Yet another fuel strip question....

[MWH]

Along with oil this is a "popular" topic I know! 09 GSA single cam for reference.

I've read and followed all the various threads about them. I did try the float conversion with repinning/coding but it didn't really work for me as seemed to get half way then jump about a bit work an unrealistic range. Pinned it back and then tried a Probeemer converter but much the same.

Decided to splash out and get the Spanish fuel sensor as heard lots of positive things about it. But yet again it's not worked for me! I must of killed an Albatross whilst at sea in a previous life.

I fitted it as per instructions but can't calibrate it. The bike has had no fault codes for ages, fitted this and it's come up with 41778: Tank sensor heating element malfunction. It's a code GS911 or Motoscan can't clear so it seems I'm stuffed!

I've checked for continuity from the ECU plugs to the 4 pin connector on the fuel pump unit and they're OK. I'm getting 11.5v at the green with purple trace wire, continuity from the pins passing through the fuel pump unit.

Has anyone else had the 41788 issue and found out what it was/is?

if you recollect all the stuff in all those posts - some find (years back I was also one) if the bike's stuck in a fault condition and having a temper tantrum it won't behave

it should get over itself regardless of the calibration when a functioning strip is plugged in and you try to clear or using the probeemer box (if the tank is only half full) and you clear that fault

then to calibrate the strip must be out of the fuel - the tool (given enough battery support) then goes on some random heat cool cycle for about 4 mins and should report completed

pretty sure 41788 is what I get if I use the motoscan app when its temporarily lost the plot - its the normal fault code that shows up on the 911 too - usually ride 100m (with the probeemer thing) and it gets over-itself so long as the float hasn't been rammed too far on its side stand with a full tank - where it can take a bit longer

I went the float route on my 2007 GSA. Cheap bloke that I am, I purchased a fuel sensor off Ali Express for a Hyundai Sante Fe p/n 94460-0w000 for US$12.30 which has the wires exiting the correct side of the sensor in order to work on the bike. I drew up a mounting plate in CAD to adapt the sensor to the BMW fuel pump assembly and 3D printed it (the adapter allows the float sensor to mount to the standard BMW fuel pump assembly). I reshaped the float rod to match the BMW float assembly and ensured that if did not rub anywhere on the inside of the fuel tank. My 2007 had a ZFE Basic module installed, so I had to replace it with a ZFE High module out of a 2009 GSA (Ebay-US$27) and recoded it with MotoScan based on the instruction for performing the fuel float swap (the ZFE Basic module doesn't display one of the required options that needs to be changed). The fuel gauge now works flawlessly.
