P2033 Code 2007 Bluetec E-320
Sounds like someone erased the code and sold the car.
You get it drive it and the issue causing the code pops the cel.
Now you need smog and it won't pass.
Where in Ca?
Not familiar with the bt but if like most it is the sensor aft of the particulate canister
try autohausaz or peachparts
so if the egt is one of them the dealer won't argue they charge it back to mercedes.
PPI is pre purchase inspection
if one had been performed they would have discovered the code even if someone cleared the check engine light.
My GL has an underhood sticker cautioning against adding ANY QUANTITY of noncomplying oil. That obviously means a quart between changes, etc.
