I have a 2010 (60 plate) Superb II. As elsewhere in this forum, it takes a long time to heat up, but my main concern is that the temperature distribution is poor. When the vents and screen are starting to blow warm, the footwell area continues to blow cold for much longer, and it's really uncomfortable having cold legs.

I asked the dealer to check it out, and they pronounced a clean bill of health after a diagnostics check. They said there were no DTCs registered, so I assume the various flaps and motors are doing what they should. they also said that air-bleed systems don't produce intense blasts of heat. I can't believe, though, that the heating is meant to perform so poorly (I have had many VAG cars from new, and none behaved like this) even on manual with air directed to the footwell, it's lukewarm

The only thing I think might explain this is an airlocked Matrix, which wouldn't show up on diagnostics, but I don't really know. Any other ideas?

Thanks.

mines similar, it never gives out REALLY hot air, always just luke-warm...

just thank god for heated seats in the cold weather!

Order placed for Superb in November and now, in March, five weeks before I get the car, comments start to appear about dodgy heaters- have I made a mistake in ordering a Superb?

Not sure if yours are semi auto, or the full wiz- bang climate control- would this make a difference? Also with my Avensis get more heat with aircon button off

The 2.0 CR engines are to effective and thus doesnt produce much heat. The only way to solve it is either with a diesel heater (Webasto, Eberspracher) or an electric one. Either or even both are fitted as standard in Scandinavia. Might be time for the UK to implement it in the UK factorystandards. Might add that a Webasto- or Eberheater can be retrofitted.

I wouldn't be getting the jitters just because two people have mentioned an issue with the heating system.

Mine is a 60 Plate Elegance CR170 and the heater is fine. I leave it on Auto all the time and I rarely adjust it which is a good sign of a climatronic system. Plenty of hot air to the footwell when demanded.

Once the engine is up to temperature it will be supplying water to the matrix at around 90 degrees C and should be more than able to supply hot air to the cabin.

As for the dodgy systems -

Are you getting good heating performance from the demist or face vents when the heating is on it's highest setting? If so, there isn't a problem with the heater matrix, if there was an issue, the heat output would be poor no matter where the air is sent in the car.

If there is a temperature sensor out of specification it could be mis reading the temperature and backing off the heat to the footwell. To be sure, they need to be checked against a calibrated thermometer whilst monitoring the sensor data via VCDS. a sensor can be out of spec and not be a fault as such.

DTCs aren't the be all and end all of car diagnostics and there is an almost total reliance on them. Just because the Climatronic isn't registering any faults doesn't mean everything is hunky-dory. You can run what is know as a basic setting via VCDS which cycles all of the air flaps so they are guaranteed to be in the correct position, I wonder if the dealer did this when they 'tested' the system?

I just leave mine on 22C too, and it does it's job as I rarely need to touch it. So like others have suggested, it sounds like something is a miss with yours.

The auto recirc is a great feature as well, works great in the crap London traffic, only works in auto it would seem.

I might tweak the temperature a little here and there, maybe down to 20 degrees at times.

I leave mine set to 19 and Auto, with AC all the time, I find 22 is way to hot for me.

Any diesel engine is thermally efficient and take a long time to warm up. Mine takes around 3 miles before I start to get any heat and a lot longer before the temp engine temp gets to 90c.

Never had any problems with the heat distribution, just stick it on auto and the sensors take care of everything. If you try and control it manually its very difficult to get it right. If the Auto light is not on then its in manual control, and you'll need to set the air distribution yourself.

+1. Crikey, 22 must be like sitting in an oven!

22 is nice, 24 for this time of year is better!

Altho, i would have like the internal temperature to be in half degrees, as my wifes car, which is lovely set op 21.5 - dont know why the outside is in half's, but the insides in wholes!

Al.

I miss the .5 degree adjustment on the old climatronic system, I found 20.5 just right for me, 21 is too warm and 20 can be too chilly at times.

"Fussy ******" I hear you all shout

I never run the AC unless it is required ie misted up or too warm to maintain the cabin temperature without it.

"Tight ******" I hear you all shout

I don't run the AC either, apart from the occasional blast for 5 mins to keep up the lubrication.

Where are they fitted as standard you say? On what models? And since when? To me it (Webasto) was the most costly option on my car (still worth every penny), and don't tell my SWMBO about it...

The compressor is a clutchless jobbie which means it is running all of the time. The cooling capacity is reduced around 2% but it ensures the drive shaft seal is kept lubricated and therefore gas tight. My last Octavia did about 145,000 miles when I put her out to pasture and the air con performance was as good on the day I let her go as it was the day I took delivery and it never needed a drop of R134a in all of that time.

Despite that, I give it a good full blast every now and then to pump everything round the system a few times.

I can answer here. Webasto are not fitted as standard (at least not in Sweden), on no model at all. The cost for this option is about 1000 Euro.

Good to hear that you like the Webasto, it was the most important option for me when I ordered mine.

I can comment here as well.

This is another case when people write fast, like thinking in their minds, and not checking if it has a correct meaning or is it ambivalent.

Webasto (in case of VAG) is never fitted as standard. Also (Calix) electrical preheating. And why should it be?!

Additional electric heater is standard on Superbs here, especially useful for diesels as they're way too economic, but if one wants a distance controlled preheating it has to be ordered as an option.

When at the dealers' they suggested to me to order the CR without the Webasto, as otherwise the additional el. heater will be excluded and then retrofit the preheater over here. Cost will be the same but I will retain the on-board electric one for personal convenience.

What regards the poor warm-up on Superbs, then there was an article in Auto, Motor & Sport (I think), testing some diesels in winter conditions and believe me - Superb wasn't one of the first ones. I didn't mind as I'd take the Webasto anyway.
