Eyeing a 2012 E350 wagon
I despise SUVs, and not bit into sedans which is the reason my current GTI is the third one in over 12 years, which is the reason I'm eyeing a E350 wagon. I wanted to see if the direct injected E350s suffer from timing chain and carbon deposit issues. These two issues are quite common on the 2.0T engines that are in the GTI to the point were some engines blow at 60k miles due to timing chain having jumped multiple teeth. I'm aware that the new Mercedes aren't the same as the ones from the 80s that you still see driving around but I would like to be able to keep it for 10+ years if possible.




If if you can swing it - keep both! You’ll miss that GTI my friend, I promise you. Not saying the Benz isn’t much nicer, but two totally different cars that are masters at what they do. Perfect combo.
End of the day - I have both for about 80% of what that Toureq was going to cost.

I love the feeling in the morning of trying to decide between driving a Mercedes Benz to work or a GTI. Keeping the GTI was one of the best decisions I’ve ever made!
But to answer your initial question of carbon build up - not a big topic here. Research I found was that these cars don’t have an egr valve (exhaust gas return, I believe) which helps to prevent the carbon from the direct injection. Also read somewhere on here of double variable cam/valve timing to prevent it. Also remember the 2.0 has a turbo. The 350 is a pure 6. Comes in the front, out the back, no recirculating of already cooked air.
These E’s are taxi cabs in Germany. So you can imagine how tough they can be in the grand scheme of Mercedes Benz.
