We will carefully check if the chassis number on the windshield, chassis, and door frame matches.

We will honestly inform you of the common issues with this model (such as the water pump failure in certain German cars) and show that this car has had the improved parts replaced.

Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.
