Is it dangerous to drive with a faulty fuel cap?

Not critical for safety, but it wastes fuel through vapour loss and will keep triggering the check engine light — replace when convenient.

How do I know if the cap itself is the problem?

If tightening the cap fully doesn’t clear the fault code after a few drive cycles, the cap’s seal is likely worn and needs replacing.

What is the cap made of?

Plastic with a rubber sealing ring, sometimes with a pressure-relief mechanism.

The EVAP system monitors for a sealed fuel system — a cap that isn’t fully tightened or has a worn seal lets air in, which the system detects as a leak.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
