Preemptive inspection of the W212 subframe

[MuffinClaw]

Greetings everyone,

I encountered the subframe problem and delved further into it.


I ponder why some vehicles seem to be impacted while others are not; were the subframes manufactured at distinct facilities to varying standards, resulting in a matter of fortunate or unfortunate luck?

I own a 2013 W212 facelift with 100,000 miles, consistently parked outside, and it has no MOT warnings.

Do you believe it is beneficial to have Merc do a visual health assessment? The corrosion seems to begin inside, leading me to question the efficacy of a visible health assessment.

If MB were to inspect it and strike it with a hammer during the inspection, it would be beneficial to ascertain if they would replace it free of charge if it were to fail.
If it fails there, you would need to transport it on a low loader if you want for someone else to do the replacement.

I hear that the inside of the rear subframe may be examined using a bore inspection camera. However, I am sceptical that a Mercedes-Benz dealer would do this service free of charge.

I scheduled a health examination for £30 at MB Hemel Hempstead. It is in two weeks.
These vehicles consistently present concerns!

I own a C250d engine, OM651 model. Do branded oils really provide a distinction?

[DaisyDrift]

Negative. However, the specification does. Ensure the box is labelled MB229.52.

This often occurs soon before to a rupture or fracture.They deteriorate inside; the MOT is only a superficial inspection. Consequently, I regret to assert that a recent MOT offers no assurance. I will paint my item (212 2010) and apply rustproofing to the inside and outside as thoroughly as possible. I own an inexpensive borescope that connects to my phone, which I will use to inspect the inside prior to applying the rust inhibitor, ensuring it is sound and robust. It seems to be in excellent condition externally and has been a vehicle from Kent/Sussex throughout its existence, with little exposure to winter salt in this region.I am optimistic that she will be reliable. I will not be doing the task for a few weeks; however, I will report my results and, possibly, provide photographs of the inside of the frame, contingent upon image quality.
