which measuring blocks to choose ?

[bmhill]

hi folks

i have a twin cam 2.0 tdi PD DSG 2006 Octavia and it seems to not want to start properly, sometimes its like the battery is flat or the starter motor is lazy for a second or 2 and then it seems like it doesnt want to start for a second and then jumps into life. i have had issues with the EGR and the ant shudder valve/throttle body and have changed both but it seems to be getting worse.
the engine has lag when you press the pedal as if its thinking about things and then it shoots off especially in reverse.
there is what seems to be a miss or something else causing a judder when stationary or moving as if the revs are going up and down but the rev counter stays the same
these bkd engines according to google do this but it can be 1 of 10 things ranging from the injector/heater loom to blockage in the manifold or even vac pipes etc

i am wondering what measuring blocks to log to test from cold start to warm so that may shed some light on things?
any help appreciated guys

These engines suffered terribly with problematic starter motors which resulted in slow cranking.

thanks for the answer

would the slow cranking make it judder and run lumpy?

how would i test the starter to see if its faulty?

cheers

No but potentially faulty glow plugs would.
