LAND ROVER DISCOVERY 3 TURBO REPLACEMENT

HOW TO REPLACE THE TURBO ON A LAND ROVER DISCOVERY 3

 

Here are the details of my experiences with the replacement of my 2005 Land Rover Discovery 3 turbo. These would apply equally well to a Discovery 4 or Range Rover Sport.  If you are unfortunate enough to be having turbo problems with your vehicle, I hope that this might make it all a little less stressful and expensive.

If you are handy with a spanner and don’t mind having a go, then I would say that the replacement of the turbo is well within the range of a DIY mechanic like me. 

Before you start, consider that your vehicle will be off the road for at least a week, so be prepared.

It is essential to spend the time to jack up all four wheels off the ground and support the vehicle with suitable blocks and/or axle stands.  Make sure it is safe and secure on level ground and that you have enough space to work from underneath.  Ensure that the battery is disconnected before jacking up.

Symptoms of a Turbo Problem

 

Upon acceleration the car will suddenly drop in power and you will have limited power available, also referred to as “limp mode”.  This can be intermittent . Sometimes this can be reset by switching the engine off and on again.

If you think you have a turbo problem, the first, most economical “fix” you can try is to see if the turbo actuator has become stuck. Here is a link to a video on how to free your turbo actuator.

If the turbo actuator has become faulty, you will need to replace the entire turbo as it would appear that the actuator part is not available separately.

In this video I show you how I changed the turbo on my Land Rover Discovery 3, without the aid of a car ramp, and without the need to remove the car body.

Items Required for the Job

 

Below I list all the items that I have used and recommend, with links to find them for your convenience.  There are also one or two that I would absolutely purchase beforehand should I ever need to do it again, for example the under car creeper in place of the cut down dining chair!!  (Disclaimer – If you purchase through one of my links, I may receive a tiny commission.  Rest assured this won’t cost you a penny more, but will go a small way to help me to maintain and update this site, for which I would be hugely appreciative.)

The Turbo

 

The genuine Land Rover part is priced at over £2,000.  The replacement turbo I used was a Borg Warner part priced at around £800.  I found the most competitive price on Ebay.  I can recommend the Borg Warner.  It is a name I trust and after 4 years I have had no issues with the part.  Remember that the turbo has sensors that are connected to the engine ECU and a poor quality part may, or may not, work correctly. Knowing the amount of work required to replace the unit, I don’t think it’s worth the risk gambling with a cheaper part.

This turbo is suitable for:

  • Discovery 3: All model years 2.7TdV6 Diesel
  • Discovery 4: All model years 2.7 TdV6 Diesel
  • Range Rover Sport: All model years 2.7 TdV6 Diesel
