Congratulations for finding this issue. That's really an unusual one.

I really don't want to be that guy, but you still should be concerned what is the real problem with your car. Why has there been a spacer installed, which would never be necessary on a healthy engine? And what caused that amount of carbon buildup to block it? This is definitely not normal. Your engine is either burning too much oil, has one or more bad injectors, low compression from worn piston rings and/or burnt exhaust valves, or you are simply using bad quality fuel. Or something else I currently don't think of. Whatever it is, your fix is most probaly just temporary.

@T5-T6-Schnappi every thing else is working fine so far.
Battery dead, secondary battery dead, some DCT here and there after a year of an ECU dropping 200mA in Off-State.
But every other Unit is answering Fine.

And thanks for the Adresse, contacted them 🙂

@johnzero 5 cylinder Diesel = ECM pin reading on the bench required.

@pamie849 that sums it up. The official description doesn't mention anything about that. https://d5t5.com/article/scu-pair

Car is finally charging its batteries again on the land line.
After a lot of investigations on what chargers would fit the car, there is a bunch of different part numbers on the OBC for the v60, I ordered a used charger from the scrap yard. Internally and communication vise they should be basically the same and are interchangeable. However there are different lengths on the cables. My charger had the number 30659929 on it, but the one I ordered had the number 32202164. Turned out the AC cable and the cable to the DC/DC converter where shorter on the new charger one so I just swapped the lids on them. After resetting the error codes the car is now on the drive way charging its batteries and is soon ready for test drive.

It got to decode the ECM took about 48 hours luckily

@Prinz-Bernhard complete hardware change needed.
Here is little lecture about it. https://svdns.info/2023/08/27/so-youve-bought-an-import-volvo/

Greatings from the south of Berlin. 😉

It works for now.
It would be nice to be able to save the read parameters to a file (.txt or .csv). Is this possible?

@volveeta After changing parameters, you have to shut off the car and lock it long enough until all ecus are fully shut down. This can take up to 20 minutes. After that time all changes made "should" be active and in effect. For the first ERS attempt, you should drive around for a while and then leave the car locked and alone for a short period of time. If ERS is actived, but still not working, there usually are messages on the dash, which prerequisits are not okay. The car should be parked on halfway level ground, battery SOC over 80%, enough fuel in the tank, parking brake applied, no active DTCs in the ECM and TCM.
If you press any key on the fob, after the ERS is triggered, the car is immediatly shuts off.

BMS reset is only needed after replacing the main battery. The support battery has no sensor.
In your case simply do nothing. The battery management still adapts to the new battery, but it takes a little bit longer to be correct. Nothing to worry about. The BMS reset resets the battery timer, which is the only way to precisly tell the age of the battery or at least when it was installed in your car, and also tells the battery management to adapt to a new battery. This should never be performed without actually replacing the main battery.

NO, no DTC's that is why I was presuming that something is wrong:)

@Usturmaca simply ask everything that is unclear. What do you want to do after you decoded the CEM?
Ich spreche übrigens auch deutsch, falls dir das lieber ist. 😉

@LIVIU1995 Is the new compressor working? Did you delete all DTCs after installing the new parts, and did they all disapear? As long as you just changed the compressor, there shouldn't be any calibration needed. If you didn't damage the leveling sensors, you should simply start the car, enable air suspension and drive a little bit.
If Vdash doesn't show advanced options for specific ECUs, those functions are either not implemented jet, or your account isn't unlocked to access them. "sponsored" accounts for example, don't have full access to all functions. You could also try a mobile phone app called V-Tool https://v-tool.app/ in combination with a vLinker MC+adapter. This app is similar to Vdash in terms of diagnostics and service functions, but seems to support more functions on some cars.

@Theik My 2011 XC70 has the power tailgate but like yours it does not lock via the IOS APP. Strangely my tailgate does lock when commanded via the web interface on here or of course with the keyfob. There appears to be a bug in the IOS APP.

Unfortunately, I no longer have the original DIM

I think the problem is in the red section describing the missing VGM/firewall key which is missing so VDash can do basic diagnostics only. But I might be wrong, as the screenshots are from XC90, and you are talking about S60...
