    Hi Guys,

    New to the forums, hoping someone can help.

    I have a w203 Mercedes 2005 C180k SE Auto. I believe it's the W271 engine with almost 73,000 on the clock.

    Problem first started a few weeks ago, after coming off the motorway one day the temperature shot up (Car is usually "up to temperature" at 60c) by 20 to around 80 and the engine started to behave really erratically. Both happened when I was stopped at traffic lights, and pulling forward a foot or so would stop the shaking of the car. The revs during this would fluctuate probably around 200 - 300 up and down.

    Pulling away, this problem would stop and the temperature would cool.

    It then did the same juddering as i started the car after stopping at the shop on the way home of the same journey.

    The EML kept coming on and off, had a friend check the car and wasnt misfiring, atleast not in Neutral and he booked it into a local garage. They read the codes last week and the invoice confirms they have replaced the cam sensor magnet, seal and wire. They have listed on the invoice:

    "Laser"
    "MA2710510177 MAGNET"
    "MA009972348 SEAL"
    "MA271051002 COVER"
    "MA2711502733 WIRE"

    Not sure if that's the part number or not.

    Got the car back on Friday, took it to work on Saturday and the EML came on. After roughly 30 minutes of driving time, as i stopped it did that same erratic idling, put the car into Neutral and it stopped.

    It has only done it as described above. The temperature is good now, other than the first day or two (when we had that sunshine 2 weeks ago) but the EML is back and won't go away.

    Just put it back into the garage today, and they've been back intouch and told me:

    They've found Error Code P2054-002
    "continuous cam shaft adjustment incorrect position of exhaust camshaft"

    and also a "Resultant" code of
    P0020

    Stated original fault was "2008/008" which was fixed on above invoice.

    He's also told me it's likely to be the timing chain, but they don't have the equipment to work on the Mercs and i need to take it to Merc or an Indy.

    It's due a Service B in 4000 miles, hasn't had fuel filter, spark plugs etc changed since 2009 service, but is serviced everytime the light comes on at a Merc Dealer.

    Can anyone help? Maybe shed some light on if they've had the same experience?

    I'm buying a house currently, can't afford "Trial and Error" repair bills.

    Also, is the car safe to drive with the above?

    Thanks,
    Mike.

    You need to get a proper Star diagnostic scan. If you post the area in which you are based then perhaps we can suggest a local MB specialist.

    Hi,

    I'm in South Birmingham. Kings Norton, B38 area.

    I've just been and picked the car up, EML reset as it's been on diagnostic and car feels fine but i know it's only a matter of time before the light comes on again.

    He's told me should be safe to drive, hope he's right!

    Thanks, DSM.

    Gave them a call, got it booked in for Friday, hopefully it won't be an expensive fix!

    Yes your cam chain has stretched from the fault codes you give

    Hi WG,

    Is that a serious problem? Still safe to drive until it's in on Friday?

    I wouldn't. Very risky IMO.

    Newbie :w203 EML on

    Hi all
    Newbie here after some advice , just purchased a w203 c200 2001,
    Purchased it with the only fault showing was a light sensor fault on the dash. Me thinking it was just a matter of replacing a bulb went ahead with the purchase.
    Anyway whilst driving to work today I noticed the fault had cleared an " no malfunction" was now showing on the dash. Then the EML light came on , the car is driving fine as I finished my drive to work, I have it booked in at my local garage but would appreciate any ideas on possible causes.

    Thanks

    You will need to get the codes read....

    But what do you mean by 'light sensor' and 'bulb'?

    A C200 may have a M111 which is actually a good engine and does not have the chain problems a M271 has.

    Hi all,

    Just a update. Had the diagnostics checked today and it showed "5/6 running hot MAF sensor" also showed a high pressure fault but mechanic suggested that was due to the Maf failing.
    Could any one shed any light on this matter?

    Thanks
