A Bit Of Help Needed On An Audi A3 Vreg '8L' Please

This is driving me nuts basically.

 

I plugged it in to vagcom and no faults showed up apart from temp sensor live short...

 

The list of faults are all clock related

-temp gauge goes straight to 120'c when you turn the car on and it comes up as overheating. Which is isn't. HG isn't gone.

 

-fuel gauge has always had a mind of its own.

 

- now the Rev counter and speedo have been playing real silly buggers recently

 

 

 

 

That's with the key out of the ignition.

 

Today I've

 

- redone all the earths in the engine bay

-cleaned up the positive bar thing on the battery

- put a new coolant temp sensor in today, hasn't fixed the 120'c issue.

 

Now other option is a new set of clocks, but I've heard rumours you have to reprogram them etc is that Bulls*it or true?

Have you checked the battery, sounds silly but a knackered battery can cause a load of problems. The immobiliser is built into the instrument panel, I found this out after removing the instrument panel to be sent away for repair from an Audi TT and it not starting with it out.

Battery is a good shout. A few years back the instruments in my Xsara went haywire immediately before the battery died. Worth a try.

 

I thought there was a known issue with Audi TT instrument binnacle a failing in some way? Could this be a similar thing?

Pretty sure it's not battery related, I put the one out of my 306 in there, still the same

I'll give it another go and let it settle in with a drive maybe

You do have to reprogram new clocks. The girl friends 1.8T has the leaky pixels and I read up on it. £100 to send the cluster off to get repaired.

A friend had a TT with a similar issue along with the clocks drawing the battery.

 

Pretty sure he sent if away to be fixed, I think it was these guys.
