I was driving along today no problems, gave the van a bit of a boot to get past a van and the orange diff lock warning light started flashing.
Van drives no different as I can tell.
Had a look underneath and all looks clean and good around the diff and haldex.
Turned ignition back on and light still present.
There’s is a similar post that was never resolved and the user hasn’t been on for over a year hence the new post.
I’m going to do a vcds scan tomorrow, but as I’m in the mountains of the Basque region it’s a little worrying.
Does anyone have any idea what causes this light to come on?

There’s is a similar post that was never resolved and the user hasn’t been on for over a year hence the new post. That’s because its locked up.

Perhaps a sudden change in temperature set it off but the electronic experts on here will soon be on the case I am sure with a better idea.
 
Are you referring to this previous thread....... Diff Lock Flashing Light Problem

It looks like he is still active in the forum
No it was this thread Diff Lock Warning Light
The one above is interesting and it didn’t come up on my search.
I guess I need to scan it. The cable is buried so I’ll do it in the morning and post a scan. Maybe clearing the fault will sort it. Hopefully a blip from putting my foot down.
Thanks
 
So this morning the warning light isn't illuminated. Wonder if it got too hot yesterday going over the mountains.
Also,I had VW do the Haldex service at about 100k. It now seems highly likely that they didn't change or clean the filter so this filter will have 139k of crap in it.
That's job for when I get home as the Haldex service is due again anyway.
Here is a full scan just now.
Ignore all the headlight schizzle I've gone LED everywhere.

I think that even if they did clean and change Haldex oil filter ect that at an additional 39,000miles it is well over due mine was filthy at a much lower mileage from new and was causing problems.
 
So a little update. After the fault had self cleared the other day, whilst driving along later the diff lock warning light started flickering like mad then going off then flickering etc until it became permanently illuminated again.
Just checked the van, which has been parked up for a coupe of days and light still on.
I’ll scan and clear again before I move off again.
Given the way the light activated I’m thinking wiring issue.
