[Arkaid]

2004 S4
Not sure on exact build date, but definitely late 03 sometime
64k miles
Driving in traffic and the car completely shut off like the battery was dead. No compression on any cylinders, pulled the motor and found that one of the pulleys in the back (cam tensioner maybe? Can't remember) had actually sheared off of its shaft and the valves and piston heads got absolutely rocked. About an inch of play on the pulley itself. Engine is being replaced with one out of an s4 cab.

add me to the list....
2005 S4 Avant
42k miles. I do not have much history. I purchased with 36k miles. Changed oil immidiately.
Burning 1qt every 400 miles

cyl 5 and 7 were scored the worst. other cyl had some minor scoring. Chain rattle got significantly worse in my short time as owner. Traces of guides found in my oil pan. compression was poor on said cylinders. exhaust valves leaking as well. Motor is a mess in every way

being replaced with brand new motor... out of pocket. Warranty denied claim
