Motorraum: Zweite Luft Pumpe und E46 glas kratzer (English)

[Sanyi]

Hello Guys,

I have a problem with my car. 1 year ago the secondary air pump was filled up with water... we thought that the pump was dead, that's why it was full with water. But 1 year later, today, I was at the service, and the new one was filled up also, and it was dead.... the pipe from/to this was also filled up with water... I don't know what is the problem... Any experience, or suggestion?

And...

I have some scratches on the side window on the driver side. It cramp me a little bit. What do you think, how can be repair these? I thought about the polishing, but I heard it is bad on the glasses on the car. Or anybody know that technology, which is good for these without changing the glass? ( I don't want glass distorsion, ohne " licht dellen") Has the polishing that kind of technology, which would be good for me? Or any suggestion?
Anybody recommend a good service in Austria or Germany, which can do this?





Best Regards,

Sanyi

If you can understand German, you should read the information on the following page:

Go to  www.ms-motor-service.com
->Onlineshop in the upper right
->Gastzugang
->select your car
-> read the information on
Sekundärluftpumpe
Sekundärluftventil

As far as I understand, they say that if you replace the secondary air pump, you should also replace or at least check the connected valves, because these valves ensure that the pump doesn't fill up with water.

The valves should be number 8 in this figure:
