I made a little research on
http://www.chinahanji.com/25_elect4.htm
In fact, the information is from Bosch site but with all injectors together.
Now I don't know what properties of an injector make's it compatible with another. I tried to filter using the type
If I have PDE-P1.1/80/520S216 038130073BA, I have this:
bosch code type original code car engine code
0 414 720 216 PDE-P1.1/80/520S216 038130073BA Passat 1.9 TDI Variant/ Alhambra 1.9 TDI AVF/ AWX/ ASZ
0 414 720 222 PDE-P1.1/80/520S222 038130073BC Passat 2.0 TDI
0 414 720 225 PDE-P1.1/80/560S225 07Z130073K Touareg 5.0 TDI
0 414 720 228 PDE-P1.1/80/560S228 070130073N
0 414 720 229 PDE-P1.1/80/550/229 038130073BJ
You can see that the ARL ones are not compatible, are P1.3 (don't know what it means but for sure there is something different in the ECU, you cannot mount them without modifications).
0 414 720 039 PDE-P1.3/80/550S39 038130073AL GOLF IV ARL
So, it seems that the Touareg 5.0 and 2.5 TDI injectors should be ok and the biggest OEM, but we don't know about the nozzles, if they have the same spray angle, 150*. No info about that.
The 073BJ have the same nozzles as 073AL ? Can those 2 be fitted to BA injectors?
