Thread: intermittent power loss

Some of the UK 300tdi's had fly by wire throttles just before the TD5 was introduced, not sure about Australia though. If it has throttle pedal sensor is it OK.
Also might be worth getting a clear bit of pipe and fitting it in-line to your fuel return line and seeing how much air is in the fuel line with the car running, could be drawing in air somewhere.

No fly by wire 300tdi in Australia

What did he do to hotwire the solenoid?
Do it again to be sure, if it drives fine again then start tracing the system back.

The black plug would by my first suspect, they fatigue and get loose.

Not sure exactly what he did there but he showed me a length of wire with an alligator clip. He said, "It ran like a rocket and didn't play up when hotwired." He then reconnected original set up and told me to return the car next week when they're going to replace the radiator filler because it was leaking a little. Not being a land rover mechanic he wondered if the defender had an auto cut out (Murphy switch) if it sensed overheating or any loss of coolant. Since he did this on Monday I've hardly had any issues - some very minor brief loss of power. From reading previous posts I'm wondering if the problem had been the connection to the pump and him changing between hotwiring made a better connection? I'm still not confident the problem's gone for good.
