2013 E350 Bluetec

I keep getting 3 codes they are:

B16BF-15 The left side maker lamp has a malfunction. There is a short circuit to positive or an open circuit.

(Shop scanned it and said I would need a new battery, so we did that. It didn’t help)

All lights and everything works.



B1A4D-14 No code description

I also see under this code N69/5 Keyless go Codes

Sometimes I get a notification on my dash No key detected.

(Shop says replace Aux battery, which helped for about 3 months, then change fob battery, we changed it 6 times)

I’ve googled both issues and I’m not the only one who’s had this issue but no one has posted a solution.

Can anyone help here?

Shop charging you for new battery, when marker light goes bad would not get my business.
The codes not necessary pinpoint the problem and need to be verified by "leg work" and today's technician don't like to walk past the keyboard.
I would advise you to buy your own scanner and bypass the biggest problem you seem to have.
