Fuel pump controller workaround

I think its useful to point out that in case of suspected failure that the fuel pump does not always make the priming 'whir' when the ignition is switched on.

It will to do so after standing, but if primed once then turning the key off and on again may give the impression the pump is not priming. I have double checked this on another bike now.
 
I just had this problem - left on the side of the road for a few hours before being recovered to the dealer. (should have done my homework!!)

I was told by the dealer that the controller was in short supply! Due it seems to an improved model now being supplied, and the older (dodgy) one being a bit thin on the ground. Bike has been there 2 days now - still no part (old or new type).

Oh Joy!
 
My 2004 R12GS just let me down for the first time in 4 years, just about 80 miles away from home in the middle of nowhere north east of Perth city in the wine region. After a 'brisk' rideout in a group, pulled over and used the killswitch. Reset killswitch after 2 minute break and lots of cranking without firing. Couldn't hear the fuel pump whir, only the ABS self-test.

Waited at the roadside for 4 hours to be recovered by my mate Tony with his trailer. Thanks to the one guy with mobile phone reception who stayed with me until the cavalry arrived (thanks Wayne you're a star).

Got the bike home and jury-rigged a flying lead from a spare 12 volt battery to the fuel pump. Pump spins, engine fires. I can't grumble as its a known fault and I've been too slack to buy an on-bike spare despite knowing the risk of a likely failure.

Gonna buy a couple of spare fuel pump controllers (one as replacement for failed item and one as an on-bike spare) plus a spare ring antenna this week and also make an emergency flying lead using the old pump controller output wire with a BMW mini 12V DIN plug to reach my front accessory socket.

Interesting that there was a bit of moisture/crap under the fuel pump controller despite the previous gasket recall for the blue one.
 
try this guys for that damn controller thingy remve the two torx screws ease out the contoller get some clear silicon bathroom sealer like stuff around the bath anice little bead that follows the outside of oring and carfully refit area must be dry. youwill then have a better chance of keeping the wet stuff out. just bought a 05 gs ther was loads of crud in there what a crap design. Shall I keep the old 1150GS with 16k or flog the the 1200. as they don't seem as well engineered as my trusty old gal that I could wire all sorts of gadgets in. advice please chaps. what else goes wrong to really pee me off.:beer:
 
I have received a response, of sorts, from BuMW Customer Services. They have referred my question to BuMW's Technical Department....

Any response yet?

I'm curently stuck In Khorog, Tajikistan, waiting for parts for a BMW GSA 1200. I believe that the problem is the fuel pump and am told that it's probably the electroninc unit that sits on the top of the pump. A new one is on its way from UK. (two weeks ago) If it does not solve the problem, I'm considering flying the thing to Turkey - the nearest BMW country that may have a computer to diagnose the problem. Anyone know if there's BMW motorcycles in Ankara or is it Istanbul?

The above message was posted on HUBB. I think it's disgusting that BMW hasn't done more to sort this flaw. The disruption to the (hundreds?) of owners that have encountered this problem is so great that pressure should be brought.

Sorted

Was looking at this thread on Wednesday, guess what happened to my 1200RT yesterday, phoning dealer to check they had fuel pump electronic part in stock, luckily they did, so after a drive to pick part up and fitting it, I am back on the road.
Thanks for the information boys and keep up the threads, very helpful.
 
Glad you got it fixed, make yourself a 'get you home' cable for the fuel pump from the old connector just in case.:thumb

In the case of the 'Ring Antenna' (the other achilles heel), the Haynes manual says they need coding to the bike at a dealers. This is total bollox, I proved it by plugging in the spare ring antenna loosely below the handlebars and using the spare key in it whilst starting the bike with the old key in the original ignition switch above the handlebars...... I now carry a spare ring antenna and torx screwdriver just in case.
 
Prob a stupid question,but which side is the FPC on an 06 GSA ?


I'm off to the Alps etc in Sept and will get a spare controller to take with me.

where is it?

Should probably look first..... but where is the Fuel thingy located? The Thread has me worried but don't know where to look!!!

Thanks..in advance

Left side, turn the handlebar fully to do a left turn and it's under your left hand. From memory, all you need to do to get at it is remove the black plastic trim that's held on by a couple of screws and is between the painted plastic and the tank proper.
 
The fuel tank design has changed for the 08 bikes and the fuel pump panel/controller is positioned at a steeper angle (GS's but not GSA's!), still front left of tank, so water should not sit in the recess.

Like wilbjr said, clean the controller heatsink occasionally (small brush) and apply ACF50..........if you don't it could end up like this one and the controller overheat and fail:

I recently updated the 'workaround' (2 versions) page on my site:
R1200GS failed fuel pump controllers
 
worried

about a failure on my 54 plate GS, not being very mechanical my fix had to be simple and easy, now then being a big lad i enjoy the steam pudding and custard,they now come in lovley little plastic tubs so you can microwave them, after enjoying a treagle spunge pudding, I looked at the plastic lid, which is shaped to allow steam out, but it was the perfect size to fit over the housing of the fuel pump and had some nice holes already in it. I just taped this over the top of the plastic cover and now the water runs off it but not into the controller, sprayed some WD40 inside just to be sure. I was out in heavy rain the other day for about an hour, I looked when I got back and the inside of the fuel pump controller was dry, total cost 57 pence for some black tape and another inch on the waist, still the sacrifice was worth it.:D:D
 
FPC Top connectors

OK I have today explored my FPC on my 08 GSA. I have had no problems at all since I bought the bike on 28th May and have covered 6500miles to date in all weather conditions. Mine was clean with the sligthest of oxidisation on the fins. So I have cleaned them up and covered it with ACF 50. What I could not work out (I did not want to damage anything) is how to unplug the small and large conectors that plug in to the top of the FPC. Is it just a matter of pulling them off or what?? Managed to take the caps of the tops to expose the cables but the plugs? Any help gratefully recieved:beerjug:
