Automatic Supplementary Heater

[Rob123]

When I got my car I noticed a new setting that wasn't on my 14 plate Octavia Elegance.  In the A/C settings there is 'Automatic Supplementary Heater'. 

 

I was surprised to see this because I've not seen any info about it before, other than Auxiliary Heating, which is different.

 

Well, now the cold weather is here, I've noticed just how good it is.  My 2014 2.0l TDI O3 took forever to warm up during the winter, whereas my new '67 2.0l TDI SE-L takes about 30 seconds before it starts blowing warm air.  Its so much better, cant believe its not mentioned in more places (or anywhere for that matter - its not even in the manual!).

Haven't noticed this on my 16 plate vrs but I will looking for it first thing in the morning! Hope I have it!!

I've got it on my 66 plate Scout, but have not noticed any difference, but will test this week with it on and off and report back.

I have this on a 2017 1.5TSi SE L DSG Hatchback - car does heat up quickly. My previous Octavia a 2.0TDi DSG Estate took several miles and about 10 minutes before appreciable warmth came through. Also noticed on the TSi that the water temperature is at 90 in less than a mile (this must be the supplementary heater) compared to the TDi 4 or 5 miles. A great improvement all round.

Making some sort of sense.

Is the supplementary heater just a ceramic heater to warm the cabin up quickly as ford and others have been doing for a while or is it more?

I had this on my 2005 A3 TDi - electric heater elements to warm the air before the Engine coolant warmed up.

In both instances these comparisons are warm up times between petrol engines vs diesel engines.

 

Never been a sensible comparison really. Sorry to point this out.

My SE 1.4Tsi does not have that option under Climatronic.  Has the option for automatic air circulation though. No idea when that kicks in, my Hyundai SIII coupe had a hydrocarbon pollution detector iirc and switched once when the car was getting fumy.

Wasn't comparing in that sense just pleasantly surprised after 12 years or diesel. I'd forgotten how fast petrol engines warm up although the supplementary heater helps in this respect I don't know.

 

Noticed this morning once the engine is running the needle can be seen to move to the 90 position within a few minutes. When I first got the car I was concerned about this and checked coolant levels but they were OK and have been rock solid since.

I had one of those (an optional extra) on my previous Audi B7 RS4 - it worked fine when the car in front was a petrol but it didn't detect the emissions from any diesel so we still had to manually select recirculation mode, so I won't bother paying extra for the option again.

So does the 1.4Tsi engine have this heater in some applications? I suspect it is a diesel only thing. Having had an Octavia diesel I'm well aware of the slow diesel warm up sagas.

Never had it on my 2016 2.0 TDi DSG diesel estate - got it on my 2017 1.5 TSi DSG.

Interesting.  I had the electical heater in a Passat B5.5 1.9 TDI but the heating was no better overall than my recent 2l PDI Octavia Iirc.

Cos it's a petrol. Warms up fast enough. Doesn't need one. Although it seems some petrol's have it.

I'm not complaining- mine warms up fast- but I keep finding new menus and ways in to unexpected options.

[JamiePvrs]

It's on my 16 plate vrs tdi

[nkadovic]

On my 2014 2.0tdi also
