As stated, looking for a diesel tech/shop, van is out of warranty so can go anywhere now. Thanks for any pointers!
I bring my big trucks to Chapmanās garage in Conley - not sure if they do work on the sprinter but worth a call . One of the few shops that has always done exactly what they said in the timeline they said .
Thanks for the advice on Chapman's. Doesn't matter where in Atlanta. Could be N Ga anywhere. Or Alabama/SC for that matter.
