DEF information

[CCFROMFL]

I have a 2011 Phaeton 40' DP. Does anyone know how much the DEF tank holds ? Is there any DEF gauge in the instrument cluster ?

Thanks,

13 gallons according to the 2012 brochure which is probably the same as 2011

Any DEF equipped coach I've ever been in has the same DEF level gauge, regardless of brand. Ours is at the bottom of the fuel gauge.


With the ignition on there will be four green squares when the tank is full. Those squares will go off as the level drops and I believe may turn yellow and ultimately red if the tank is allowed to get too low. I can't confirm the latter, I've never let the level get below half.

Thanks to all .... the Phaeton is new to me and your information is appreciated.
