Sorry for the delayed answer - unfortunately I did not get any notification of your post and just saw your reply today. So this DU-EP800 drive unit with production number 7HCUIG668DF is from March 2009 and only has a mileage of 592km. Sure, the W10100 warning wíll be triggered when there is no...

On a DU-EP500, DU-EP600 and DU-EP801 there is definitely NO way to change the derailleur from manual to electronics (Di2) without the cable bound PCE interface from Shimano (and a Windows based computer as well as the Windows based miniMax - program from eMax-Tuning which can do this job already...

@Greg Watts: Pefect words - thank you! (y) Ideally, please create a link to this thread if someone else is interested in the possibilities of any E295 / E299 error triggering or has similar issues.

Exactly. However, E295 and E299 will not only be created by a wrong drive train configuration, but (as written before) can also be triggered by a wrongly placed speed sensor or related magnet. This happens sometimes already at the production cycle and many well-known bike manufacturers have...

@Greg Watts: Thanks a lot - you almost nailed it perfectly. (y) There is only one minor misunderstanding: A wrongly programmed or not programmed (still on the initial value of 3000mm) wheel circumfernce NEVER will cause the E295 and finally fatal E299 errors! A wrongly or non-programmed wheel...

Exactly. Anyone who is buying a brand-new Shimano STePS drive unit should know that the configuration has to be set correctly then, otherwise this will mostly end up in frustration. This configuration process normally cannot be done by any dealer, but only by a very few Shimano employees who...

If you had an E299 which then finally locked your motor, then you definitely have ignored the 4 times E295 which always will occur before any E299! Ignoring an E295 error is quite a bad idea, because you never, ever should ignore any (E295) error on a Shimano STePS based bike and instantly check...

Please never, ever intend to use a "chip" (an additonal electronic hardware - box, also called "dongle" like SpeedBox, MBIQ, BadAss, RedPad, PearTune as well as Planet3 „mechanical tuning“, etc.) on an "EP6 motor" (DU-EP600) because this will definitely not work on the new generation drive units...

Yes, that is true, but mostly the real culprit in such situations on a Shimano STePS system ist the cabling harness between the drive unit and the battery or the contacts of the battery, cabling harness or drive unit. Only in very rare cases the battery or the drive unit itself is the problem...

You are absolutely correct regarding the newer DU-EP801 drive unit ("generation 2") of your bike (see also e.g. this German forum post of a colleague of us with some pictures of a YT bike with DU-EP801)! However, the reported drive unit of @aFox is an older DU-EP800 drive unit type and the...

Thanks for this additional information - however, as written before, please create and post the requested service report! If you are not willing to do so, (at least) I will not be willing to assist further in this issue. You also can connect the (new, "defective") DU-EP800 drive unit solely...

Please use the latest version 5.4.4 of the Windows based E-Tube-Project-Professional software (see here) and create a so called service report via the lower left button in the "MAINTENANCE" view and ideally post this PDF document here to get some overview of the drive unit (and connected...

I completely agree and assume the same. I also assume that the battery nightmare (which I think Canyon managed in a very transparent, reliable and customer-friendly way, even if it took quite long time and many involved owners maybe didn´t see it like that) was quite costly for Canyon in...

I think you should be able to get these (spare-) parts from the German dealership of the "new" YT - headquarter in Germany (again). At least I have listened to these words from the old and new CEO Markus Flossmann in some YouTube interviews with him some weeks ago (should be in one of these)...
