Car milage display not showing properly can make out some of the figures on th display bit some digits are half dispayed, what can i do

Ask a local mechanic recomended by a friend to have a look as iam not sure but i do suspect that the speedo head unit has packed up and this is a expensive bit of kit .

CHECK ALL FUSES.

1/2 full is fine,it allows expansion and contraction of the coolant fluid.change antifreeze every 3 years.

An egr does nothing good for your car or mileage. However it does quite a bit for the environment. It takes some gases (I can't remember the exact name) from your exhaust and puts it back in the intake so it would be reburned. This doesn't help or really hurt the engine but it makes your exhaust less polluting.

You can't get freon anymore, so you need to convert your A/C to R-134.

this is a failure of the digital read out computer.

Sorry but unless you have very good working knowledge of small intergrated circuits then you will not fix it....There are comon issues with them. You can remove it and have a dealer send it out for you for repair but you cant drive the vehicle. If you do the milage will change in the pcm but will not match the odometer so the pcm will lock the vehicle when you put it back in. Your best bet is to have the dealer send it out or buy a new one with the milage programed into it.

First - did you use the correct viscosity - SAE spec ?
Using a thiner oil can affect oil pressures.
Presuming that you did, and oil levels are ok, then I would check if this is a standard service light come one. They are programmed to light after a certain milage since the last change - and this seems likely if you have just done it (before light came on to remind you)

Try resetting it. This works for most models -
Turn ignition on - so you get display/ lights etc.
Set trip meter to show milage.
Turn ignition off.
Press trip meter button - and keep pressing it while turning ignition to on again.
Light should blink and go out.
Take finger off trip meter.
Depending on model - you may get some figures - 1200 , 800 , etc. This alows you to change service interval if you want - but if not - then just turn ignition off again.
Light should stay off.

If this doesn't solve it, I'll look for specific info of how to do it - or start checking other possible causes to check.

you have a wire loose or poor connection or the cluster could be going bad.

hello i also had this problem but it was soon sorted when i took my glasses off my head and put them on properly and if that dosent work take it to your local audi dealer glad to help regards mr fixit
