The updated version is this... SW Train = MEN2_EU_SKGPx_P0080L MU = 8755 If this helps you.

If you have a multimeter, then try to read Voltage after you have driven the car, and it has rested for 2hrs (ideally overnight) Unlock car, open bonnet and do a read, you would hope to be seeing 12.5V (with a little tolerance of that value) Or just drive the car, and monitor it for a bit to see if it behaves better now. Good luck!

Ideally yes just to speed up the "learning process" It has a battery monitor, as you can see hanging off the negative terminal top left (Stop/Start) Follow the guide posted, won't take but a few minutes. Brand can be JCB etc, doesn't matter Value that is important is "fleece" technology Amp Hour rating is "70" Serial number, just add +1 to value of last digit

It looks a lot better, did this clear out your errors on dash/infotainment system? Also the battery itself does still seem low (but diagnostic sessions will drain this) do you have image or details on what you fitted, and for bonus points, what was fitted before battery swap?

Here is some more background information for the post, there is a "triple" software package that is detailed in FIRST, SECOND and THIRD. The FOURTH package is a standalone update. FIRST "Release": "MOI3_EU_SKMQB_R23802P", "MuVersion": "0238", "SupportedTrains": [ "*_?133*", "*_?134*", "*_?136*", "*_?137*", "*_?138*", "*_?139*", "*_?140*", "*_?141*", "*_?142*", "*_?143*", "*_?144*", "*_?145*", "*_?146*", "*_?147*", "*_?148*", "*_?149*", "*_?150*", "*_?151*", "*_?152*", "*_?153*", "*_?154*", "*_?155*", "*_?156*", "*_?157*", "*_?201*", "*_?205*", "*_?207*", "*_?208*", "*_?210*", "*_?212*", "*_?214*", "*_?216*", "*_?218*", "*_?220*", "*_?222*", "*_?224*", "*_?226*", "*_?228*", "*_?230*", "*_?232*", "*_?234*", "*_?236*", "*_?238*" ], As you can read, this does support the 0156 version, and then should update you to 0238 at the end. SECOND "Release": "MOI3_EU_SKMQB_P26810P", "MuVersion": "0268", "SupportedTrains": [ "*_?238*", "*_?240*", "*_?242*", "*_?243*", "*_?244*", "*_?245*", "*_?246*", "*_?249*", "*_?251*", "*_?252*", "*_?254*", "*_?256*", "*_?257*", "*_?260*", "*_?262*", "*_?264*", "*_?266*", "*_?268*" ], THIRD "Release": "MOI3_EU_SKMQB_P27800P", "MuVersion": "0278", "SupportedTrains": [ "*_?268*", "*_?270*", "*_?272*", "*_?274*", "*_?276*", "*_?278*" ], FOURTH "Release": "MOI3_EU_SKMQB_P30603P", "MuVersion": "0306", "SupportedTrains": [ "*_?268*", "*_?270*", "*_?272*", "*_?274*", "*_?276*", "*_?278*", "*_?300*", "*_?302*", "*_?304*", "*_?306*" ], Technically you can skip the 3rd update, and go directly to the 4th one.

You may want to adapt the battery if you have not already done so?

I do not have 0245 version, only 0252 @pab567 Do you have any older version saved MST2_EU_SK_PQ_P0245T?

I will send you PM

Lot's of low Voltage errors, are these all "fresh" faults in the car? Have you cleared faults and see now what remains?

Pull the codes out of the car with these tools, VCDS is best bet. Post the log (erase your VIN if you prefer)

That will most likely be down to the software changes, you might have to reach out to Rosstech if you are using VCDS and a genuine head, they might have a different coding to offer you. Other choice is dealer/indepentant and to do an online coding change on the part so the factory can generate the correct coding (in theory)

You would be fine doing the update from 0304 to 0306 via OTA upgrade. The OP's issue with Nav comes from the upgrade from a very old firmware 0156 to 0306 and the intermediate firmwares applied.

@krisopl @omide Sorry I missed your posts, did you still need firmware updates?

News to me... only seen 0480 so far.

Perfect 🤝

Another guide for you to absorb, was a bit busy and only just posted. Hope it helps, and plenty of forum folks will assist with questions on wiring diagrams.

Thanks for the write up of this for others to follow. I am sure there are others out there on older versions, and looking for an upgrade path. I look forward to the next chapter, of getting the activation code input 🤝

If you can burn a CD-R, then I can supply you the update or @pab567 but we do need to know what version of the firmware you have now. You will be best if you can pop the head unit out and get a picture of the label on the top.

No you cannot just load MIB2 software. You might be able to swap over the full hardware and try and fit a MIB2 unit, but this might not be 100% compatible with the car's other software/functions. @pab567 Might be able to answer if this will be a good idea to perform or not.

Start looking for an independant workshop, ask if they have ODIS and can remove CP from your part.

You can get a small bump to 0253 via PM

If the project cost you £200 (2nd hand parts let's say) and you save £1 a week in fuel... it would take 4 years to break even. I do have a Greenline, and it can post some incredible figures, but always depends on how it is driven. You might be better off keeping a close eye on tyre pressures and servicing, driving with windows up at higher speeds (if you don't already) etc.

I will send you a link via PM

The 2nd fault code is the very common one that occurs when you do not have online connection to factory. Easily fixed, https://forums.ross-tech.com/index.php?threads/18798/ The 1st fault code might sadly need you to go online to make a possible new coding of the unit (though so far no one has complained of loosing function!) So you maybe wise to test all things on the system to check out each function is intact, and maybe no physical errors are seen, so you can then ignore the coding change.

Yes you can have 0490 version in a few moments.
