Etios Poor Starting Fuel Consumption

My 2020 Toyota Etios diesel is having serious issues. At 132,603 km, fuel consumption has gone through the roof, and it's starting poorly in the mornings. Online, some suggest a defective throttle valve, possibly from a dodgy accelerator pedal module? Has anyone experienced this?

Sounds familiar! I had a similar problem with my old Renault Megane. Symptoms were almost identical – terrible fuel economy and struggling to start. I'd suggest checking for dirt or grime around the throttle body, maybe even try a throttle cleaning spray. But honestly, it could be a sensor issue messing with the engine idle.

Thanks! Is 'throttle cleaning spray' something I can do myself, or am I risking making things worse? Also, if it is the accelerator pedal module, is that something a novice can tackle, or is it best left to the professionals? Roughly how much did the repairs cost you?

Cleaning the throttle body can be a DIY job, but if you're not confident, I wouldn't risk it. As for the pedal module, I really wouldn't advise messing with that yourself. I ended up taking my Megane to a workshop, they replaced a faulty sensor and cleaned the throttle. Cost me around 180£ back then. Best bet is to get it properly diagnosed!

Okay, thanks! Sounds like a trip to the mechanic is in order. I appreciate the insight – at least now I have a better idea of what to expect. I got the car back, it was indeed the accelerator pedal module, cost me 205€. All good now!
