FAQ
TL;DR: A Lexia “full chip” clone around ≈ PLN 400 can be a punt; “for four hundred zlotys, it is no problem to be picky.” [Elektroda, Strumien swiadomosci swia, post #16848459]
Why it matters: Shoppers want to know if a budget Lexia clone is usable and what to watch for before diagnosing Peugeots.
Quick Facts
- Street price: ≈ PLN 400 (“4 stówy”) for a budget Lexia/DiagBox interface. [Elektroda, Strumien swiadomosci swia, post #16852174]
- “Full chip” claims often mean only a C‑revision board is loaded, not premium components. [Elektroda, sebap, post #16848607]
- Listing photos don’t verify internals; weak electronics or seals may hide what’s inside. [Elektroda, pepe150, post #16852126]
- Some units have no seals and arrive fully populated, but you must open to confirm. [Elektroda, 3057074, post #16859753]
- Basic IMMO pairing needs the PIN and a “virgin” BSI ready to learn. [Elektroda, szymitsu21, post #16890150]
Is a ~PLN 400 “full chip” Lexia worth buying?
As a low-cost bet, yes—treat it as test-and-return. One user advises documenting with photos and pushing the seller if faulty. This price tier signals compromise, so protect yourself with clear evidence on arrival. Include the price in your risk calculus: ≈ PLN 400. [Elektroda, Strumien swiadomosci swia, post #16852174]
What does “full chip” really mean on clone interfaces?
Sellers often use “full chip” loosely. A member reports it can mean only a C‑revision board is flashed, not enhanced hardware. Expect marketing language rather than guaranteed premium components. “Full chip” here doesn’t certify component quality or coverage. Inspect the board if possible. [Elektroda, sebap, post #16848607]
Do listing photos prove the hardware quality inside?
No. Photos can show anything; the shipped interface may differ. One expert notes you won’t know the electronics grade until you open it, and sellers may use seals to deter that. “On many forums they warn about the weakest versions.” [Elektroda, pepe150, post #16852126]
What if the interface arrives sealed or feels low quality?
Assume risk. A seal can hide sparse or weak electronics. Document unboxing, then test functions you need. If performance is poor, use your evidence for a return. Edge case: you may be unable to verify internals without breaking a seal. [Elektroda, pepe150, post #16852126]
Can I open the interface to verify that all components are populated?
Yes, some units arrive without seals. One buyer opened the case and found every field populated. This is the only reliable way to confirm parts density on a clone tool. Proceed carefully to avoid damage and preserve return options. [Elektroda, 3057074, post #16859753]
Will this Lexia clone handle Peugeot 207, 307, and 407 models?
The buyer’s claim is that it “takes a lot, even the difficult 207 307 407 Peugeots.” Treat that as anecdotal and verify on your vehicle. Test key functions first, such as fault reading and live data. [Elektroda, 3057074, post #16848456]
What can I do with immobilizer (IMMO) using this setup?
You can perform pairing tasks if you have the vehicle PIN and a BSI prepared to learn. Without both, adaptation will fail. Plan your workflow and ensure PIN availability before starting. This is the minimum requirement set. [Elektroda, szymitsu21, post #16890150]
What does a “virgin BSI” mean in this context?
“Virgin” means the BSI is reset and ready to learn new immobilizer data. Once virginized, the module can be taught with the correct PIN. As one expert put it, it must be “able to learn.” [Elektroda, szymitsu21, post #16890285]
Can Lexia/DiagBox edit ECU fuel/ignition maps?
No. A member clarifies that Lexia does not handle ECU map editing. It’s a diagnostic and configuration tool, not a calibration suite. Use dedicated tuning hardware/software for maps. [Elektroda, pepe150, post #16890369]
How do I adapt a second ECU/driver with this tool?
Three-step How-To:
- Obtain the vehicle PIN and prepare the BSI to virgin state.
- Connect Lexia/DiagBox and start the learning/adaptation routine.
- Complete pairing following on-screen prompts, confirming IMMO sync.
Failure to have PIN or virgin BSI blocks adaptation. [Elektroda, szymitsu21, post #16890150]
I used another tool before—can DiagBox add a BSI later?
Yes, users note BSI addition is possible; the key is meeting prerequisites. If you can supply the PIN and have a virgin BSI, DiagBox can learn it during pairing. Prior tooling doesn’t prevent this process. [Elektroda, 3057074, post #16890124]
How should I document and handle a bad unit on arrival?
Photograph everything: packaging, interface exterior, and test failures. Then contact the seller with proof and request a return or replacement. “For 4 stówy, I would not even bother… advertise the seller and after it.” [Elektroda, Strumien swiadomosci swia, post #16852174]
