Had one fail today so I'm going to do the mod and fit the 20w bulbs. Will these be ok and not throw the code on the dash?

Yup! It will. I replaced mine with a similar bulb from Halfrauds last year. All I had to do was file one of the pins of the bulb's cup and Bob's your uncle, Fanny's your aunt. No errors, no smoke. Slightly brighter, but never as bright as a newer car with LED DRLs, so don't build up your expectations. Just sayin'

What bulbs did you buy - I bought some
233 T4Ws and they threw the code on the dash.
 
My E90 has Xenons and one of the bulbs had gone. I just "mullered" the old one to get it out of the fitting, then filed a couple of slots in the fitting to get the new bulb in. It was one I had in a spare bulb set and didn't throw a fault.

But I think you can buy "non-CANBUS" bulbs that are supposed to prevent fault codes. :thumbsup:

At the time I remember experimenting with different led bulbs of different shapes, sizes, number of leds and prices. No one was as bright as the 20 watt above. I guess it's as important how the light bounces inside once fitted as the net brightness of the bulb.
 
I'm watching this with interest. One of mine failed recently so I went through the process of googling LEDs or brighter incandescent bulbs. The results of my research were that all LEDs seem to result in a warning lamp on the dash that needs to be coded out without offering more light than the OEM 10W bulb, and that 20W incandescent lamps melt the bulb holder fairly rapidly. As such, I just replaced the failed 10W bulb with one of the same rating. Also, if you're careful, you can wriggle the dead bulb out of the expensive BMW bulb holder without damaging either, then wriggle the new lamp in. No modification of either is required :)
Impressively, I've had my Zed over ten years and use the sidelights for every journey, yet this is the first lamp I've had to replace anywhere in the car.
