FAQ
TL;DR: For PSA vehicles ≤2010 use Lexia/PP2000; newer need Diagbox; "newer cars are Diagbox." Install Diagbox 7.44 for coverage. [Elektroda, grala1, post #17533100]
Why it matters: This helps beginners pick the right PSA diagnostic tool and safely change BSI features like auto door locking.
Quick Facts
- Coverage: Lexia/PP2000 typically fits ≤2010 models, while Diagbox is required for newer PSA vehicles. [Elektroda, grala1, post #17533100]
- Licensing: Lexia and Diagbox are paid; many online downloads are pirated and risky. [Elektroda, pepe150, post #17534132]
- Manual auto-lock toggle: If a central-lock button exists, hold it 5–10 seconds with the engine running. [Elektroda, pepe150, post #17534132]
- BSI telecoding path: Run Global Test, enter BSI, then Telecoding (“TELECIFICATION”); sometimes pick Repair first; save Visualisation. [Elektroda, grala1, post #17536973]
- BSI swap/cloning: Requires EEPROM transfer by soldering/programming (PIN, VIN, keys, mileage), not OBD alone. [Elektroda, dziungwaj, post #17547066]
Which is better for a beginner: Lexia/PP2000 or Diagbox?
There isn't a single "better" choice. Use Lexia/PP2000 for vehicles around 2010 and older, and Diagbox for newer models. As one expert put it, "You will not diagnose newer Lexia or PP2000 cars." Start with Diagbox if you need coverage for recent PSA cars. [Elektroda, grala1, post #17533100]
Will Lexia/PP2000 diagnose a 2011 Citrobn C5?
No. For a 2011 C5, use Diagbox. Lexia/PP2000 suits about 2010 and earlier PSA models. [Elektroda, grala1, post #17533100]
Are Lexia and Diagbox free to use?
No. Both are paid programs. Downloads you find on the internet are pirated versions and may be unsafe. [Elektroda, pepe150, post #17534132]
How do I enable automatic door locking on a Citrobn Berlingo?
Do it in the BSI via Diagbox telecoding.
How-To:
- Start Diagbox, select your brand and vehicle, and run Global Test.
- Enter BSI, choose Repair if required, then select Telecoding ( TELECIFICATION ).
- Find Automatic Door Locking and set the desired state, then confirm.
Save a Visualisation before changes to revert if needed. [Elektroda, grala1, post #17536973]
I don't have a lock button; can I still enable auto-lock?
Yes. Without the button, enable or disable auto-lock by changing the BSI configuration in Diagbox. [Elektroda, pepe150, post #17536133]
In Diagbox 7.44, why do two windows open (Scantool and Lexia)?
This can happen when you connect. Diagbox 7.44 may present both Scantool and a Lexia window. Continue using the module shown and proceed carefully. [Elektroda, elektronikq, post #17547044]
Where exactly in Diagbox is the door-locking option?
After Global Test, enter the BSI module. Choose Telecoding ( TELECIFICATION ); if needed, pick Repair first to unlock Telecoding. Then browse BSI configuration for locking features. Take a Visualisation screenshot before changes. [Elektroda, grala1, post #17536973]
What is a Global Test and should I run it first?
Global Test initiates communication with all control units in the car. Run it first to detect modules and avoid misconfiguration. Then enter BSI from the results list to telecode features. [Elektroda, grala1, post #17536973]
Is updating Diagbox from 7.01 to newer worth it?
Updates primarily add support for newer cars. For older models, updates often change nothing in practice. Avoid update mania if you only service cars like the 307. [Elektroda, grala1, post #17533100]
Can I transfer data from one BSI to another with software only?
No. To clone a BSI, you must move or program its EEPROM. That chip holds the PIN, VIN, key data, and mileage. Soldering or chip programming is required. [Elektroda, dziungwaj, post #17547066]
What if I change the wrong BSI setting?
You may disable features or cause unexpected behavior. Before editing, open Visualisation and capture screenshots of current settings. That lets you restore factory behavior if needed. [Elektroda, grala1, post #17536973]
Which software should I use for a 2010 Peugeot 307?
Use Lexia/PP2000. For cars around 2010 and older, Lexia/PP2000 is sufficient. Newer vehicles require Diagbox instead. [Elektroda, grala1, post #17533100]
How do I toggle auto-lock without a diagnostic tool?
If the car has a lock button, hold it 510 seconds with the engine running. A confirmation message should appear on the display. If there is no button, use BSI configuration. [Elektroda, pepe150, post #17534132]
