Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Engine won’t start or runs very poorly
  • Multiple, seemingly unrelated engine-related faults appearing together
  • Check Engine light constantly on with numerous fault codes

Installation information

Mounted in the engine bay, connecting to the extensive engine wiring harness — requires specialist programming/coding to match the specific vehicle and, often, the immobiliser system.

Frequently asked questions

The ECU needs to be correctly programmed with software matching the exact vehicle, engine variant, and often synchronised with the immobiliser system — this typically requires specialist diagnostic equipment and expertise.

  • 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.
