Problems fixed: Peugeot, Tesla and Toyota

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

The Problem

We have a 2015 2.0 diesel Peugeot 308 in the workshop that is suffering with engine overheating and the engine malfunction indicator lamp intermittently illuminated. Trouble code P0495 is stored in the engine control module fault memory and at the last service we replaced the thermostat. We have had the radiator flow tested and pressurised the cooling system to check for leaks, but all seems to be OK.

The Fix

The symptoms you’ve described match a recent vehicle that we know has been fixed. The fault affects all models with diesel engines and the cause is due to insufficient cooling of the engine coolant blower motor control module. Remove the engine coolant blower motor and engine coolant blower motor control module. Drill four 8mm holes positioned in the engine coolant blower motor cowling. Refit the engine coolant blower motor and engine coolant blower motor control module. Erase trouble codes and carry out road test to confirm the fault has been fixed.

The Problem

One of our regular service customers has recently purchased a 2015 Tesla Model S and they’ve noticed the audio unit is not working in DAB mode. We’ve carried out some basic wiring checks and all the fuses are OK. We’re hesitant to replace any components in case a software update will fix the fault.

The Fix

The issue affects all Model S models built between 1st April 2015 and 13th July 2015. While the fault can be corrected by a competent technician, we strongly advise that all personnel working on hybrid/electric vehicles are suitably trained to carry out the necessary operations. When working on high-voltage circuits and components ensure all safety related guidelines are adhered to.

The cause of the problem is most likely due to an incorrect specification aerial signal amplifier fitted. Remove the tailgate right-hand trim panel and the aerial signal amplifier. Inspect the part number on the aerial signal amplifier. If the part number is not 1004798, replace the aerial signal amplifier, available from Tesla’s parts department. This should rectify the issue.

The Problem

We’re struggling to diagnose a fault on a 2014 Toyota RAV4 2.0 petrol. The customer has reported that the engine is difficult to start after leaving the vehicle parked for three hours or more. We have carried out some basic checks on the air and fuel system and checked for any stored trouble codes, none were present.

The Fix

This fault affects several Toyota models with 1ZR-FE/1ZR-FAE/2ZR-FE/2ZR-FAE/2ZR-FXE/3ZR-FE/3ZR-FAE engine codes up to March 2016.

The fault is due to an unsatisfactory design of the injectors. To rectify the fault, inspect the production number, if it’s 0692, replace the injectors, available from Toyota parts department. This should rectify the fault.
