Hello fellow X5 members, I'm been having rough idle problems after the ccv replacement along with SES lights. Before the change the car was running fine and idling super smooth. I notice that I have been getting some white/cream paste on the oil cap and some on the end of the dip stick, so I figure it was a good time to change the CCV and good thing I did too. Once I disconnected the hoses from the CCV, the white/cream paste was running out and the CCV was quite noticeably heavier than the new CCV w/ insulation. After I have put everything back together and started the car, the engine would idle rough, so much that I can feel it in the seat. I would hear some loud ticking sound, guessing it was the DISA unit so I took it off and inspected it, the o-ring around it looks a bit rough so I put some gasket clement on it and let it dry and started it up again. It would idle better but would feel a bit of rumble in the seat still. Took it for a drive and it's fine if I'm pressing on the gas paddle(feels like a bit of a delay, but not sure) but when I come to a complete stop with the brakes pressed the needle would drop down very low like if it's going to stall but doesnt and idles rough for a bit(along with the rumble). SES lights came on and the codes ares
P0300 -
Combustion Misfires Several Cylinders
P1344 - Misfire During Start Cylinder 2
P1352 - Misfire During Start Cylinder 6
P1346 - Misfire During Start Cylinder 3
P1350 - Misfire During Start Cylinder 5
P1342 - Misfire During Start Cylinder 1
I have clear the codes but comes back on after driving for 5-10mins. I have even checked all the hoses and air hoses if they came loose and have no idea whats going on. Maybe I should have just left the CCV alone in the first place?
Anyone got any ideas or experience with this issue??
Thanks in advance.
