Hi folks it seems that this relay is responsible for a ton of problems, but does any one know what the actual failed component in the relay is? I have recently had the fuel pump control relay replaced on my 300E (£109.00 in the UK.) I have the old one back and will try and find out the failure cause. There must be good number of Electronic Techies out there that have done this exercise before.
