BPGA testing?

Post by dram773 »

Hi all,
Last month I replaced the BPGA on my 2017 308sw. So far, all is well.
But I was wondering if it is possible to test the old unit to trace the fault(s) - probably the relay?
Can anyone suggest a methodology?
Many thanks

This video is a start if you know Spanish to understand how BPGA works. The "relay" let's say is embedded in board and maybe it's similar to yours.Very hard to fix it. It"s not like BSI where at least even if it is hard, you can change the relay of pump for example, by removing the resin pack.Very common fix in Russia if you search YT because of lack of parts.

Thanks for the info. As you say, looks like a challenge - and beyond my limited abilities!
