Cold start, maybe the glow plugs?

Check O-ring injectors, injector adjustment and pressure at the tandem pump.

Very often the problem of cold start is bad synchronization shaft and camshaft caused by bad installation of the timing belt or its extension. You can check in vcds 01 ENGINE / MEAS. BLOCKS 08 / group1 / Box 4

HI
I think is 01 ENGINE / MEAS. BLOCKS 08 / group4 / Box 4 with values ​​between -6 and +6

HI
I think is 01 ENGINE / MEAS. BLOCKS 08 / group4 / Box 4 with values ​​between -6 and +6

I checked:
-O-ring injectors status OK
- synchronization shaft and camshaft status OK
-timing belt staus OK

is solution to adjustment the pressure injector to start cold in VCDS?
I think this is the solution

Do you have white smoke after starting ?

I do not remember but I think the change in value in 5 block adaptation resulted in the improvement of cold start 1.9 pd. 2.0 may be the same.
