Hi everybody,
I'm new to this forum as a member but have been reading posts and lurking for so long, I thought I'd join in, sadly with an issue I could use some help with - so not all that altruistic I'm afraid. Any help would be appreciated, I'll try and be as clear as I can in my wording below, but sometimes I don't know the correct Mercedes terms for some of these things. I'm fairly capable with a set of tools, but often time limited.
I have a W212 E350 Bluetec on a '65 (2015) plate, which recently saw the alarm going off silently (hazards flashing fairly fast) as soon as I pressed the lock button. I could then cancel the hazards by pressing the lock button a second time.
I have an AUTEL AP200 system for home DIYers, and it suggested LIN BUS 2 Faulty, as well as communication with the alarm siren. Understanding that this is likely the alarm siren causing both issues, I took the car to a Mercedes specialist who ran their STAR system over it and came to the same conclusion. They fitted a new alarm siren (£147 for the siren alone) and the silent alarm no longer happens when I lock the car. From the outside perspective, it seems to be normal and fixed.
However, I now get three tiny little beeps when I lock the car, and one when I unlock the car, that seem to sound as if they're coming from the front nearside area (opposite side to the siren I believe). It's driving me nuts, and I can't disable it. The 'acoustic warning' is switched off - the one that fires the horn when you lock it - so it's not that setting and definitely not the horn making the noise. I know it's tiny, but I'm a real nut-job for the details and it makes my inner Victor Meldrew grumble every time I lock/unlock the car.
In addition, if I press the button in the roof control panel (roof lining just behind the windscreen) to disable the interior motion sensor before I get out, it flashes red quite fast (compared with the slower flash I get from the button to disable tow away protection). However, not getting any fault codes on a complete system scan. Worth noting, when the alarm siren was faulty, pressing either button did not work at all (no LED on, off or flashing).
Has anybody got any experience with this or know what I need exactly to code the unit out to silence the dreaded beast? I'm reluctant to go back to the specialist as they scuffed my front bumper at some point over the two days they had it, and although only small, is enough to put me off going back. I won't mention their name as they were decent enough to say they'd fix it and didn't try to argue with me that it was their error, but as it's so small, the fear of them making more mess when fixing it with overspray or slightly unmatched paint is greater than the likelihood that it'll polish out to something only I'll ever notice. That and they're over an hour away, so requires a lot of messing about!!
