Hi Friends,

I got very similar problem to the one discussed in this thread.

I have a copy of PSA XS interface which was purchased with 4.3.2 rev B of firmware, I have done succesfull reflash to revision C firmware and current version is 4.3.3 -> there is everything OK. Firmware and interface checker toolset was by Mr. Scarymistake & Majo (Thank you guys!).

Next, I run Diagbox v. 7.64 from mr. Scary as well, this works perfectly too and Diagbox can see when I connect interface to any of USB ports.

But the problem is when I try to connect via this interface to the car (I currently have to solve something on 2007 C4 Picasso w/ Petrol engine), it doesn't detect VIN number and Diagbox within the process of reading fault codes and running "complete test" says "No dialouge" for each unit in the car, so it seems that interface doesn't communicate with car...

Of course, within the attempt to communicate with car relays in PSA interface are clicking. OBD connector in this car works with no problem, I tested this same car either with Delphi DS150E or KTS550 and both systems communicated with car properly.

My PC (or I would rather say WIN os) has no issue in communication with USB PSA interface, I run it on Win XP Pro SP3, it is laptop dedicated for Diagbox only.

Previosly, I tried to connect this interface with 2003 Berlingo or for example ~2005 Jumper and it worked without any problem (including auto detection of VIN and access to all of car units, FAP regeneration, ...).

Attached you can find screenshots from PSA Interface Checker showing version of firmware and "C" revision SN plus screenshots from report with connecting with this car (error in communication with each unit).

Any idea what could be wrong here? I'm getting mad with from interface...

Any help much appreciated.

Thanks and regards, PeterC
