COM2005 Delphi random lights

[saskak]

Hi all,

Now I know it is a berlingoforum, but I have a Berlingo (M59) and a Peugeot 307. They share so many things that I thought someone might know a solution.

So, the indicator stalk in the Peugeot 307 if you wiggle it slightly it turns the headlights ON. This happens if everything is switched off and sometimes from potholes or normal travel they switch on again. Turning the sidelights ON cancels this random switching altogether. So, if the sidelights are ON, this never happens.

I know it is a known fault with the DAV COM2000 and the floppy indicator stalk that one can easily sort with a new plastic plunger that gets worn. So, I took it apart, and the COM2000 unit is Delphi COM2005, not the DAV one. The plunger is a new type, not as round and they have changed the ground plug (airbag) with a screw. I could not find a single fault, cleaned the connections, etc. Just to be on the safe side, I ordered two new plungers and replaced them. None of the old ones were worn out. I believe that the ECU cannot recognise some sort of command from the COM2005 and the safe option is to turn the headlights ON. It could well be that there is some cross touching of the really fine contacts in the indicator stalk, but they seemed alright, nothing was worn or touching something else.

Nevertheless, this random switching of the headlights is still happening. Does anyone know what causes this in the newer Delphi COM2005? I am temped to get a second hand unit (£30 or so from ebay) and replace it and hope for the best kind of thing.

Many thanks again and apologies for the car not being a Berlingo :-)

I suspect that the COM2000 in the newer M59s are the same type. I have not taken my M59 COM2000 apart to see if it is the same, but both are the same year 2007, so I guess they are.

One last thing, there are no Auto options on the stalks, so it is not some option that I have forgotten to switch off/on.

Also, forgot to say that in the COM2005 they have replaced the indicator stalk ribbons with proper wires and a clip, so it is not that the ribbon is somewhat damaged as with other COM2000 units.

My thought is that its a fault in the stalk not the coms unit, probably the twist function for the lights.

Yes, that was the other option, that the twist thing is somewhat faulty. There is a person on ebay that fixes them for £40, but I wanted to have a go myself before sending it to someone.

You used to be able to get replacement stalks from china but god knows what the quality was like.

You have probably seen this video but I thought I would post it up nonetheless.

This is a Delphi.

Yeah thanks, I've seen that, but he did not really do much to it, only clean and re-assemble. I wonder if I can take apart the stalk itself apart and inspect the connections/mechanism. I have not seen anyone taking these apart.

I can't say I've ever seen a stalk disassembled either.

They must come apart somehow you would think.

Found one blog that shows the process and perhaps the fault (https://ajcreatif.com/car_peugeot_206_in...stalk.html). It seems to be a simple pull the end cap off, squeeze the plastic in the middle and the end part pulls off.

Miraculously, my stalk seems to have repaired itself. Just made a few trips and no matter how much I wiggle the stalk it does not turn the lights on. I will test drive it tomorrow as well. I suspect the fault will come back again, so I will try to take it apart to see if I can conjure some sort of a fix. Will report back if I do something.

Good hunting finding the blog.

Isn't that just like it...the stalk knows you are going to have a go so it behaves.

I'm sure you will be able to fix it, you appear to be a very resourceful chap.
