Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
Have you checked your coolant and engine oil for any sign of intermix?
Leading evidence: 'Check coolant and engine oil' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check coolant and engine oil' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The same symptoms you described except maybe white smoke should be on BOTH exhaust and not just the right one. One mode of failure of AOS is it sucks the coolant into the throttle body so the coolant burns and appear in the exhaust.
If you're sure the exhaust is only on one side, then it's possible you have a cracked head, which is not common on MkII.
Have you checked your coolant and engine oil for any sign of intermix?
Dropped car at shop. Turned key to unlock the wheel. Notice that oil level shows maximum (it was half full before) and coolant level light comes on. Code shows a misfire.
There was a post a while back in the 997 forum, same symptoms, smoke only on one side ( right exhaust, do you mean passenger side?) engine rattle, ended up being cracked piston...
If it is passenger side exhaust, that means left 1-3 cylinder bank (drivers side). The cooling circuit travels through 1-3 bank first and than gets to 4-6 later so if your water pump lost a blade, it would get stuck in 1-3 bank and end up creating a hot spot and cracking the head... Not sure how much rattle there would be though..
How many miles on your car? Did you have the water pump changed?
Sorry to hear this, hope I'm wrong and that it's just a spark plug that stopped firing...
Keep us posted to what happens next...😥
