Hey! :)

There would be a small problem with Webasto. When cold, Webasto starts to turn on the cabin, the heater starts rotating in less than 1min, but turns off soon. Where should you go for troubleshooting?

Car info:
VW T5 MY10

Parts already replaced:
Original Webasto ecu has been repaired.
Fireplace and glow plug renewed.
Circulating water pump renewed.

Hm since there is no error logged after 2. Round it is a bit unclear.

2. Round was really scanned after the Heater was turned on, with the short Self-Turn-Off ?
Or was is directly after Error Clear ?

Else you see the Two Error from 1. Round

00664 - Fuel gauge
002 - Lower Limit Exceeded - Intermittent

Fuel is clear, as long as Tank is near empty the Heater will stop.

So the other one needs to be looked deeper:


01416 - Signal for Fresh Air Blower Activation
007 - Short to Ground - Intermittent

Looks like a problem with the Air Blower Motor

The second round is run immediately after the first round. After this, the functionality of Webasto was tested, but the problem still occurred even though the fault codes were reset -> 01416 - Signal for Fresh Air Blower Activation 007 - Short to Ground - Intermittent.

So does this section mean this:Fresh air blower?

Yes, that is the Fresh air blower of the Heater, that i thought about.

BUT, see here: http://wiki.ross-tech.com/wiki/index.php/01273

That makes more sense, because the Heater only does have a "Combustion Air Blower" or so, not realy a Fresh Air Blower in my mind ...

Probably in this case the Heater is talking about the Car Blower which pumps the Air into the Car ?
Probably only a bad cabling ?
