Audi A4 TSBs — Technical Service Bulletins by Year
14,245 manufacturer communications are on file with NHTSA for the Audi A4 — service bulletins, service campaigns, warranty extensions, and software updates, 1995 to 2024. Pick a year for its bulletin list.
A TSB is factory repair guidance, not a recall — the repair is not automatically free. For defects and free repairs, see the Audi A4 problem rankings and each year's recall list.
Warranty extensions, campaigns & software updates
The communications worth checking your VIN against — unlike ordinary bulletins, these can mean free or reimbursed work if your vehicle qualifies.
