Or are D1S and D2R interchangeable?

I thought D1 bulbs use a different plug to the D2 bulb so unless they installed an adapter of some sort how did they managed to install it ?

Edit.

On the far left is a D1S bulb, in the middle is a D2S bulb and next to it is an igniter(adapter) to allow the D2 bulb to be used in a D1 application.

If there is a fault with BOTH headlamps it is likely the car not the lamps .
Yes maybe a bulb isnt seated properly but try and find out what the symptoim is ...

Thanks for your input Clan.
You say the car needs D2R and give hope that bulb type is the problem , but if the two are not interchangeable there is a contradiction; unless you define 'not interchangeable' as Sexton16 : they both fit the car and appear to work but cannot be used in place of one another.
Re symptoms - I'm here as the MOT mechanics could not explain the MOT failure due to headlamp pattern fault to my satisfaction and after being told by Volvo UK that the dealer had said; "...the headlamp beam deflectors are faulty".
I'm no car expert but can still see both HLamp units are as new.

Much appreciate the image Shadeyman.

Yours are deffinatley d2r as your headlights are the same as mine if they have fitted d2s ones then they won't have the masking on the buld to produce the correct beam pattern.

Thanks for that - i'm becoming confident it is the bulbs. In fact my car has D1S currently.

...it transpires Doves the main dealer we bought the car from did initial MOT in 2011 but there were no issues. The local garage failed the car 2012 for "headlamp dazzle" but it seems to have been swept under the carpet by local garage and come to a head again during MOT this year.

At last a proper sympton , headlamp dazzle ! Hopefully it is just the bulbs then but you will need the igniters to go with them .. ( The igniter is integral with D1S bulbs )

...heh I take your point but that symptom you needed only came out as an aside, this morning when I went through documentation looking for info on switching lights to continental setting; by chance we found the 2012 MOT fail sheet.
I now know I was wrong but we thought the symptoms were - local MOT garage said "beam pattern is wrong" and Volvo UK and Doves main dealer have only said "...the headlamp beam deflectors are faulty and can be repaired by replacing the headlamp lamp units with new" and wait for it ..."bulbs not included!"

Becoming an expert at XC headlamp varieties takes time!

thanks for everyone's assistance.

By headlamp beam deflectors I assume they mean the cover that comes down over each bulb when set to dip and lifts when set to main beam? They aren't working?

How could they be faulty on both sides? Surely that would mean another fault somewhere else? Perhaps the headlamps not receiving the signal to drop the covers.

Or does the deflector mean something else?

[blowupp]

Cant answer your questions (i'm just the bill payer :-) but follow your logic.

It was the both sides thing that aroused my suspicion a mistaken conclusion had been drawn - unfortunately Volvo UK just backed up my dealer instead of helping solve the issue ... like you folk hopefully have!

Does your high and low beam work properly? Park infront of your garage and watch the beam pattern on the garage doors when you switch from high to low and back ..

I was thinking the same. If the deflector Volvo are talking about is the actual movable cover then the OP's lights must be on full beam all the time. Could explain the MOT fail for headlight dazzle?

Anyway here is a video to explain it far better than I ever could!
