2.4 V6 Timing/New Pump fitted

[Gary_Belcher]

Hi all I just fitted a new vp44 pump. Car starts and idles. But really underpowered!

I'm trying to check timing can anyone confirm the correct way. I did get some videos from vcds

Thanks for any help/advice.

(Edit 2.5 v6 TDI 180)

Sorry, didn't have time... go into the TDI timing checker and select the BAU engine. I put a new pump on our 2005 4B AKE engined AllRoad a few weeks back and it was a long time since I had done one so I had to brush up my knowledge





Dynamically checking and adjusting commencement of injection




Special tools and workshop equipment required











t
Socket 3078




t
Fault reader











t
Torque wrench -V.A.G 1331- (5...50 Nm)




The commencement of injection must always be checked after renewing the toothed belt or loosening the injection pump bolts or toothed belt sprockets, and adjusted if necessary.




–
Read measured value block “function 08”, Display group 07, engine running at idling speed.




–
Check readout in display zone 4 (coolant temperature).




l
Specification: at least 85 °C




Do not continue the test until the coolant has reached the specified temperature.




–
Start basic setting “function 04”, Display group 04, engine running at idling speed.




–
Check display in display zone 4.




l
Specification: 100%




–
Observe display in display zone 2.




l
Specification: “retarded”




–
Check display in display zone 3.




l
Specification: 2° ATDC ± 2°




If specification is not obtained:




–
Switch off ignition.




–
Remove toothed belt covers (front left and right).











–
Check toothed belt tension.




l
The marks -1- should be aligned.




If the marks are not aligned:




–
Tension toothed belt.




–
Slacken nut on belt tensioner using special tool.











–
Turn Allen key anti-clockwise until markings -1- are in line, then tighten nut.




–
Tightening torque: 36 Nm




If the toothed belt tension is OK (markings are in line):











–
Slacken camshaft sprocket securing bolts -1-.




–
Apply ring spanner (22 mm) to pump shaft and turn slightly:




l
In direction A ⇒ to retard commencement of injection




l
In direction B ⇒ to advance commencement of injection


Note


Do NOT loosen nut -2- for injection pump sprocket. Otherwise this would alter the basic setting of the injection pump. The setting cannot be re-adjusted with workshop equipment.











–
Re-tighten camshaft sprocket securing bolts -1-.




–
Tightening torque: 20 Nm




–
Check commencement of injection again and compare with the specification.




If commencement of injection is outside specified range:




–
Correct setting at injection pump sprocket (re-position toothed belt).




–
Install toothed belt cover.

I'm struggling with this. I'm just not sure what I aiming for! I did make an adjustment to see what vcds does but I think I made it worse.

2.5 v6 adjusted timing. worse? - YouTube (https://youtu.be/bRbavlQn4F4)
