W205 M274 C Class

[Mario6806]

Any ideas how reliable is the Australian W205 M274 2.0L turbo engine compared to the US versions? I have a 2014 C class with 95K and so far I have changed the crankshaft position sensor and nothing else apart from spark plugs and oil changes, Does anyone know what else could be waiting for me in the future so i can be prepared and start searching youtube?

Like almost all modern engines it is the electronics that let it down. Generally I would of said the M274 was a good engine.

Forget about those 15,000k oil changes.
8-10,000K's at the maximum.
Even my stealer Service manager advises this.
Keep an eye on the plastic engine parts.

As John points out, the electronics let the contemporary cars down.

My W212 wagon is at an independent shop as I type this. A transmission module has been sent off to ECU repair in Sydney.
A faulty component in on the Transmission Control unit was sending false signals out on the Canbus causing all sorts of bogus error codes.
Only MB Xentry could pin this particular problem down.
The bill will be $3200 plus for the repair.
This is on a 12 year old car with only 75,000k's on the clock.
