Defender 110 tdci power problems
Good evening gentleman,

After your vastly appreciated help with my 2010 110 knocking from the rear, I return to seek advice on a different predicament. Whilst driving, occasionally there is a terrible dead spot, where the engine will idle, but not Rev. After a few seconds of dipping the clutch, it clears and pulls off with no lack of power at all. It can happen when pulling out of junctions which is terribly embarrassing, as it leaves you stranded in the carriage way for a few alarming seconds, and will then pull off fine. Hot or cold engine, full or nearing empty fuel tank. I'm sure it's something simple, but ignorance is my greatest aquiantance when it comes to diagnosing electrical engine or fuel faults.

Many thanks indeed,

Russell

You could try cleaning the contacts to the accelerator pedal. Remove the connector, spray with contact cleaner, replace & check.

The potentiometer assembly inside the box on the pedal could also be at fault, which would require replacement of the acc pedal unit.

I'd probably also clean the clutch sensor contacts on the clutch master cylinder while at it.

Or....it could be something else.
