What's Lexia ? Where Do I Get It

[stevestoys]

OK guys. I've seen a lot of info relating to Lexia on here. Am I correct in thinking it's a program that goes on a laptop with a lead to connect to my citroen c8 2.2 hdi. ?

Looked on ebay and it's very confusing. Goes on about upgraded none upgraded etc different leads. Anybody have any links where I can get a cheap lead and disc that will check out my parking sensors etc and plug into my citroen c8 2.2 hdi exclusive. Thanks in advance.

Lexia is the computer system used by Citroen dealers when they need to diagnose problems on Citroen cars. There are Chinese clones available on ebay which need to be used in conjunction with a laptop - some clones specifically require Windows XP. Some versions it seems work better than others. Although I haven't used them this company seems to be well regarded. http://www.easydiagnostics.co.uk/#/shop/4590186381/lexia-3-diagbox-for-citroen-peugeot/10015520. Diesel engines didn't become fully compliant until 2004, so any vehicle before that date may not fully work.

The Chinese clones of Lexia 3 all come with the necessary software and cables (OBD2 for the car and USB for the PC) for the C8 (except for a couple of the new Citroens), they are in three qualities:
1- Exact copy with premium components
2- Exact copy with cheap/er components
3- Slightly altered design with reduced component count (cheapest)
 
They all work, some are known to have an issue with Citroen C5, you need to check on the sellers advert or page. They usually say something like serial 921815C and Full Chip (indicating 1 or 2).
Example (this might fall in quality one), you will notice in the description that it works with the Citroen C5:

or this where you need to check if it works with C5

Here you will notice that C5 is not mentioned in the supported cars:

If you need to use one just to check the parking sensors beware there have been reports on here that the cheap copies can corrupt the parking sensor ecu and need it to be reprogrammed. Other ways to check the parking sensors include disconnecting them individually and also listening to each one to see if any make a slight buzzing noise. You can also make sure the sensors are all clean and dry and have not been submerged in water and need drying out.

Actually, Paul.h is right, you can listen to them and the one that does not make the "faint" noise is the faulty one:

Ignition on --> gear in reverse (you can hear the noise inside the car) --> put your ear next to the sensor for 20 seconds (or a sensitive mic)... the one that does not make the (very low) noise is faulty or disconnected...

 

Having said that, I tried removing one only, the car makes a faint noise indication a missing sensor, it did not work. Unless of course the noise you are having now is the faint noise which indicates a sensor is not connected properly!!
