VW Suran Throttle Issues Causing High Fuel Consumption

Having experienced similar symptoms with my VW Golf 2013, I can confirm this could be related to the throttle body and control valve system. During idle, my engine showed irregular RPMs and increased fuel consumption, which turned out to be a defective throttle position sensor. The throttle body components often accumulate carbon deposits, affecting proper air-fuel mixture control. However, in my case, simple cleaning was not enough. The entire throttle body assembly needed replacement since the electronic throttle control was malfunctioning. Important signs that indicated a serious issue: Rough engine idle, Delayed throttle response, Increased fuel consumption, Starting difficulties, Check engine light activation A proper diagnosis revealed that carbon buildup was just a secondary issue. The main problem was electronic, affecting the throttle position sensor and accelerator pedal module communication. Given your symptoms match closely, recommend getting a professional diagnostic scan rather than attempting DIY cleaning. Electronic throttle issues require specialized equipment for proper calibration after any repair work. This is considered a serious repair as it affects both engine performance and safety systems. The car should not be driven extensively if experiencing significant throttle response issues.

Thanks for sharing your experience with the throttle body problem. My Spacefox had similar symptoms last year, poor throttle response and excessive fuel usage. The mechanic diagnosed an issue with the air intake system and control valve. After reading your detailed response, I realize I should have paid more attention when these symptoms first appeared. Quick question: how much did the throttle body replacement end up costing you? Also, have you experienced any other issues since the repair was completed? Just want to make sure I budget correctly if I need similar work done.

After getting my throttle valve fixed at the shop, the car runs perfectly now. My fuel efficiency has returned to normal and startup issues are completely gone. The total repair came to 205€ for replacing the defective accelerator pedal module, which was causing the poor communication with the car throttle system. Since the repair three months ago, the air intake and control valve have been working flawlessly. No more rough idling or hesitation when pressing the gas pedal. The mechanic showed me the old throttle body components, and there was significant carbon buildup affecting the electronic sensors. The investment was worth it considering the improved engine performance and fuel consumption. The car feels responsive again, just like when it was new. No additional issues have surfaced since the repair, confirming that the throttle valve was indeed the root cause of the problems. If your symptoms match what I experienced, getting it properly diagnosed and fixed sooner rather than later will prevent potential damage to other engine components and save money on wasted fuel.

After reading all these helpful responses, I finally got my car checked. The mechanic confirmed it was indeed a throttle position sensor issue, along with some carbon buildup in the throttle body. The total repair cost came to 180€, which included cleaning the air intake system and replacing the faulty sensor. The difference in performance is remarkable. My fuel consumption has dropped back to normal levels, and the engine starts smoothly every time. The throttle response is much more precise now, no more hesitation when accelerating. I wish I had addressed these warning signs earlier instead of waiting. The mechanic showed me the dirty throttle body components, and honestly, I was surprised how much buildup had accumulated. They also performed a complete electronic diagnosis to ensure the new sensor was properly calibrated with the engine control unit. For anyone facing similar issues, getting a proper diagnosis early on is definitely worth it. The repair has paid for itself in fuel savings alone.
