Does anyone know if there is a common problem regarding the climate control on the Tig? I'm finding that the system doesn't get hot enough to warm the car even set at the highest temperature setting. I think during summer it didn't get cold enough either but at the moment isn't the heating side that's the issue. Did a 1.5hr drive today but just fel too cold for the setting it was on.

I sometimes find that playing around with the auto button kicks it back into life or it works quite random but there's definitely a problem. I have the climate control system where the temperature setting lights up around the dial as you turn it. I'm under warranty but would like to know if anyone else has suffered this problem and if its software or hardware related.

There was a TSB for the climactic (single zone) where new software fixed a random no response. Or the thermostat could have failed and the dumb gauge is not accurate to say so.

Software fix sounds simple enough but I have the dual climate control.

Gonna keep an eye on this one as this morning it was working fine. Had to turn down from 26 to 23 degrees as it got too warm. It must be a sticking sensor or something.

Hi

I too seem to have a problem with the dual zone climate control heating.

The passenger side heats up fine but the driver's side remains mainly cool with just a hint of warmth. If I put the drivers side up to about 26 it does get reasonably warm but still nowhere near the 20 of the passenger side.

On very cold days it seems to work fine on a short round town journey but perhaps this is just the auxiliary heater kicking in?

It is due for a service soon so I was thinking of asking for a diagnostic check, but as this is about £60 for the check and then more for any fix it would be great to get your views first.

Any thoughts?

Thanks

I've just started looking into this as we have the same problem with our 2011 170TDi 4 Motion Tiguan with Climate Control.

The car has 26,000 miles on the clock, has recently been serviced at the VW dealer, has had an air conditioning service etc.

The problems were first noticed when it started to get cold last year so probably Aug/Sept 2013.

The symptoms are:

Drive for more than an hour constantly without stopping (i.e. on the Motorway) and you start to notice that you're feeling cold. This is with the heating set to 22oC or there abouts. You turn the temp up a couple of degress, no real difference is heard but you wait. Then you put the temp up to max and the fan speed increases but the outlet from the vents is no more than before. This is as if a vent flap somewhere is stopping the air from getting out. Now you're really cold and you've switched the heated seats to try to help but it's not enough. You now press all of the vent buttons, you max out the fan speed as well as the temp. The fan can be heard to be working hard but there is still only a small amount of air coming out of the vents... and I mean all of the vents. Foot vents, windscreen vents, dash vents etc.

You pull off the motorway and come to a junction or you come into some traffic on the motorway for more than 2-3 minutes and all of a sudden you can hear the air flow change from behind the dash and all of a sudden, you've got plenty of hot air! You carry on your journey and it slowly cuts off again so that you're once again frozen and can't get the heat through.

Our Tiguan first started faulting whilst under warranty but it's just run out. Thankfully our VW dealer has had the car in 5 or 6 times now for the same problem and so because it's an ongoing issue, they're still dealing with it under the VW warranty.

So far, they have reset the ECU, then they've done an ECU software update (in fact the whole vehicle had all of the ECU's software updated at the time), then they've replaced the control unit in the dash as this houses the main temperature sensor (small round, looks like a button on the control panel) and they've had it in a few times more testing it to get it to fault but of course, they can't get it to go wrong because they're never driving it for long enough or in extreme enough weather conditions. They have driven it for 2 hours and not had it go wrong but that day was not that hot or cold.

I have plugged in (with Vag-Com) to check for faults (none found), to check various measuring blocks to see what the system is registering but can't find anything obvious.

Then around a month ago, I drove it (3-400 mile journey at varying times of the day) on a typical spring day and found that in the middle of the day when the sun was beating down, after an hour the air conditioning was not keeping me cold enough. Sure enough there wasn't enough air coming through the vents. No amount of pressing buttons etc made any difference but after coming to a stop in traffic, all of a sudden I was freezing cold with a very effective air conditioning system! Later that day on the return journey, it was 4oC outside! Yet again, I was bloody frozen and could get warm enough - same issue, not enough air coming out of the vents.

I am a VW nut through and through but this is starting to get on my wick. My wife is less than impressed to say the least, especially as we now have a 2 month old son. I suggested that we go with a VW for her as a good reliable car. Now I'm starting to regret it.

The car will go back again to VW but I know that they've been onto VW technical several times and have no idea what to do next.

I should add, the engine gets up to temp normally without issue. The heater/air conditioning work well on short journeys so the cooling system or air conditioning systems are not at fault in themselves.

Has anyone been through this already?

Thanks in advance.

I had an error code in VCDS and when I had issues with my Kenwood installation I mentioned a fault in the climatic control. When I picked it up they said it needed a software update. I didn't notice a physical fault only a code fault. I haven't rescanned but will before Sept. Service.

Part of Syncro's post stirred my mem. " Sure enough there wasn't enough air coming through on a typical spring day and found that in the middle of the day when the sun was beating down, after an hour the air conditioning was not keeping me cold enough sure enough there was not enough air coming through the vents." that there is a sensor in the mddle of the dash just under the windscreen that has a relationship with the AC temp controll and direct sunlight. this was related to a Touran which has a similar dash to the Tig.This might be worth investigating when trying to find out what is wrong.

Thanks, I'll look into this in more detail. I don't suppose you know the sensor name or designation?

I had a look in Elsawin and it is quoated as this :-

2 -

Sunlight penetration photosensor -G107- or sunlight penetration photosensor 2 -G134-

As I said it is in the centre of the dash in front of the windscreen (exposed) so you should see it.

I will explore further and maybe PM you.

Hi jayro, thanks for your input thus far on this subject. If your PM may help others and if you can share its contents, please post here as well.

Cheers,

Old Dog

Sorry, I hadn't read this when I posted mine today under Heating Efficiency. Is this a sensor problem?

Update:

The Tiguan went back in just before the warranty ran out and we said, 'Fix it and keep it as long as it takes to fix it... we're going on Holiday!'

So they did more testing and ended up changing a sensor which is part of the air conditioning system behind the dash. Apparently there have been a few instances of this sensor 'freezing up' due to it's location in relation to the air conditioning evaporator.

We have now had the car back and for 3 months, no re-occurrence of the problem.

If it comes back with the same problem, I'll let you know.

I'll also ask for more details as to which sensor they changed such as a part number etc.

That will help, as there is about six in total sensors for the sir con/heating.

I asked the question this morning and was told that it was indeed the Evaporator Temperature Sensor.

Part No. 1K0 907 543 G

I must stress that as with all modern cars, this part is probably not the correct part for your specific Tiguan due to options, year changes etc so please don't go fitting this to yours without checking if it's correct for your Tiguan first.
