Volkswagen service campaign 24LW

What it saysEngine Control Module (ECM) Software NHTSA’s full summary ↓

Volkswagen filed this with NHTSA as a service campaign dated Feb 13, 2025, received Mar 5, 2025, about the engine — 2 documents under this number: Circular 24LW, Dealer 24LW. It names 1 model year (2025). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Email me new Volkswagen bulletins for the Taos

A weekly email, sent only in a week when Volkswagen files something new with NHTSA for the model you pick — service bulletins, campaigns, warranty extensions, over-the-air notices, every model year. Nothing else is sent; one-click unsubscribe in every message. Separate from recall alerts.

What owners reported

Source: NHTSA complaint database

Owners of the 1 model year this bulletin names have filed 13 complaints with NHTSA since 2015. 3 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Volkswagen 24LW a recall?

No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.

Is the 24LW repair free?

A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

Which vehicles does 24LW cover?

The manufacturer filed it against 1 model year: 2025 Volkswagen Taos. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
