1999 156 2.0TS water leak (not footwell!)
I have a 1999 156 2.0TS. Where the oil filter screws on, two alloy pipes feed water in/out of the oil filter mount. I have been told this is a basic oil/water heat exchanger.
About 8 months ago, BOTH of these pipes sprung a leak. Each was a tiny pinhole right on the 'elbow' of the pipe right-angle. Both were patched up with metal repair paste then the whole part replaced.
Today, ANOTHER leak has sprung!! Exactly the same, a pinhole on the right angle.
Has anyone else seen this happen?
