I have read on here about the purge control valve and replaced it12 months ago, and when it was going through the overheating stage in 2020 before I had the HGF in early 2020 I replaced the coolant temp sensor just as a matter of course.It has been on a couple of short trips and started ok and on return I check plugs they are dry and no oil in the spark plug wells. Yesterday I fitted new coils and leads, as usual everything possible comes from DMGRS so no inferior parts used.This morning it struggled once again and coughed and spluttered ran for couple of seconds then stopped and the only light that came on dash was the battery light and that went out when I attempted to start and it caught this time.The battery was fully charged thursday and on test is holding it`s charge. When it is on the road it doesn`t drive any different and it does still start first time when engine warm. No smoke visible from exhaust and on tickover it behaves no differently. Occasionally the EML would come on and on the OBD scanner it would be PO420 catalyst efficiency below threshold ( Bank 1) and have used cataclean and it doesn`t show again for some months, and as today it shows up no errors. So do you folks have a diagnosis I wonder ? All though I will probably still have to take it to the garage I feel I need to have a rough idea before I am fleeced as I have been several times before ( not just with this car) and am no mechanic, just know the basics really, any advice as always appreciated from you knowledgeable folk,regards Paul

This may sound like a stupid suggestion, Paul, but have you checked that the plenum is dry?...You've checked so many other areas and still have a problem starting, so perhaps it could be something a simple as a damp ECU playing up. ( well not actually "simple" as such but you know what I mean)
