Q5 Faulty DRL

[theblueflash]

A little while ago the drivers side DRL on our 2014 Q5 decided to die. Vcds throws up the 02897 code, supply voltage to led DRL module. The warning pops up on the dis with the ignition on. I disabled the DRLs via the mmi which stops the warning unless you have the lights in auto or turn them on manually.

If you turn them on manually there is a flash then it goes out. Then the warning pops up. I did some digging and a blown fuse or a faulty DRL module is the culprit.
I checked the fuses and none seem bad and I looked in the manual and none seem to be assigned to the drl anyway. Just the headlight in particular and as that still operates on low/high beam I assume that fuse to be fine.
So I moved onto the module. Purchased a new one from Audi, plugged in, flicked the switch, and the same thing happens. Light flashes on for a second, then goes out. Warning pops up on dash.

Question is what else is there to check? The wiring around the immediate area looks in good condition so I don't suspect that. I have exhausted Google and apart from purchasing a replacement headlight I can't see what else to look for.

Any links or advice will be greatly appreciated

As mentioned on your FB post, chances are if you have a new module from Audi that it will need coding. New modules are “virgin” with no coding or parameters loaded and will need a VAG specialist to configure them, and also calibrate if needed.

So I thought I'd sorted this until today. After fitting the new module I cleared the faults and had a look to see if anything was out of place but still didn't work. I left it as it was getting late. Went out the following day and it started working and has been working fine ever since. That was until this morning. Got the warning light and the bulb is out again. This I'm assuming is now an issue elsewhere? Bad earth as suggested? Or is it coding? Which wouldn't make sense as it has been working 'plug and play' without any coding changes. Any suggestions? Cheers

I have exactly the same fault. Drivers side. Will flash briefly when turned on manually Suggesting fuse OK. I can’t even find what fuse it is anyway. Haven’t tried a module yet. Is there also a relay somewhere ?

Had to put it into the garage and they diagnosed the led module itself. That's not the control module but the part that actually emits the light. Unfortunately iirc it's the most expensive part. I'll dig the receipt out tomorrow afternoon for you and double check

Thanks. Would appreciate an idea of cost from garage to determine whether it’s worth having a go myself.

Hi mate. Searched high and low but cannot find the invoice. It's jogged my memory though. I had it diagnosed at a garage. Half hour labour. Bought the part myself as I've got a trade account with TPS and changed it myself.

Sorry. I've had another kid since then and my brain is mush.

Mine was the driver's side which I think has slightly worse access than the passenger side. It probably saved me the hour quoted to change it. Plus getting the part cheaper than retail.

It's not a hard job. Just a little tricky with access

The part is also called a led heatsink. I've googled it as I can't find the receipt but the part was number (7)

I originally changed number (3) but that didn't cure it. I might even have the part still in the garage

Thanks. I have ordered the part. Should arrive Monday. Mine is also O/S. Did you have to take the headlight unit out? Can you get it out without removing bumper?

Don't need to remove the bumper. The headlight moves out of the way enough to get your hand in and around the back to locate and plug it in. Fiddly but once you've worked it out it saves you having to take the bumper off.

Bought the part on eBay £42. Came next day. Very frustrating that headlight almost comes out. Very tricky to get access to remove the old unit. Eventually decided to drop the fibre inner wheel arch. Remove 3 screws fold back enough to give access and changed the unit this way. looking at headlight unit it looked as though you may be able to remove the carrier making it possible to remove completely but screws only accessible from wheel arch. not sure that dropping the bumper would actually help.

Yea. Few options. I did it all from the top. Very awkward but managed in the end.

£42 is a good find. Does it work now then?

Yes all working now. Thanks to you for recognising the faulty unit.
