Thread: Low power in a td5 (again)

IMO if you have access to nanocom better save a live data log from a journey and post it here then we'll see, if no fault codes logged and the sensor readings are within accepted limits it means it's a fuel supply issue and then you can blame the FPR, a leaking one can't be a good thing cos it's there to bleed the excess of pressure(above 4 Bar) into the return and if the diaphragm is shot (which in most cases causes the leak) it will let more pressure into the return and the pressure in the rail will drop.

Fyi: Pm has been sent to Steako re this. Awaiting a reply.

small rubber hose on side of metal section on turbo hose that goes to the wastegate controller can sometimes perish and crack which will cause a lack of power... difficult to see and worth a look

I did flush the auto last weekend and it could be the problem as I have only driven the twice before work was done I had no reference point will check the level tomorrow. It's quite a process changing the oil and filter on that thing I tell ya. Thanks for the help

I have 15psi of boost ,, my TD5 Auto runs out of puff at 110kph , > from 10kph to 100kph its fine ,, after 110 has nothing ,,,,,, slug when you need to overtake ,,, really it bloody dangerous

I have EGR removed ,, front pope is a straight tru ,
I wouldnt want to drive it to dawin and back ,,
Its just a town car as only had it 2 months and very dissapointed ,,,, >
My D1 landy was a far better car ,,,,,to much electronics ,,,,,
hope you find the drama with yours ,, i have given my D2 to my wife and brought a Land cruiser ,,,,

Yes i love it !

Try disconnecting the MAF.
If it runs better- new MAF
That's where I would start.
IMO the td5 is a far superior engine to the tdi
And pretty easy to troubleshoot once you become familiar with it.
There is only a few sensors that can give you issues.

Change that leaking FPR.

3500 to 3700 still doing @60 Kph. sounds like 3rd gear no toque converter lock up ,,

I would say to drop 20K`s up a hill my tests would be
In order of PITA and $$$$>

#1 check boost ,,,, put a boost gauge I run 15psi ,,, Now from the waste gate there is a pipe ,, (its pressure ) it goes to a alloy box that box drops the diesel if it spikes the pressure ,,, ( its a over boost device ,) i bypass mine ,,but have a boost gauge so i can see what its running at ,,,,,,,

#2 sorry but would need to be a compression test ,,, A full PITA = Pain In Th Ar$e

#3Fuel pressure test to make sure there is enough pressure to pop the fuel into the cyl`s when they open ,


#4 Injectors stuffed ( any smoke ?) best seen at night with a cars headlights behind you ,,,,, should be a little not bellowing

#5 Blocked exhaust ,,, collapsed muffler ( happens more than you think )
