Aux Heater

[Patrick-Irish]

It was cold this morning so I thought I'd try out the auxiliary heater for the first time. I switched it on manually and it made healthy sounding noises like it was revving up ..... air was pumping through the vents etc. I checked up on it a few times, listening outside the car and could clearly hear the fan running away. It ran for 30 minutes or so.

I was rubbing my hands together as I left the house at the thought of getting into a nicely warmed up car. But it was cold. The temperature felt just like nothing had happened.

Any ideas ? Have I done something wrong or missed something ?

Been done to death this one but Have you got Aux heating or Aux vent? What does it say on your screen? I did the same as you last year only to find a cold car

[Patrick-Irish]

The screen says Aux Vent. Is there a difference ?

Could you feel and smell exhaust fumes from the left side of the car?There is a small exhaust outlet there.....

If it says Aux vent then its just cool ventilation. If it states Aux heating then its remote heating. You can buy a £35 maplin relay and remote that will enable yo to switch the heater on from say the house on those cold mornings.
hope this helps

No, couldn't feel or smell anything.

Looks like it's a cooler I've got as opposed to a heater, based on thedweeb's post. Fat lot of good that is in the winter then ey ??!

When does it switch from Vent to Heat? Is that depending on the outside temp or do I miss something here?

Well I don't know .... the message I'm taking here is that either you've got an Aux Vent or an Aux Heater, not both.

Anyone know any better ??

Manual says:

You can use this system to ventilate the
interior and lower its temperature, using
the blower of the automatic climate
control.
The independent ventilation system is
operated via the Multi-Information
display (MID), refer to page 85 or via the
onboard computer, refer to the sepa-
rate Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also switch it on
and off directly. Since the system uses
a substantial amount of electrical
current, you should refrain from
switching it on twice in succession
without allowing the battery to be
recharged in normal operation between
use.
When a preselected activation time is
set, the independent ventilation system
is operational at outside temperatures
above +60 7 (+16 6), or by direct
switch activation. It cannot be switched
on when the vehicle is moving.
The air emerges via the vent outlets for
the upper body. Therefore, the vent
outlets must be open for the system to
operate.

No word on heating .... hm..

I f you have aux vent on the obc then it will blow cold air only. If you have aux heating then you have an expensive optional extra that alows you to blow hot air into the cabin area via the webasto heater under the bonnet.If it was specked when the car was bough originaly then you would also have a remote keyfob that would activate the heater from the comfort of your home
This option was mainly on diesels as they already have the webasto heater fitted which was put in to pre heat the heavy/thick oil in the diesel engines.However it was an option on petrol models but an expensive one due to needing the webasto. HTH
