Discovery 3 & 4 TDV6 & TDV8 Non-Start

We are seeing an increasing number of Discovery 3 & 4 models with TDV6 & TDV8 engines where the vehicle has been running without problems then suddenly the car wont start. If after checking there is enough fuel and listening under the vehicle for the fuel pump running, you can then check that the low pressure fuel pump is producing about 5 bar at the schrader valve at the rear of the engine.

You may find that there are error codes mentioning voltage low, DC/DC Converter and even fuel rail pressure. Low Frequency coil and other unusual error codes.

These problems are often caused by failure of the PCM (Power |Train Control Module) and often corruption of the software in the PCM

We are able to fix these problems using either Exchange ECU's or simply by upgrading the software. Sometimes we need to flash the memory in the ECU with the latest software on our Test Bench before we can instal the correct software and configuration data.Typical repair cost is about £350 including UK carriage.
