Problems fixed: Kia, Land Rover and Peugeot

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

The Problem

We have a 2012 Kia Sportage in the workshop that has a non start issue. The vehicle was running when it arrived but now it will not start. We have carried out some basic engine and electrical checks but can’t find the cause. There are several immobiliser trouble codes stored in the fault memory that may or may not be related to this fault.

The fix

This problem affects Sportage models produced 2010-2016. The cause of the non start fault is most likely due to a poor connection between the immobiliser control module and the wiring harness multi-plug. Disconnect the battery before carrying out any repair work on the vehicle wiring. Cut the immobiliser control module wires approximately 120mm from the wiring harness multi-plug and strip back the wiring insulation. Disconnect the wiring harness multi-plug from the immobiliser control module and discard. Using the wiring harness multi-plug repair kit, available from Kia parts department, fit a modified wiring harness multi-plug. Connect the new wiring harness multi-plug to the immobiliser control module. Ensure the wiring harness multi-plug is fully engaged and latched to the immobilizer control module. Erase any stored trouble codes and start the engine to confirm the fault has been rectified.

The problem

We have previously replaced the transmission oil cooler on a customer's 2013 Range Rover Evoque due to a transmission fluid leak from the left-hand front of the vehicle. The vehicle was OK for a while, but has now returned to the workshop with the same fault. Are you aware of any reasons why this component would fail so quickly, before we replace the transmission oil cooler again?

The fix

There is one repair we know about that affects all Range Rover Evoque models with six-speed automatic transmissions, produced 2011-2019. The fault is likely due to the transmission oil cooler chafed through on the bonnet release cable. To prevent premature component failure again, remove and discard the existing bonnet release cable retaining clip. Fit a new bonnet release cable retaining clip, available from Land Rover parts department. Ensure the bonnet release cable is correctly fitted to the new retaining clip. Fit a new transmission oil cooler and ensure the transmission fluid level is correct before carrying out a road test on the vehicle.

The problem

We are having difficulty diagnosing a crackling noise from the radio speakers when a mobile telephone is connected to the USB socket on a 2014 Peugeot 108. There are no trouble codes stored and we have visually checked the wires to the audio unit but have not found the cause of the fault. We are hesitant to replace any components in case a software update will fix the fault.

The Fix

We have come across this fault before and it affects all 108 models with a USB socket up to 10th May 2017. The cause is likely to be due to an internal fault with the audio unit. Remove the audio unit. Locate the identification label on the audio unit and check the version code. If the version code is not N, replace the audio unit with a modified version. This should rectify the fault.
