2003 [03] C3 HDi diagnostic code-reader thing?

Postby nobeard » 12 May 2012, 20:06

Hi people, please excuse my ignorance, but if it's not too simplistic a question could anyone tell me what type/make of diagnostic scanner thing works on a 2003 [03] C3 HDi, to read it's ECU error codes at least?

Thanks

Lexia is the best one, it's what dealers use and Chinese copies are now available for around £130ish

If you just want to read and erase fault codes, and nothing else then buy one of the USB ELM327 cables from eBay. They're only about £15.
I have one and it does that little job just fine.

If you're serious about your C5 ownership then I recommend buying a Lexia so that you can do the complete diagnostics on the car. I bought mine for £85 on eBay recently and it's great.

It's a C3 bud, not a C5.. but would an ELM cable still work? What software would it need?

Yeah the ELM327 would still work. It works on all petrol cars from 2001 onwards and all diesels from 2004 onwards. There's millions of free ODBII software programs you can download, you just have to have a google search.

Er, it's a 2003 bud, i saw that all the 'universal' plug-in code readers only claim to work on diesels from 2004 and later, so that's why i thought i'd better ask about it here.. should i assume that an ELM cable won't work on mine after all then?

Some pre-2004 diesel cars are OBDII compliant. Somebody else here will come along and confirm compliance.

With 2003 diesels its virtually pot luck, some are OBDII compliant, some aren't. ISTR there was someone on here with two almost identical 2003 Picasso 2.0 HDis where a generic code reader would work on one but not the other!

Its not limited to PSA cars either, OBDII code readers work with my mums 2003 Astra CDTi even though they're not supposed to.

According to the list on this website http://www.outilsobdfacile.com/vehicle- ... -obd2.html I think it is compliant.

My early 2003 xsara is OBDII.

The C3 was introduced in 2002 and Citroen knew then that all cars had to comply by 2004 so I wouldn't be surprised if all C3's support OBDII
