W126 1991 H Reg 420 SEL - Squeal on acceleration
Recently my 1991 H Reg W126 has a high pitched squeal on acceleration. It's intermittent, but happens more often than not, and appears to be worse the colder the weather is.
Other than the irritating noise, it seems to drive fine, but is quite embarrassing and I obviously want to get it sorted to avoid any potential damage.
Any thoughts on what it could be and remedies would be very appreciated

TIA all
