Is it dangerous to drive with a faulty ECU?

Yes, this is the central computer controlling core engine functions — significant faults here can cause the engine to run poorly, stall unexpectedly, or not start at all, so this should be diagnosed by a specialist promptly.

Can a used ECU be fitted from another vehicle?

This requires careful matching to the exact engine variant and specialist programming/synchronisation — an incorrectly matched or unprogrammed unit generally won’t work correctly.

What is the ECU made of?

A sealed electronic circuit board with a microprocessor, memory, and extensive input/output circuitry, in a weatherproof housing.

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.
