Default Cayenne Diesel Exhaust Leak (EGR Connecting Pipe)

Morning, All! Didn't see any previous mention of this on a quick search, so wanted to drop it here in case anyone else sees similar issues in the future...

FYI: We were getting some exhaust smell in the cabin, especially in cold weather and especially during warm-up. It wasn't so bad that it was undriveable, but it was a noticeable nuisance. We surmised that the issue was on the EGR and--sure enough--it was diagnosed by the dealer as a cracked connecting pipe weld. This is apparently a known issue and reference was made in our repair ticket to "Repair Order 764952". The repair order supposedly references loud engine operation and exhaust fumes in the cabin as a potential sign of the issue, but we were not able to get our hands on the original document. The repair looks pretty straight-forward, and requires the replacement of the following parts (There is some slight variance in parts depending on the MY of your CD. See diagram here for reference: http://www.autoatlanta.com/porsche-p...=95811154720#a )...
  • (1) 958-111-525-01 Connecting Tube
  • (1) 958-107-358-00 Gasket, Heat Exchanger
  • (2) N-911962-01, Pan Head Screw
  • (1) 958-111-547-20, Gasket
  • (1) 958-111-548-05, Clip Connector
Oddly, the repair requires the removal/reinstallation of the Intake Manifold, but the dealer did not replace the intake manifold gaskets as a SOP (seems crazy to me on a nearly 10-y-o vehicle). I would recommend asking the dealer if they are planning to replace these while performing the repair and--if not--purchasing from the parts counter and providing for installation during the repair. Ours is now leaking with an audible whistle when under load and we'll need to bring it back in. (Your parts may vary. See diagram here for reference: http://www.autoatlanta.com/porsche-p...=95811014800#a ), but ours should be as-follows...
  • (6) 95811014710
  • (6) 95811014800
  • (1) 95811014400

Also oddly, the dealer managed not to button everything up well and now we--instead of the livable, minor, infrequent exhaust smell--have a constant, fairly strong exhaust leak needing to be figured out. They also managed to add some wonderful new scratches and swirl marks to our paint and handprints to our headliner during their "complimentary hand wash" which is simply delightful on a vehicle that I personally detailed ~3 weeks earlier ...really justifying that hourly premium for "highly skilled labor", Porsche...

Hope this helps someone in the future!

Was this covered under the dieselgate warranty?

Yes, indeed. Covered as a part of the emissions systems (EGR) covered under the warranty. Given that many are coming toward the tail end of their warranty periods; it may be worth checking the connecting pipe flange for cracks/potential leaks.
