Cat query about obd ?

12th July 2012, 19:29

Ok so i seen some sites with cheap cats quality prob shit but only plan to be on car for a couple of months as just needs to pass mot then will put a cat replacement pipe on.

So mine is a 97 VTS with centre cat but my query is about obd am i right in assuming mine has no obd ?

12th July 2012, 22:00

If you mean on board diagnostics then every saxo no matter what year has it mate.

13th July 2012, 14:14

Yeah thats is what i meant thanks for letting me know i need one with it, so why do they sell ones without obd that seems kind of pointless what use would it be as i assume the obd reports to ecu and throws up eml if not there of course im just guessing so may be completely wrong ?

13th July 2012, 16:17

Well kind because you plug a scanner into the obd port to retrieve the fault code/s.All saxo`s have the port yours is located under the dash(passenger side)near the fusebox.

13th July 2012, 19:43

Yeah i undertstand that as on the veccy you used to be able to do a wire trick to read the fault codes.

So i suppose one without obd would not register to the ecu i guess ?

Heres the cats im referring to

As you can see both the ones for mine are no obd which is why i asked the question as i cant seem to find one with obd for my car ?

Can anyone hell with this ?

16th July 2012, 16:27

Mate google bosal exhausts you`ll have more luck on that website because they supply citroen with their oem exhausts.Or buy a used one off here.

The later saxos (3 plug ECU) run a second lambda after the cat.

So it reads to me
"none OBD" is no second lambda
"OBD" with second lambda

I think that site complicates things, try my guy across the road from me

No harm in asking i guess but im wodering about this lamda i plan on getting this out at the weekend to see if there any tell tale signs of it being knackered as dont really just wanna buy stuff for the sake of it now if only you could buy a cheap machine to measure your emissions life would be easier lol

shame your working weekdays dude as im free (not sat/sun though), id be more than happy to help/lend you my axle stands/tools.

Im more than sure your more than capable of doing it but if you want help just ask buddy

GeeDawg,

Your '97 VTS will have a single plug ECU, the generic fault code readers off ebay won't work on your model, the only thing that'll work for the DIY code reader is a Lexia3 circa £80.

I think there was an EU mandate which was agreed by all manufacturers to have a fault code system (OBD), first appearing in '96 then a more universal OBDII in 2001 - or something like that. Wiki will have the lowdown on it.

What it means is > 2001 Saxo's can have a basic level of fault code reading on a bog standard universal reader. < 2001 saxos are a bit odd. I don't believe I've heard of anyone successfully reading the codes from universal reader (I have a 2002 model and I originally bought a ELM327 code reader from a chap who had a 2000 saxo and couldn't use the system. That said it was crap on my car so I just plumped for the Lexia3). The Lexia3 is a a copy of the code reader systems used by Peugeot/Citroen - which has a lot more functionality, diagnostics and testing procedures.

EDIT: so in answer to your question... Try it and see where you get. The plug is on left hand side of the passenger side, there's a rectangular bit in the dash towards the bottom. Pop that out, and you'll see the connector and fuse box.

I tried it on my 51 plate 3 plug ecu and it works, only had 1 fault though.

Your Lexia3 sounds damn good. My mate is a top mechanic at Citroen Slough so any real probs i ask him.

18th July 2012, 00:54

Sorry, it's late and I confused you with the Original Poster.

Lexia3 is good, great even, especially with 3 cars at the house which can use it. But Citroen mechanic wins hands down I think!

Its a good investment i suppose but i can get a second hand cat and lambda for that cost and would a machine like this tell me if the lambda or cat are fucked its just a thought as salas may tell me something if thats the case ?
