Thanks @T5-T6-Schnappi , I'm not doing a US to EU conversion. I live in the UK and have always been using the maps in the UK but let me try it now and will report back

I'm adding fault codes also. So the thing is... should I buy correct HIR units (I guess) or can I flash mine via vdash to work with EU headlamps or if not via vdash is it possible to do it via official vida if I'll found someone near my location?

@Libelix how did you install the tune? Flashing a tune doesn't do anything to the VCM.
Using the VOE adapter requires a computer/laptop that is able to run 2 seperate network connections in parallel. One towards the car and another towards the internet. Most non-business/home user devices from HP, Dell, Acer and so on don't support that.

Can you send me the link?
Thanks!

@Kurt1977 I think I'm getting old. 🤔

The official guide recommends cloning the software and than perform SRS configure. As your original module has a checksum error indicating corrupted software or a bad EEprom , cloning won't work.
You can try to just perform the SRS configure if you install a used module hoping the software is the same than in your original module or at least compatible with your car. If this doesn't work you will need an official VIDA subscription to perform a software reload, but this will only work if the software for the donor part is still present on the servers and if VIDA thinks the part number is somehow compatible with your car. Volvo has started to remove lots of softwares and part numbers for superseded/discontinued modules from their VIDA servers making software downloads impossible for those parts.

You can also try to contact some specialists for ecu repairs and ask them if they can fix your original module.

@Puppi

Hi, hat sich der Fehler bzw die Ursache in der Zwischenzeit aufgeklärt oder hast du (doch) mal versucht quer zu tauschen? Gab es noch weitere Symptome?

Mfg Tea

@T5-T6-Schnappi
Can it also be that the antenna amplifier is defective?

Maybe I have an incorrectly installed DDM module that affected the red CAN bus? But I tried with each option: #2, UE algorithm, and US algorithm. And in each option, the same message with a problem in the BCM software always appears.

@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.

@T5-T6-Schnappi it's working perfectly.Thank you!

@T5-T6-Schnappi Thanks for advice, i borrowed other cable and everything worked out. Also it works with different part/hardware numbers too( added picture). If it will be useful to anyone, it is enough to buy ETM by model year, the codes may differ.

@MarkusC30T5 Manuals don't have a TCM. So all related wiring for that can be removed from the car.
You need to ask the Vdash support if they can provide the required ECM reload (manual software) for you, and also if the configuration change in the CEM can be unlocked/activated for you.
This will of course cost you some money.
You also need to crack the CEM pin to change the configuration.

@Usturmaca Hier ist dir Pinbelegung vom SRS Modul.

Ich denke aber, du solltest es mal VIDA versuchen.
Mit dieser Option um genau zu sein.

Ob es diese Option auch in Vdash gibt weiß ich nicht. Wäre aber vermutlich einfacher falls du noch keine Erfahrungen mit VIDA.

@Jcm89 a flush every 10000 miles is a little bit over the top. Drain and refill at this intervall would be more than good enough to keep the transmission happy.

As for the torque limiter. 5-speed automatic is limited in the first two gears. 6-speed in first three gears, 8-speed has no limiter. This is done to reduce wear on the differential, drive shafts and several other parts, but also to have enough traction.
Some tuners offer to remove this limiter, but it has more negative than positive effects.

@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.

@Cookie_69 wrong forum for such questions. Vdash won't be useful for any of your questions.
Engines with Bosch throttle body require a different ECM. Those ECMs are not compatible with your CEM, so you need another CEM and somehow adopt it to your car. And so on.... Absolutely not worth it. You will basically need to update your whole car to the electronics of a 2005+ Model.
Get the correct engine for your car, or scrap it and get a new car.

I've discovered that the ideal auto show display stand should complement the size, design, and overall presentation objectives of my car. A strong, well-made stand gives the exhibit a more polished, safe appearance. I keep 24 Hour NYC Towing Services in mind for trustworthy roadside assistance whenever I need it, even as I focus on presenting my vehicle.
