Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that suspect a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suspected cause
I would suspect the instrument cluster rather than the temperature sensor, but as I suggested in the above thread, a diagnostic check might throw up what is wrong, and the Porsche tester can operate the gauge independently to test it.

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

Hi. The needle on my temp gauge has got a mind of its own. It doesnt reset towards and beyond the number 40 when you turn the ignition off. When you next turn on the ignition the needle is already reading around 80 so when the temp goes up it goes off the scale and eventually goes right round and hits the fuel gauge needle. Does anyone know if this can be repaired or if I can get a replacement set of clocks. The part number is 996 641 108 01 70C. Typ UK. VDO 110.008.722/012. Thanks.

Robert! I've only heard of this once before on the forum, but I don't know what the outcome was: https://www.porscheclubgb.com/forum/FindPost/776937 https://www.porscheclubgb.com/forum/FindPost/826787 I would suspect the instrument cluster rather than the temperature sensor, but as I suggested in the above thread, a diagnostic check might throw up what is wrong, and the Porsche tester can operate the gauge independently to test it. A used cluster might be your best bet, but you need to get exactly the same type (model year, transmission, coupe/cabrio, etc) and you will need to have the mileage corrected. A new cluster is over £2000+VAT, by the way...... [ ]
