UPDATE: I finally bought my own GCU cable to update the firmware (£115 from Velo-Store France), seeing as the firmware and installer package and instructions are now available on the Mahle website (
https://mahle-smartbike.com/firmware-update/).
I ran the update on my Ribble CGR-ALe and in a couple minutes the firmwares had been updated, from the My Smartbike app the Joystick controller is now
iM2EM126 (was iM2EM101), the battery controller is now
51 (was 45) and the iWOC controller stayed the same at
4701 (that's supposed to happen according to Mahle)
. The Pulsar One now seems to work correctly. Success!
My wife's Ribble Hybrid AL-e suffers from the pink flashing 903 error every time it's charged up to %100 and the firmware update is supposed to fix this so I tried it. The first time I ran the update (carefully following the instructions on the website) only the Joystick controller firmware was updated so I ran the update again as it explains on the website. During the update something went wrong and the iWOC light turned hard pink and stayed there, the bike has gone into
'Safe Mode'. I checked the pen drive used in the update and it wouldn't read in my laptop/PC, I checked the GCU cable and it was completely dead (no indicator lights showing when plugged into the PSU)! The cable is going back for a refund.
I've now taken the bike to my local Mahle dealer who with the help of Mahle is trying to get the bike going again with no luck so far. He managed to get it out of Safe Mode but the motor didn't work.
I have to say that Mahle have been pretty helpful trying to sort out the problem, sending me instructions on how to fix it etc but I'd already taken it to the shop by then. The bike shop asked me for proof of purchase from Ribble to check warranty status but I don't know what that means, it's probably out of warrant by now?
Thinking this is going to cost me money...
