PSE help
 

Update on 1999 SLK230 thread

I bought the pse module and plugged it in today.......but it didnt work :(, now my wife is mad I spent 800 on it. The alarm still goes off when i plug in the battery...what else could this be? is there a special way of plugging it on..or would teh wrong batter also cause this problem? since i also bought a new battery

oh another thing...the module has a diff part number on it

what part number is old? new? where did you buy the pump? what was the main issue that caused the pump to be suspect?

well I called the dealership and they said this part number is an upchange from the old part number so it shoudl work.
all the symptoms are the same when i try to start the car except now the lights dont flash with the alarm anymore.
i really dont know what to do....what else could it be besides the module?

the one that ends with 448 is the old one
