An outboard rear sensor has failed so all 4 sensors do not work.

I know how to remove the rear bumper to replace the sensors and have 2 to fit both outboard ones.

Can I just fit the new sensors and they will work or does the car need some reprogramming?

If anyone has done this already and can give me some advice I would appreciate it.

Many thanks I will try that.

The drivers side front drain tube does not drain but the left side does.
Resulitng in water overflowing onto the headliner running down the inside the A-Pillar upper and lower onto the carpet.
I have tried unblocking the tube with a small stainless coil and can get 110cm down the tube but no further.
On the left free draining tube I can still only get the coil down to 110cm also so I imagine there is some connection or bend at that point.

Does anyone know what happens beyond that point wher the blockage might be?
I am thinking that the tube may be bent or trapped somewhere.

I have in the past removed the wheel arch liners to check the the bulkhead drain plugs have been removed allowing them to drain freely.
I didn't notice another drain tube that might be the sunrroof tube exit.

Someone did suggest to me that the sunroof drain tube ends inside the bulkhead and isn't visible?
 

Many thanks for both replies and I will adopt both techniques.

I have managed it with the help og a G-Clamp and protective pad on the plastic.

I have managed to close the two on the left but the right hand ones are refusing to close.

I will open the left side and see if the right ones will then close.

The struggle goes on. 

How did Porsche expect a woman to get these on?

Thanks for the advice.

Is it just as tough to release the bars or do they just spring open when unloked?

have a pair of original T-Track system roof bars that drop into the roof channels
You are suposed to slide and align with one of the 6 notched out positions.
Then close and lock the plastic end cap covers.

I have attempted this several times but the force required to close the end caps is so great that I am afraid that the plastic will break.
Has anyone experience/advice on fitting this system?
