LOUD SQUEALING AND/OR GRINDING NOISE WITH LACK OF POWER IN R50 R52 R53 CHASSIS

The most common culprit for squealing and grinding noises in these vehicles is the harmonic balancer failing and coming apart. The squealing and grinding are a result of the outer ring slipping on the inner ring of the balancer. If driven this way can also lead to the outer ring of the balancer grinding into the lower timing chain housing causing more damage.

INSIDE DOOR HANDLE NOT WORKING

The inside door release handle cable becomes dislodged from the latch housing due to its design. This can be repaired by putting a piece of friction tape on the cable and placing it back into the latch housing.

SLOW COOLANT LEAK ON ALL MINI COOPERS

The plastic thermostat housing on the engine warps over time, causing a continuous but slow coolant leak. The appropriate repair is the replacement of the housing and thermostat. Be careful, there are a lot of aftermarket knockoff thermostat housings available, and we have seen many cases of other shops using cheap housings which leads to customers coming to us for a coolant leak from their “newly” replaced housings.

ROUGH RUNNING, LOUD RATTLE AT START UP IN N14 TURBOCHARGED COOPER S MODELS

Oftentimes, the timing chain tensioner is “not extending” far enough (according to MINI) to maintain tension on the timing chain. The correct repair is to replace the timing chain with guide rails and tensioner. While not a trivial repair, if left and not repaired in time the timing chain can jump timing allowing the valves to collide with the pistons causing extensive engine damage. The Auto Clinic can service your MINI before such a catastrophic event occurs.

ROUGH RUNNING, CHECK ENGINE LIGHT N14 TURBOCHARGED COOPER S MODELS

One common problem with these engines is a “carbon sludge buildup” on the intake valves. Restricting airflow into the cylinders causing a rough running and misfiring of the affected cylinders. The proper fix is to remove the intake manifold and remove the buildup without damaging the valves. The Auto Clinic has the tools to quickly perform this repair important repair.
