....sounds like running water ???? It's going to Fernhurst tomorrow for the first service since I've had it, might need to turn over a bulding society this afternoon to pay the bill !
My Griff 4.0 did this. I think it's air in the heating system. Not dnagerous in itself but I suppose it will reduce the efficiency of the system (weak laughter).
There was a funny noise coming from the passenger footwell of my Chimaera but further investigation revealed Mrs Jayteens had forgotten to put her seatbelt on.
Cheers Simpo, thinking about it I have not used the heating since I bought. It's only in the last week that I've tried, and only in the last week that I've noticed the noise! 2+2 = ???
