I have a 2006 Sport. Over the last three days I have driven back from Spain towing a light weight caravan covering 1000 miles. approx. The message ENGINE FAULT came up a few time on the dash and the engine power was considerably reduced ....What could be the problem? Andrew Kennedy

Could be various things including EGRs, turbo, turbo actuator, turbo hose, fuel pump/filter...

We need fault codes to get any further.

Was there black smoke? Any other symptoms? Visiting from DISCO3.CO.UK

Thanks for yours!! Would the problem be shown up using a diagnostic tool? Or is it the case of looking for the answer to the problem by elimination? Grateful for your comments!! Andrew Kennedy

Sorry I wasn't able to reply sooner. Yes, fault codes and live data from a diagnostic tool will be able to reveal the issue in many cases, or at least give a pointer in the right direction.  Visiting from DISCO3.CO.UK

Can an intermittent fault be recovered by the diagnostic tool. I ask because I have experienced the occasional fault message accompanied by loss of power, switching off and restarting has resulted in normal service being resumed.  past personal chariots

Yes, fault codes have various different states, so historic faults can still be seen.  Visiting from DISCO3.CO.UK

I have had exactly the same experience. Due I am told because I have not been using the engine to anywhere near is full potential - basically the exhaust fumes have gunged up a few sensors. You need to consult a garage who knows the workings of Land Rovers who would sort the problem out. Andrew Kennedy

I have a 2006 4.2 supercharged. Engine fault light, I have been told likely to be EGR, have also been told no ESG on petrol engines. Definitive answer please and if EGR present where can I get same. Otherwise magnificent chariot, I smile every time I get in and smile even broader when that engine fires up, who needs a radio.  past personal chariots
