The EA839 is not the same in the Macan, it's in the S4, SQ5 etc and has ring failures it seems. I'm not sure if the forged bottom end in the 2.9L variant has these issues, but there are serious issues with the S4/SQ5 platform. I have a buddy who dropped cylinder 4 and 5 just recently. Tuned ones have a tendency to drop #6. Call any local audi shop and ask them what they think of the EA839.
Edit: Here's some info form 034;
Their tune in particular seems to pop #6.
No offense but why would a BMW forum be an accurate source for Audi engine information?
The EA839 first went into Macans in 2019. That's 5+ years ago. There have been virtually no reported issues with that engine on here on Rennlist.
No offense taken. My response? So? Are you saying that unless it’s off a certified Porsche site it doesn’t matter? 😂
No, I am saying a BMW forum is not ideal, nor representative, of Audi information. And here on an actual Porsche Forum, the largest in the world, there have been zero EA839 issues reported.
A few, and I mean a few, early Audi cars had rocker issues. Nothing since then. Other problem all seem to stem from tunes or poor maintenance. The EA839 is solid.

You are writing of faults that don't exist.
Im not writing of any faults. And what makes you think because information regarding a Porsche engine posted on BMW forum should be dismissed? Really?

If youre not trying to point out faults, why did you bring it up in the first place?
I stand corrected, mea culpa. 3.0/3.6TTV6 cold vee and 3.0SCV6 cold vee are not variants of the same engine with different induction types.
In this thread there has been no VAG documentation provided to substantiate technical specifications or naming convention for the 3.0/3.6TTV6 cold vee.
Non-VAG and therefore not credible sources refer to Mxx naming convention for the 3.0/3.6TTV6 cold vee. VAG documentation is given below for the EA837 3.0SCV6 cold vee and EA839 3.0T/2.9TTV6 hot vee engines.
In summary: avoid the 3.0/3.6TTV6 cold vee engine like the plague. The EA839 3.0T/2.9TTV6 hot vee is proving itself to be robust.
3.0/3.6TTV6 cold vee and 3.0SCV6 cold vee use bedplate blocks. 3.0T/2.9TTV6 hot vee use more robust deep skirt blocks.
Porsche 3.0TTV6 cold vee:
EA837 3.0SCV6 cold vee
From VAG SSP 624 for the EA837 3.0SCV6 cold vee. No such document has been provided in this thread for the 3.0/3.6TTV6 cold vee engine.
EA839 SSP 655 . Pay close attention to "mono-turbo and biturbo" statement. This relates to the 3.0T and 2.9TT hot vee variants.
Porsche also lists different approved oils for the Macan 3.0/3.6L (A40) compared to the EA837 (C30), which is further evidence that there are meaningful differences between these engines.

On the other hand, VAG recommends C20 for EA839 3.0T and C30 for EA839 2.9TT and C40 for EA825 4.0TT in Cayenne installations. EA839 2.9TT has the highest bmep of the three Cayenne EA engine variants. Oil spec is inconclusive.
A Self Study document, as the two examples posted above, or other VAG-published document is conclusive. All else is guesswork.
I think we (as a group) still without a final answer. So far the Macan 3.6TT is the EA837 or M4635? Based on the information above looks like the M4635. If is the M4XXX, how good is this engine. Obviously I dont want to run everyday like in Nürburgring, but sometime is needed. The cayman engine looks more robust and ready for hard work than the Macan.
The Cayman is sold now Im looking for the next toy. Now Im driving my crazy Land Rover LR3
