These are issues documented for the Mercedes-Benz C-Class in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

Yes, due to extreme transmission misbehaviour - one of the most unmistakable symptoms in this library. The transmission suddenly refuses to shift and locks into a single gear (typically 2nd or 3rd), entering limp-home mode. An ignition cycle resets it temporarily, but it recurs quickly with a harsh jolt during gear selection. Very hard for a seller to hide during any meaningful test drive.

Yes, absolutely detectable, but only via a genuine cold start - the symptom is stark and obvious. A standard daytime test drive on an already-warm engine will reveal nothing. Requires a specifically arranged cold start, ideally first thing in the morning before the seller has touched the car, listening for a loud metallic clatter lasting exactly 2-4 seconds. There are usually no dashboard lights at this stage, making the inspector's ears the primary line of defense.
Independent workshops typically charge R24 000-R38 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
Yes, due to performance degradation - this is one of the more buyer-detectable defects in this library. An average driver will notice the car takes significantly longer to crank over and start, and will lack power under acceleration as the ECU enters limp-home protection, accompanied by a Check Engine Light with code P001685. A normal test drive plus a cold start is enough; no special listening technique or equipment is required.
Independent workshops typically charge R25 000-R42 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
Yes, but only via dashboard warnings - this failure wears down quietly, with no unusual sound an average driver would notice. Watch for a persistent Check Engine Light with codes P0016, P0017, P1200 or P1208, and a possible slight stumble at idle. It gives ample dashboard warning before timing skips completely, so a clean pre-purchase OBD scan is meaningful evidence here (unlike the rattle-based Mercedes chain defects, where a clean scan proves little).
Independent workshops typically charge R4 800-R9 700 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
Partially detectable, not reliably. The clearest early warning (a noisy steering lock, or needing to insert/turn the key more than once for the steering to release on startup) only shows up at the exact moment of starting the car - easy for a buyer to miss during a single viewing, and a seller who has already started the car before the buyer arrives will hide it entirely. Ask the seller directly to demonstrate a genuine cold start with the buyer present and listening at the steering column/ignition.
Often genuinely detectable - a misfiring cylinder frequently produces a noticeable rough idle, hesitation, or a felt/heard stumble under load, unlike several other cards in this knowledge base where the underlying defect gives no driving symptom. A pre-purchase OBD scan adds confidence beyond driving impression alone, since an intermittent misfire may not present on every test drive, and confirms exactly which cylinder(s) are affected.
Often genuinely detectable - poor/rough idle, hesitation, or a noticeable loss of power are real, commonly reported symptoms of this failure that an average driver can notice on a test drive, unlike several other cards in this knowledge base where the underlying defect gives no driving symptom. A pre-purchase OBD scan for P2004/P2005/P2006 adds confidence beyond driving impression alone and helps distinguish this specific failure from this engine family's other real, separately-documented causes of rough running.
