The wastegate on your turbo is mechanically actuated, there is no solenoid of the defender td5 like on the discovery. Problems with the wastegate would more likely cause a cut out or sudden drop in power.
Spluttering is more likely the injector loom. Pull the red plug from your ECU and look for traces of oil first. |

There is only one red plug. Oil at the plug means a new injector harness. Not a hard job to do. Estimate 45-60mins 1999 Defender TD5 110

Ditto the injector harness,when you have changed it you will need to clean the red plug out a couple of times afterwards to get rid of the residue that finds its way through. A nice easy fix and cheap too. 2005 Td5 90 XS

A new injector harness will cost you about £30 for OEM to £50 for a Genuine one. It often makes sense to get a new rocker gasket on their when your doing the job (£5+).
You need to remover the acoustic cover then the 11 bolts fastening down the cover, disconnect the plugs from the injectors, then the one from the loom. SImply swap and refit. Then as mentioned above keep removing the red plug and clear every week or so until the oil in the main loom ins cleared. |

You don't have to replace the injector harness. Clean the plug fully with electrical contact cleaner. Then Pack connector fully with electrical/silicon grease. This will keep the oil out.

A newer harness (assuming ttuck3r's is now 14 years old) can't hurt, especially if you add these precautions to minimise future issues. There are other mods you can make at the plug ends to properly resolve the problem but these are more complex. There are some detailed threads on the Australian forums. |

I'm sure I read somewhere that Landrover say the loom is a service item and should be replaced every 3 years regardless. Not that I have.

Hello all,
I have the same symptoms (spluttering at high revs - about 60mph in 5th gear, 40mph in 4th, etc.) I checked the red plug at the ECU, but it was spotlessly clean. Could oil in the loom still be the problem? The solution is always to change the loom near the injectors anyway, so I assume the oil is there in my case, and has just not yet made it to the ECU. Or does it have to make it to the red plug to cause the short circuit of the signals? I'll probably change the loom anyway, but would appreciate any comments. Thanks |

Very interesting, i thought it had to make its way to the red plug even though i havent got to replacing mine yet i did clean out the red plug and the splutter persisted for a short while and then stopped, but about 4 days ago i noticed my fuel pump was getting noisy and the next day a got the spluttering again for a short while and now its gone again..
 so im now going to start the process of illimination. |

Sounds more like you have a seized wastegate to me. Check &feature=youtube_gdata_player Andy |

Unplug the mass airflow meter.
It's in between the air box and the turbo. After a few seconds of driving the car will use the ECU preset safe fuelling instead of relying on the MAF. For the first few seconds its gonna drive slow and bad acceleration then it goes like fxxj If the Defender then runs great, buy a new MAF sensor fit and enjoy. Don't run long term with no MAF you will waste fuel and be under and over fuelling depending on the revs ............ To test the waste gate use some mole grips on the actuator rod that goes towards the turbo, push it firmly towards the bulkhead of the car, if it moves in and out waste gate is fine ............. The injector loom is £35 ish, if you can't remember when. It was last done just do it, they last two to three years then start leaking through the loom and can make a mess of the ECU so treat as a service item every two to three years methinks My guess is kangaroo ing or jerky power spluttering, more than likely the MAF Defender TD5 110 DC (Silver) Range Rover Vogue TD6 L322 2006> (Black) |
