Td5 problem

[dan494]

if its any help I had a very similar problem last week, did the fuel filter, usual suspects etc. Turned out to the be the lift pump

If the lift pump is suspect, take the fuel filter off and see if its brimmed - if not the lift pump is knacks or fuel pipes have holes in.

there is no lift pump on a td5

hodgey its a l/r its bout to break down its what ther famuse for

 

Cheers johnny:thumbup: this is my third landy Td5 and the first one to start acting up mate.

The MAF sensor on my td5 dose nothing, my old one broke and I didn’t relies until I got a nanocom, then got a working MAF sensor just to see and it made no difference even though its confirmed as working and my td5 runs very well considering its standard regardless of if the MAFs is working, disconnected or removed lol

 

I have been through this. If you disconnect the maf I think you put a fault code on the ecu. With the maf disconnected the ecu defaults to an average setting which may at time not be good for mpg. Not sure about td5 but alot of engines too many fault codes and they go in to limp home mode. I bought a cheap maf off ebay and it just had a resistor in so dont go that route.

collapsed cat so its not breathing properly? I dont know if you can legally de cat a td5 but it helped my disco loads and bumped up my mpg/bhp

there is an electric pump in the fuel tank if this is u/s it will affect the engine !

how old is your landrover?

 

i thought the earlyer 10p engines suffered from oil in the wiring loom but the later 15p and 19p engines had this fault fixed

 

Unfortunately not, all TD5s may suffer from this. The problem is actually caused by oil seeping through the connector pins and down the inside of the wires in the harness. The 'fix' simply put more/better O rings on the outside of the connector shell where it passes through the camshaft carrier, and stopped the 'other' problem of oil leaking out and down the outside of the block.

 

The simple and permanent fix is, when you replace the injector harness, to fill the connector shell up with oil resistant silicone sealant to plug the inside of the connector completely. This will prevent oil getting into the pins and hence fix the problem.

 

LR will tell you (at least they told me) that to fix the problem on my Disco (which was one of the ones they claimed wouldn't do it anyway!) I needed a new injector harness (£50), main engine harness (£120) and possibly ECU (£lots). In practice you only need to replace the injector harness, modifiy it as above, then clean up the ECU connector periodically until the residual oil stops coming out.

Sounds like the same symtoms ours suffered from last year.... Loss of power eventually developed into smoking and lumpy running Landy.

The cause.... diesel leaking into the block through a hairline crack in the head. Check your oil levels as there were no other obvious signs as to the reason behind the fault.

Landy is now sorted, it was the air mass meter, put a new on and shes great!
