Polo heater problem

[kelseyh]

I can't believe VW don't consider this as a fairly common fault, seem like lots of us have suffered. I don't rate the polo for build quailty at all, may have another fault, was driving down when suddenly the power dropped off for a second, felt like the car was braking, then suddenly returned back to normal. Oh well hopefully that doesnt get worse.

Got it all sorted, cost a bit but worth it for me cos it wasn't holding any temps, just really hot or really cold. Now it stays at an ideal temp

Hi, My first post with VWAudi forum.
I have just bought our polo 1.9TDI sport (2003) about 2 months ago and also have the same problems with the heater.
I can regulate this to about 18Deg anything after it then goes roasting!!!(Car has aircon)
I tried this the other day & seemed to work for all of 10 mins.....
Removed the heater dial panel, as suspected that the pot for the temp control was not working corectly. I sprayed this out with WD40, blew it dry & put it back together again.
Like I said, this actually worked. When i set it to 22Deg, it felt nice n warm.
Turned it to 26 & got roasting! turned back to 20 Deg & got nice n cool again!!!
Could the fault possible be conected to the control unit itself???
If anyone has tred replacing this, then PLEASE post a reply with the results, as this is starting to drive me mental!!!

Many thanks,
Martin
