I've just recently acquired a Fabia Mk4 Colour edition- latest 2023 version with the new rear light cluster design.  I always like to have a spare set of brake/rear light bulbs. Can anyone tell me what type they are  - ie 380 or 382 ??  Trying to find out on line using my reg number doesn't work for some reason.  

Sorry no idea, you might have to look on the bulb holder of the light units, numbers are now usually P something for incandescent bulbs now, e.g. 382 = P21W, 380 = P21/5W.

 

Unless you buy "heavy duty" or a good make at a good price, standard replacement incandescent bulbs can be crap and need testing before fitting as they may not work out of the box or fail because of storage vibration if kept in the car.

 

I've found the VW computer program can be very sensitive and put up the amber triangle of doom for a bub that seems fine yet not indicate for one clearly off colour - but perhaps the German computer engineers have resolved this by 2022.

 

If you find out report back please for future reference of others.
