Possible Problems for Certain AMG Four-Cylinder Engines

Pretty much everybody loves the M133 four-cylinder powerplant powering the A 45 AMG, CLA 45 AMG and the GLA 45 AMG, right?
Everything, from the performance blend between cylinder displacement and overall power and torque to the fact that it can be made to sound like a WRC engine with the Performance Exhaust option, makes the M133 one of the most fabulous four-cylinder engines in recent decades.

With that being said, you should probably take the following information with a grain of salt, despite the fact that the source makes it look pretty plausible.

According to an email received by a Mercedes-Benz A 45 AMG customers from AMG themselves, a total of 365 cars that use the M133 engine will be impacted by a service measure to check the twin-scroll turbocharger.

If necessary, the turbocharger in those cars may be replaced because of a residual contamination of the oil feed line, something which may result in loss of engine power or even damage to the turbocharger itself.

Apparently, only cars built until February 2014 may be affected by the problem, but we don't yet know if both the A 45 AMG and the CLA 45 models may suffer from the same problem.

According to the email's content, only one turbocharger failure on an A 45 AMG has happened until now, with the customer having had his entire engine replaced because of it, but Mercedes-AMG mention the fact that they are confident it was just an isolated incident.

In other words, we shouldn't worry about a large recall so far, at least until we find out more details about the problem and maybe even from an official source. Most info above comes from a personal email which we have decided not to publish without the receiver's consent. We will keep you posted if anything else regarding this matter pops up.
