Oil change, now idles poorly (beginner)

[mcfee03]

UPDATE
Turns out my DISA valve broke, and replacing it fixed the idling. However, the pin is missing, and odb codes as per below.

I bought an inspection camera. Spent hours looking for the DISA PIN, but couldn't find it.

As advised, I removed the intake. Daunting for sure (first time car owner here). I'll be replacing the CCV (as it was entirely cracked).

But the PIN is NOT in the intake!

I took a photo of the valve which looks like it has metal shards. Do you think that could be the pin?

Here is a a video of most of the pins. Does anything look wrong there?

Could any of these ODB faults be related to the PIN?

- Powertrain Faults P1349, P1351, and P1354 "Misfire Cylinder X with fuel cut-off '" (that's' cylinders 4, 5 and 6)

- Error P0102 (MAF low input)

- P0155 (O2 Sensor Heat Circuit).

- Pending fault- P0300 ("Random/multiple cylinder misfire detected").

Hi,

Got my e53 a few weeks ago and been running very smoothly. It's a 2002 e53 X5, with the 3.0l petrol engine.

The previous owner said they hadn't done an oil change in a while. So I thought I'd do it myself as my first "mechanic" task.

I look through a few guides, and followed them pretty much precisely.

1. I took the oil filter cap off
2. The old oil filter was completely saturated with oil (is that bad?)
3. I replaced the rubber ring (lubed it) and the filter.
4. I took off the bolt plug underneath, and about 6 litres of black oil came out
5. I poured 6.5 litres of LL01 5w40 oil in.
6. I started the car for about 30 seconds. I then checked the dipstick. It was filled past the maximum indicator. I then wiped the stick clean, and checked again, but it was not reaching the minimum...

Have I over/under filled my oil?


The car idles very shakey now. Once the revs drop to about 600rpm, it feels as if it will stall. It accelerates differently than before.

the exhaust sounds different. It has an subtle "chug"/ticking noise.

A bit of oil has come out of the flap underneath (not the flap I drained my oil on).

Here is a video, firstly I accurate to 1000rpm. https://drive.google.com/open?id=0Bz...HI0a0QydDVWVnc
