2001 defender td5. owned 12 months. in this 12 months this problem probably occurred three times, but of late it has become a regular feature, or maybe i just notice it more now.
symptoms in general are power loss, as if the ecu has gone into a safe mode. no power at all , through all the gears,(as if the turbo is not working)and will max out at about 60 mph. this instance usually occurs when under full foot to the floor acceleration in third. - joining slip roads accelerating up inclines etc...its as if it chokes. in normal operation it runs smooth, starts fine everything is fine, even when in limp mode it still runs very smooth and solid, my thoughts have been fuel starvation,if i pulled over and stopped the engine for 20 seconds and the restarted it again, then it would return back to being healthy. i renewed the fuel filter, the air inlet pipe to the air filter had come loose but this fix made no difference either, i have inspected the wiring harness at the ecu end and its all clean and dry. i dont want to go down the route of taking it to a garage for them to try fleece me with new injectors and airflow meters, i think the solution is there in front of me and simple , the fact its at top end acceleration is making me think fuel, but ive reved it in lower gears and its seemed to come through ok, just prolonged acceleration in third / fourth.
i intend to try check for obvious split pipes but its a young vehicle still so these should be fine. i have had waxyoil done last year. maybe its clogged a crucial breather?
any ideas or home tests advice would be appreciated
a guide on specific breathers or pipes to check more closely too.
any idea of costs for having it hooked upto a diagnostics set or anyone near middlesbrough with a home kit to help find the fault
thanks pjb

there are a couple of landy place near me, but ive heard bad tales of their credibility so i am reluctant to have them go fitting new parts until its fixed, i can do that myself. i just want to eliminate the cheap and easy options first. any checks to tell if its a turbo boost issue. fuel pick up pump was mentioned too, but it was like a gusher when ive inspected it.
