on the dial or the dial isn't reading the impulse of the sensors correctly.

POST 4Original post

Yeah that. The true digital reading on the HVAC will tell you if it's sensor or dial issue.

POST 6 / ORIGINAL POSTEROriginal post

Thanks for the quick responses, I'd intended to use my odb reader to check the actual revs I forgot you can use the HVAC controls I've used them to monitor temperature before. I'm not sure it is a loose needle although I'd be happy for it to be I suspect something's broken down on the PCB or ribbon cable and replacement units are not cheap at all, wonder if I could swap a boxster tachometer in plenty of those for more sensible money. Typically I'm using it for my wedding this weekend. Cheers Chris

POST 7Original post

I might be wrong but before you jump of a bridge :sad: I am sure there is a stepper motor behind the speedo and rev dial certainly in golf's MK3 1997 an erratic or unresponsive dial this is something to check in VW's it isnt a big deal to replace,you just have to get the stepper motor, if it is a bit more terminal I would always ask BBAreman. I know it is porsche but I have resoldered together my dash in my golf due to dry joints and it was straightforward good luck

POST 8 / ORIGINAL POSTEROriginal post

Had a quick look at this earlier, when i got in the car this afternoon after it had stood overnight and switched the ignition on the rev counter needle reset itself to the proper zero position, I then ran the car for a few minutes and it was fine then started to creep around the gauge again. I connected my obd code reader and monitoring the rpm the car sits at the correct idle but the odb read out is also jerky when pressing the throttle which I don't think is right, I'll check it's response to swmbo's mini at some point for comparison at some point as I haven't used it for awhile. How does a 996 get it's rpm information, is there a rpm sensor or is it just taken ofd the crankshaft sensor signal?
