    C250 CGi Alarm siren sounding but alarm not triggered!

    Just seen this so apologies for delay. It's inside the front left wheel arch. You need to remove the rear section of wheel arch liner and you will see it bottom left as you look at the car. Hope that helps.

    B002113 The squib for the left windowbag/headbag has a malfunction. There is an open circuit.

    I am trying to help a friend who owns a W177 A Class that has thrown this fault code. Looking with Xentry I can see this open circuit fault has been picked up twice in the last week or so but not previously in their ownership. The car was delivered new on 1/4/2019 and was purchased at about 8...

    Fault Code 912749 The air quality sensor has a malfunction. There is an internal electrical fault.

    Sorry did not spot your question. No it's still not fixed as I haven't found the sensor yet! Even did a text based search of WIS for my VIN and it is totally silent on instructions to replace it. As far as I can see unless you drive through long tunnels or in heavy smog conditions it's not a...

    Installation of Android Auto/Apple Carplay with COMAND NTG4.0

    Lessons Learned installing a LIMCET Apple Carplay / Android Auto Box with NTG4.0 The large number of YouTube videos are a fantastic help in terms of getting the car apart and how to complete the installation work. However, do not assume everything you see will apply to your car and...

    Installation of Android Auto/Apple Carplay with COMAND NTG4.0

    Amazon came up with the goods and all now working as it should. I just need to put the car back together. When I get time I will put together a short "Lessons Learned" in case it helps someone else. So far at least I am really impressed and especially as it works wirelessly for Android which I...

    Coding?

    Wow interesting discussion. Of course you can also change the coding accidentally in you fit a second hand module or even a new one and it isn't recoded to car spec. There's lots of examples on the net of people replacing an alarm siren and finding it now chirps on lock and unlock where it...

    Installation of Android Auto/Apple Carplay with COMAND NTG4.0

    BTW I have just tested that the internal microphone is working OK. There is another 3.5m jack plug at the "box" end of the new harness labelled MIC which goes into the MIC socket on the box (obviously!). Well when I select the microphone in Android Auto my words get picked up and put into text...

    Help appreciated with "P009564 - Intake air temperature sensor 2 (cylinder bank 1) has an electrical fault. There is an implausible signal."

    Yes I think you are quite correct. I stupidly thought I had done that but given how cheap it turned out to be I now don't think it was genuine. I just wanted to get it sorted and the quickest option for me was to pop to main dealer. As for the gasket I was just following the WIS instructions...

    Help appreciated with "P009564 - Intake air temperature sensor 2 (cylinder bank 1) has an electrical fault. There is an implausible signal."

    Thanks for the reply. Yes I looked at these two sensors in EPC and for my VIN at least they are two different part numbers and 400 is listed as just a pressure sensor. Anyway today I can report that I have replaced the cheapo Amazon part (the one labelled 420 under the EGR) with one from my...

    Help appreciated with "P009564 - Intake air temperature sensor 2 (cylinder bank 1) has an electrical fault. There is an implausible signal."

    Thanks for the reply. I did a physical wiring inspection first and didn't see anything obvious in the way of damage or corrosion. I will definitely investigate that a bit more and also see what I get if I just unplug the sensor. Also I will poke around in xentry to see what I can find in terms...

    Help appreciated with "P009564 - Intake air temperature sensor 2 (cylinder bank 1) has an electrical fault. There is an implausible signal."

    I have spent more time looking at WIS and EPC and this is the looks to be the only temp sensor on the air intake plus the WIS page to remove install is entittled "AR09.41-P-2002ORA Remove/install charge air temperature sensor". If nobody has any other suggestions I guess my next move is to...

    Help appreciated with "P009564 - Intake air temperature sensor 2 (cylinder bank 1) has an electrical fault. There is an implausible signal."

    So the EML light came on a few days after the MOT on my wife's 2017 B180D fitted with the OM607 Engine. I hooked up Xentry and got a current and stored fault of P009564 Intake air temperature sensor 2 (cylinder bank 1) has an electrical fault. There is an implausible signal. So I duly ordered...

    C250 CGi Alarm siren sounding but alarm not triggered!

    "Or maybe the old one has such a fault and the newer one just needs to be coded to sound (I will connect up Vediamo over the weekend and see how the coding compares to my saved coding)." It was exactly this. Once coded correctly in Vediamo all is fixed. Odd that the faulty Siren doesn't throw...

    Can anybody help with a fog light part number?

    Just to close out this thread I have now put the left fog light back in the car with a new H8 bulb and all is good for now. Just need to (carefully) change the bulb in the right hand one. I have spent hours searching the web for aftermarket ones like mine with much luck. The closest I have...

    C250 CGi Alarm siren sounding but alarm not triggered!

    My replacement (used) Siren duly arrived and this afternoon I swapped it over and gave it a test. The result was somewhat disappointing in that the car behaves just as it does with the old siren. i.e. No lock/unlock chirps and no siren when I trigger the Alarm by opening the drivers door with...

    Can anybody help with a fog light part number?

    Thanks for the replies which seem to confirm my suspicions. Looks like it's just new bulbs for now and hunt out something better (original MB) later.

    Can anybody help with a fog light part number?

    I posted elsewhere in another thread that I had an issue getting the bulb out of the left fog light in my 2009 C 250 CGI BlueEFFICIENCY. Today I have removed the screen wash reservoir to gain access to attack the issue and eventually managed to remove the fog light from its housing in the front...
