i don't think you're doing anything wrong , i haven't had a 2018 VW Crafter for a diagnosis yet but for sure the older years (2008-2014 0 would link up to the ecu through LT3 tab since they are using a different protocol or something ( never was sure about it either ). Maybe the VCDS doesn't have a ROD file for that vehicle yet ? Maybe the boss will help us both understand this problem

just a small type error, its actually a 2017 model, sorry about that

JMR · Feb 24, 2022

now you seem to have a problem with your number 4 injector ? There was a problem with the number 3 also, which one did you change ?

brucevdm · Feb 24, 2022

hereis the values on injectors, so the 1 injector was around the 40 number which was number 2 so we replaced it and now their all the same

yea i saw that now, not sure whats going on, if i rev it to around 1600rpm then there is no misfire, just on idle and to around 1400rpm the van shakes slightly

JMR · Feb 24, 2022

well here the thing: i am speaking now from another side of the road as this procedure is done on Mercedes Benz , newer than 2013 Sprinter model , 2.1 liter. After injector change on that specific model some adaptations need to be run for the injection system to calibrate the injection rate, injection pump speed, injection quantity valve . I've done few of them after injector change, piston repairs and engine swaps. NOW i am not sure if some sort of this procedure applies to the newer model of Crafter vans. So maybe you need a adaptation/calibration/learning of injection system or just writing the injector codes should be ok on this model ? As i've not had the pleasure to work on one of this, i defer to more informed people on this matter , surely i'd like to be prepared to take the right action should the need arise in the future on this matter

I was thinking the same, and i looked at some videos on people coding 1.6 tdi vw injectors and then doing an "adaptation" called "IDE02637 adaptation for metering quantity measurement" but this only gives me a value that i can type in and the current value is number 4 so not sure what i need to do on this, at basic settings there is IDE02703 reset learned values quant meter unit and press contr valve" i did this but still same misfire around 1400rpm and lower, smooth engine above this

usually when injectors are changed , it should be fitted with new O rings, and nozzle fire washers which helps for perfect fit of the injector . I am not sure of this new type of injectors ( not sure if they are the same like the older ones because there was some talk around here that on newer T6 i think there are some sort of returnless injectors or something if i remember right )

Yea new injector came with new oring and new seal on it

brucevdm · Feb 25, 2022

Morning guys, any feedback yet?

JMR · Feb 25, 2022

have you tried to erase codes and see if any come back ?

brucevdm · Feb 26, 2022

JMR said:

Yes either number 3 or number 4 cylinder fault code comes back

JMR · Feb 26, 2022

bummer, can't think of anything right now

. Could you post a screenshot of your injectors compensation rates ?

Well, I don't know what the values indicate but compared with another engine (below) they seem to be very far away from each others - cyl 1 & 2 are (minus) –86 µs, and cyl 3& 4 are +87 µs.

Below a snippet from a log from an engine 04L-906-056-KN (Transporter T6) on idle after two hour drive. The samples are taken approx. one/minute (time stamps on top row hh:mm:ss).

Over the two hour drive they averaged as follows (132 samples, sampled at one minute intervals). Under load the values seemed to converge to zero.

Fuel injection time deviation: cylinder 2	0.227273

yea so they were something like this before the injector has been changed and swopped over to get them all the same, i have no idea what they mean either but they are now similar and not like this where the one was -40

Uwe told you that in the very first post. I am thinking that maybe injector 3 is not mounted right / torqued to spec

doubt thats the problem because the injector comes with a new seal installed already and there is 1 bolt that holds down injector 3 and 4 with the same bracket, all torqued correctly

Just wanted to provide feedback on this, bent con-rod caused the issues

2018 VW crafter tdi biturbo slight misfire between 1000 to 1400rpm
