hi my 04 multipla has had a replacement thermostat which has cured overheating but im getting no heat from the heater at all has anybody got a diagram showing were heater hoses should be on themostat im not sure if i got them back on in the right place, also is there a method for flushing the heater and bleeding it

Have you had a read of this thread?:

It seems there's a batch of thermostats doing the rounds that haven't been correctly machined. The port for feeding hot water to the cabin remained blocked off....

heater all sorted tried an old trick i have used before on older cars actually filling the cooling system under preasure with a submersible pump seems to have driven all the air out of the system and the heater now works well thanks

all problems solved now tracked it down to the water pump being faulty new one fitted all small issues dealt with and i am now enjoying driving my multipla
