Still having central locking problems

Hi Guys

I have replaced the PSE pump on my SLK230 after my local dealer diagnosed it as faulty at the last service, it has NOT fixed the problems with the car.

Here is what is wrong:

The central locking does not work either from the key or the radio fob. The indicators flash (once for opening and three times when the locking button is pushed) but the alarm and immobiliser do not set. The interior and boot (trunk?) lights do not work when the doors are opened either but the interior light comes on when the switch is set to the on position.

I can hear a "click" from the PSE pump when I operate the radio key fob but nothing happens. I have also checked the fuses and all are OK.

Any ideas anyone?

Would really appreciate some help!

Thanks in advance

Martin, did the dealer check for fault codes and actual values on door switches, lock/unlock signals, etc.?

did they do the coding also on new PSE pump?

all fuses okay?

I'm not sure what the dealer checked for, the report he gave me only stated that the PSE pump was faulty. The replacement PSE pump was a secondhand unit from a SLK230, the same year as mine so should not have needed coding (right??). I eventually tracked down a 04 part number unit although this does have two additional connectors fitted, I have assumed they are not neccessary for my model....

The fuses all checked out OK.

Thanks
Martin

this only shows that the PSE pump motor doesn't work.

try the coding.
