That sounds about right, the idle speed may not even be manually settable due to emissions regulations.
I know for sure you can't adjust the idle mixture anymore; that is determined by sensors and the on-board computer.
There may still be adjustments on some cars but they are often sealed with lead to avoid tinkering.

judging by the amount of km it has done i would say the rpm drive is faulty, this measures the amount of rotation in the camshaft and shows the "revolutions per minute". when this goes faulty it stops the read out on the dial, so you want to be looking for a device that measures the speed that the engine is turning, if you have, replace it and it should solve the problem

Invest in a decent 'vagcom' diagnostic reader off eBay! This may help find any problems caused by the cars computer...
Other than that, how old is your golf? And when was the last service
