I've got a MY 2010 with bi- zenons and for some time I have thought that the lights weren't as powerful as they used to be, now I know why the OS bulb appears to have failed, I'll do some checks later (swap left and right) to identify bulb or ballast. I've done a quick search but need to be certain before order up some parts, sources and numbers anyone help? Geoff

Not come across any issues with 09> headlamps yet Geoff! You must be the unlucky one

Beware... Yours either take D2R or D3R and both look identical! BUT the wrong one will NOT work in your light pal

Bit confused - D2x and D3x bulbs are clearly identifiable because the D3x has a built in ignitor?

Also, don't they take xxS bulbs, being projector systems? Visiting from DISCO3.CO.UK

are they not D3S type?

That's what I'd assumed. Are you thinking of D3S vs D3R, Craig? In which case, it should be the 3200lm D3S because it's a projector system. Visiting from DISCO3.CO.UK

So now I am more confused than when I started, also there is no fault showing on the dash but maybe monitoring is switched off. What I'll do is take a bulb out and have a good look for any markings. Geoff

'left to right' swap would be the best bet Geoff...also when you get the bulb out you should be able to confirm what type it is.. ... - .- -.

Letters numbers You know what i meant

Lazy me working from memory!

The point was Geoff, order the correct bulb (if that proves to be duff) as there are several that look the same, but if one number/letter is wrong! They won’t work...

So there was a sticker on the bulb which said amongst lots of other things "D3S 35W E4 OA9 DOT" so I guess that means D3S - doh! next is the left right swap. Geoff

and its the bulb - cheapest? Geoff

Ordered from xenons4u 40quid for two, could have nipped round to Halfords and paid 140 quid for one  Geoff

did you take this opportunety to get 6000k bulbs or did you stick to the OE 4300k ? ... - .- -.

Bulbs arrived both fitted, both working. It's worth noting that although they are very easy to change it pays to be gentle  Geoff
