Hi, welcome to the club
All I can suggest is the two breakers I trust..
Adrian Bingham ( ade1122 user name ) and goes by seller ID ' BB autos ' on eBay.
Performance Peugeot - also on eBay
Sometimes they can be slow to reply but they are busy people!
2003 2.2hdi estate - mine 1998 Volvo 940 auto estate - also mine 2019 Citroen C3 something - the wife's PP2000 user, can help with faults / diagnostics in the Bournemouth area.
I actually tried Adrian and he got back to me straight away, he didn't have one but it worked out ok in the end.
I managed to get a replacement which arrived today, but I'm also going to repair the old one. I sawed the box open and it looks like all the issues have been caused by a single blown resistor on the board so someone smarter and less-colourblind than me is going to solder on a replacement.
That's odd, when the one failed on my 1998 D8 I tried to take it apart for autopsy but when I'd finally managed to saw the box open I found the circuitry encased in a block of resin - "Haha, you are, ow you say? Screwed."
