I have just brought the car on Saturday. Brought a milltek last night and am looking for some LED rear lights. Do they void the warranty for after market mods?
It wouldn't surprise me if they voided a claim but it might depend on the Dealer. I wouldn't worry about the lights though.
Some dealers may say all mods void warranty regardless of whether they may have aggravated a failure whereas others may be more sensible about causality.
With visually apparent mods I guess it may increase suspicion and further investigation.
What year is the car? I'm guessing an earlier model as you want to fit LED rears
