Hello All Did a Leak Off Test On A 2004 Transit 2.0 TDCI Today. Owner Said That Under Hard Acceleration That The Engine Will Cut Out Or Switch To Limp Mode.
Went For A Test Drive And Sure Enough 5th Gear 3000RPM Engine Dies Or Goes Into Limp.
Leak Off Test Showed All Injectors 25Ml After 2 Mins At 3000 RPMs Looks High To Me?????
What Do You Think The Normal Leak Back Is???

When i do a pump proof test will i need to undo the injector wiring ?
if i connect my scope to the FRS at the same time as i do the test i can see if the valve on the pump is holding pressure ? Say on a 30sec screen ?
1050Bar after 5 second crank time is this right ?
And i have a maxidas and a launch i used my x431 on the transit in question.
Sorry mate i haven't done the test yet it's a mates van i dont want to lumber him with a bill for injectors then it does not cure his problem.
Will check desired and actual FRP at time of fault tomorrow
Do ineed to remove the injector wiring when i perform the pump proof test?????
Post the capture, that's too long for my liking, it should hit a high pressure (voltage) in less time than that.
Desired FRP & actual at time of fault ?
Hi mate . FRP at time of fault was 132600kpa thats 1326bar FRP volatge was 1.01v?? but may have missed the max on this . will do a pump proof test autodata says 2v at 3000rpm so when i do the test i will look for 2v or above and holding. dont have a pico yet i have a vantage pro so no screen shots. what controls the imv mate the map / maf/ egr position as the egr value was stuck closed freed off the best i can but still 100% better no smoke whatsoever. the van drives all day sweet as a nut until you put your foot down in 4th 5th gear then it cuts out restarts right away. done the leak off 3000rpm for 2 mins 25ml in each pot.
