Guys

Iv read so much about the lumpy/judder on a cold start on the forum but there doesn't appear to be an direct solution. Iv found an array of solutions but i'm keen to know in what order would you have each of them looked into?

The last thing I want is to go and fix something only to find its not the fix, so i have listed a few things that could be causing the lumpy judder and wanted to know which would you attack first?

- Injectors
- Glow Plugs
- Air Filter
- Main Thermostat

Last time I had the car checked for fault codes it didn't bring back anything however i do know some diagnostic tools dont always give out all faults

Any views would be good.
