    How to re-enable SBC in W211?

    Hmmm... I saw 5B10 check control unit N15/5 (Electronic selector lever module control unit) error. We'll see after battery replacement it that's related. Any idea if that's coded somehow or it's a straight swap from a donor car?

    How to re-enable SBC in W211?

    Do you get message "Convenience functions unavailable. Battery protection yaddayadda" once in a while after the car has not been used for a few days? I do..

    How to re-enable SBC in W211?

    I got the area set to "rest of world", so it's not it. Looks like re-enabling SBD Hold might be a trip to the Developer mode - I'm not going to do it myself. unless I find step-by-step guide.7 Edit: The aux battery is dying (the car was parked for a while), so it might be all OK with the...

    How to re-enable SBC in W211?

    W211, SBC was working fine. The car is after SBC reset by an indy a few years ago. I borrowed DAS/Xentry to fix some problems with my another merc, but I decided to hook up the W211 as well. There were some errors (stupid me, I've no screenshots), but it was nothing serious - otherwise I'd...

    M271 - source of oil in intake manifold?

    Thanks! I'm planning to get to the PCV valve (that's the one under the compressor?). I don't think MAF is oiled. It's MAP.

    2005 C180K MOT Emissions failure - advice sought - help!

    For future reference: in my case problem was with loose contacts on the ECU. Probably damaged by one of the garages trying to find the earlier problem with P0170... I found it by accident - I pushed the cable next to the 96-pin ECU plug and the engine changed revs, so I started detailed check of...

    None as far as I know. I ended up buying & borrowing some equipment to do DIY diagnostics after 3 garages failed to fix emission problem (I fixed it!). I hope someone will prove me wrong and post some contact details of good merc specialist.

    I registered long time ago, but I wasn't active. 2 mercs with M271 engine on the driveway. Talk to me with the tech jargon only ;-) Current hobby: nailing down P0133 in SLK200 and measuring whatever can be measured around M271 with oscilloscope.

    M271 - source of oil in intake manifold?

    I found out that there is some oil in the intake manifold. Are there any possible sources of oil leak into the intake manifold beside the breather hoses? Photo shows MAP sensor...

    SLK200, P2046-032, Sensor signal in case of inertia fuel shutoff IMPLAUSIBLE

    OK, I think I got my answer: Fault: P2046-(32) Sensor signal for overrun fuel shutoff IMPLAUSIBLE (P0133) Setting conditions: A fault is present when the O2 sensor signal during deceleration does not lie between 2.5 volts and 4.9 volts. Notes: P2046-(32): If the sensor signal is too low when...

    I have problem with returning error: P2046-032 G3/2(O2 sensor upstream TWC). Sensor signal in case of inertia fuel shutoff IMPLAUSIBLE [P0130] It happens when breaking with engine going downhill or in general when breaking with engine with high vacuum in intake manifold.. Minimum vacuum measured...

    2005 C180K MOT Emissions failure - advice sought - help!

    I'm sorry for reviving an old thread, but you gave me some hope. I have same problem with SLK200, M271 engine from 2004, already replaced half of the engine and now I'm facing ECU replacement. I'll try software update first :) Wish me luck... Edit: I feel I broke a record of time between...
