Volkswagen service campaign 37U2
Volkswagen filed this with NHTSA as a service campaign dated Dec 20, 2024, received Jan 7, 2025, about the engine — 2 documents under this number: Circular 37U2, Dealer 37U2. It names 1 model year (2024). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationVehicles included in this action may have been built with incorrect settings in the Transmission Control Module (TCM) which results in the Start / Stop system not working correctly. A disabled Start / Stop system will increase engine idle time while vehicle is stationary, however, the vehicle emissions remain within certified tailpipe standards.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volkswagen 37U2 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 37U2 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 37U2 cover?
The manufacturer filed it against 1 model year: 2024 Volkswagen Tiguan. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
