Buying Electrical Bulb & Socket Parts for a 2016 Audi TT
On this vehicle, the bulb and socket system covers every bulb and socket on the vehicle, from headlamps to instrument-cluster illumination.

- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace bulbs in pairs so both sides age together, and put a smear of dielectric grease on the new socket contacts.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions
How many electrical bulb & socket parts fit the 2016 Audi TT?
Our catalog currently lists 41 electrical bulb & socket parts for the 2016 Audi TT across 8 subcategories and 8 brands, covering both the 1.8L L4 Turbocharged and the 2.0L L4 Turbocharged. Each part is matched to the engine(s) it fits.
Do electrical bulb & socket parts differ between 2016 Audi TT engines?
Some do. 24 parts fit every engine; the other 17 are engine-specific. Each row (and the filter at the top) shows which. 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 2016 Audi TT?
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 2016 Audi TT 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 2016 Audi TT?
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.
