Our catalog currently lists 33 electrical bulb & socket parts for the 2017 Audi A7 across 7 subcategories and 3 brands, covering both the 2.0L L4 Turbocharged and the 3.0L V6 Supercharged. Each part is matched to the engine(s) it fits.
Do electrical bulb & socket parts differ between 2017 Audi A7 engines?
Yes. Every electrical bulb & socket part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of electrical bulb & socket problems on a 2017 Audi A7?
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 2017 Audi A7 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 2017 Audi A7?
First match the engine — each row shows which engine(s) the part fits. 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.
