A3 Tdi Instrument Panel Repair

[rfisher]

My temperature guage is dead.

I've had 2 thermostat and 1 sender replacements which made no difference.

I've read that this fault can be due to the instrument panel being naughty and for around £150 - £200 you can send the panel off to be fixed.

I'm pretty handy at most stuff including electronics so does anyone know if this is a capacitor or transistor fault that I can sort out myself.

Failing that, does anyone have a schematic of the panel that I can look at?

I have no idea on the physical repair but can vouch for Cluster Repairs UK for doing a good job at sensible money.

google for the gauges i know they are available seperately somewhere in the uk , just can t remember where . known fault on these cars

Are you saying that you only need to replace the gauge and not the entire panel?

The gauge is just a moving coil meter - the only thing that can go wrong with that would be a stiff bearing.

It's more likely that the problem is a degraded capacitor on the board causing a low transistor feed to the gauge.

Anyone got a schematic of the panel?

Is there one in the Haynes manual?

could sell you a set of clocks but you have to pair them to the ecu .mileage is zero

saying that i have a damaged set of tdi clocks from an 04 plate car.guages work fine one of buttons to adjust time /trip is snapped but these can be swapped . circuit board is in two parts back part contains immobiliser ,mileage data etc , which is missing eprom .
but front part with guages and full dis display is fine so is the front and surround .
