Engine light issue on Audi A4 1.8T 2002

[KoDen]

Hi everyone. I need help as I'm have no more ideas what I need to do to fix that issue. I've got engine management light is on. Error code reader tells me there are two error codes. That are 16502 and 18062. Engine idle speed is always the same( you can see it on the picture below), same when the engine is cold or hot. As well you can see on the picture, what engine temperature indicator is always at the bottom, despite you just started or been driving for hours.

Please help, as I just no idea what to do next.

P. S. So far I've changed sensor behind the engine( between engine and windscreen). As well one at the bottom of radiator on the left hand side( if you are in the car). Plus I've changed thermostat with sensor in it as well.

At the moment I have no idea what to do. Any suggestion will be appreciated.

Thank you.

You should get it scanned with VCDS and check temp sensor outputs, also 18062 is for instrument cluster fault, VCDS scan should show up if cluster is faulty.

My mistake, you're posting in the Tech Shed, I assumed you had PC issues.

I'll move this to the Audi A4 B6 section (your dash image suggests you have a B6, do let me know if I'm wrong though).

Edit:

16502 - http://wiki.ross-tech.com/wiki/index...2/P0118/000280 - cheap and quick solution would be to replace the CTS.
18062 - Often caused by a faulty CTS.
