s3 pfl rear diffuser change

[paulo16]

Hi everyone, iv just purchased an s3 on a 65 plate so its pfl, I'm not sure I like the rear diffuser
and looking to maybe put the fl diffuser on would this fit my bumper or do I need to change both?
I may think about doing the rear light change too when I can find the correct loom for the dynamic lights, I know this has been discussed before but only from someone with an s line a3 looking to do fl so I kinda need help with this, or if anyone knows of a good rear diffuser but I kinda like keeping things oem and do prefer the fl rear diffuser, any help would be much appreciated thanks

Hi Paul the FL diffuser will not the fit the FL so you’ll need to change the whole bumper. It’s a straight forward swap so nothing complicated at all. The process for rear light upgrade to the dynamic ones ya the same regardless of your car being a S3 or A3. There is no difference in the lighting wiring loom. You don’t need to buy the adapter as you can modify your existing one and just buy the new connectors.
