Since I don't get Polish very well I decided to post it here. Please don't get me wrong if the same thread already exists. I would like to ask which reference should I look in vag com when I connect it to my car. Here is engine ID so if someone can tell me what to use, All 1z, D08 or D09.

all 1z

OK thanks for quick reply....what are D08 and D09?
If it's all 1Z this is timing graph

Another question is: is timing related with car performance or only withengine start (cold start)?

I don't believe tdi timing - reason? If u have a wrong temp sensor results could be incorrect. Always look at numbers

If Injection angle will be less than ~47-55 :
- a little weaker and fuel cunsumption will increase
- problem with start when is cold / smoke :d
- engine's sound will be softer

If Injection angle will be less than ~47-55 :
- a little bit stronger
- engine's sound will be characteristically harder

If u don't have any problems with cold start, power etc. u musn't fix it <ok>

How do I know if the angle is correct? The graph is same when engine is warm enough. Exactly what you said is happening...white smoke when it's cold, "softer sound" and little bit higher fuel consuption

On your ss from vag BS groupe 000 2nd position - 44 is a little bit less from good :] But remember fix injection angle only at warm enginge min 80C at vag because at cold engine injection angle is bigger than warm engine and it decreases with temp. to correctly value.

47-55 is correctly value ;] Do u know how to fix it?
