After years of research and money invested, I would like to share and describe my collection of hardware and software.
4. Actia Multidiag XS 2G (2nd generation), currently with its base program (latest version v2018 43.51), it is a bit slower and the interface not that friendly like Delphi, but it is special because its passthru compatibility. I also use it via Passthru with:
8. VAS5054a and VAG CAN PRO: reflashed modules on VAG. VAS5054a can be used with Xentry Passthru.
Every tool has its capability. For example, I can do full coding on PSA with Launch, I can do coding on Renault/Dacia with Actia, on Passat B8 Bi-TDI i could do function tests on AdBlue only with KTS. Delphi covers pretty much everything.
I would suggest to purchase cheap leads from obdexpress.co.uk instead of trying to use pass through. That way you can use any of the many guides available on the internet. Also I believe the seller is selling the leads with software slightly modified to allow very easy installation.
The thing to note - for E series, earlier cars need pins 7+8 joined, while late E series need pins 7+8 separated. I bought my leads long time ago so I have 2 separate leads, however now you can purchase lead with switch to change this. Also you can use INPA with some F series models, but for that need ENET lead and need to modify a setting in a file. Both leads are available very cheap.
To be continued...
