A couple of weeks ago, a warning light came on in the instrument panel of my Octy and a message in the Maxi-Dot display saying "faulty DRL" (or words to that effect).

I checked and the offside front DRL was not working. Assumed bulb had blown, but couldn't see how to change it (the manual isn't much help either).

A few days later, fault had cleared: offside DLR working again, so obviously bulb wasn't the problem.

Now I get the same warning, only this time it's the nearside DRL that isn't working.

Appears to be an electrical or computer fault. Anyone else experienced this?

I'm loathe to waste half a day at the dealers as I had a similar intermittent fault with the aircon which they couldn't diagnose (it's mostly worked fine, but on a couple of occasions it wouldn't provide cold air until I had turned off the ignition and re-started, effectively "rebooting" the system. No, it didn't need a coolant recharge!)

And how do you withdraw the fog light cluster from the bumper to change a DLR bulb if that is the problem??

UPDATE: warning light on dash, but both DRLs working again. Oh well.

Warranty job.
