2 important faults

On the transverse M260 and longitudinal M264 four cylinder petrol engines the valve seat or the valve guide wears early. The symptom: check engine light, rough running, misfire on one or more cylinders. Sometimes without any fault code being stored.

Show the rest

According to the maker's official service bulletin (LI01.30-P-072328) the valve seat leaks. After the leak test, if a leak is found at the valves, the whole cylinder head has to be replaced: the valve seat cannot be refurbished. The roller width of the intake and exhaust side followers differs, and swapping them is prohibited.

In the United States the maker announced a 15 year / 150,000 mile (about 240,000 km) extended emissions warranty for the M260 group (MY2019 to 2022 A / CLA / GLA / GLB). Outside the United States that programme does not apply automatically, but the fault is the same mechanism. The GLB 250, the CLA 250 and the A 220 use this engine.

between 40,000 and 150,000 km

What to check

  • Ask for a fault code read: misfire codes of the P0300 / P030x kind and mixture formation codes are suspect
  • On a cold start watch for rough running and the check engine light
  • Ask whether the cylinder head has already been replaced: according to the service bulletin that is the repair, not valve lapping

In the Mercedes 7 speed 722.9 automatic (7G-Tronic / 7G-Tronic Plus) the mechatronics unit and the conductor plate (Leiterplatte) age over time: jerking on shifts, delayed engagement, a "Getriebe schützen" message, and fault codes on the gearbox electronics.

Show the rest

The repair is typically replacing the mechatronics unit or the conductor plate together with an oil change: not the whole gearbox. The complaint is most common on the longitudinal platforms from around 2005 to 2015 (C/E/ML and the early GLC).

The 9G-Tronic (725.0) is a different design; this applies only to the 7G.

between 100,000 and 220,000 km

What to check

  • Try it cold and warm: a delayed 1 to 2 or 2 to 3 shift is suspect
  • Watch for the gearbox warning or the "Getriebe schützen" message on the dash
  • Ask for a fault code read on the gearbox controller (not just the engine codes)

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
