My 7yr ELW warranty is expiring this October, and I want to get a final checkup at the dealer.

Wanted to get some feedback on what things I should get checked out. For example, any specific engine / transmission / cooling system concerns for a 2014 507 around 50k miles?

My SA is good with running diagnostics as long as I claim something feels wrong.

Would be good to have checks done in case I sell the car also

Thanks all!

Cam Adjusters are probably noisy, check cams and lifters for wear, look for leaks, especially oil pan upper and lower and valve covers, check engine mounts and PCV are the typical wear items off the top of my head.

Thanks @roadkillrob !

Got it checked out, had an intermittent CEL, came back as stored fault codes for communication errors.

SA says there is no current fault code, but there is a software update available for the control unit.
He said this could be causing the communication errors, but is not sure why it would throw a CEL.

They don't usually update this during regular service, and the charge is $235, even under ELW.

Anyone have an idea on what this control unit update is, and if I should do it?

Are version numbers / changes documented anywhere?

Thanks!

Agree with oil pan.
Upper is leaking on my 2015 with 30k miles !!

My mechanic said you don't wanna know the labor hours for this.... Told me to get it recertified. Called MB this week 😭

Can I look for the oil pan leaks myself?

Anyone other advice from others?

Thanks all!

I've got a 2012 C63 with 61k miles. Had to replace leaking engine mounts (got ECE mounts). Upper and lower pan were leaking. Pads and rotors have to be replaced for the second time in the car's life. intake manifold was leaking. Had a bunch of 02/oxygen sensors go bad that needed to be replaced to pass emissions. Alternator died on me, and battery crapped out.

$6k later my car is running fine though.

When you say intake manifold, are you referring to your gasket or the actual manifold itself?

**** man... mine is 14 with the same mileage... I haven't had any of those issues and I DRIVE mine.

Ok, got the control unit update done and visual inspection came back saying "oil leak around bottom oil pan, recommend add dye and diagnosis"

Advisor said nothing is dripping, its just what they noticed.
I don't have pictures, do I need to lift the car to see it myself?

Also said that after dye is added I would need to drive it for 500miles

Rest of the engine / car is in perfect condition for ~50k odometer.

What do you guys think?

I brought my '14 with 80k miles in for new motor mounts which was covered under the fidelity extended warranty. My friend who is the tech told me the upper pan was starting to show signs of very faint sweating and will get worse. He did say the fix was covered under the warranty but the labor was huge. I dont remember if he said the engine has to come out
