Hello,

I need assistance on two different cars. First, I have a 2008 E350 that shows an F Service past due 1150 days (and counting) indication every time I start the car. I have tried every clearing procedure I can find and in every instance the result is “service not confirmed” and the warning remains. I bought the car used and when the B Service came on I cleared that without a hitch. But now this past due F appeared and will not go away. What do I have to do that I have not already done by following every instruction that I can find?

Second, I have a 1990 300se with a 722.3 transmission and I want to install a new modulator. Searches reveal any number of rigs to check to pressure. I have plenty of pressure gauges and all I need is a fitting. I would like to order a banjo fitting but I do not know what size is required (M8x1, M10x1, etc.). Does anyone know?

Thank you for any and all help.

Lloyd
