    Camshaft leak, stalling, followed by engine light

    There was oil in the electrical plug and it had started to make it's way down the wiring loom. The mechanic had cleaned everything up and replaced the wiring loom with a modified loom. He's since replaced the O2/Lambda sensor which improved things initially, but the revs still occasionally drop...

    Camshaft leak, stalling, followed by engine light

    After my previous disaster with fuses my 2001 W203 Coupe has been running great. Until I brought it in for a service that is. The mechanic replaced the camshaft magnet saying that it was leaking oil, and he replaced the wiring loom and cleaned it all up. Fair enough. I take it home and then the...

    Urgent help required - alarm going off after fuse removed

    Folks, First off, thanks for the responses. I tried most of what was suggested but to no avail. Eventually I caved in and phoned a local Mercedes dealer and had a word with a technician. He asked me to try the same things you guys suggested but again with no luck. I brought it in and he tried...

    Urgent help required - alarm going off after fuse removed

    Dammit - the drivers side! I was pulling apart the passenger side cause of the diagram in the book - I never considered that the diagram might be the wrong way round because of left hand drive/right hand drive differences! Cheers Maurice

    Urgent help required - alarm going off after fuse removed

    Okay, I've stopped panicking! I'm currently leaving the fuse until the morning. I've locked the car up using the emergency key, and to be safe, have removed all the valuables from it. I live in a very quiet cul-de-sac and it's 10pm - I'll get lynched if I start messing with alarms anymore at...

    Urgent help required - alarm going off after fuse removed

    Hi, I've been a bit of an idiot - we can save lectures until problem resolved hopefully - and have the result that I have an alarm going off on my W203 Sports Coupe. My rear demister isn't working and I had decided to check the fuses. Since the demister is at the rear I went to the rear fuse...

    W203 audio wiring guide

    At the risk of sounding like a complete idiot - which wire should I be tapping into for the cigarette lighter? I've got a choice of three, brown, blue and black (with some yellow). Any tips for how I would use a digital multimeter would also be appreciated. Cheers, Maurice

    W203 audio wiring guide

    The stereo I purchased (JVC KD-G351) comes with an ISO to proprietary loom. Fortunately the red (ignition) and yellow (battery) wires are swappable, so if I can get the same type of connector I can just plug straight in. Now to find the time to go to Halfords or Maplins. Doing my head in...

    W203 audio wiring guide

    So the standard head unit works by being permanently connected to the yellow (battery) connection, but is smart enough to not draw power permanently unless the CAN sends a message saying "ignition is on"? I'm not big with electricals (I'm a software engineer by profession) - what do I need to...

    W203 audio wiring guide

    Hi folks, First off, I'm a newbie here, and so apologise in advance for asking something which may be listed in an FAQ somewhere. I did a search on the forum (and on Google) but found nothing definitive. I got my C-Class Sport Coupe recently - it's a W203 I believe and was first registered in...
