Spot on! I told him exactly that. They'll fix the DEF metering and then we'll see. I was reading up on the glow plug issue and it doesn't seem logical to me to change the GPC if there is only one that shows a code.

And no, I won't hand over 1200 dollar for that job, that is outrageous. Anyway, I did my own AT rebuild and the V-pan gasket on the e53. I have a feeling I can manage the GP change as well. (It does seem there is some prep and forethought needed to avoid shearing them.)

One rear airbag on occasion sags, I bet they'll spot that one in the morning.....

I am just reading uphow to get going with INPA, etc.
