W203 EZS and BE keys

**papalos_** · 23rd November, 2018, 11:11 AM

Hi mates!

I programmed a BE key for W203 with HC908 EZS and I've got some problems. During driving the car, the consumers are powering off, the suction fan is working at max RPM and the faults:

B1025 The input signal 'circuit 15' is not o.k.
B1032 The input signal 'circuit 15R' is not o.k.

are recording on SAM-F control unit. I tried many EZS(2035450108, 2035450308, 2035450508) but always I have the same problem. The original keys seem to work good.

Is there any known compatibility issue between HC908 based EZS and BE china keys? I tried the VVDI keys and 2 batteries keys, always the same problem...

Best Regards

The one I programmed is from Xhorse and the other a two batteries BE key.

So the next evidence that those xhorse keys are not 100% working (as been said) and I think none of BE keys will ever work 100%.

You mean that BE keys are not working 100% generally or on HC908 based EZS?

I'm just saying you are the next person who proved that Xhorse BE keys are not 100% compatible with all types of EIS as it's being advertised.
