2013 E350 Bluetec Engine codes
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?




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.
