I will wait a day or so, but find someone who is good on Mercs. Cheers
Thank you. Can't believe I had the car for this long and didn't realise that. Can you tell me where they are situated? Presumably one for fronts, one for rear?
I ask also because it's hard to understand what can actually go wrong with these, I though they were just roughly spherical balls, to retain pressure in the system, they have no moving parts within them, just a pressure vessel? Or do they do more?
