As of yesterday my B7 A4's engine has developed a rattle and misfire. The misfire isn't severe but is definitely noticeable under load, particularly at lower rpm. The speed of the rattle does change with engine rpm and sounds metallic/tappety to my layman's ear.
It's a 2.0 TFSI Quattro, with 120,000 miles but has had all its services. It's going into the garage tomorrow but just wondered if anyone had any thoughts?
P.S. Engine management light has NOT come on, nor have any other warning lights.
