Hi all - new member here and seeking help for the first time 

I have a diesel Q5 2ltr s line 2019 and a warning light has appeared on the dash stating

Four wheel drive fault. You can continue driving. Please contact workshop.

any ideas what this is likely to be and hope it’s nothing serious 

replies will be acknowledged 

many thanks

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂  

You'll need a diagnostic check to see if any fault codes flag up but it could be an issue with the quattro system 

Thanks Steve 

I shall take it for a diagnostic check asap

Please keep us posted on how you get on 

Hi steve 

had a OBD check done by my mechanic and its coming up as code C05ED00 which states a problem specfically with the AWD clutch 'B' stuck engaged linked to the J 492 control moduleand a worn shift fork in the rear diff and require specialised repair with differential disassembly and replacment of faulty shift fork with an audi repair kit. Hes looking into the costing for me but i'm a little cheesed off because the car as only done 32000 miles and surley this should happen on a car with this low milage.

not sure what the outcome will be. 

is this something that is common and have you heard of this before-sounds expensive to me🙁

hope this info is of use to you

Bill
