Hi guys I got a BMW F02 2009. The heated seats buttons are not working or lighting up, I have tested & activated the heated seats via ISTA+ & they are warming up fine. I checked IHKA & it was missing CAFD & have tried several times to inject the CAFD but it throws up a error . Anyone came across this issue before?

So far I have updated the i-step to the latest & still it won’t allow me to inject the CAFD into IHKA.

Thanks in advance

Is your VO correct?

Is your VO correct?

Hi yes the VO is correct.

[jaramillo]

Post your error

Here are the errors I’m getting from ISTA scan and also the a WARN event warning is coming up when I connect to the car & then click on read ECU & the Caf’s Suchen is the errors I’m getting after the CAFD has failed to  inject.

Is IHKA correct for your car and match VO? WDBI_plain error usally means that something in equipment does not match VO

The IHKA has definitely been replaced by someone as I can see the that it’s got sticker on the back of it from the spare parts/car breakers yard. I have checked the BMW part number that’s on the back of the IHKA but it doesn’t match any part numbers that are stored on bmw database so it is possible that it may be the wrong version but usually there are only 2 types of IHKA’s Basic & High & only other difference is heated or none heated seats.

I have tried a few other IHKA’s panels, they all doing the same thing. The heated seats work when I first plug in the IHKA but soon as I try to code it, it stops working & I get them errors.

You are SERIOUSLY wrong if you think there are just basic & high IHKA. Each of these have MANY sub-types which were mounted depending on car options.

According to VIN in your printout (if there are no retrofits) you need 9202587. ETK shows part numbers for parts SOLD AS REPLACEMENT ONLY!!! Those normally have less sub-types as they have support for many different option sets.

Why instead of being TOO clever and completely wrong won't you tell what part #s you have so someone (maybe me) can check if they fit!?

There will be other part #s which could also fit based on same hardware but with newer software.

Alternatively you could modify VO so parts you have could be coded, but of course you will have issues with something not working or there being faults for missing hardware. Others could be FDL coded to work properly.

Some older/newer part #s which could (found using db query, but have not checked that all of them really do) fit your car: 9194364, 9199869, 9212460, 9208549, 9216254, 9218405, 9221088, 9224747, 9229817...

Thanks for the advice & information you have provided but most of what you mentioned, I already know & checked/tested before posting on here, for this specific car F01/F02 there are only 2 versions of IHKA as it being a F02 750LI long wheel base model, they all came FKA with 4 zone control but yes for other BMW models there any many different versions & part numbers of IHKA based on cars spec.

Again no is trying to be TOO clever or completely wrong here. No one asked me for any part numbers & just to make it clear I have more then 10 IKHA panels & the part numbers that are printed on the back do not show up on ETK, RealOem, Bimmercat, not even BMW dealers can find these parts number on their database of these used IHKA panels I have in stock but if you want to check, I will send the part numbers to you tomorrow.

According to the cars vin number BMW dealer confirms only these 3 part numbers fit this car: 61319328413, 61319290732, 61319221654 but there is no way to confirm if these parts number are compatible to the one in the car already or to the ones I have in stock as none of them show up on parts catalog back when checking the part numbers printed on the back of the IHKA.

The car doesn’t have any retrofits, it’s completely factory, all other switches work fine on the IHKA but only heated seats switch off & ideally I want to make it work with using the correct IHKA panel so I will continue to look for the correct part & test with that.

PS. I only asked on the forum to see if someone has experience this issue before as I have retrofitted 100’s full spec electric memory & heated, ventilated, massage seats with various different specs into BMW’s & never came across this issue where only heated seat buttons don’t work but everything else works is fine.

Thanks anyways much appreciated.

And again your are TOO clever and COMPLETELY wrong. I have looked into KIS database and for SPECIFIC type code of your car KB82 there are like 7 or 8 DIFFERENT IHKAs mounted from factory depending on car options!!!

As I already told you, your dealer can only "confirm" the part #s which were SOLD as replacement parts!!! Most of IHKAs installed in the factory when BUILDING CARS are COMPLETELY DIFFERENT than those sold as replacements. For replacement parts BMW does not want to have several hundreds of different IHKAs in stock, so they sell like "top" IHKAs with most features available. When building cars they can save a bit of money if they install just the right IHKA with just the option set required.

So the numbers printed on the back of IHKAs are completely and perfectly CORRECT. And ESys USES them when determining proper CAFD. If the IHKA does not match car options, you get WDBI errors. Your problem EXACTLY.

So on the second hand market you will see most parts which are REMOVED from cars where they were installed WHILE BUILDING cars at factory! And most of times you will NOT find them in ETK or at dealer...

So if you are so arrogant as to think that dealer knows it all and people here do not, why bother asking questions here at all???

I have spent good 30 minutes sifting through part #s of IHKAs for YOUR CAR SPECIFICALLY and wrote you a list of part #s which were installed IN FACTORY for SPECIFIC options of your car. But again, it's up to you to if you will be humble enough and use that info. I'm done.

P.S. SAME with other electronic units, not just IHKA.

Oh but there IS a way. Just not the dealer way. You just don't want to accept the help on that. I (and probably some others) can tell you EXACTLY what car options each module was installed on by it's part # (of course parts with firmware only contained in KIS).
