Hi all,
After fixing the beeping noises in the dash, I thought I'd turn my attention to preventative maintenance; namely the sludge problems associated with audi long life servicing.
I've recently drained some jet black oil and re-filled with 10w/40 semi-synthetic with new oil filter. A week later and this 'new' oil has also gone black!
Is there any way of safely de-sludging the pick-up pipes etc without taking the pan off and without using any harsh additives, etc?
Regards,
Grant
