2024 Volkswagen Tiguan: check engine light

Filed Sep 18, 2026 · Engine · TX

Symptoms started at 65k-70k miles, just after 50k warranty expired. First symptom was low oil warning and needing to add oil between changes. Then oil spots, then i found a bad leak and replaced oil pan, timing chain cover and assembly, turbo actuator. Warnings progressed to frequent low oil light, check engine light, blue smoke on start and acceleration, strong burning oil smell, and now visible oil spitting from tailpipe onto rear windshield. I now have to carry oil every time I drive. Timeline: bought new with 5 miles, no issues to 65k, 65k-70k start of leaks, 84k now 2 quarts per 50 miles and oil from exhaust. Ive notified VW about the situation.

On 8/29/2026, my 2024 Volkswagen Tiguan experienced a sudden mechanical failure while I was driving on the highway at approximately 55mph, with only 27,842 miles. Prior to this incident, I had reported to the VW dealership at my previous oil change that I repeatedly had to add oil between scheduled oil changes. While driving, the vehicle suddenly began producing a significant amount of smoke and the check-engine light came on. After I pulled over, fluid was visibly leaking from underneath the vehicle. A State Trooper responded and told me I was lucky the vehicle did not catch fire. The vehicle was disabled and had to be towed from the highway to the VW dealership. The VW technician subsequently diagnosed the oil separator as having failed. In a video inspection provided to me, the technician stated that the failed oil separator caused excessive pressure in the engine crankcase, which "blew out" the upper timing cover and oil pan. The dealership replaced the oil separator, upper timing cover, and oil pan. The dealership then performed an approximately 30-mile test drive. The technician stated that the oil level remained full, but the vehicle produced a "big blue plume of smoke." He then stated, "there's an issue with these vehicles and the cylinder heads," and advised that the cylinder head now needs to be replaced. The vehicle remains at the VW dealership. I am reporting this because the failure occurred suddenly at highway speed and resulted in substantial smoke and fluid loss, creating a potential fire and safety hazard. I am also concerned that significant blue smoke continued after the initial repairs and that the vehicle now requires major engine repair at fewer than 28,000 miles. Thankfully, there were no injuries or collision. uploaded: text with svc advisor, stating part of this is a known issue; screenshot from the video the dealer sent me - the web address to view the video is at the top. i do not have the police report yet

Catastrophic loss of throttle response and severe acceleration lag from a standstill under high ambient temperatures, presenting an immediate collision hazard. On more than ten (10) separate occasions, the acceleration on this vehicle from a complete standstill has unexpectedly dropped to a dangerous level, performing at or below the speed and power of an un-indicated "limp mode."This hazardous condition is explicitly triggered by ambient heat: it frequently occurs in temperatures above 90°F and consistently occurs when temperatures exceed 95°F. The defect manifests unannounced from a stop while sitting in traffic, idling at a light, or attempting to pull out or merge onto a roadway.Once the vehicle is in motion, the engine runs fine and all auxiliary systems—including the air conditioning, infotainment, and advanced driving assistance systems—operate normally. Crucially, the vehicle displays absolutely no dashboard warning lights, check engine lights, or stored diagnostic trouble codes (DTCs), making the malfunction impossible for standard onboard diagnostics to register. Over time, I have learned to detect a subtle, tell-tale change in the cadence of the engine idle that foreshadows when this dangerous throttle failure is about to occur.Based on the symptoms, the failure appears to reside within the electronic accelerator pedal assembly, throttle body, Engine Control Module (ECM/ECU), transmission control system, or a thermal management software conflict between these components. I have presented this vehicle to an authorized dealership, Lokey Volkswagen, on two (2) separate occasions for this exact issue. On both visits, the service department failed to provide any remedy, diagnostic resolution, or repair suggestions to the lack of stored fault codes.Because this severe lag occurs when trying to accelerate into live traffic, it leaves the vehicle dangerously exposed and creeping along at walking speeds. I firmly believe this defect will result in a severe injury

The rear view camera only works half of the time and gives and error the camera is not available at this time. There was a recall but the VIN on this car was not included The transmissions revs high before shifting at times and at time when not pressing the gas, coasting downhill No check engine or warning lights come on Both issues have been recurring over the last couple of months
