Signs of a faulty part

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

Pedestrian-protection system warning light on the dashboard
Fault codes on diagnosis
One side of the bonnet fails to lift when the system triggers

Installation information

Requires disconnecting the battery and waiting before working on it — fitting is normally done at a specialist workshop, followed by a full system check.

Frequently asked questions

On some systems the drive is built directly into the hinges (rather than a single central actuator), lifting both sides of the bonnet at once for an even effect.

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.
