Car running lumpy when idle and rough

Hi,

Little bit of a back story.

I purchased a E90 320D 2006 as a non runner, no only was the wrong battery in the vehicle it wasn't registered and it then there out two of the modules to start up, cas and DDE. I have rectified those.

I then found that it wasn't running it's best as it would take 3-7 times to start up and the engine to stay running and not cut out. I looked into it and found that the previous owner had put petrol in the tank. There was half a tank of it so as it was running really lumpy unable to build up revs easily I imagine they filled up the tank and when it got to half empty it had issues.

Anyway I have taken all the petrol out, put a new fuel filter on and changed the oil too.

I've taken it out tonight for 150 miles. Whilst it smoked on start up, white smoke but cleared. I'm guessing that's just fuel burning. Anyway for the first 20/30 mins or wasn't the best I had to ride the clutch to get anywhere. When it picked up speed and going on a flat line or down hill it was good. When I put my foot down the engine did vibrate so I guess it's where it wants for fuel but it's struggling.

When I done 30 miles it seemed to pull quite nicely but still lagged up hill, I'd have to shift down and really rag it.

After about 60-70 miles it was absolutely fine. It didn't like being in 6th gear and driven with some acceleration. Sometimes 5th so I was going 4ty gear about 3-4 thousand revs at about 70-80mph.

I ended up doing 150 miles. When idle it's still vibrating the car somewhere moderately. I'm wondering if it's an injector issue or engine mounts. I managed to get a video and a quick error code diag.

Here is a link to the video.

Here is the error log of when starting the car, it did cut out twice as it hasn't been ran for a week.

And here is the error log after the 150 mile run.

Any help would be hugely appreciated.
