2012 X1 Converter Removal Update

Hi All,

Unfortunately no responses but had to get on with the job and subsequently reporting all went well … success achieved.

Here are the steps I used …

Elevate the vehicle front end (ramps or a lift) but keep on the wheels … this will be important at a following step.

Remove the two electrical plugs from the oxygen sensors at the rear of the engine valve cover. Requires removing cabin air filter, tray and support bars, engine cover, etc

Using a “Tow Eye”, install in place beside the oil filter cover and using a support from side to side bearing on the inner fenders, remove the RH engine mount nut from above and lift the engine slightly till it is up and off the mount (up 15-20mm). This step provides some of the clearance to extract the Cat.

Subsequently, from the underside, loosen the six bolts that attach the front suspension frame to the chassis. Remove the three bolts on the RH side completely.

Using a jack, lift the vehicle slightly and carefully from the RH forward lifting pad. The goal is to get another few millimetres clearance as the chassis lifts and the front suspension subframe and wheels stay on the ground. You now have sufficient clearance to remove the assembly over the subframe rearward.

Remove the RH motor mount to gain clearance (4 x E12 bolts) and then remove the bracket that secures the Cat and the clamp on the exhaust pipe. Slide the Cat rearward and be carful about the oxygen sensors as to not damage them.

Hope this helps.

Gus
