Thread: defender tdi300

Mine lost power the other day,one minute it was good the next no power,two lash caps were missing. Pat

sounds to me like a blocking fuel line or a lift pump failing.

also check / tighten / clean the contact for the fuel cut off solenoid. I've found a loose spade terminal to cause similar issues.

cheers fellas for your responses. since last time on i replaced fuel filter (again), filled it up with straight injector cleaner bled it up and gave it a go. and as a result 1st and 2nd gear accelleration has improved the surging quite a bit. 3rd gear accelleration has also improved. but when accellerating in 4th up to reasonable speed it surges quickly and constantly, with small signs of promise for a few seconds. into 5th on the highway is the same as 4th gear at speed. in saying this, idling along at 60 k's in 4th gear in town surging also noticealbe. run out of ideas apart from getting serious with injectors maybe...........

finally sorted the problem, slight lift pump issue coupled with very sneaky small split in vacum hose. also injector diaphram kit. back up to speed again, cheers for everyones input.

Cheers for the update, good if we ever come across this sort of problem!

A slight thread hijack:
When refitting the pump on our TDI in a helluvah rush (never a good working mode...) I fit the fuel inlet banjo bolt to the fuel outlet, and vice-versa. Couldn't figure out why it would accelerate just fine until it hit about 2000 rpms.... after which it behaved like it hit a brick wall....

i have 300tdi defender and want a few more horses.... have screwed in the more fuel screw with small success. going to upgrade intercooler next. my question is, would a discovery transfer case increase top end speed? and is there anything else i could do for a few more horses on the highway?? cheers all.
