Testi I like that I can still utilize my Webasto when the fuel tank is near E. With the amount of fuel that it uses I'm not worried about running my tank dry. Temps have plummeted to -20's C here and I have yet to have one cold start on my Cummins this season. I start my engine and it's already at 140-155*F. You can actually feel the heat coming out from the grille if you walk around the front.Did you have any issues when you fired yours up the first time? Finally hooked mine up last night and the 7 day timer will not power up at all The second the power and ground where hooked to the battery the units pump and blower fan kick on but that is all it will do. Make sure your timer is wired up correctly.

You should have 3 wires connected for the timer. A red, black and brown. I believe there is a green as well but you do not use this one. As long as those 3 wires are connected correctly the timer should power up when you connect the main power and ground wires for the Webasto.

You may also need to reset the Webasto, sounds like it may be locked out. If you have the instruction manual that came with the heater check out section 6. This will give you step by step instruction on resetting it. If all of the wiring is good and connected correctly and a reset doesn't work, the control module may be faulty.

If you don't have the instruction manual, go here. The unit should not power up when power and ground wires are connected. Unless there is a short in the switch wiring for the switch/timer. Or the timer is faulty. No issues with mine, just had to start it a few times to get fuel to the unit.
