Anyone familiar with disassembling the Carver DSP unit? Since i purchased the Z4 2 years ago, I've had audio issues below 10 degrees Celsius. During spring and summer, i can enjoy some nice music but in the winter, i get nothing. Didn't bother to look into it for the past two years since I really enjoy the music made by the M54B30 during winter. Had some free time and decided to crack open the case just to investigate the components and see where i can use contact cleaner.
I've gotten this far. Anyone knows of a safe way to undo these clips so i can take the whole PCB out?
For those that are wondering if it was water damaged. It has only been exposed to engine oil (noticed a pool of oil after i purchased the car. oops). If im not mistaken, oil should not cause any shorting issues right?
The DSP unit was submerged until the height indicated below.
On a side note, i know my GM5 module acts up in the winter, intermittent door lock reliability. Could this play a role somehow in the DSP not working? a year into my ownership, i would have to enable my rear window heater and play with the window switches, this then got the audio working. Doesn't seem to work this winter.
I'm not convinced that the engine oil has caused any damage however, i would like to get the PCB free from these clips to give it a good inspection. For now i've just sprayed the exposed PCB with contact cleaner as I have nothing to lose here.
below 10 degrees, while the engine is running i get a power supply fault code on the DSP, with the engine switched off audio works fine. above 10 degrees, no issues whatsoever regardless of engine running or not
