Hello all,

 

I read quite some people have failing electric boot openers on the Estate.

Do these electric boot struts all fail, eventually? I read a lot of people simply change them to gas struts.

 

How can the electric ones be treated? Grease them when opened?

Keep them clean? Lube them?

The part number should be 3T9 827 851B.

Do all struts having this number fit or are there struts with 2 connectors and 1 connectors?

This is well known issue and main reason, why electric struts motor will fail is water and humidity passing the sealing. Often electric motor brushes sping will be rusty and broke, also electric circuit board will fail. I´m in progress of compiling video tutorial of repairing electric struts, but it´s very difficult to find brushes sping spare parts. I looked cordless drills motors spings, but I haven't found the right one.

 

I´ll add here my video of rusty brushes springs:

My springs were rusty but not broken. Brushed them of and lubricated Them so now they move freely. The electric rotor is also rusted and doesnt move freely. Is it possible to remove the rotor? 

Would spraying WD40 as preventive maintenance and using white grease (the grease they sell in the bike shops) would help as preventive maintenance ?
