c230 Kompressor P1235, PO 170, PO301
and another thing, today, when i was just cruising down the road in drive, it all of a sudden acted like it was in nuetral, but was making a grinding noise from the shifter/transmission. i wasnt trying to shift it or anything, just in drive. i put it in neutral, then put it back in drive and it seemed good again.
any help will be very appreciated!
by the way, i have reset the codes with my scanner, and they came back almost immediately after start up.
