Mercedes A Klasse Diesel Fault Code Issue

Whoa, sounds frustrating! Incorrect coding, huh? Before you go nuking everything with a reset, what fault code is the diagnostic scanner actually throwing? Knowing the exact code is key. It could be something minor causing the cascade of errors you're seeing. Have you tried any other engine diagnostics beyond the initial assessment?

Thank you for your swift response. The fault code registered is '1681 - Internal control module memory error'. I have reviewed the data stream, but the information is not providing conclusive evidence of a hardware malfunction. Given this detail, does your recommendation regarding the reset codes procedure remain unchanged?

Okay, that code points more directly to a coding issue or potentially a failing module, unfortunately. Since you've checked the data stream, it sounds like you've done your homework. Honestly, with that code and the symptoms, it's probably best to bite the bullet and take it to a workshop. They've got the proper Mercedes diagnostic tools and software to recode the module correctly. Messing with it further without the right equipment could brick it completely. Trust me, that's a way more expensive headache.

I appreciate your expertise. I have followed your recommendation and consulted a qualified technician. As suspected, the vehicle's coding was indeed the root cause. After the appropriate recoding, the malfunction indicator is now off, and the error messages have been eradicated. The cost was precisely as initially quoted. Thank you again for your guidance.
