I seafoamed my JCW (N14) through the PCV hose the other day.

I did 1/3 of a can. Let it sit for 30ish minutes. Turned it on and let it smoke out after some revving. All was gravy and then I took it for a spin. Car felt great.

I figured hey why not do another 1/3 can and flush it more. So I did the same thing, slow pour, let it sit and drove it for a bit.

Car started to feel a little weak and then blam p2885 - limp mode.

Could this be related? What could I have fouled here?

P2885 = Boost Pressure Control Deviation

ECU has detected discrepancy between the expected vs. actual boost pressure. My first suggestion would be to check air intake piping from the filter to the intake manifold, and see if everything is plugged in securely. That and the vacuum lines, especially the ones you touched!

Also, I remember reading people triggering some CE codes after aggressive applications of Seafoam. If you can, reset the light and see if it returns.

Thanks! I am going to check the vacuum system to see if anything came lose or something. I read the p2885 can vary from wastegate, dead turbo, vacuum lines, pressure sensor and temperature sensor. I hope it's something easy. I hate that this code is so general.

You think i'ts possible the PCV line itself became clogged with gunk?

Unfortunately I checked the DV to see if the diaphram ripped. No rip, but I lost the spring in my garage and now ordered the Alta spring so I can't trouble shoot until a week or so :(
