What is the volvo part number for this stupid bulb?

[erikv11]

Great summary info from mrBrian. JKL bulbs from Mouser is the way to go, I wouldn't roll the dice with generic eBay bulbs unless you get more info on manufacturer. Get a handful of 'em.

Not sure why the link to the JKL radio bulbs is being butchered, I will try again: https://www.mouser.com/ProductDetail/JK ... juen1ys%3d

That is volvo part number 9166336.

The ECC bulb is: 9454848 and is a much longer bulb. Well the bulb itself is probably the same but the socket is much longer on the 9454848.

Please note that if you look on FCPEuro, you can find part number 9166336 but it cross references with the ECC bulb number of 9454848.
I had a email chat with them and they said their records show both part numbers as being appropriate for the MCC but I do not believe that is true. They don't have a picture of the bulb so I don't know which one you'd get if you ordered that part number from them.

I tried to use the longer bulb and it literally doesn't fit. The MCC control unit isn't deep enough for the longer 9454848.

Since europarts is a sponsor here I'll link to the parts:
The MCC one you want (9166336) : https://www.eeuroparts.com/Parts/56902/ ... BJEALw_wcB

The ECC bulb you don't want (9454848): https://www.eeuroparts.com/Parts/88625/ ... x6EALw_wcB


I'm posting both links so people can see the dramatic difference in the length of the bulbs.

The bad news is you can see the cost isn't much different online.

Another issue is it seems as if the contacts of the bulb itself is soldered/welded to the base of the socket so replacement of just the bulb isn't trivial. I mean it should be doable but it might take some working so that the socket isn't damaged as there isn't a lot of working room around the socket base.

Thanks I really appreciate the help. And yeah this is shorter than the other one because I had picked up some of the longer ones from the junkyard thinking they might fit and they are physically too long from the ECC to fit the Mcc

I found and fit same bulbs from B4 Passat instrument cluster, fits my 1999 Volvo V70 manual climate control panel and works. They are 12V 2W and socket type BX8.4D.

I bought some BX8.4D bulbs from a local store but they did not fit my MCC unit. I have ordered a bunch of aliexpress instead. Not sure the will fit either.
