W205 misfire due to failed inlet pressure sensor!

[GayanC63S]

Hi
I’m driving a 2015 C63S which is currently running close to 81k miles on the clock
I got check engine light but no temp issues or performance issue apart from slight misfire feeling.
Thought it was due to plugs so I changed plugs along with coils as they were on schedule to replace.
Still the scanner showed misfire on cylinder 2. So I took the car to an independent mercedes specialist center and they diagnosed faulty inlet pressure sensor is giving incorrect readings hence that to be changed as the step 1.
I hope this is the only matter as the car is currently undergoing the job as we speak.
The biggest issue is, in order to replace this sensor all the front including intercoolers and throttle bodies must be removed to access it.
I’m just wondering if any of you guys faced a similar situation like mine.

did you get it sorted out in the end? i had a similar issue as well, one coil plug and spark plug later, turns out it was the injector. these low temperatures are really affecting those components that are on their last leg

Hi
Yeah it was the pcv on bank 1. It was chocked and blocked hence the misfire occurred. The first garage took over 7 days after changing sensor for no reason while failing to see this which is very clear to naked eye. You can in this attached image its wet around the area. Somehow 2nd place did a great job within couple of days. This might help someone in future.
