LED festoon C5W bulbs

**kodkod.84** · 16-01-2011,12:36 PM

The road salt has taken it's toll on the crappy numberplate housings on the A4 and I have to replace both units and bulbs due to disintegration.

Now I have tried ZiZi LED bulbs but these throw the bulb out error, so I have put them in the Golf with no troubles.

Anyone know of a make/model LED bulb that are a straight plug n play in the B7 A4 with no resistor harnessing or the like?

Cheers

These should work. I don't get any errors with them: http://cgi.ebay.co.uk/Xtec-C5W-LED-E...-/370253946590

Scott- I gave these a try and also trigger the bulb out warning on my A4- I guess the VW system doesn't have the bulb out warning system as LED bulbs work in my MK5 Golf.

These bulbs are now for sale here:

Plus side I got brand new bulb housings from the Audi dealer which were quite reasonable at £16 for the pair.

Hmm, that's an odd one. My VW definitely has the bulb out warning, as I've seen it. Can't really think why those bulbs wouldn't work.

I think it's down to the type of OBD system used in the b7 A4 as I have seen people use these LEDs in the b6 A4 with no problems. If anyone has fitted resistors to overcome the problem and can show me a how to would be much appreciated

I have to fit a resistor next weekend to get round a number plate bulb out caused by the led light in the camera I fitted. Will do a how to but can tell you now, the tailgate has to come apart. I will do a guide.
