Hi all,

Hoping someone may be able to help. I have a yellow power steering light on, was intermittent, now it wont clear. Had it scanned:

Obviously I am dreading a potential £4k bill for a new rack....

Has anyone come across this before?

Thanks in advance

Not sure if this helps much but I had this intermittently come on and off for about 3 months and it just went away.

It is a covered apart as part of the Audi extended warranty. Which is £1,500 a year. You can buy it online and the car isn’t checked. Just a 30 day hold on no claims. So if you can make it thru 30 days, may be cheaper to get the warranty?
