@Vulpes did you do some live data readings while driving? If you see a constant barometric pressure of 1023 mbar regardless of the real outside pressure, you should check the wiring for brittle isolation and the connector of the MAF for corrosion and loose pins,and if they are ok, replace the MAF. You should also check for vacuum leaks, especially at the engine mounts.
Do you run the original air filter box, or some aftermarket cone filter crap?

Most probably incompatible/wrong HCM. What are the part numbers of original UK and the new headlights? And don't mention that you use orbit in the official vdash forum. That's a big red flag!

@spoonVolvo this adapter "should" work. At which exact point is vdash freezing? When you hit the diagnostic button or after you selected parameters? Vdash shows lots of parameters that aren't actually supported by the car it's connected to.
Did you create an exception for the (hidden) vdash directory (C:\Users{your user name}\AppData\Local\VDASH) in your antivirus? Some AV software like AVG, Avast, Norton heavily interfere with Vdash.

@Belos Did you receive a message/email that your pin code was successfully cracked and added to the vdash database?
You should always have a powerfull charger connected while you perform configuration changes. And after changing configurations, you should leave the car alone and locked for at least 15 minutes. What adapter do you use to connect your car and computer?

@spoonVolvo can't follow your link "This Item is not available in your region"
What name does Vdash show in the top right corner, when connected to the car?

@Vulpes have you "blanked" your EGR? And check/clean your MAP sensor. Do these errors appear with the original factory map?
D5T5 uses generic files from Obbe-Tuning. Custom tunes would require datalogging/dynoing.

@spoonVolvo what adapter do you use? DICE, Mongoose, Super J2534....?

@Viktor8989 programming keyless fobs needs the KVM pin which can't be cracked with vdash. Programming is only possible with an official VIDA subscription.

@Jer There is no ETA when AI decoding will be available again. If your car is modelyear 2005 or newer, get yourself a VDD https://d5t5.com/article/vdash-vdd-dongle or build a Teensy https://github.com/vtl/volvo-cem-cracker/wiki to crack the PIN.

@gubestiq Sounds like the Pedal is defective. Should be an easy replacement. You just must be aware that there are different pedals for manual and auto transmission.

@Mokama It simply is like this. You have done a modification which has some unavoidable flaws. It's also mentioned in this Wiki article https://d5t5.com/article/TFT-retrofit that DSTC can't be deactivated after doing this retrofit.

There is no adaption. Did you obtain these values while actually driving?

@skalaev Than opt for BSR tuning or RICA.

@skalaev enter your VIN in the search field on the D5T5 homepage and you will see all options possible. I think it should be possible for this engine.

@joroartcorp this should restore the original factory software of the DIM, so correct milage and no DTC.

There is no engineering mode in V40s. You need to crack the CEM and security PIN to disable ITP security and swap in a used localized IHU. https://svdns.info/2023/08/27/so-youve-bought-an-import-volvo/

The tuning potential of this engine is basically zero. At least if you aren't willing to invest insane amounts of time and money. Changing just the throttle body won't have any noticeable positive effect. As your engine is naturally aspirated, you would need to invest in machining your cylinder head, different cams, custom build exhaust setup with lower back pressure/better flow, custom intake setup, custom mapping, forged pistons and so on. Additionally you would need to get rid of serious amounts of weight. Buying a car with bigger displacement and a turbo charger is most probably the much cheaper option, and would give you way better performance.

Not possible. There are various OBD HUD displays for this, or countless apps for mobile phones like Car Scanner ELM OBD2, that just require an OBD-dongle like a vLinker MC+ or OBDLink MX+, and show all parameters that are provided by the ECUs that are installed in your car. Except oil pressure. Volvo uses simple oil pressure switches on most of their engines that switch on/off at a specific pressure value and give a warning when the pressure is below a specific pressure value. If you want to see absolute pressure values, you have to install an aftermarket solution for that.

@VladGB in this case you have the choice to visit a volvo garage and perform a software reload via an official VIDA subscription for the DIM. Or you have to create a support ticket and ask for help from the vdash devs. But you might need to crack your CEM pin to perform a software reload via vdash.

@VladGB I have newer seen this code before. This code means no communication towards the DIM and has no fault trace in VIDA, except check the DIM. And it is the cause for ACC not working.
Did you do any retrofits and/or configuration changes with vdash or P3tool?
