vw sharan aux heater

Post by vw lee »

Can anybody tell me why I've got clouds of white smoke bellowing from underneath the rear of my vw sharan, I think it has got something to do with the rear auxiliary heater. It happened once before about a year ago & now it has returned.

Whats going on :?: :?: :?: :?: :?: :?: :?: :?:

It's just had a full service last week, how do you go about servicing the heater? Is a job for a pro or is it diy?

Ah, so he serviced the car not the heater?.
Look at this website http://butlertechnik.com/" onclick="window.open(this.href);return false; about halfway down you can choose the model heater you've got and see if they do a service kit

I will most probably have a manual - presumably it is a Webasto?

They work when the ambient temp drops, on a T4 it's 5°c.
If it's cold enough the aux heater comes on and assists the engine warming up to give decent heaters.

It is most probably just in need of a de-coke - the clouds of smoke shows that the glow pin isn't reaching the correct temp at start up.

Was it smoke or just steam? Not unusual to emit steam if there is high humidity or condensation in the unit.

I wouldn't have thought that a bit of condensation would be described as clouds of smoke whereas incomplete heating of the fuel on startup truly is a cloud. It is like a peas-souper - ask Trucker as his glow plug fouled and he was laying down a smoke screen!

Are they all Webasto type aux heaters? We've got one in our old heap of a runabout T-reg petrol Sharan but the car is dying fast (I blame the 50% F0rd influence) but I've never investigated it. I will now :wink:

It is smoke. No doubt about it. Going to have a closer look this weekend. The misses was out in the car today but no sign of any smoke, that's the strange part :?
