central locking problem

4 posts in this topic

hi there, i'm a newby to this forum. i need help for my 97 boxster 2.5 tiptronic.

my boxster's engine failed on a rainning day, it was towed to a local car electrician and had the fuel pump and the control module (M531) replaced, and re-programmed. after i got the car back, i have expeirenced a few problems since:

central locking doesnt work with my remote (aftermarket), nor my keys, nor the central locking button. I have to lock my car with emergency locking method ( turn the key 3 times) or key lock each door individually. I'm able to use the remote control to unlock though. when i press the remote button, side lights do come up though no horn sound.

other problems are:

driver side window doesnt drop a little when i open the door; sometimes it does drop a bit once the hendle is pulled (both from inside and outside) but as soon as i release the handle, it goes up straight away;

the interior light doesnt ligh up when doors are opened, only lights up when i manually set it to 'always on' position;

I would like to know if above are related to the reprogramming of the control module, or could it be something else. I was told by the auto electrician that the driver side door lock unit may need to be replcaed. would this be the solution or? (btw, i was charged AU$2,500 by him for the job he did)

Maybe i'm wrong, but i have the feeling that all these problems are something to do with the programming. everything were working fine before.

any advice will be very much appreciated.

I know some things acted real funny on my car when I swapped the battery out. Later I went to turn on the radio, entered the radio code and things seemed to return to normal. I have no idea as to if it was a coincidence or by design.

Is it possible that while your car was laid up for repairs some heavy rain or other water source caused some water accumulation beneath the driver's seat. The central alarm and locking functions are governed by the electronic module which is mounted beneath the driver's seat. When it gets wet, it can cause some of the symptoms you describe. A few posters on PPBB have successfully taken the module apart and dried it with a hair dryer, and reassembled it to find everything working again. A few others have tried the same method but were not so fortunate because the water was in there too long, etc...

Perhaps take out the module and take it apart to inspect for moisture. That may give you a place to start or to eliminate as a possible cause.

thanks for the help. those problems i'm experiencing now are actually after the module been replaced with a new one. i just wonder if they are caused by incomplete programming of the new module.
