Good day everyone,

My car started misfiring giving the codes:

2B48: Combustion misfiring exhaust gas degassing Cyl. 7
2B3B: Misfiring with shutdown Cyl 7.

and on code starts the car makes a weird whining noise kind of sounds like a vacuum and gives a code after the vacuum noise disappears. The code listed below:

27BA: Fuel system LAMBDA / Fullungsplausi - Bank 1

and with another misfiring code

2B48: Combustion misfiring exhaust gas degassing Cyl. 7

Recently done the plugs and coils (also changed the PCV crankcase for the driver side because that was leaking), the car runs fine and no other issues when I clear code but this issue only happens on cold starts.

I just ordered a new air intake temperature sensor to see if that would fix the issue before emptying my wallet, just hoping to see if anyone has a similar issue that knows the fix. I've been reading the forums and still haven't found a conclusion
