Problems fixed: Range Rover, Mazda and SEAT

Leading technical supplier Autodata helps you fix three common problems found in passenger cars

The problem

A customer has a 2015 Range Rover Evoque and they are complaining of poor gear shifting and an abnormal noise from the transmission. During inspection of the vehicle we noticed the transmission oil level is low which seems to be due to a large oil leak. So far we have been unable to find the source of the oil leak in the workshop.

The fix

This issue affects Range Rover Evoque models with transmission code 9HP48, 2014 onwards. The oil leak is due to poor manufacture of the transmission oil gallery plate gasket. Remove and discard the transmission oil gallery plate gasket and retaining bolts. Thoroughly clean all mating surfaces. Fit a modified transmission oil gallery plate gasket, available from Land Rover parts department. Refit transmission oil gallery plate using new retaining bolts and tighten retaining bolts to the correct torque of 10 Nm. Observe the correct transmission oil gallery plate retaining bolt tightening sequence, top up the transmission oil as required. Carry out a road test to confirm the faults have been eliminated.

The problem

A 2015 Mazda MX-5 has a fault with the air-conditioning system not blowing cold air. We replaced a seal on the AC high-pressure pipe where it connects to the AC compressor as it appeared to be leaking refrigerant. Now the vehicle has come back to the workshop with the same fault after only a few months.

The fix

The problem affects MX-5 models within the year ranges 14/05/2015 – 19/06/2018. Check the AC high-pressure pipe where it connects to the AC compressor. On closer inspection you will find a hairline crack in the AC high-pressure pipe. The damage to the AC high-pressure pipe is caused by engine movement. Fit a modified AC high-pressure pipe, available from Mazda parts department. Recharge the AC system with the correct quantity of refrigerant and this should rectify the fault.

The problem

A client has brought in a SEAT Ateca produced in 2019 that has a rattling noise from the front door when driving over bumpy roads. The noise stops when light pressure is applied to the door handle – the handle itself seems well fitted with no excess play and there aren’t any obvious loose components in the door.

The fix

SEAT has flagged this as a possible issue for all Ateca models up to VIN 6570059. The issue is excessive free play in the interior door handle release cable; when driving over a rough surface the cable vibrates and rattles against the door frame. To resolve the issue, remove the front inner door panel. Disconnect the front interior door handle release cable from the interior door handle. Twist the inner cable by 180° and refit it to the interior door handle, refit the front inner door handle and the issue should be fixed.
