Hello, sorry for the late reply, odometer says 189k km which I've checked both with vida and vdash, don't think it's been used for towing. Only today could I find the opportunity to crack the level plug, I'll upload a picture of the fluid on a bit of paper - looks bad because some filth from the undercarriage wiped away onto the paper. DEFINITELY due for a change (which means the previous owner lied about changing it) but somehow it smelled the same as my jug of Aisin ATF 6, zero off-smells or anything of the sort. Is a professional flush the way to go now or is a drain and fill safer and see where we go from there ? (I have to use an imgur link since it's barely over the attachment size limit, sorry) https://imgur.com/a/sjmVtUG

Late here but a spacer installed on rear 02 sensor is a common USA hack when catalyst is setting codes.
The idea is to get rear O2 out of exhaust stream to try to even out the voltage swings that signal cat isn't working. After putting a spacer in, rear O2 volt swing is greatly reduced but average voltage is usually slightly higher than I would normally expect (.7 to .8v)

When I have tried it on SI6 cars (turbo or NA) they usually start to set rear O2 codes. I am guessing these cars use rear sensor for a secondary fuel trim check and not just looking for a flat line signal around .6v to prove cat is lit and working.

Anyone? I can't be the only one interested in this right?

@T5-T6-Schnappi Ich brauche den Schaltplan, zeigt, zu welchen Pin-Nummern am SRS-Airbag-Steuergerät der auf diesem Bild gezeigte Sensor führt.„Oder ehrlich gesagt weiß ich nicht, auf welches von den grünen ich mich konzentrieren soll.

@Metsavend What excactly is your expectation after changing the CEM? The CEM of the V40 seems to be the same for all model years 2012-2019. Vdash should be able clone these to new or virginized CEMs if you have the write protection and IMMO pins of your old module.

Retrofitting keyless entry should be possible, but it's a hell of a job. Your car is most probably not prewired for this, so you have to install all the missing wiring. Also all the antennas needed and the door handles. then you can either install a used compatible module after extracting the KVM IMMO pin on the bench from it and adding this pin to Vdash. And hope that there are no other VIN specific codings needed to use it in your car. You will just need to change the CEM configuration with Vdash and should than be able to program keyless fobs to your car. But I cannot guarantee that this will work.

Or you have to talk to a Volvo dealer if he orders the configuration changes needed and also the software packages to programm a brand new KVM module and keyfobs to you car. This is most probably not possible with a subscription for private users as you need to be SERMI or NASTF VSP registered for IMMO/Key coding with VIDA. There might be independent Volvo repair shops with the required license and VIDA subscription level, but you will pay the same or even more than at an official dealer.

@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.
