2015 Volkswagen Passat engine problems

Filed Feb 5, 2026 · Engine, Fuel system · DC

The contact owns a 2015 Volkswagen Passat. The contact stated that while driving at various speeds, the vehicle sputtered intermittently. The vehicle was taken to the dealer, who diagnosed the vehicle and determined that fuel was leaking into the engine compartment, causing engine failure. The contact stated that the dealer had repaired the vehicle and possibly cleaned the engine. The dealer had informed the contact that the engine would last 4-6 months before complete engine failure. The vehicle was returned to the contact; however, while driving approximately 35 MPH, the vehicle sputtered and then lost power. The vehicle was restarted after several attempts to continue driving. The vehicle was returned to the dealer but was not repaired. The dealer suggested that a new vehicle be purchased. The contact searched online and became aware of the federal safety agency Campaign Number: 15V028000 (Fuel System, Gasoline); however, the VIN was not included. The manufacturer was made aware of the failure and confirmed that the VIN was not included in the recall. The failure mileage was unknown.

My vehicle is a MY2015 Passat TDI SEL with the EA288 (CVCA) diesel engine. Water Pump Failure Occurred at 99488 miles. Leaking coolant from underneath the engine and the expansion tank bottle became empty. Vehicle was parked after a quick 8 min drive to work from home in the morning (~8:45AM) and when I came back at 12PM around 1 quart of coolant had leaked out. Luckily I was not on the freeway or driving the vehicle where it would ride on its torque curve increasing probability of catastrophic failures even after there are usually software induced engine protection derates in place. Official service interval for water pump and timing belt on this engine is 130000 miles but there have been numerous field incidents of pre-mature water pump failures which can be very expensive to fix (~2500 USD). Volkswagen/Audi already have a class action lawsuit against them on their 2.0 TFSI (EA888) water pump failures and I'm wondering why their MY2015 2.0 TDI (EA288) diesel engine has not been investigated for the same. This engine was only available in certain MY2015 VW/Audi vehicles but just because the cumulative number of vehicles with this engine are lower does not mean that it shouldn't be investigated for a very similar manufacturing/design defect of the water pump. I would strongly urge the federal safety agency to do a similar investigation on this 2.0 TDI engine and hold the manufacturer accountable.

Subject: Request for VIN Review and Recall Inclusion – Camshaft/Vacuum Pump Failure (Recall 23R1) Dear Volkswagen Customer Care / the federal safety agency Representative, I am writing to formally request a manual review of my vehicle’s VIN in relation to Recall 23R1, which addresses camshaft lobe interference with the brake vacuum pump in certain 2015 Volkswagen Passat models. My vehicle, a 2015 Passat, recently experienced a failure of the brake vacuum pump, which required replacement. Upon inspection, it was determined that the camshaft was interfering with the pump, consistent with the failure mode described in Recall 23R1. Despite this, my VIN does not currently show an open recall. Given the alignment of symptoms, including camshaft-related damage and vacuum pump failure, I believe my vehicle should be included in the scope of this recall. I am requesting: - A manual review of my VIN and production batch - Consideration for inclusion in Recall 23R1 - Reimbursement or goodwill support for the repair costs already incurred I have documentation of the repair and am happy to provide technician notes that confirm the nature of the failure. I appreciate your attention to this matter and look forward to your response.

2015 Passat TDI sudden complete power loss while driving, including highway incidents. Vehicle stalls with no warning, creating immediate safety hazard. Symptoms match documented crankshaft position sensor failures in identical vehicles that VW has repaired under warranty for other owners. VW Customer Care closed case requiring 'duplication' of safety defect before repair. Request immediate safety investigation. I am reporting today's incident however this issue has been occuring since May 1st and occurred on numerous occasions with today being the most unsafe.

Gas and Oil comsumption is way too high … Almost every 600-1000 the low oil lights turns on! Check engine on almost all the time due to an error with the oxígen sensor. EPC light gets on very frequently and the car loses speed. Also vehicle has a constant rattlesnake sound when speed is low. Issue was reported some years ago to a local VW dealership in Georgia but they never took care of the issue. Ongoing for a couple of years!. No additional details

After having the government approved and MANDATED Phase 1 and 2 Dieselgate fixes performed on my VW Passat TDI it has randomly lost power and or stalled while at highway speeds at least 6 times. The last time my 16 year old son was left stranded in the middle of a busy four lane highway narrowly avoiding being hit and seriously injured and/or killed. Apparently there are thousands of these cases (a class action lawsuit filed in 2018) on the road. Why haven't I been notified? This mandatory fix is much more dangerous then the original issue it seeks to address. From what I understand, the fix is causing the DPF regeneration sequence to occur much more often and much hotter, thereby cooking/melting/boiling the entire cooling system and shutting the engine down without warning. My vehicle has been in the service dept of VW for over 6 months (this last time) because they cannot figure how to fix it permanently. VW Corporate is very aware of the situation and has fed me a bunch of [XXXX] not even a child would believe and has refused my suggestion to self report the problems to NTHSA and CARB. If the cars are not taken off the road this issue will definitely (if not already) result in major injuries and likely death. I have done my duty notifying this government agency and now if a tragedy occurs there will have been actual notice as required by the law.

While driving the EPC light came on and the car stopped driving. Vehicle was towed to local VW dealership, a FULL engine rebuild took place and a faulty intake valve spring was found, after replacing the injectors and seal kits. Then to replace the faulty electronic ignition switch. Over $3k in repairs for faulty parts. It was a safety risk because the vehicle stopped working in the middle of driving, in traffic with no other indication that something was wrong prior on a major road in the city. Since then, the vehicle has had constant issues with oil being low even after an oil change, no leaks were detected or reported. Also, the airbags and clockspring was supposed to be replaced. My airbag light came on in 3/2023 and it sounds like the clock spring is broken. Horn and electronics do not work from the steering column.

I have no heat on the passenger side of the vehicle from any of the vents. The windshield would ice up due to this. The drivers side works fine. This car does not have Climatronic. It has manual controls. I have been told the heater core is clogging by my mechanic. This is a 2015. VW extended the warranty for 2012-14 Passat TDI's with the CKRA engine however this is a 2015 with the CVCA TDI engine. Is there any extended coverage for this generation engine? I don't want this to develop into a larger issue with deficient EGR cooling problems. The heater core in the 2015 is the same part number used in previous model years which are covered by the recall.
