For my interest (and possibly others) I will try a quick experiment over the next couple of days to see the effectiveness of the heater using an ODB II reader and the torque pro app which gives exact coolant temps to see what effect the automatic auxiliary heater has. Unless anyone has any better ideas I plan to put the heater to about 25c and then let the car idle for 5 min from cold, one morning with the auxiliary heater ticked and one without.

 

Can anyone tell me where the OBD port is? Under the steering column?

I could be getting mixed up here, but are people expecting the electric auxiliary heater (not the webasto) to warm the engine/coolant up more quickly?

 

The electric aux heater won't change the coolant temperature, at least not directly, as it sits in the HVAC system to heat the cabin air whilst the engine warms up. The alternator will be working harder to generate the extra 1KW which in turn means the engine is working harder and could warm the coolant up slightly more quickly.

 

It would be more meaningful to measure the cabin air temperature.

"I could be getting mixed up here, but are people expecting the electric auxiliary heater (not the webasto) to warm the engine/coolant up more quickly? "

 

Not for me. I am interested in warming up the interior as quickly as possible which is why the interest in the supplementary heat coil. So I agree with you; it is how quickly warmed air is available for the interior that is of interest.

 

I drew attention to the design of the cooling system in the EA288 series because that does mean the cooling system can provide warm air for the interior much more quickly than expected without any form of supplementary heating.

 

I can't work out from this thread what UK cars should have this check box option for supplementary heater. Mine is a 1.4 ACT petrol engine SE L ordered with optional front heated screen. It was delivered December 2015, but my air con menu set up doesn't have the third entry for supplementary heater. In saying that, being petrol it warms up pretty quickly compared with diesel so maybe would not be specified anyhow.

 

 

Thinking about that information point it begins to look like those cars with the heated windscreen, rather than model designation, may not have the supplementary heater. That might make a bit of sense as you would need warm air as soon as possible if you don't have a heated screen ??

Thanks seems I am getting mixed up, was expecting it to warm coolant which in turn would warm cabin but from your post it works differently. Will abandon my experiment!

I checked on mine again today. L&K without the supplementary heating option shown but with heated screen.

 

Ambient temp 5C and with the climatronic set to 24C I was getting warm air within 2 miles; not hot air but warm rather than cold. So no different to a petrol engine from memory.

 

That feels like confirmation to me that the micro circuit works well; what it means re the supplementary heating I have no idea  :doh:

Just had a play with VCDS and look what I have found:

 

Before:

 

 

 

Now:

 

 

So I have ticked the “Automatic auxiliary heater” box and done a scan... no fault codes, will find out later if the car warms up any earlier or if it is missing some hardware.

 

Mine has always started the warm up inside after 2 / 3 miles and is usually fully warm after 5 /6 miles.

 

Rescanned the car today and although there were no fault codes under the HVAC (where the coding is) there were a couple under the engine, due to the Aux heater relays not being present.

Hello Everyone, New to the forum!

 

Can you please let me know , how you managed to make this option appear?

I have installed all the hardware according to the wiring diagrams, relays, fuses, heater, wiring, to connect it to ECU, i have checked the box "3 stage 1000W installed" on vcds, but i can't make this option appear. Can you please let me know?

Just to update, that this feature is now appearing on the TSI petrol engines, the 1.5 150PS and 2.0 190PS TSI's.

I have this option and mine is a 1.5TSI

The electric auxilliary heater is on all the facelift models now, and as mentioned it just helps get the cabin up to temperature on cold days.  I mailed SUK a couple of times as I saw it in the brochure / spec for the facelift when I bought mine. It's been around in one form or anopther on Ford's / VW's / Audi's for a while, but nothing like a Webasto heater that will prewarm the engine.

 

I've had my car a week now and can confirm it does work It's not roasting, but on a -2c day last weekend, the cabin was at a comfortable / tolerable  temperature (For a Shirt / T-Shirt wearer like myself)  by the time I'd driven 300 yards to the end of my street.

 

 

"Thank you for your recent contact with ŠKODA Customer Services. Please accept my apologies for the delay in my response.

I can confirm that electrical auxiliary heating will come as standard with the SUPERB SEL Estate.

 

The electric auxiliary heater is there to aid the heating system get up to temperature on cold starts – it is much like having a hair dryer in the heater whilst the engine gets up to a temperature which the system can use for the hot air.  

This system cannot be operated independently from the normal operation/ running of the engine – it comes on when you start the ignition (it may come on when you unlock the car

My post was from back in 2016 😁

When I ordered my new one last week the salesman said they can now offer LHD as an option for £500.

 

I wonder if European dealers have a similar option to offer RHD?  If they do then to get the Webasto you order a RHD car in Norway . . .

Yeah, that was a while back!!

 

Still wasn't sure what it does or how it works, but Fluffmeister has cleared that up. It's a nice feature to have a warm car quickly, although I've always found (Skoda) petrol cars to warm up quite rapidly.
