Did you notice if anything would stop the squeak like depressing the clutch?

Interesting. My a160 with the same but smaller engine has the same problem and its going back again as issue has not been resolved yet. What you are reporting is identical. Let me know how you get on over the next few days

No difference if i engage clutch or not ,sqeaking when idling and driving upto 20 mph delivered to home washed and hoovered no more speaking.
My dad has a A180 cdi and his was a pulley cost him 600 pounds had to drop engine 3inches and replaced pulleys and belt out of warranty .

Our B180 had something similar and they replaced the Poly-V belt with the new design under warranty, also replaced the tensioners etc. Trouble is the new ones dont seem to last as long as they are already reporting wear on this one at 2.5 years old vs the old one that was nearly 5 years old.....
