2023 Volkswagen Tiguan: check engine light

Filed Sep 10, 2026 · Engine · OH

2023 Volkswagen Tiguan, approximately 34,316 miles. While driving on I-26 in South Carolina, the EPC warning and amber warning triangle illuminated. I pulled over and stopped. After approximately 10 minutes, I restarted because I was in an unsafe location. No warnings were displayed after restarting, but approximately five miles later they returned, and I exited the highway. After stopping, extensive engine oil was visible on the rear/underside of the vehicle. I immediately checked the dipstick and no oil was visible. At no time did I observe a low-oil-level or low-oil-pressure warning. An authorized Volkswagen dealer diagnosed a faulty oil separator causing internal engine pressure to build, which caused the oil pan to crack and upper timing cover to leak. The oil separator, oil pan and upper timing cover were replaced under warranty. During approximately two months before the failure, the vehicle had several times briefly displayed “Max engine speed: 3,000 rpm.” The night before the incident, the check-engine light illuminated but was no longer illuminated before the return trip began. The vehicle had received scheduled service, including an oil/filter change, at approximately 29,780 miles, only about 4,500 miles before this failure. My safety concern is the sudden pressure-related engine failure and major oil loss at highway speed, together with no observed oil warning despite no oil being visible on the dipstick immediately after the incident. The servicing dealer has stated that it does not know what causes these oil separators to fail. I am reporting this incident so the federal safety agency can evaluate whether it may represent a broader safety issue.

Currently in the 22-23 Tiguans they are experiencing an oil consumption issue. Where the engine is consuming oil at a fast rate. I am having to add oil to the car every 800-1000 miles. There’s several class action lawsuits against VW for this exact issue yet they refuse to fix the issue in our car even though it is still under warranty. In writing they told me it’s not consuming ENOUGH oil for VW to approve the repair and that it has to get worse before they will fix it. This problem CAN cause catastrophic failure to the engine. It can also cause the car to stall while driving putting myself and my family at risk. The service advisor admitted that the Tiguans are known oil burners, so much so that they now put in their manuals that burning 1qt of oil per 1000-1200 miles is within spec. It should not be burning oil at all! When I took it to VW bc the check engine light and low oil light was on they said they needed to perform an oil consumption test to see how much it was burning. Yet when I went to pick it up they said that I had to bring it back in exactly 630 miles to do the test. They wouldn’t say why they didn’t get it done that day which I thought was strange. I was unable to get back there at exactly 630 miles bc I work and they are in a different state. So I called to say hey I’m a little Over is that ok. They said no sorry ,we will have to do it at my next oil change. Which per VW is 10,000 miles or 1 year! They want me to wait up until one yr to test this? This is not acceptable! It is costing me money in extra oil every month , putting my family at risk, and putting the car at risk for catastrophic failure . Again, I have the proof in writing where they stated what I said above. As well as receipts and proof that I have taken it to VW for this issue yet they refuse to fix it.

I own a 2023 Volkswagen Tiguan (EA888 2.0L). The Check Engine Light has repeatedly illuminated, and multiple scans show recurring EVAP/emissions and network communication faults: P04F0 (EVAP purge line A performance) and P0451 (fuel tank pressure sensor range/performance), along with U1111 00 (“function limitation due to missing message”) and U1123 00 (“databus error value received”). While drivability may seem normal at times, these faults persist and clear/recur, raising concerns about fuel-vapor containment/emissions compliance and potential intermittent loss or limitation of vehicle electronic systems/driver-assistance functions due to CAN-bus communication errors. I’m reporting this because the condition is ongoing, produces a continual CEL, and may present safety and reliability risks if not addressed by the manufacturer.

I am experiencing a high oil consumption rate on my 2023 VW Tiguan. VW claims that the rate of consumption is within the 1 Quart every 1200 miles limit, but 3500 miles after an oil change, the check engine oil light came on and I had to add oil. 2000 miles later, it came on again and I had to add oil again. In a 10,000 mile oil change rated car, this would equate to adding 8-9 quarts of oil between changes. This is not normal oil consumption. The effects of increased emissions and premature fouling of the catalytic converter system alone is cause for concern, or the possible loss of engine power on the highway due to failure from lubrication loss, resulting in an accident. The car will emit blue/white smoke from tailpipe and rough idle randomly when the cylinders are overloaded with oil.

The contact owns a 2023 Volkswagen Tiguan. The contact stated that while driving 35-40 MPH, the engine warning light illuminated. The vehicle was leaking oil. The vehicle was taken to the local dealer, where it was diagnosed that the oil separator, PCV Positive Crankcase Ventilation valve, and gasket needed to be replaced. The vehicle was not repaired. The manufacturer was contacted. who confirmed there was no recall coverage. The approximate failure mileage was 56,000.
