Hard/No Start + EWS msg

My bike has recently (past three days) started having starting issues.

Symptom = stater tries to turn engine over (chug-chug-chug) and then regular start.

Today it did the chug chug thing and wouldn't start. It wasn't like a battery issue, as after 15min it chugged and fired right up.

I read the EWS replacement sticky, no info on why /how this occurs.

Only thing new on the bike is a recent DIY clutch replacement. No external electrical items. Nothing new or different other than the clutch install; bolts on pressure plate were tourqued to spec listed in the DIY clutch install thread.

Any ideas?

Are you actually getting the EWS error on the display?

If so:

1) and your keys are on a key ring with other keys: take the motorcycle key off and use it by it's self .... see if you get the error.

2) Try your spare key see if you get the error ............

3) Got access to GS-911 - if so I'd do error code scan next ...

EWS msg came up after starter kept trying and then stopped.

No other keys on ring...but I have a garage door opener on the ring, that hasn't been giving me trouble. Guess I'll move that and see what happens.

Thanks!

Hm, wonder what your issue was.

Mine didn't start when I tried to leave work. Had to have BMW roadside assistance come and bring it to the dealer. No error message and bike is brand new with ~700 miles.

:(

Had that message several times over the year when my battery was near death and I needed to use a jumpstart. Normally after the 3rd attempt that message came up. I Left the bike for 10 minutes and started the procedure again.

I think that the computers says "stop frying me".

The antenna ring is susceptible to throwing an EWS code at low voltages. I think that is what you are seeing.
See what a GS911 scan says. Could be a marginal antenna ring or the battery is failing.
Good luck.

Similar to Loutre's experience, I got an EWS error after trying to start with a low battery. My culprit was the stator, I'd suspect a charging system issue before the antenna ring .

If chug, chug, chug means the engine is turning over slowly, It sounds like a bad battery. There won't be enough voltage left to the ecu, injectors and fuel pump, for the engine to fire up.

The cause could be a battery, a poor battery connection or the stator is not putting out enough voltage to charge it.

In any case, if you have a weak battery you should replace it because it wears out your starter and alternator (over heating and constant charging, respectively).

Shite battery was the issue.

The kind folks at the dealership replaced it under warranty for free and with no appointment!

Now that batt is warranty covered for two years.

They warned me against jumping the bike directly from an auto (I had done it 3x today)...said cars can fry the ECU and to jump only from a jump box (one of those hand held units I'm guessing).

Also learned today, you can run and bump start an F8. After the third jump of the day (replacing all the air box screws each time...wtf), I managed to stall at a light. It was crazy, and a real mindf#ck cause I never stall! I was lucky I had just crested a hill at a light and tip-toed into the left/u-turn lane, turned around, rolled downhill, popped the clutch and I was off. I always thought the electronics would get in the way of bump starting an F800GS.

All good.

That's two things in one month...hopefully #3 is DIY

I don't know what the danger would be to jump start off a car, as long as the car engine was not running.

I have done car jump starts at temperatures below 20F several times.
No issues. I do use smaller gauge motorcycle jumper cables so that may be safer.

Yeah, I don't know either, that's just what the BMW service rep said.

As far as I know, U.S. cars are 12v.

Car/trucks that did the jump were running for me each time; however, they were not revving the engine. I don't know if engine revving has any effect though, but when jumping cars I do it if I'm having a hard time.

Jumper cable size is not important; just don't start the car as the alternator
output is much too high for a little M/C battery...but always best to wait
awhile, as below:

You can use any sort of wire, even lamp cord to connect a low battery
to a good battery, such as in a car. Don't use the starter after hookup,
but go have a cup of coffee for 20 minutes or more. The good battery will usually
charge the low battery adequately for start up; just remove those little wires before hitting the
start button.....

All this works for good batteries that have been discharged; not for ones that are kaput.
(Multiple batteries that are interconnected will all soon reach the same level, provided they are in good electrical condition)
