Thanks for the Code 11 = Battery, I couldn’t find that. We will “ride on” and I’m not too stressed because it’s running great again as usual. Even has a new plug and cleaned tank and injector. That said I will be pursuing how to clear (or fix) that code 🤨 and I will report.

2014 Like 200i w/ 1600 miles. Was thrilled to see this post! Started running rough for no apparent reason. Started thinking bad gas bec we had used some gas from a questionable source. I then put some Techron in and after a couple days, it died completely. I pulled the injector line and pumped out all the gas. Put in fresh and it would start but not run off idle. Pulled the injector and watched it spray. I had never done that before but thought it seemed pretty weak. Should that injector spray a nice strong atomized fan? Also, one other symptom was when running on the center stand at part throttle, it would backfire out the exhaust. Kind of a weezy pop. I always thought that was a lean condition. Going to check that in-tank line asap but not with the scoot for another week so trying to line up my options. Thinking the Techron finished off the bad fuel line… Thanks, C

Update- Fixed! My wife had a rotten fuel line! The one on the pump. In our case, it didn’t look too bad but when I squeezed it, fuel poured out all along its length. Had a piece of 5/16” fuel injection hose on the shelf and it fit perfectly. My only advice is don’t be afraid to cut it sufficiently short so it doesn’t stress the pump in the bracket. I took mine apart and cut it back twice 😌. Runs like a champ! Thanks so much for this post!

Update II- I’m back with the same problem. 2014 200i running rough and then died and wouldn’t start. Throwing a CLEP code 6. Decided to re-visit the in-tank fuel pump and line. I had replaced this line with something I had on hand. I was pretty sure it was fuel line that I used but here we are one year later. The line I installed had completely failed. It didn’t disintegrate in pieces but the outer layer swelled and split open. I need to make sure I’m using the proper line that can withstand that environment. It’s back running like a champ again.

Edit- I have gone down the rabbit hole of “submersible” fuel line. I just received 12” of 5/16” Dayco submersible fuel line from Summit Racing. I will be installing it tomorrow and I expect this problem to be behind me. Also, I suspect the original line in my tank was not the proper specification or maybe was poor quality. “Submersible” indicates that special material is used on the outside layer as well as the inside layer. Standard fuel line uses special materials only on the inside. That’s what I’ve learned in the last week after many parts shop visits and time on the internet. C.
