What it saysLubricating engine components before reassembly. NHTSA’s full summary ↓
Volkswagen filed this with NHTSA as a manufacturer communication dated Jun 18, 2026, received Aug 6, 2024, about the engine — 2 documents under this number. It names 68 model years (2016–2026). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 68 model years this bulletin names have filed 7,398 complaints with NHTSA since 2015. 1,835 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.
On the 2019 Volkswagen Golf / GTI, the 145 owners who gave an odometer reading for Engine reported it at a median of 500 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The plastic oil pan at the bottom of the engine of my 2019 Volkswagen Tiguan 2.0t started leaking while I was on the highway, nearly stranding my family. It was very disappointing to see any vehicle using a fragile, unprotected plastic oil pan at the bottom of the engine, especially the Tiguan, which is marketed as a sport utility vehicle

After noticing an oil leak and blue smoke in my 23 VW atlas, I took it to my local dealership in Tupelo, MS. I realized there was an open recall for the PCV Valve / Oil separator under code 10LP. However, the bad PCV valve also caused the timing chain cover to go bad. The dealership called me back and said VW would not cover this issue.

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 579.5Is Volkswagen TT 10-18-02_2 a recall?
No. A manufacturer communication 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 TT 10-18-02_2 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Volkswagen warranty extension on file lists the ones Volkswagen has filed.
Which vehicles does TT 10-18-02_2 cover?
The manufacturer filed it against 68 model years: 2023 Volkswagen Arteon, 2022 Volkswagen Arteon, 2021 Volkswagen Arteon, 2020 Volkswagen Arteon, 2019 Volkswagen Arteon, 2026 Volkswagen Atlas and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
