!LAMPF Error Notification

[RJT89]

Hello Folks,

So, I’m riding along and as it starts turning to dusk, the screen back light comes on. After a short while !LAMPF appears. I’ve worked out that I can clear it for about a minute by flicking on the full beam, obviously when there is no traffic coming towards me. After about a minute it comes back on. I’m certain that when the message appears, my headlight dips to the daylight output. I figured this out because I was getting flashed at by other drivers at night a couple of weeks ago. This is when the problem first came about. It’s strange, because I generally ride all the time with full lights on, including the OEM spotlights and during daylight hours with my screen not lit up like at night time, the message doesn’t appear.

Could the automatic light up of my dash screen be causing power issues with my battery? I have the standard OEM Yuasa battery.

And pointers or thoughts would be greatly appreciated.

The bike in question is a 2015 R1200 GSA LC.

Thanks again.

Isn’t the lampf notification just a blown headlight bulb? I got it in Austria and it was just the dip beam, swapped it with one I was carrying and it was fine

I think it's a front bulb warning, not necessarily blown or headlight - I believe it was on the hexheads anyway.

LAMPF on my R1200GS LC = blown front bulb - dipped beam & pilot once each to date

Yeah it’s not blown. It only appears blown once the error appears. I reset it by switching the full beam on and off. It’s then normal for a minute it so, then the light dims again and the error appears.

Surely if a bulb blows, it shouldn’t be able to come back on and appear normal, albeit a short time and as mentioned only at night when the display lights up when it starts to get dark.

It’s a strange one.

Check the lamp connector is seated properly - sounds like it’s arcing across the three pins… …. It’s showing lampf as it the circuit is being interrupted… it thinks the lamp has blown…

Yep, that’s my next plan of action. I’ll take the display off and double check the connections at the back of the headlight. A friend of mine told me that the other month he went through quite the pothole and it was strong enough to see ever so slightly loosen the rear tail light connection.

Maybe I’ve done the same and it has been knocked?

I used to get this on the HID bulb I had fitted, so I changed to an LED and the problem went away.

I'd change the bulb as the first port of call, see what happens.

I had it intermittently and it was the front indicator.
Waggled it and the fault disappeared.
Indicators get caught when brushing past

Could there be anything interfering with the ambient light sensor?

Otherwise, like others have said, change the HL bulb & see if that sorts it.

Is it a bulb type lamp or LED - the majority were/are LED.

No other way around, it was lamp failure lampF

i spent a very dark and cold morning changing bulbs only to find it was a filament on the rear twin filament bullb that had blown

It's possible, if the bulb has a thermal cut out, normally unlikley on a std headlap bulb though.

do you have bulbs or LED's

Why dont you get off the bike and confirm what lamp is failing, you could be looking at the wrong bulb or LED

 

[Mr Bean]

No other way around

I stand corrected

Yes, you get the same error if you snap a LED indicator off

 

[RJT89]

Thanks for all the responses and suggestions, much appreciated.

I’ve checked all other lights on the bike. No broken indicators or aux lights (both OEM and add on) and no faulty tail lights. Brake lights also are fine.

Is the ambient light sensor in the guts of the of the bike. Maybe I could give that a good clean?

My headlight is the standard OEM LED that was factory fitted to the bike back in 2015.

I would suggest just changing the front bulb, I’ve had a cheapo one which was playing silly buggers all the time, changed it for a quality item and it behaved itself. Start with the simple stuff before you get convinced it’s something more costly

It has been a long time since I had to mess around with headlights on a BMW, but I think that just changing a bulb and turning on the ignition does not clear the LampF error display. On my old F800GS I had to run the bike before error cleared .

The headlight on his bike is an LED unit and it is my understanding can only be replaced as a whole unit - very probably £100's.

 

[squibb34]

The cost of those LED lamp units is simply outrageous, indeed I see many riders have replaced the units one way or another & still get the LAMPF warning.

Anyway I'm starting to think ZFE controller. I think it's tucked away behind the battery on an LC.

Could just be a bad connection or maybe even the fan not cooling the LEDs sufficiently - not something I've needed to get down & dirty with.....yet.
