Thread: td5 engine bogging out

anyone thats recomended here in melb to check this thing out.?

cheers mark

Had similar problem, it turned out to be the wastegate was out of adjustment which caused it to over turbo.

I get this some times as well. Or use to. So here my theory,
1: Oil could be building up in the Inter cooler. (Comes from the engine cover breather).
Fix- give it a good hard run up a hill in 3rd to 4th to 110km/h, every so often.
2:Muffler could be collapsing, restricting high gas flow.
Fix- remove, sounds and go's better regardless.
3:Bad fuel.
Fix-try different retailer for awhile. change filter.

The valve itself may be faulty,not expensive to replace and can cause these issues if not working properly.

Trev.

this seems like a common cause of such symptoms - and cheap enough to confirm one way or another - a $50 part and very easy to fit yourself...

i finally worked out the problem with my td5 cutting out at high revs.The wiring loom that runs through the head to the injectors and exits at the front(of the head),picks up oil which then makes its way through the loom to the computer.Ive been told this is the problem and quite common, im dealing with winston and pat at american and british 4wd parts in brooklyn vic.at the moment they are negotiating a quote with the car yard i purchased the car from so hopefully in the next few days i should know more.ill post the outcome.thanks to all for there help regarding this issue

Thanks for posting up the resolution. Always nice to find out what was actually wrong.

Not quite common, VERY common..........If you have a TD5 and have not changed one, you WILL at some point takes about 2 hours max from start to finish.

Just bought my 2001 TD5, 126k's, First drive Iput my foot hard down at about 80 kph & it seemd as if it changed to a very low gear, reved quickly to over 4000 cut out for a second & went again to over 4g's giving a surging effect. I thought it was hitting a rev limit causing this due to changing down to low. Soon learnt to keep my foot slightly off the floor when in a hurry & all seems fine

Mine did this....fault was MAF sensor,replaced,all ok.You could try cleaning it & see if there are any improvements.
