Is it conceivable to have various error codes but no engine warning light?

[AMG33D]

Has anyone else experienced a 2017 W205 250D coupe with a bitchy drive and low mileage? Is it possible to have no engine warning light but numerous error codes? Since someone else has asked this question and not received a response, I was wondering if there is a known reason why this could happen.

The following P229F85 was shown by the Carly scanner that I used. Nox sensor 2 (in cylinder bank 1) is not working properly.

There is an issue with communication with the control unit 'combustion engine' (U010000).

There seems to be an issue with the control unit 'Multifunction camera' and the U11A300 communication.

There is an issue with the electronic ignition lock's communication (U016887).

This is a B1F4500 warning: the starter battery is too resistive.

The B21059A is a The starting battery's capacity is inadequate. The system or component does not meet the operating conditions.

Communication with the 'combustion engine' control unit is not working properly (U010000).

The control unit 'Traction system' provided plausible data (U041600-).
U010000: The 'combustion engine' control unit is not receiving data properly. The 'combustion engine' control unit is not functioning properly via communication. The 'combustion engine' control unit is not functioning properly, according to the C10000 system.

Please help me understand my rights and responsibilities when dealing with the company and the warranty; otherwise, I may have to return the vehicle.

It is possible, indeed.

There are a lot of codes, some of which may be old, stored in the vehicle.

In most cases, erasing the codes and then seeing which ones return after a week should suffice to ascertain their safety.

Responded from the opposite end. Yes, as mentioned earlier, not all codes produce light in the same way.

Additionally, the MIL lamp will not have been turned on, regardless of the presence of an error code. Faults that are considered to be relevant to emissions are the only ones that need to be lit.

Engine, gearbox, dosing control module, or any other on-board diagnostics (OBD) node or module must be faulty for the problem to be relevant to emissions. Some of those codes and descriptions won't come from an OBD node.

[MrGreedy]

Another possibility exists, and it involves an impending error.
On initial occurrence, the MIL will not be illuminated by certain faults, even if they are emission relevant. For some, the failure must occur over the course of several drive cycles, usually three.

[AMG33D]

Ah, I see! Thank you for clarifying the outstanding code. After fixing those bugs earlier, I suppose I'll just have to wait and see. Only one has made it back thus far.

[AMG33D]

I am grateful. I'll wait a bit before scanning again, since only one of the minor errors has returned so far.

[AMG33D]

Ignore the request for clarification regarding the outstanding code. Thanks once more

I purchased my used 2006 MB with full confidence. I started off by purchasing an iCarSoft scanner. There are no EML warning lights on the dashboard, but there are a plethora of stored 'faults', including one that claimed the vehicle was missing a gearbox.

It has been five years since I cleared the lot, and nobody has returned.

[AMG33D]

wow! I'm just giving it enough time and will be driving it over the weekend to rescan and see what's wrong; getting the responses has cleared my mind for now, haha. The only light that came back was about a communication issue, but it was marked as minor.
