Let's not underestimate the cleaning of the lambda probe.

Model: Volkswagen Volkswagen Various
Part: Oxygen sensor

Video tutorial

In this video we can see how, despite all the maintenance being done regularly on the car - which in this case is a Volkswagen, but it's not crucial, it could be any car - the engine light continues to be on. The YouTuber suggests that the problem could be the lambda sensor (also known as the oxygen sensor), which can be easily cleaned by oneself.

However, we do not recommend at all to clean it with WC descaler; it seems like a rather aggressive method.

Instead, we suggest a specific product, which will clean the component much better: a canister will cost you only 11.09 euros on Amazon with the code B00295EEBK, free delivery for Prime customers.
