I believe I need to replace the fuel pressure regulator on the new to me 400E - it shows the same symptoms others note - initial starting is fine but when warm it will be difficult to start then stall, after a few minutes no driving issues at all. Anyway, my question is about cross referencing part numbers.
According to EPC the part number is A 000 078 18 89
From Fastlane and others I also get W0133-1609558 (Bosch)
I also found a cross reference of 0000781889 to Bosch 0280160587

A search on the Bosch part number gives by far the lowest price. Does anyone know if the cross reference is correct?

Thanks
Paul
