Hello,

I had the well known issue of total loss of bass on my car. All pointed to a faulty booster unit and i found a BMW service bullettin about the problem here in the forums, but since my car is out of warranty, i decided to try to change the booster my self, mainly because the price tag on the dealer was 1700€.

I tracked down a booster unit with the same part number that is mentioned in the SB, and i replaced the booster, but as suspected it will need some coding before it works.

I currently have bimmerutility and i can propably get esys also if needed, but i would need some help to figure out what needs to be done? TIA

The booster doesnt need any coding.

I know, but i think you have to code or flash the RAM, in order for the new booster to work?

Is it same replacement or different version? PM i can have a look at it remotely.

Different version. It is the version that BMW says to use to replace the original.

So far i have tried to just code the RAM with e-sys, VO code and to inject a new CAFD. Nothing worked so far.

Hi + DId you ever get this sorted, and what did you need to do in order for the new booster to work?
