Frequently Asked Questions

How many electrical bulb & socket parts fit the 2018 Audi S5?

Our catalog currently lists 24 electrical bulb & socket parts for the 2018 Audi S5 across 12 subcategories and 5 brands, covering both the 3.0L V6 Supercharged and the 3.0L V6 Turbocharged. Each part is matched to the engine(s) it fits.

Do electrical bulb & socket parts differ between 2018 Audi S5 engines?

No. On this page every electrical bulb & socket part fits both the 3.0L V6 Supercharged and the 3.0L V6 Turbocharged. You do not need to pick an engine to choose the right row — use the notes for position and trim.

What are the signs of electrical bulb & socket problems on a 2018 Audi S5?

Common symptoms include a lamp that flickers over bumps, melted or discolored socket plastic, or bulbs that keep failing early on one side. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What should I replace at the same time?

Where labor overlaps, replace bulbs in pairs so both sides age together, and put a smear of dielectric grease on the new socket contacts.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2018 Audi S5 was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2018 Audi S5?

Every part on this page already fits both the 3.0L V6 Supercharged and the 3.0L V6 Turbocharged. Then repeated bulb failure in one position usually means a socket or ground problem, not bad bulbs — replace the socket rather than chase it. The notes column carries position and trim qualifiers where they apply.
