2015 Volkswagen Golf Sportwagen engine problems

“The contact owns a 2015 Volkswagen Golf Sportwagen. The contact stated that while starting the vehicle, there was an abnormal sound coming from the engine. The vehicle was taken to an independent mechanic, who determined that the camshaft module and variable valve timing (VVT) gears needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 97,900.”

“Engine fire due to exhaust equipment malfunction, if it was not attended to or noticed quickly it could lead to loss of control of vehicle, causing injury or death to occupants or other motorists. This occurred after having a recall completed.”

“In the last year, my car has experienced multiple instances of the Diesel Particulate Filter (DPF) warning light, check engine light, and a flashing glow plug light on the dashboard. Despite multiple visits and repairs at Sheehy Volkswagen of Springfield, these issues persist, particularly in sub-freezing temperatures. Upon independent inspection of the engine compartment, I found multiple exposed wires, broken wires, and poorly repaired broken wires. The most significant concerns are as follows: Repeated DPF Issues: Over the last three years, the DPF warning and related issues have recurred each winter. Initial attempts to rectify the issue included a DPF regeneration procedure, which temporarily cleared the fault codes but did not address the underlying problem. The DPF was finally replaced in mid-2024, yet the same problems manifested with a brand new component just months later. Extended Repair Time: Sheehy Volkswagen of Springfield had my vehicle for a total of six months (Dec-23 to May-24), during which they were unable to diagnose or fix the problem despite escalating the case to Volkswagen HQ (Business Case Numbers: BT1167682 and BT1177805). This delay…”

“The emissions modification calibration by Volkswagen causes the coolant to be exposed to elevated temperatures due to higher exhaust gas recirculation (EGR) use to control emissions. These elevated higher temperatures degrade the coolant faster than designed and lead to precipitates falling out of solution in the factory filled G13 coolant. This causes buildup and deposits to form throughout the cooling system, particularly in the heater core which can block proper coolant flow & lead to coolant system failure, specifically of hoses associated with the heater core. When these fail the engine can over heat, and stop which causes loss of steering, propulsion and braking abilities. There is a similar problem on 2012 models with the TDI engine, which has been addressed but the 2015 models are being stranded on the roads creating a safety hazard to the drivers of the vehicles and other motorists on the road.”

“Thermostat housing and water pump are leaking coolant. It is available for inspection. It can cause my engine to overheat and/or fail while being used. It has been confirmed by a dealership. It has not been inspected by the police, manufacturer, or insurance company. There have been occasional reports of low coolant, and the coolant drains significantly faster than expected especially in cold weather (e.g. needing to fill coolant every 7 days). It was first repaired in 2019, and has since failed again.”

“While normally driving on the street, I noticed that the car started to overheat and could hear the radiator working to keep the heat level normal. I stopped and did not notice any leaks and added coolant to the car after I left it cool for about 3 hours. The problem went away but i still took it to the dealership and i was told it might be the head gasket of the engine or thermostat/waterpump, a $4000 repair. Was advised to just sell the car. VW should address this issue as it has been a long issue now”
