Since I got my SL55AMG the Alarm siren did not appear to be working.. indicators would flash, but no siren.
The fault code seemed to confirm the siren was faulty.. today I fitted a new replacement from MB .. quick and easy to do, only took 40mins.
The siren as most will know suffer from water damage or battery leaking and damaging the circuit board and causing other electrical issues.
now working as it should.
MB have updated the part a few times.. and hopefully improved it.
The original part number is A 203 820 38 26
then A 171 820 25 26
The latest part number is A 219 820 32 26
I now have 3 chirps on locking and one on unlocking.
Top siren is the new one (£100)
old one
