Question 1

What is Ingenium Timing Chain Stretch (The "Slap") on the Land Rover Discovery Sport (L550)?

Accepted Answer

The 2.0 diesel engine suffers from premature timing chain wear, often called "timing chain slap" as the chain stretches and hits the guides. This is primarily caused by oil dilution from interrupted DPF regenerations thinning the lubricant.

Question 2

What is Oil Dilution & Early Service Warning on the Land Rover Discovery Sport (L550)?

Accepted Answer

Interrupted DPF regenerations cause diesel to leak into the oil sump. When calculated dilution reaches 6% to 7%, the "Service Required" warning is triggered, often as early as 6,000–8,000 miles regardless of the official 21k-mile interval.

Question 3

What is Panoramic Roof and Boot Water Ingress on the Land Rover Discovery Sport (L550)?

Accepted Answer

Blocked drains and poor sealing can lead to wet carpets and electrical faults.

Question 4

What should I check when buying a used Land Rover Discovery Sport (L550)?

Accepted Answer

Ingenium diesels (2015+) need 7-10k mile oil changes to avoid catastrophic timing chain stretch.

Question 5

What should I check when buying a used Land Rover Discovery Sport (L550)?

Accepted Answer

Listen for a rattle on cold start - if it lasts more than 2 seconds, the chain is likely stretched.

Question 6

What should I check when buying a used Land Rover Discovery Sport (L550)?

Check the boot floor and front carpets for dampness; panoramic roof drains frequently block.

Question 7
