Security Module

Apparently, my security module is not working. I just noticed that there is one small 15 amp fuse on this module. If this is bad would it shut down the entire function of the module?

I do have a spare module from a 1999, I own an 01. Would I do any damage if I tried switching these out?

I am kind of desperate at this point I am not close to any service center. I had it in once and they just wanted to replace every thing without doing any significant trouble shooting. Thousands of dollars!

My biggest inconvience at this point is I can not lock the passenger door. My wife is getting kind of tired of guarding the car when we go places. Other than security issues I have a great car.

Any help would be greatly appreciated.

Are you talking about this unit under the seat? If so how do you know it is not working. Has a dealer with a PST2 hooked up to your car. Does the alarm work. When you say you cannot lock the car - do you mean with the remote. Need more info.

If it is the unit in the picture I would have to look up the part numbers to see if there is a difference. If they are the same and there is a problem with your original unit, then the next problem is that a replacement unit will not work unless coded by Porsche with the PST2.

Tool Pants,

Thank you very much for taking time out to look at my situation.

Yes the alarm does not work. A dealer has confirmed it with their PST2.

The car will not lock with the remote or the button on the dash.

The M535 replacement module I have has a part number of 996.618.260.07.

I will pull the seat ASAP and get the data off the module in my car.

did you get this resolved?  I have the same problem with my part # 996.618.269.07 so I was thinking of swapping everything
 Immobiliser Set: Engine Computer + Security Computer + Ignition + Key + Console Lock Cylinder + Door Lock Cylinder ( of ebay)

the only difference is the immobilizer part # is 996.618.605.00 the last 5 are different

 

will it make a difference because im taking the whole DME / security imm. / keys / ignition etc of the same 2.7 running car

 

any one?
