Why do the doors lock unevenly?

Often a vacuum leak in one of the system’s hoses, rather than a fault in the pump itself.

Is a faulty pump a safety issue?

Not for driving safety, but it reduces convenience and the anti-theft security of individual doors.

A compact electric pump that generates suction for the pneumatic system.

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.
