Spent all day on it again!
Lumpy idle on warmup
While I was working on it I thought I'd check the fuel flap actually works and found quite a bit of pressure buildup in the tank, it was running low so I filled up to around half a tank.
It seems to pull spot on but after a few mins lumpy idle.
Starts on the first click of the motor!
Any suggestions?
Pressure in the tank is very bad, I'd get that looked at.
If it was vacuum, it's sometimes a case where the fuel has been removed and the air just needs to be drawn in, to replace the fuel. The tank cap should take care of this but might possibly be problematic.

I am having the same problem with mine which is a 06 SDI had it read on the machine and comes up misfire detected on cylinder 3 not sure if it's the injector or the loom
Just bought some of that rhino fuel treatment to see if it will clean the fuel system up, you get enough for another car so my Passat is getting the same treatment
They will generate a pressure in the thank if the level is low.
Try removing the fuel filter and checking the fuel in the housing .if it has oil in it then possible tandem pump issue. Also if there is fuel in housing then look to change injector seals as they are a common problem on of engines.
It's got 3/4 of a tank, serviced it the other day with no oil in the filter housing just dirty fuel (as I expected with no service history for 4 years!)
Ran on crap supermarket fuel too.
If the additive don't clear it, I'll look at getting the seals done
