Put the shelf battery in the car. Couldn’t tell a difference, but system voltage is running at about 14.5 VDC, which is a good thing.
Drove it a bit now that it’s legal. If it’s in LHM I could barely tell, as it had no problem accelerating and shifts were at the proper rpm/speed. Still idling high and surging at no load. ASR light is on still, too. Ran my C3 on it and got all kinds of weirdness. Communications failures, weird faults that don’t resurface despite not clearing anything, etc. I’m wondering if I’ve got something going on in the diagnostic connector, as the C3 worked fine on the R129 and W210 wagon, so I know it’s not goofy. There have been reports by other 400E and 500E owners about issues with corrosion in the diagnostic connector and all sorts of havoc it can wreak. Got the O2 sensor replaced. Wow, was that a pig. Thank goodness for three days of Kroil soaking…. Tomorrow I’m going to work on getting the lower body cladding back on with the new clips I’ve got. Not sure I have enough, but more are on their way. -D > On Feb 24, 2018, at 8:53 PM, Dwight Giles <dwight.gi...@gmail.com> wrote: > > Sounds like progress Dan.
