|

My 2005 Defender td5 developed a fault and I need some guidance where to look for it.
When started, the engine develops very little power, and I can not keep up with traffic. Max speed about 50 mph. After a time, anything between 5 and 30 minutes, power comes back and all is well until the engine is switched off.
I've checked the waste gate actuator, suspecting it may not operate properly. But it moves smoothly (so the wastegate doesn't appear to be stuck open), the small pressure hose to the inlet air pipe (after the turbo) is clear, and when sucking and blowing into the actuator there are no leaks.
Am I missing something? Is this a kind of limp mode possibly caused by something else?
Jim

TD5's do get trouble with oil in the ecu wiring harness at the ecu end, have you checked that?

Got a chance today to check it out; it's completely clean.

Sounds like you need to find someone with a fault reader to see if anything is stored or something pops up on it.I know they did get trouble with hoses collapsing but would not of thought that was the problem it sounds ecu related as it goes into limp mode.At least a fault would give you something to chase.
