![]() ![]() ![]() It is generally around 60 whereas, it was 90 now. Over the period of next 6 days, he got the engine cleaned thoroughly, coolant box cleaned, pipes replaced, coolant and engine oil replaced.Īfter I received the car, I observed that engine temperature was unusually high. So I sent the car to garage on a flatbed and he confirmed the google knowledge. Quick google suggested that the engine cylinder head gasket must have been damaged allowing coolant to mix with engine oil. So I pulled over and checked the coolant level after letting the car cool down for about 20 minutes. Last week, the coolant sensor lit up mid-drive. It was working fine till last week with almost no issues. Our experienced technicians have the skills to repair all of the most common issues these engines have.I have been Audi Q7 (2011 model) 3.0 V6. If you live near Kelowna and own an Audi with the 3.0 TFSI engine that needs service, schedule an appointment with Motor Werke today. If you feel like your 3.0L TFSI Supercharged Audi needs some love, the team here at Motor Werke is here to help! ![]() When this happens, you will notice less smooth engine operation. The pulley uses rubber to deaden vibrations, and over time this rubber will blow out. The front damper pulley reduces vibration and contributes to a smoother driving experience. ![]() If you are getting your intercoolers or crank vent valve replaced, it’s a good idea to have the intake valves checked for carbon buildup. In order to perform a carbon cleaning, the supercharger must come off. An engine choked by carbon will idle rough and feel down on power. The poor fuel quality in Canada contributes to more rapid carbon buildup. If the diaphragm within the valve rips, the excess blow-by can trigger a lean code. This condition can cause a power reduction and may result in an engine seal blowing out due to excess pressure. If it becomes stuck closed, the engine will build excessive pressure within the crankcase. The crankcase vent valve can fail in two ways. The valve sits under the supercharger, meaning the blower will need to be removed to perform the service. The crankcase vent valve is responsible for preventing excessive crankcase pressure. Sometimes, removing the timing covers can distort them slightly, especially on older motors. When correcting a leaking upper timing cover, it’s best to replace both the gaskets and the covers themselves. The covers protecting the top of the timing system have a tendency to leak oil. The timing system on the 3.0 TFSI is located at the rear of the engine. The superchargers come off quickly, and the intercoolers themselves are not particularly expensive for an Audi part. Luckily, correcting this problem is relatively easy. Once the leak reaches a certain point of severity, you may get a check engine light and notice your car running rough, indicating a misfire. These leaks are typically slow, but as they get worse you will start to notice your coolant level dropping with no visible leaks. The air-to-water intercoolers that sit below the supercharger can also begin to leak. Hoses start to leak as the engine ages, and you may notice droplets of coolant in the engine bay depending on the severity of the leaks. Some of the most common coolant leaks on the 3.0 TFSI happen at the water pump, thermostat, and around the coolant hoses under the intake. That being said, there are five main issues this engine can run into, and we will be covering them here. As far as Audi engines go, this one has been incredibly robust, with few major issues plaguing owners. With forced induction from a Roots-type supercharger, this engine is capable of some impressive power figures rivaling and outperforming V8s used in older Audi models. Audi’s Supercharged 3-liter V6 engine was introduced in 2008 and has been a workhorse motor used in everything from the high-performance S4 and SQ5 to family haulers and large sedans like the Q7 and A6. ![]()
