While recently getting my Rear suspension arm bearings replaced, the mechanic from a local garage fiddled with the strut. When the car was returned I noticed a small leak coming from the upper extension of the strut gaiter where the LHM return pipe goes into from a small crack in the rubber extension.
The references for the gaiter is number 4 in the image above (OEM 527233).
Apparently this gaiter is NFP. Any idea if other references for the gaiter and the clamp say from the C5 might fit?
Otherwise any suggestions for how I may attempt a repair.
