What are the symptoms?
Does it start eventually or is it a total non starter?

Total non starter,
Car appeared to misfire on the motorway one day,the abs and tc light flashed and stayed on while car wen into limp mode. parked up, cane back after work and car started right up but any throttle movement caused white smoke and misfire.
Now it won’t even start, the boy thing that is really unusual is the glow plug lights stay on for a long time, when it’s turning over ever couple seconds it sounds like it wants to go then doesnt.
Iv found water in a plug underneath and to the right of the battery try.
Only thing I’m thinking now is it has shorted out and broken the ecu

The only thing I can see from the photo you’ve attached is that you have a flat tyre and the cars been off the road since 2020.

Also I think iv found my issue, a plug underneath the battery was full of water, I thinks it’s shorted and fried the ecu!
