Volkswagen Polo no heat in car

Check flow of water through heater hose at bulkhead entering heater matrix .If getting a flow then must be a internal fault on
heater flap inside heater unit . This is a previous reply on same subject , not sure if it applies to your year .

Re: Polo Heater problems
I too have this problem. This is a common problem with Polo's

see http://www.vwaudiforum.co.uk/forum//...ead.php?t=3343

I have posted here and other forums before but no one is expert enough to be able to conclusively say what a simple fix is.

The fix seems to be quite complex.
Basically, there are tow motorised flaps in the heater control. One that controls the temperature and one that controls the fresh air intake. Both these motors are pretty unreliable and tend to get jammed intermitenly. I have checked this on my car with VAG-COM diagnostics cable connected to my laptop and get the following fault codes:

01271 - Positioning Motor for Temperature Flap (V68)
30-10 - Open or Short to B+ - Intermittent
01596 - Motor for Outside/Recirculated Air Flap (V154)
30-00 - Open or Short to B+

The fix is to replace these motors (V68 and V154). They are not cheap but the real problem is getting to them. To do it properly, the whole dashboad has to be removed to get to the heater mechanism. Which requires removing the steering wheel (which requires removing the battery lead which disables the airbags).

VW *********** quoted me £390 + vat for parts and labour !!

I have learned to live with the problem by trying one of these workarounds:

1. turn temp dial to coldest and close the central airvents for 1 minute or two while the vent dial is set to DEMIST. Then open the central vent fans -- that then lowers teh temp to the coldest.
or
2. turnthe fan speed to ZERO for a minute or two and then to 1. That will then reset the temp to the coldest.

Try that to see if it works for you.

Heater problems
The part is £71.12 but it takes hours to fit as the whole facia has to come out. I also recommend to my customers that we replace the other motors when we are in there but they are usually faulty anyway so it isn’t a good idea not too. It isn’t just Polo’s either, Golf’s, Passat’s, Octavia-they all suffer from this but the Polo is especially bad.

your car sounds like it is in a bad way you say there is no heat into car but have you got air flow into the car when you put fan on if there is no air flow then first thing to check is pollen filter situated under the scuttle panel on the n/s passenger side not often checked as people assume old cars dont have them if blocked you will not get air flow into car you said in other post you had water leak into car if antifreeze you will smell it and you will have a leak from heater rad (matrix) this is a major job all dash has to come out to access heater box this also has to be moved forward all cooling systems run under pressure but if exessive coolant wiil come out of pressure cap when it exeeds cap pressure usually caused by a jammed thermostat but engine would overheat poor coolant flow water pump (broken or loose impeller )or combustion gases cyl head gasket this would also cause air locks in cooling system that will prevent heater from delivering hot air
