Volkswagen New Bora engine can not be started occasionally

A mileage OBD2 Code Scanner of only 800 km, equipped with the BWH engine Volkswagen New Bora sedan. Reflects the owner: car engine can not be started occasionally, and on the dashboard the SAFE indicator (Figure 1).
Pick-up: with VAS5052 detection, fault codes stored in the engine system 16897, its meaning is anti-the starter key error; fault for B104B31 anti-starter system, its meaning is the key no signal; other systems normal. Caused by the fault of the car, according to the analysis of the test results, possible causes of a key, the reader coil failure; Anti starting system control unit (meter) internal failure; relevant line failure.

According obd2 software to the line between the circuit (Figure 2) the check reader coil (terminal T2X / 1, terminal T2X / 2) to the instrument (terminal T32/17, terminal T32/18). Examination was normal. Another key test, the failure is still the same, the probability of failure due to the two keys at the same time is very small, so the fault is likely to be anti-starter system control unit J362 (in instrument cluster J285), an internal fault.

Chen therefore Car OBD2 Tools exclude: replacement with a combination of anti-starter system control unit (J362) instrument (J285), the VAS5052A guide function matching combination meter and keys after the test. Troubleshooting.

Special note: replace the combination meter (J285), press and hold the the instrument lower right car diagnosis tool corner of the zero key instrument initialization.
