I guess one of the first things is to ascertain how the water got in there.

the first time i seen it my mate was working with it shined a torch in the tank today checked it as it was stopped for 24hrs tank clear so it must be drawing air in from between the tank and the pump and that would be causing the juddering the gauze for the outlet to the pump could be chocked is there anything other thing you can think of thanks for your reply

Water can be from condensation
Park for 24 hours, drain the water off the bottom of the tank, being heavier than oil it will sink to the bottom

Couldn't find the other thread ........
The cloudiness in the oil might be air?
Unless rainwater or over use of the steam cleaner which is highly unlikely.

It's not going to be 1998. Series 3 stopped in about 1996 they then moved on to the 628 model in 1997.
