Occasional starting problem - getting worse

[Mighty306]

I'm not sure how easy it will be to clean up that multi plug as it looks like the plastic will have melted on to the contacts.  I'd be tempted to source a decent multiplug off a scrapped HDi and splice it in.  Then get a new relay as well - the fact multiple contacts seem to be affected would make me suspicious of the relay.   https://www.ebay.co.uk/sch/i.html?_odkw=...cat=131090  (Peugeot part number 19207L for an HDi as best I can tell).

Hopefully someone else will have a simpler fix!
