Webasto heater not kicking in.... Ideas?

Factory fitted Webasto in my T5 isn't doing its job....

Am "camping" out down in Italy. The nights are cold.

If I've run the engine for a while/been for a drive the heater will work. If I've been sat for a while or the heater has been on previously then it doesn't kick in, or if it does then it'll only run for 20 minutes and then I get the slight smell of diesel entering the cabin. Doesn't matter if I use the remote or hit the button.

Heater is the Webasto fitted by VW in the Caravelle.

Any easy fix for this or is it a trip to VW/Webasto specialist?

In the meantime I'll look for a sleeping bag liner tomorrow in town....

My ebersacher wouldn't ignite properly when I bought my van and locked out after 20 mins, a service of the combustion chamber mesh sorted it. Required a specific tool to get the 'glow plug' out. Not sure of Webasto specifics but can't be too dissimilar.

Yup.. Kinda what I thought. It fails to ignite each time. I don't know why but after a run it seems to manage it, but not if trying to ignite after it has already been on.

Don't know if it's an easy fix.

Have also alles on Transporter forum.

cheers

From the slight amount of reading I've done on them the ones fitted on Eurovans tend to either get fried or develop glow plug issues. Mine may or may not work, I'll only find out once the outside temperature sensor is fixed and everything stops thinking it's 73degC outside.

I am wondering if yours is perhaps tied to temperature of the system. I know mine, as fitted, is only a circuit heater for cold starts. But then why would it work if the engine has been running? Hmm. I'd be taking a look at it tbh.

Do you get a flashing light on the control unit? This can flash in a sequence that shows what the fault is. Search for fault codes and find out which model is fitted.

Control unit? You mean the display unit thingy console thing in front of the rear view mirror?

No, nothing there.

It shouldn't be dependant on outside temperature..

Pretty sure that it is just for heating the cabin... Warm air comes in, being blown at the windscreen.

Van came with a leisure battery under the driver seat for the heater/air con.

The display unit also let's me choose whether to heat or cool (via air con) the van when using the remote.

Is your leisure battery holding a decent charge? Could be the heater is draining it, hence it not starting second time around but ok if you've been for a drive and got some charge. You do need a decent battery to run them.
