Citroen Synergie fault code reading?

My Bro-in-law has a 1996 Citroen Synergie 2.0 LX (petrol) which he says is running very poor. Before I take a look I was wondering if it is possible to pull any stored fault codes on this model or does it need to
be hooked up to specialist equipment. I've had a look at Autodata CD and it gives the procedure to manually access any stored codes using the homemade flash LED method but looking around the net I see there are 2 types of DLC on the Synergie, one with a 30 pin (which is the one described on Autodata) and also a 16 pin. Anyone know if the 1996 Synergie codes can be read using the LED method?

Why not find the DLC and count the number of pins?
I haven't yet come across a surefire way of telling what parts are fitted to any specific peugeot/citroen car. My local motor factors assure me that they can tell me from the registration number and have on more than one occasion supplied me with the wrong part.
They just seem to use what was lying around the factory at the time. Usually on the peugeot/citroen cars I have experience of, I have to remove the part I want to replace and take it with me, or at least have a good look at it on the car before I buy a replacement.

If it has a green 2 pin SD connector in the engine compartment, the chances are that you can. If it has the 30 pin connector fitted in the passenger compartment, codes can only be read with a dedicated FCR. Mike.

I had a 98 1.9TD SX . The ODB plug was under the dash on the right near the bonnet catch puller. You might be better posting this query to the forums on www.andyspares.com
If you define what running poor is you might get some pointers from people here. It is running lumpy , not idling fast enough , too fast , tapping , knocking etc etc
A dealer will want £50 for a code reading, so I'd cover all the basics first i.e. plugs, leads , coil resistance , breather pipes etc

Yes, I've now had a look and it has a 30 pin plug under the dash. Tried the LED method connecting to pins C2 & C3 but the light remained permanently lit. I was looking in Halfords and their Citroen/Peugeot Draper code readers don't mention the Synergie or 806 so looks like it needs the proper gizmo tool. Incidently, them Drapers are a complete rip off. I had a look inside the box thinking that they at least contained the correct fitting plug but they're nothing more than the homemade version.
Does anyone know if the Synergie check engine (MIL) light should come on when you switch on the ignition because I noticed that this does not come on, or does it only illuminate when it registers a fault?

Will do thanks.

It idles at about the right RPM but sounds lumpy and if you very lightly open the throtle the revs will drop before picking up, or sometimes when you release the throttle the revs will drop to almost stall before levelling out again and sometimes will stall. Seems fine and runs ok on an open road but in traffic there is an occasional engine splutter and misfire and the Temp gauge goes high. He's had a new thermostat and temp sensor fitted but made no difference to the gauge reading. I'm sure there were other things he mentioned but I can't remember now.

Will do, ta

Maybe you missed my earlier post. Unless it has the green 2 pin SD connector under the bonnet, you need a dedicated FCR to extract codes. You can't read flash codes from the 30 pin socket using a simple LED setup. All you can do without an FCR is to clear all the codes, by disconnecting the battery for a couple of minutes. However it is an adaptive system, (learning capability) so any previously set values will be reset to the default setting. Also of course the radio memory and code will have to be reentered.

The light should come on when the ignition is switched on. It should go off as soon as the engine starts, unless there is a fault. Should also come on if a fault develops while you're driving. Mike.

Thanks for that. I did notice a 6 pin connector near to the battery (not sure what colour) but didn't see any 2 pin, but there may well have been which I didn't notice.

That's what I thought. Any bets on there being a bulb in place if I remove the instrument panel!

You won't find one on your car. They have either a green 2 pin SD connector under the bonnet, *or* a 30 pin one under the dash. You've found a 30 pin one. Hence no 2 pin SD connector under the bonnet. Dunno what the 6 pin one is for. Mike.
