@Gir known issues are listed at the end of this guide.
And you need to use a DIM with white back cover and from a donor car with automatic transmission. DIMs with black back cover (from cars with VEA engine) won't work in your car.

FSM Code

T5 T6 Schnappi — Sun, 07 Jun 2026 14:24:05 GMT

@akeker first of all. You have lots of low voltage errors. Replace both batteries first and perform a BMS reset afterwards.
To calibrate the FSM you need to drive the car for a while on a road with clearly visible markings and at good day light conditions after starting the calibration. That's it basically. It's also possible that your front radar needs a realignment.

@T5-T6-Schnappi Ich habe eine Batterie der Marke Bosch bestellt. Die Batterie wurde getestet und ist zu 100 % geladen, der Ladestand wird jedoch mit 86 % angezeigt. Ich melde mich wieder, sobald die Batterie eingetroffen ist. Vielen Dank für Ihre Aufmerksamkeit.

V70III ICM bricked during language change/flash

mrgrog — Sun, 17 May 2026 18:08:13 GMT

Update to close the topic - since the ICM was responsive, I got a package prepared by d5t5, flashed it again (with German as base language for some reson) and then successfuly flashed to correct language. Happy ending, now I have a spare replacement module.

Headlamp failure

T5 T6 Schnappi — Tue, 12 May 2026 16:08:56 GMT

@Nirp Do you install everything according to VIDA/EWD? Additional wirings, HCM, level sensors, light switch, and so on. Or did you just swapped in the headlights. What option in Vdash did you select and what DTCs do you have?

possible to Sync IMMO and ECU on S60 II Denso ECM-U042600

RobinPe — Thu, 30 Apr 2026 09:33:35 GMT

@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 🙂

Remote Start Fail

T5 T6 Schnappi — Thu, 19 Mar 2026 12:15:14 GMT

@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.

T5 T6 Schnappi — Wed, 04 Mar 2026 12:19:02 GMT

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.

@Usturmaca simply ask everything that is unclear. What do you want to do after you decoded the CEM?

I want to teach in after air compresor and valve block was changed

T5 T6 Schnappi — Wed, 18 Feb 2026 17:23:54 GMT

@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.

V40 D2 - Bricked DIM after failed flash

ismaellj — Wed, 11 Feb 2026 13:06:36 GMT

Hi,

I accidentaly flashed my DIM using P3Tool. Now it is bricked.

Part number is 360100135.

It's a Volvo V40 D2 Powershift 2015.

The D5T5 was king enough to use a backup to reconstruct the file, but I'm still waiting on them.

My question is, what process should I use to restore it, once I get the file?

I also ordered a used DIM with the same part number. It has around 180 000kms, while mine is at around 111000 kms.

Any toughts or tests you can recommend?

Thank you.

V60 2015 hybrid charging problems

Vizual54 — Sun, 18 Jan 2026 09:37:58 GMT

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.

Problém s odemykáním kufru na XC60 2015

Josef- XC60 — Fri, 16 Jan 2026 19:25:35 GMT

Prosím, mám problém s odemykáním kufru, mám verzi s manuálním otevíráním, takže mě trápí jen ten odskok zámku, tlačítkem na klíči a na přístrojové desce to nejde vůbec a na kufru občas, mikrospínač změřen, v pořádku, kabely mezi zámkem a konektorem vlevo v kufru taky prosvícený, v pořádku. Při odpojení zámku je občas slyšet sepnutí relé u nohou spolujezdce, na připojeném multimetru konektoru je to i vidět. Odhaduju řídící jednotku. Byl by někdo ochotný odhadnout cenu, popřípadě vyřešit? Děkuju

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...

V60 DIM/climate control panel problem

T5 T6 Schnappi — Sat, 10 Jan 2026 20:30:49 GMT

@Oleksandr1540 DIM-U300045 is the result of milage manipulation. Vdash should provide a software reload to fix this. Just connect your car to vdash and click on the DIM. There should be an option to perform a software update/reload. Use a Mongoose JLR or Super J2534 adapter for this. Don't do this if your adapter is a Vxdiag/Vxnano, or you will brick your car.
