If you plan on owning the bike I would encourage you to get a GS911 there are many of us with lots of experience using them.
However, there is a caveat to this. It can be difficult to translate the technical language of the fault codes to layman's terms. The GS911 people have a forum where one can ask questions, but rarely does an answer arrive. AFAIK
, there is no "list" of fault codes, their meaning or resolution to be found. I would love to be wrong on the above.
When the GS911 gives a fault code, a short description follows, but nothing else.
examples--I got these 3 doing my 18k svc
80401D Tank switch error
This has something to do with the lock on the keyless gas cap
I did find one query about this one with this response from "Wolfgang"
The electronic immobiliser EWS control unit detects a short circuit of the fuel filler cap switch.
The fault is detected if the fuel filler cap switch is continuously operated with the ignition switched off. The control unit input is switched off after 10 minutes
Check wires, wiring harness and plug connectors to the fuel filler cap switch.
Check plug connector wiring harness to the DME.
Check fuel filler cap switch.
Fault effect and breakdown warning The fuel filler cap can no longer be opened.
80402B Preconditions for locking not fulfilled
This has something to do with locking the handlebars, but that's all I can find.
sometimes the description helps
21F761 Oil-level sensor, level too low
Though, does that mean the oil level itself is low or how the sensor reads is too low--I suspect the former since I ran the diagnostics after draining the oil and before refilling. The engine was obviously NOT running.
these appeared during my 18k service check, I reset them, they have not reappeared.
I have not spoken to a dealer about the codes as they have not reappeared, but I don't know if the codes are proprietary to the GS911 or if those are BMW codes. Admittedly I am still a newbie with it, and don't use it very often, have not had the need except for routine service.
I posted my question about the three faults in early November on their forum, complete with the readout from the GS911. Over 110 "views" and no responses. Does no one know or is no one from hexcode monitoring their "support technical" forum?
That said, I recognize its worth. Just being able to reset the service reminder is a huge plus. This is a nice bit of equipment to have if your budget allows, but better documentation and/or a more active user forum would help a lot. Ignorance ain't bliss.
