What is the reason for the EPC light on and body shaking in the Tiguan?
2 Answers
Tiguan EPC light on and body shaking reasons: Severe engine carbon deposits. The power of the engine comes from the engine piston moving downward, sucking the mixture of gasoline and air into the cylinder, and then the upward-moving piston compresses these oil and gas into highly combustible gas. The spark plug ignites it, and the piston is pushed by this powerful explosive force, causing the engine to generate power and resulting in shaking. The Tiguan has a length, width, and height of 4506mm, 1809mm, and 1685mm respectively, with a wheelbase of 2684mm. The Tiguan comes standard with ESP body stability system, EBD electronic brake force distribution, and ASR traction control. Front dual airbags and front side airbags ensure the safety of passengers, and the standard child safety lock also emphasizes the safety of children.
A couple of days ago, my Tiguan had the same issue - the EPC warning light came on accompanied by noticeable engine shaking. I immediately checked the throttle body and found terrifying amounts of carbon deposits inside, which can obstruct proper throttle valve operation. Then I suspected it might be the spark plugs, as the technician mentioned they were nearing end-of-life during the last maintenance. When encountering this situation, it's best to first park the car safely and try restarting the engine several times. If that doesn't work, call for a tow truck immediately since stalling on the road is dangerous. I regularly use fuel system cleaner additives every month and clean the throttle body periodically - these preventive measures are crucial. I recommend visiting a professional repair shop ASAP to connect an OBD scanner and read the trouble codes for accurate diagnosis.
