Today at MACTEC, we worked on a Mercedes-Benz W212 E-Class Bi-Turbo with a vibration and jerking issue. We inspected the driveshaft, identified a problem with the cross joint, and also checked the differential bushes, which appeared weak.
Alongside this, we worked on an Audi Q7 S Line for a performance package, including general engine tuning, brake service, spark plug replacement, EGR and throttle body cleaning, and a complete engine service using Mobil 1 oil and original filters and spark plugs.
