Does the system need reprogramming after replacing the panel?

On some models the new panel needs software adaptation through diagnostic equipment.

Is a fault here a safety issue?

No, it’s not critical to safety, just cabin comfort.

Can sticking buttons be repaired instead of replacing the panel?

Sometimes cleaning the contacts helps, but for significant wear, replacing the panel is more reliable.

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.
