Hi, im new to the site, and would appriciate any help i can get, i have a 110 TD5 (2002), drives great always, until you floor the trottle, once it gets to high revs, starts kangarooing, but once you ease off, drives great again, it drives faultless always until you nail the trottle?? I've changed the fuel filter, oil, oil filter, removed the EGR valve, and its still doing it, i'm now considering a new fuel pump, but there fairly pricey, and i don't want to change un-neccessarly. could this be over boosting?? if so how do i change it? or and ideas would be great. Thanks Barry
 
Electronic rev limiter?

Stopping you from revving the engine ro highly - a lot of fuel injected cars do this.

Just a thought?
 
May be the throttle sensor on the pedal?????
You'd need a diagnostic machine to see overboost errors.
Have you played with the turbo settings?
Just some things I'd look at - but I'm no expert.
 
I have exactly the same problem with mine - td5, 2000.

I have changed the injector loom and the problem is still there. I have been led to believe it's over boosting and could be a stuck actuator on the turbo. I don,t know jack about turbos so can't find the actuator but have been told to put a pair of grips on it and try and turn it to check if its jammed.

Its going in for a service tomorrow so I'll let you know what they say...

Hi Barry,

I have exactly the same problem with my TD5 (2000 plate). I've been driving around the problem for the last few months but have finally given up and booked it into my local, friendly, non-franchise dealer next Monday. I'll let you know how he gets on with it. He thinks it may be the air pressure sensor.

I have tried most of the same things as you (except for the EGR valve). As Matt said, it is also worth checking the loom to the ECU, the plugs should be free of oil at both the tappet cover exit plug and the ECU end. Oil in the loom seems to be a well known fault.

I'd be grateful to hear from anyone that has solved this!

Cheers
Neil
 
OK - mine has come back from the garage. They say there are no mechanical faults with it and think it may be and ecu problem.

Strange this is, it seems to work fine sometimes which makes me think its the turbo playing up?
 
I had this problem in my Defender, but in middle range sometimes. The only thing that served was to disconect negative on batt for an entire night. Next day, all was OK....
 
hmmn,

Mines just come back. Looks like a new turbo for me :-(

It's being caused by an erratic boost pressure (i.e. it looks like the wastegate is sticking). They have tried a new air flow meter but it made no difference.

ho hum...
 
In the hope it helps someone else...

My problem (identical symptoms to the first post) was indeed a stiking wastegate.

My very helpful garage have managed to free off the wastegate without replacing the turbo (phew) although we'll have to see how long it lasts.
 
I fitted a boost guage to my td5 its invaluable witrh any turbo engine costs about £50 and will tell you if you have a poor turbo, sticking waste gate or a leak
