Dont want to wake up old thread or so , but is it also possible to put brand new CEM facelift variant to 2014 car which does not have it. V40 also.

And can KVM brand new be equipped as retrofit ?

Using VIDA or here someone in D5t5 does this with used modules ?

@Bartas222 the factory configuration for iTPMS looks like this.

After changing any parameters with Vdash you have to shut down the car and lock it for at least 20 minutes to make sure the changes get properly applied.
The tyre monitor should be visible as seperate menu under "My Car".

@Bigv Do you have a check engine light now? This would mean there is another problem with your engine. Checksum errors don't trigger the CEL and can be ignored as long as the engine starts and runs without problems.
I can't help you with VIDA. Subscriptions for legit VIDA are only available for private users in the US, while I live in germany. Cracked offline versions like VIDA2014D are not able to do software reloads. Your tuner should have made a backup of your original software and should be able to restore it.
Reverting to stock software would also require to remove the blanking plate as the EGR would be reactivated.

Got the air con repaired. There was a wiring fault.

Hello,

Did you get this figured out?
I'm going to need to do this shortly, and I'm curious if VDASH can actually clear this, everywhere else you need to bench it and clear it.

Thank you mate just did that hope you guys can help Im kinda desperate at this point 😅

@reeferjon What did you use to get this code? That's no Volvo/VIDA format. And that P200500 code is not present in VIDA for the ECM of your car. Scan the car with Vdash or VIDA.
Vdash is no diagnostic software. You can still try live data reading via the ecu diagnostic function of Vdash, but you will need to use a Super J2534 adapter or a really, really good DICE clone for this. Other adapters are to slow for this.
There should be at least 3 different ECM values that you can monitor. Demanded throttle position, and two values for the 2 sensors. Demand and sensors should show similar values.

You can also use VIDA, which you can get in the depths of this forum, and perform a throttle activation via the ECM to test it's function while the engine isn't running. I'm not sure if Vdash also has that function, as it is not made with diagnostics in mind and therefore lacks lots of such functions.

As your code seems to be airflow related, have you already checked your MAP sensors? Like this? Your car has two of these sensors. One in the plastic pipe between the throttle body and the intercooler. And one as shown in the article I've linked. Both tend to get clogged and create lots of codes like MAF errors or low airflow codes.
If there is lots of carbon buildup on the sensors, cleaning the throttle body and MAF is also a good idea.

Ach stark ☺️

Danke dir schonmal für die hilfreichen Tipps.
Wenn ich aus dem Urlaub zurück bin, werde ich direkt das CEM checken und die Steckverbindung an der A-Säule höher der Klappe des Handschuhfachs hinter der weißen Abdeckung.

Werde mich danach nochmal bei dir Rückmelden.

@330hpwagon I'm not sure if your car supports HDC. The official manuals mention HDC only from model years 2015.5 onward as this feature was officially introduced with the Cross Country models and is activated by default on these models only.
To use HDC you have to manually shift to 1st gear or R. You can't activate it when in D or above 7 km/h.
VIDA doesn't mention anything about specific hard- or software that has to be installed or that this function is only available from a specific structure week like other functions like ERS.
The DTCs in your BCM are also all yellow which means they are temporary/historic/not active while the others in red are permanent. The first one in the CEM is from LED bulbs at the license plate and can be ignored. The others should be the ones that you want to adress.

Why exactly do you even want to activate this function? I have a V60CC with this function and never felt the need to go downhill with less than 10 km/h.

@VolvoAugust The only way to get the pin is on the bench. You won't get information how to actually do this in this forum. The guys that know how to do it, usually don't share their knowledge to the public.

Thank you so much for your answer! I was told that and it was werid when I saw the message in vdash.
I will contact the vdash support, maybe they can help me with this issue.

I would suspect a defect wheel speed sensor, corroded sensor ring at one of the wheel bearings, or low battery voltage.
Put the car on a lift and check the signals of all sensors with an oscilloscope. The sensors could still be working, but the sensor rings could miss one or more teeth which results in sending nonsense signals to the BCM.
