Engine Diagnostics Service

If you have a late model MGF or a TF (clearly you will not be wanting hydragas pumped if you have a TF), I can offer a basic electronic diagnostic service for your car.

Cars produced after 2000 (most Mk 2 MGFs) and all TFs have a MEMS3 engine management control system.  This has a diagnostic port under the steering wheel, which specific equipment can be attached to.  This can either be done by a handheld reader to look for faults, or a more in-depth analysis can be carried out on a  laptop *(I have just upgraded to Windows 7 and have not checked the laptop still works but still have the handreader).

Why would I need this?

If there is someting wrong with the managment system that controls all aspects of the engine and all sensors etc, then a code is stored in the system to alert the dealer during servicing , or to help diagnose problems.  This is often (but not always) accompanied by illumination of the engine warnign light on the dashboard.  As I said this is not always the case, and errors can be present in your system leading to poor running, or increased fuel consumption, failed emmissions test at MOT etc, with no warning light.

The reader (when used with laptop) can identify the following
  • Engine RPM
  • Calculated Load Value
  • Coolant Temperature
  • Fuel System Status
  • Vehicle Speed
  • Short Term Fuel Trim
  • Long Term Fuel Trim
  • Intake Manifold Pressure
  • Timing Advance
  • Intake Air Temperature
  • Air Flow Rate
  • Absolute Throttle Position
  • Oxygen sensor voltages/associated short term fuel trims
  • Fuel System status
  • Fuel Pressure
  • Many others...
It can also be used to reset the warning light if yours is on.  However, it is recommended only to do this when you have identified what caused it in the first place.

I am sorry, but if your MGF is a Mk1 style (before 2000) then the engine managment unit is different and I cannot read the data.

This will be free of charge to people getting hydragas pumping, but for TF owners, will require a very small charge (can cost around £40  at a dealer!!!)
