Polo 1.6 TDI heater problem

[dgirllamius]

Hi there,

Hopefully someone can help me. I have a 1.6 TDI Polo (2012) and she's having problems with her heating.

I only really drive her to work and sometimes it works perfectly but sometimes it plays about.

The heating system I have is the electronic one (I have no idea what it's called), not the usual one with knobs.

If I set it to come out at my feet, it comes out at the windscreen instead. The same can happen when I want it in my face, again, comes out at the windscreen.

Sometimes it's set to HI and comes out cold (sometimes the other way round, set to LO and comes out like the blazing fires of hell).

If I turn the engine off and on again, it'll work fine (sometimes not, it's totally random).

I've got her booked in at the workshop but I'm just wondering what it could possibly be. It's doing my head in.

Thanks in advance!

nightmare

the autel vag505 will also do if your on a budget, it will test the heating system, if there is a fault


there are lots of motorisied flaps and a nightmare to get into. Its trying find out which one is faulty, or ones

I don't have anything like that. My husband does have something which plugs in under the steering wheel but I have no idea what it is or if it can see what's wrong.

I'm just hoping it's not going to cost an arm and leg to repair. Sometimes it works for days and then one time it won't. Yesterday when driving home from work it wouldn't blow out of the windscreen vents even though I had it set to that but this morning it worked perfectly fine. The bloke at the garage said it might be difficult to diagnose when it's random but hopefully he'll find the problem. I'm driving home on the 9th and it's a 12 hour drive, I don't want it failing on me 🤤

does it work on Auto or Econ ?

Auto is the air con & Econ is air con off

If it is more stable on one, then leave on it all the time. As you have a diesel, leaving it on Auto will have no effect on fuel economy


I would also just leave the air blowing onto the windscreen all the time, if a motorisied flap is failing, better just leave it in one position
