Do just the DPF's clog? As you know the DPF/DOC is a one-piece unit on the N57. They replaced mine as a "courtesy" replacement ($3k) and when I pressed that I appreciated the courtesy but that in fact it was covered under federal law, they refused to categorize it as a warranty replacement lol. Anyway I digress. They replaced the sensors there too. And the MAF. Waiting now on the EGR warranty availability. We're only $25k deep in warranty work on my N57 since I bought it @ 23k miles. We'll see if the CPO warranty will reach the total price I paid the dealer when I bought the car, before the warranty dies out next April. Can you imagine? That said, killer motor, and once the suspension is fixed drives like a BMW not an Oldsmobile. I have an interim suspension solution, but
@barry@3DM and Ohlins have the F10 on the books to shake out solution far better than the motorsport one - hopefully should be on the shaker rig @ Ohlins some time this year.
Someone needs to come up with an HPFP bypass kit or CP3 downgrade as they do for the trucks. Then I'll bite on the rest.
