Fault code "0x480687" - what does it mean? Missing clear text information

<< < (2/3) > >>

botus:
cool site - seem to have a bit more info on that code now

480687 Brake pedal travel sensor: Open circuit on ground line dsc_01 Dynamic stability control
Check for break at ground connection of brake pedal travel sensor according to wiring diagram.
Visually inspect connector contacts.

 Other possible fault causes:
- Faulty brake pedal travel sensor
- Faulty DSC control unit

 It is necessary to perform the test module in order to determine the exact cause.


as for entertaining a conversation with a dealer about a fault on your bike and or how diagnostics work is the most ridiculous thing I ever heard...  there are only three out comes in that time wasting scenario

a) its a design feature
b) you're are too stupid to know better than us or to understand anything (but my training means I'm not letting on that's what I'm thinking)
c) this one's brighter than the normal retards, no idea if he's right (where's the check list of how to combat my ignorance with confusing drivel / refer them to the workshop)

e-raser:
Not sure how to proceed with that new information. Everything is working but it feels a bit strange with lots of those error messages.

botus:
the world of canbus and modern software writing can produce unwanted results

a bad connection may send bad info around the systems and or terrible software does stuff it shouldn't - BMW have lots of software updates they can flash to bikes  - it's continuous journey, with up to three normal releases a year

there's a few USA recalls that might be related to your issue for 2020 model year bikes

SIB 34 03 20 to remove a bolt on the mounting bracket they've fitted to cause premature failure of the ABS module for European S1000XRs - it causes vibration issues on the module
SIB 61 02 20 to stop the engine loom to the instrument cluster chaffing and shorting out on the frame (which i expect might put additional data on the canbus) . S1000RR and S1000XR

expect a non USA BMW dealership to be in total ignorance and not believe it when you mention it - the aim of German manufacturers is to treat you with utter disdain and steal your money - resolving under warranty - isn't as profitable as getting you to pay after its run out

e-raser:
I'm going to confront the dealer with it once again shortly.

If it's just a software bug - fine. Do nothing, try a software update or whatever.

In any case I want them to document it in the system. I reported this to them/BMW already last year. If they decide/continue to do nothing, they can't blame me just in case of future damages.

e-raser:
So I brought a printout of the error (GS-911) with me and here's what the dealer said during servicing the bike:

Before the service:
- "There are certain errors which are logged by BMW, but are not critical. Those are often not even reported/shown in our own testers (hidden)."

After the service:
* "There was no error stored/visible." That's also what I got texted on my service report.
* "It could also be that it comes when working the ABS in the control range. The display of the bike does not necessarily have to light up, especially when I brake at the rear wheel in the control range."That second sentence might be true, as I tested it on the way back home from service (I managed to got the ABS working at least on the rear tire, for the front I'm not totally sure) and noted the kilometres.Checked the errors with GS-911 afterwards: no new error logged (no new timestamp), so the error seems to not be related to actual ABS action - and there was no ABS lamp lightning up during testing.

What makes me sad is the first sentence and what I got written in my service report: "No ABS failure stored.". That's simply not true!
The error is still there. It was right before the service (checked with GS-911) and still right after the service (checked again with GS-911). Note: they only reset the service counter during service, did not delete any errors.

So is this really possible? Our "normal" GS-911 devices show errors and the original BMW dealer testers do not? That's
* a) either unbelievable or
* b) really the case that this kind of error doesn't bother BMW so they even hide them for their own garages/dealers.
I don't know what to make out of that. Is it true or does my dealer not care?Anyway, I feel some kind of unsatisfied and tense with the knowledge the bike has this error (even there's no practical impact - so far - on the road).

Maybe I should write an eMail to BMW Munich and ask them if some kind of errors really are hidden from the dealers testers.

Thoughts welcome.
