2021 Volkswagen Tiguan: fire, smoke or burning smell

Filed Aug 25, 2026 · Engine · CA

Noticed the check engine oil light started coming on periodically between oil changes 3-4 years ago, but no external or noticeable oil leaks. Was told by VW multiple times it’s standard for VWs to burn oil. I started having to top off oil much more frequently over the last year, 1 quart per 1000 miles. The check engine oil light would turn on every month at random times while driving. Took my car to a shop; they removed 02 Sensor 1 and borescoped the exhaust system. Found oil leaks from valve seals, leaking into the exhaust manifold. A few weeks later, the check engine light came on for the first time (codes: P24D6 and U3501). Brought car to another shop; they scanned the car and the following codes were found: U350100 (Passive/Sporadic) - Control Module Input Power "A" Circuit Low U041600 (Passive/Sporatic) - Invalid data received from vehicle dynamics control module) P003000 (Passive/Sporatic) - O2 Sensor Heater Control Circuit Bank 1 Sensor 1 U105400 (Passive/Sporadic) - Information electronics 1 control unit No communication P24D600 (Passive/Sporadic) - Evaporative Emission (EVAP) system pressure sensor/switch B circuit range performance. The second shop also stated the valve stem seals needed to be replaced in addition to the Upstream Oxygen sensor and PCV valve. The car was brought to Volkswagen for repair under the extended warranty. Volkswagen confirmed the PCV valve and valve stem seals were bad and needed to be replaced. VW also noted smoke coming from the exhaust. The vehicle has 53k miles on it.

My Tiguan was towed on [XXX] to Beyer Volkswagen [4017 Valley Pike, Winchester, VA 22602] for service to repair a sudden and unexpected vehicle failure.  On [XXX], I started the Tiguan and noticed a hard start. I drove the vehicle about 4 miles down the road and noticed a smell of gasoline when I stopped and opened the door. I immediately drove the car home at which point I noticed gasoline on the road and driveway, as well as a heavy persistent smell of gas. I moved the vehicle to the road and had it towed [$95 at my expense] to Beyer VW for service. This failure rendered the vehicle undrivable and luckily was able to get it towed before it became engulfed in flames. [XXX], after getting the vehicle back for 1 week (dealership claiming repair fixed) the problem was not fixed and in fact gas spewed from the engine at a higher rate. Pictures attach showing about of gas which instantly dispelled at start and move from driveway to road. This is a critical vw problem that will result in fire.
