Follow rickyboobys advice and you will piss away $$$$, They will take $160, then list $thousands of parts to replace and you will be no closer to REALLY knowing your issue.
Having said that, BMW has multiple parts warranties for some parts. Depends on what is wrong with your car.
Oh, don't bother 'wiping out' the 'carbon build up'.... Your issue is almost surely not that.

Which is why I suggested he go to the dealer - diagnosing the complex emissions system and multiple components that fail by saying what "P" code he is throwing is going to get him nowhere
If you buy a BMW out of warranty and especially a BMW diesel you need to be prepared to do two things:
1) Spend a good amount of money at a independent BMW mechanic or alternatively the dealer if you trust them, to keep the emissions system working and intact as there are multiple components that will fail at some point or multiple times
or
2) Deletes
Since OP is sticking with keeping everything intact, he needs to be prepared to pay for proper diagnostics, and component replacement costs - yes some parts will be goodwilled, and yes I'm aware the Federal Emissions warranty is EXTREMELY limited, however, the CARB warranty is helpful to him, if his components qualify - (there is a gray area I read where he needs to need emissions testing in order to qualify for it)
I did post this above as well in a later post on the thread, since you only really read my first response -

Either way, a diagnostic fee is only charged when the work isn't being done by the dealer to reimburse for their time, I recommend he go to the dealer, have them diagnose the problem properly, and fix it (which is likely one of the EGR valve) properly, and be prepared to have random things in the emissions system that need to be fixed properly in his ownership -
I was lucky enough that my wifes 2013 CPO still had factory warranty for about 8 months, and boy did it come in handy, between 42k when we picked it up it needed the following a week later:
-both NOX sensors replaced (those are pricey)
-Power steering pump (that was a WOW) considering the miles, with deflection/idler pulley)
-Transmission sealing sleeve (tech said it was leaking)
2 months later CEL back on and no issues driving, take to dealer and its throwing SCR efficiency code so the following was ordered and replaced under warranty as it took a month to come in-
-SCR Catalyst (another pricey item)
I have the service records from the first owner of her car, both DEF tanks and metering nozzles and sensors were replaced at 35k as well.
