According to two local dealerships in Atlanta the PSD Reservoir is now NLA.

Mine is plugged solid.

I thought Roger had them - that's my next call.

anytime a part goes NLA, its a bad day for all.


why do the reservoirs get plugged? from non use?

 

Bought a new one a couple of years ago because I read on the list they might be NLA
Just installed it along with a flush

 

There is a filter of sorts at bottom of the resi.
I have seen threads over the years on cleaning and re using, but honestly I just replaced when I needed to.

Its hard for for me to believe it would stay NLA. Wasn't it a shared part with all P-cars at the time?

 

Removed the filter - it is plugged solid.

Picture:



The filter has a part number - 964.355.183.00. Not found on my list of Porsche inventory websites.


My plan B is an in line fuel filter.

 

Ahhhh
Sorry Kevin, thought we we talking power steering resi.
Carry on

 

Placed an inline filter and tried to flush the unit. No love. Dropped the unit and found the bleeder orifice totally plugged with some blue material. Looks like the innards of the blue supply hose, but not sure that how it could get there.

Anyway, did some bench testing and it appears the pump while it sounds like it is working is not. Not really surprised. No fluid could get to the motor and it's likely the pressure switch would not tell the pump to stop. If the brake fluid lubricates the pump like the fuel pump that could lead to pump failure.

I have a spare PSD unit and confirmed the pump pushes fluid from the reservoir to the bleeder valve. I'll swap and see if that clears my differential control error.
