Thanks all
Dave, the DK4 I have removed from the car was in good condition when checked with a strobe and I will retain it in the car as a spare. I haven’t checked the replacement DK4A yet but it definitely seems to improve things and the car runs more smoothly.
My research of E10 and it’s propensity to cause knocking is restricted to Google! Several web pages seem to confirm that higher grades of ethanol do cause knocking. Perhaps others will comment on the chemistry.
Marcus. It seems the only one of my three DK4A distributors that are definitely for the A7 is the one I’ve put on the car (top right in my earlier photo). Thanks for the info.
Once again many thanks
Howard
