Estava pesquisando na net e parece-me um problema corriqueiro em 2008, talvez até um problema conhecido pela BMW. ACho que não custa nada imprimir e apresentar provas que o problema existiu em algum momento lá atrás (2006 a 2008).
Exemplo:
There is a PUMA Measure on the BMW Online System that your dealer should be well acquainted with...
US 11588817-04 - "EWS" fault display in the instrument cluster
Complaint
Motorcycle does not start. "EWS" is intermittently or permanently displayed in the instrument cluster
Cause
1. The battery was previously disconnected and was connected before the ignition was switched on for the first time.
2. There are increasing failures of the EWS ring aerial on motorcycles manufactured on or after 18.9.2006
Measure
In rare cases, the BSM-K or BMS-KP software may not have been started (booted) completely correctly when the ignition is switched on. A fully booted BMS-K(P) always shows the gear indicator in the instrument panel, provided that the gearbox potentiometer is NOT faulty.
1. If the "EWS" display appears in the instrument panel and the low-beam headlight lights up when the ignition is switched on for the first time after the battery has been connected, it is NOT a ring aerial fault.
It is a booting error in the BMS-K(P). Do NOT replace any parts.
The fault does NOT occur on either of the two K25MO models or the K71/K72 models.
Once the ignition has been switched on for a second time, the EWS system functions normally again.
In the event of an EWS complaint, please ask the customer whether the battery had previously been disconnected and whether the fault occurred the first time the ignition was switched on.
2. Please carry out interactive diagnostics on the EWS system using GT1. Move (pull, push, kink, etc.) the line, or wiring harness, during measurement of the EWS ring aerial to the BMS-K(P). Check for overtightened cable ties that may have cut into the wiring harness or otherwise damaged one or more lines.
If you cannot find a fault by means of interactive diagnostics, GT1 will first prompt you to replace the EWS ring aerial. Proceed with the replacement of the EWS ring aerial.
Please do NOT replace the BMS-K(P) or BMS-KP.
