Car model and year: 2007 Benz ML350 with 186k Miles
56 DTCs and a leaking crankshaft seal.
Went through the DTCs and most were typical BS transient ones or very old ones, so I deleted them with my scan tool (Launch X431 ProS Mini), and only an SRS one returned in 200 miles of driving, so we’re good there.
What to do:
Please follow all the instructions to a t. If you do not, your engine will be damaged.
