WATER TEMP AND OIL GAUGE NOT WORKING - A6

[A6 trouble]

Hi All,

Both my Water temp and Oil gauge are not working on the instrument panel of my Audi A6 (2001). They both packed up together although under long journeys (with temperature) they show a small sign of registering low readings.

I have read many forums that indicate the Instrument Panel may need replacing but would this be the case if two gauges went at the same time?

Many thanks

Hi, I've moved your post to the correct area, should get a better response here

On the subject the instrument panel, they can be tempramental on most of the VW audi range. But there are other causes.

The best plan first would be to get the fault codes read for the instrument cluster as this would help allot.

The Water temperature sender is very tempermental, but i don't ever recall seeing a complaint about the oil gauge. the fuel one does play up more.

There are a few companies who refurb the cluster, or you can get one from the dealer, but I've seen quotes for £400+

Let us know how you get on.

Many thanks Rob,

I was hoping and preying for a quick cheap fix. Looks like a main dealer may be my only option.

Hi I also have an A6 2.0 SE (2001) that has suffered similar fate in the last week. Neither the oil or coolant temp gauges are working. The coolant gauge will move with some speedy driving but still does not reach 'normal working' mark.

Was wondering if you had managed to resolve your problem?

Hi again. It appearsyour problem might be with the thermostat apparently this is not uncommon with 2000/2002 year A6's. I took mine to an independent VW Audi garage in Dorking who were extremely helpful and a darn site cheaper than main dealer!..still cost £280. They replaced both the thermostat, housing and sensor. Since then both guages are working fine. Hope this helps

Hi,
I've just seen this thread, having posted a similar question about Oil/Water gauges on my 1997 A4.

Did you have any luck?

cheers, Zulu.

Hi Took to independent Audi garage Tutts in Dorking. Transpired it was something to with the thermostat and temp sensor. Cost me about £200 to have it repaired. Andy

Hi,
I have recently purchased an AUDI 2.5 TDI SE AVANT year 2001,
I noted the coolant temperature was very low, around 60~70°C, the temperature does increase when travelling at higher speeds on the motorway, this would indicate that the element is faulty. Does anyone know where the thermostat is located, it is certainly not visible from the top of the engine so I assume it is somewhere under it. Running at too low a temperature is liable to increase cylinder wear rates so I need to replace the element asap, any help would be gratefully received.

Hi, your temperature reading could be one of many thing including the thermostat, but not thermostat common problem for poor temp readings. the temp sender is a common faulty part, also the water pump has a habit of failing as well. the impeller is plastic and detaches from the spindle

I would get a code scan done first to rule out the sender then go form there.
