it does not smoke when engine warm or accelerating
only when starting first time or if left for a few hours

full diag on engine done and no issues seen


- What i will do in next few days is take it back to garage and get him to provide readings with the vac pipe connected
- I will also disconnect the MAF and advise of any issues

- new EGR due for delivery next week so once fitted will check again

Vortex was changed by me but i have checked it and it is all sealed and fitted with no leaks

Good feedback!
Smoke only when it starts or cold ,could be leaking injector , assuming glow plugs are fine!Could be oil accumulation somewhere,also!
You must have the egr vac connected and egr fully functioning before any diagnostics are carried out as if its disconnected it will give you incorrect readings,on MAF ,for example!
The ECU will look for a loss of air pressure when EGR is activated and if its disconnected ,this loss of air pressure obviously isnt present and hence the wrong readings.
Keep us posted
