Using Webasto Thermo Test, fault code is 2002, value is: 'no start'. Heater is a Thermo Top Z/C (water), it has the same BTS 141 in the control unit, which controls the glow plug. Derived unit definition. Thermo Top Z//C has no separate flame sensor, but uses glow plug as a flame sensor, as soon as glow plug is switched off (by measuring resistance, wich differs when unit is burning fuel).

You might know this all, of course. Heater starts normally, glow plug is on (burner insert/glow plug is new). Burner starts, fuel pump working, water gets warm (water pump is ok).

After 90 seconds glow plug is switched off, FD 'lamp' on Thermo Test is red, but 'flame detector measuring' is cancelled after a few second and fuel pump gets switched off. Consequently flame exstinguishes. Same cycle repeated, again fuel pump gets switched off after af few seconds. Unit turns off normally. As I said, fuel is burning and water gets warm during these two cycles.

I ordered the BTS 141 already, will arrive tomorrow. The mosfet controls the glow plug, so it must be responsible for ohm measuring, too? Resistance is no problem, I think, I exchanged the burner insert with glow plug for a new one already. Hello, do you have a Thermo top C/Z?

Does it start up at all? In model C/Z the glow plug works as flame guard, as soon as glowing is turned off. You might have to exchange the glow plug. Have a look at the english remarks in the middle of this norwegian page: It is cited from the UK Landrover forums: There the corresponding thread is only accessable after registerering. I exchanged the 1R0 resistor, because my glow plug was new and obviously not the sinner. Chipdrive driver card software download kostenlos musik downloaden.

The resistor's value was a good bit above 1 Ohm. But I only have a cheap Ohmmeter, which is certainly not accurate at such low values. The new resistor has 0,25 watts, which might be a bit low, but works well until now. If your Webasto does have a separate flame guard (as Thermo Top T or S), check or exchange that one. It should have brown cables, the glow plug has yellow ones.

Sorry for being inaccurate. I have a Thermo Top C, and the glow plug and burner is brand new. The Thermo Top reports 'Glow plug/flame guard short circuit' and indicates 0.005 Ohms in the Webasto diagnostic software. I measured the 1R0 in place, and focused on the 'near 1 value' (0.985), but obviously missed the Mega on my meter So, what I´m measuring is the resistance in the rest of the circuit.

Given the common way of measuring low Ohm loads (voltage divider), the 1R0 is needed as a known resistor to measure the voltage drop over the glow plug and calculating the unknown resistance. I was unable to find a smd resistor with the same form factor, so I ordered an ordinary axial resistor of 1W - hope that will do it Will report back when replaced.
