He had allready got himself a job for saturday working on his brothers disco so maybe next sat now. Said it may be worth changing it and bleeding the system tho.
Certainly worth a try not as expensive as trying other parts will let you know. He is allowed to do all his own private jobs on a saturday so will see if he is busy tomorrow.
When i first put a thread on the forum Big D said check the fluid level but all ok. Might have to look into changing the fluid then does it have a shelf life ? Great news on the Pup !
