Hey Gents
I just bought a 2007 t5 2.5 tdi cab chassis BNZ (engine code) off a scrap metal merchant, who had bought if off someone else. He started it briefly but thought the engine was knackered because it was very noisy - so sold it on to me for parts.
First thing I did was check fluids. 5 litres of oil later it idled really nice. Thought I’d fixed it even though the engine warning light was on. At this stage I didn’t notice it blowing any smoke.
I then tried to take it for a drive but quickly noticed it was surging, coughing and the occasional knock whilst trying to accelerate - like the timing was out. I put her straight into reverse and attempted to drive it back up hill into my garage. It wouldn’t rev over say 1200 rpm, but after shutting it off and then back on I managed to get it back up in there. Obviously in limp mode. I noticed it was blowing plenty of smoke and leaking oil when under pressure.
I then bought a Ross Tech cable and it found 2 engine faults. Here is the complete read out
I then replace the Exhaust Pressure Sensor with a new original VW and coded it to the car and also cleaned the Mass Air Flow Sensor with the correct cleaner but nothing changed.
I have added a couple of links to YouTube. One shows the intermittent sound it’s making and the other shows how much smoke it’s blowing.

Any ideas would be greatly appreciated. I’m now leaning towards injector seals but I’m no expert.
