Having just read the probs with DarrenW's heater,I now need some help.
Once car has warmed up and I put the heater on,I can feel the heat(by hand by the trans tunnel) for about 10 seconds then it starts to go cold.It does not matter whether the car has been running for 5 min or 1/2 hr,its still the same.Unless the outside temp is above 15*,my heater is as useless as tits on a bull.Have taken the heater hose connections off and flushed the heater out numerous times,but it still doesn't want to work properly.Alot of brown gunk(mud/dirt) came out of it.
My mates tdi(4 cars off the prod line from mine),works brilliantly.
When I bought the vehicle I think the previous owner cooked the engine ,cause it had a new head and various sundry bits.
Am thinking of putting some bi-carb soda down into the heater(how much do u put into a tdi to give it a clean???)for a cupla days.Have also heard that coke cola will also give a good clean(put into resevour tank) for a short time(ten mins),then drain,refill,start donk for 5 mins,drain then refill with coolant added.
Thanks for your thoughts in advance.
