Just wanted to pass on this useful bit of info to SL owners.
Topped up the Windscreen Washer Bottle yesterday until it brimmed. Water level went down and I had a leak under the front right wheel. The water actually runs down the inside of the wheel arch cover. Found out from my friendly MB mechanic that where the black filler tube in the engine bay meets the actual washer bottle there is no rubber seal and it's not bonded, so if you overfil the bottle it will leak out at the joint until it makes it's own level at the top. This is quite normal and is common on SLs and SLKs - nothing to worry about. The bottle has a 7 litre capacity and the warning message comes on at 2 litres so the best advice is when the light comes on add slightly less than 5 litres and it shouldn't overflow the joint. Various threads have been posted about splits in water bottles and drain plugs leaking. The R230 has no drain plug. Hope this stops any worries about hidden problems. Happy motoring.
