Faulty weld seam on the camshaft: a recall, free replacement

critical

On engines built between July and September 2015 the supplier made a mistake in the welding process, so the weld seam on the camshaft is not as it should be. According to the authority's notice the fault affects individual M270 and M274 four-cylinder petrol engines.

Show the rest

On the affected cars the camshaft can break, and in doing so it damages the engine and shuts it off. The engine cannot then be restarted, the car comes to a halt, and in the words of the notice this increases the accident hazard.

As a precaution the maker prescribed replacement of the camshafts. The campaign started in November 2015, the target date for completion was the end of 2016, and the replacement is free for the owner.

At a purchase two things have to be cleared up: does the car fall into the production window, and if so, has the recall been carried out on it. The franchised dealer can answer that from the chassis number.

What to check

  • Check the production date of the engine: the examples from between July and September 2015 are affected
  • Ask whether the recall has been carried out, and ask for proof of it
  • If there is no proof, ask the franchised dealer with the chassis number: they can tell you

7G-Tronic (722.9): mechatronics and conductor plate

expensive

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.
