On page 83 my instructions state that the instrument panel runs a test of the instrument and telltale and warning lights when the ignition is switched on, and that during Phase 1 the rev counter and speedometer needles both swing to the limit on their scales. Mine definitely don't do that and never have. Is this the same across the board?
 
Not that it bothers me much, but my needles don't sweep either. It's probably something that is just coded in, so maybe the dealer can do it. I've lost count of the number of Cars I have used VCDS / Vag-Com on to enable needle sweep for people, and I'm like ermmm...yeah.....wow :)

Mines a 2014 GS TE.
 
Does it matter?:nenau

IMHO, it does, because:

1) It puzzled and annoyed me too. I read the owner's manual cover-to-cover before test-riding my bike and, looking at the cluster, failure of the needles to sweep (when the manual specifically stated that they should) was the first thing I noticed.

2) If the manual states that the needles should sweep, that sets a baseline that IT people refer to as 'expected behaviour'.
If the article under discussion then fails to behave as documented, that means one of two things: either the behaviour was modified without the documentation team being told of the change, or the documentation team was informed of the change, but overlooked it.
Either way, it's a cock-up.

Having previously owned an F800GS, F800S and F800ST, I got used to that instrument cluster performing a needle sweep and thought it was a great idea, because it's part of a self-calibration check to verify that the servos which actuate the needles are working properly.
 
bmw are unlikely to reprint all the owner manuals every time something is changed in a firmware update. they are hardly unique in that.

They should. The manual content ends up being misleading if they don't, which in turn does bad mojo to their credibility.

So far, there have been three editions of the LC owners' manual.
Each one has the following to say:

1 October 2012 onward:
When the ignition is switched on the instrument cluster carries out a test of the pointer instruments, warning lights and multifunction display, the "Pre-Ride-Check".
The test is aborted if you start the engine before it completes.
Phase 1:
All warning and indicator lights are switched on. The multifunction display shows all segments. The "General" warning light shows red.
Phase 2:
The general warning light changes from red to yellow.
Phase 3:
The multifunction display and the warning and indicator lights change over to the regular display.

1 August 2013 onward:
Phase 1
The rev. counter and speedometer needles both swing to the limit values on their scales. At the same time, all the warning lights and telltale lights are switched on in succession.
Phase 2
The general warning light changes from yellow to red.
Phase 3
The rev. counter and speedometer needles both swing to the starting position on their scales. At the same time, all the warning lights and telltale lights switched on in the initial phase are switched off in reverse sequence.
If a needle did not move or if a warning light or telltale light did not show: Have the fault rectified as quickly as possible by a specialist workshop, preferably an authorised BMW Motorrad dealer.

1 March 2014 onward:
As per 1 August 2013 onward bikes.

If I made a fuckup like that in my line of work, my supervisors would be looking at pissed-off international customers - which means I'd be looking at disciplinary action at best.
As a major motor manufacturer, BMW should know better than to lean on a cosy little disclaimer like "Changes may be made to specification without notice".

But they all add that disclaimer. You can even find it in their sales brochures. It just means they can take photographs of a bike in Brazil, slap a disclaimer on it, then use the photo in sales literature for western Europe ....... it's not just BMW who do this :augie

I know everyone does it.
But let's look at it this way: the first edition of the manual stated nothing beyond 'a test of the pointer instruments' (which may or may not be taken to mean a sweep of the needles). So far, so good. But the next two editions explicitly read: 'Phase 1: The rev. counter and speedometer needles both swing to the limit values on their scales.'

That means the manual has been at odds with the product for nearly a year (and one version change) at best. Regarding a minor issue, yes. But it's still something a major manufacturer obviously couldn't be arsed to fix, either by tweaking the bike's software or releasing an updated manual when they had a big fat chance staring them in the mug.

Like I said: credibility. Especially when the manual says that if the needles don't move, you should take the bike to a dealer for a check.
One wonders how many customers have done that, and heard "They all do that, Sir." :1/10
 
I think we need a pole to understand just how many people have been daft enough to book their bike in for this 'fault'

I'm really struggling to understand what the problem is.:nenau

I don't need a sweep of the needles to tell me if the speedo is working, or not; I'll soon know once I ride away.:rob
