Credov's researched list of the 2 faults the Mercedes-Benz C 180 is known for (2005–2006), 2 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: On a stone-cold start, listen for a 1-3 second rattle from the front of the engine, then feel for rough idle.
Why it matters: In the worst case the valve timing shifts enough for the valves to hit the pistons, and Australian owners report repair bills around A$10,000 when the fault was left until damage was done.
What to look for: Start the car several times from cold and hot, feeling for any delay, click or pause before it fires.
Why it matters: A failed ESL can leave the car needing a tow with no warning, and the repair - a new ESL coded to the car, sometimes with the ignition switch - is a few hundred to over a thousand dollars.
