Driving down the road and noticing your Range Rover has a rattling noise can be the simplest of things – or make you fear the worse!
The most common causes when your Range Rover has a rattling noise are worn timing chain, camshaft phasers, heat shields, an exhaust pipe problem, or, the worse possible, your crankshaft going bad.
Keep reading to explore if your symptoms are the same, the common causes in-depth, and how you can fix them.
What models are affected?
- Land Rover Defender
- Range Rover Discovery
- Range Rover Evoque
- Range Rover Sport
- Range Rover Velar
- Range Rover Vogue
Signs and symptoms
When it comes to diagnosing range rover rattling noise, you don’t need a magnifying glass or a degree in automotive engineering.
Here are the telltale signs that should raise your suspicions:
- A persistent rattling sound coming from the engine compartment
- The rattling noise intensifies during acceleration
- A rattling noise appears when idling or at low RPMs
List of possible OBD codes
To put you on the right track when troubleshooting range rover rattling noise, keep an eye out for the following OBD codes:
- P0016: Crankshaft Position – Camshaft Position Correlation Bank 1 Sensor A
- P0017: Crankshaft Position – Camshaft Position Correlation Bank 1 Sensor B
- P0018: Crankshaft Position – Camshaft Position Correlation Bank 2 Sensor A
- P0019: Crankshaft Position – Camshaft Position Correlation Bank 2 Sensor B
Now let’s dive into the depths of this rattling conundrum. Here are some common culprits behind that vexing range rover rattling noise:
- Worn Timing Chain Tensioners: These small but mighty components can wear out, causing the timing chain to become loose and resulting in a rattling noise.
- Faulty Camshaft Phasers: If the camshaft Phasers fail, they can create rattling sounds due to improper synchronization.
- Loose Heat Shields: Over time, heat shields can come loose and produce an irritating rattling noise, especially during acceleration.
- Loose or Damaged Exhaust Components: Exhaust pipes, mufflers, and catalytic converters under your Range Rover may suffer damage or become loose, leading to rattling noises.
Can it be fixed without a mechanic?
Ah, the eternal question. While we mechanics love seeing you struggle, I’ll throw you a bone this time.
Depending on the cause of the rattling noise, there are a few things you can try before waving the white flag and calling for professional assistance.
However, be prepared to get your hands dirty!

To tackle this challenge, you’ll need the following parts:
- Timing Chain Tensioner Kit
- Camshaft Phaser(s)
- Heat Shield(s)
- Exhaust Gaskets
Tools you’ll need to fix it
Here’s a handy list of tools to have at your disposal:
- Socket set
- Torque wrench
- Screwdriver set
- Pry bar
- Rubber mallet
- Jack stands
- And a healthy dose of patience!
How to fix it
Now that you’re armed with the right parts and tools, it’s time to silence that rattling noise once and for all.
Follow these step-by-step instructions:
- Identify the source of the rattling noise by carefully inspecting the engine compartment, exhaust system, and heat shields.
- If the timing chain tensioners are to blame, safely lift your Range Rover and remove the engine cover.
- Disconnect the battery, remove any obstructions, and unbolt the timing chain cover.
- Replace the worn timing chain tensioners with the new ones and ensure proper alignment.
- In the case of faulty camshaft phasers, remove them by carefully following the manufacturer’s instructions.
- Install the new camshaft phasers, paying close attention to correct positioning and alignment.
- For loose heat shields, tighten or replace the damaged ones using the appropriate tools.
- If the rattling noise persists, inspect the exhaust system for any loose or damaged components.
- Replace any faulty exhaust gaskets and secure the exhaust pipes, mufflers, and catalytic converters as needed.
- Once your repairs are complete, reassemble all parts, lower your Range Rover, and reconnect the battery.
Potential alternative causes
If you’ve followed the steps above and the rattling noise still haunts your Range Rover, fear not.
There may be some alternative causes worth investigating, such as:
- Loose or damaged motor mounts
- Failing water pump
- Faulty belt tensioner
- Transmission-related issues
How can I tell if the rattling noise is coming from the engine or the exhaust?
Distinguishing between engine and exhaust rattling can be tricky. Listen carefully and consider factors like noise location, RPM changes, and exhaust smoke to determine the source.
