What This Service Involves
Our workshop handles ignition coil and timing system repairs on both petrol and diesel Jaguar V6 engines. The work covers:
- Petrol AJ‑V6 engines — replacement of ignition coils and spark plugs (requiring intake manifold access), and timing chain replacement with new tensioners and guides.
- Diesel AJD‑V6 engines — timing belt replacement, including tensioner and idler rollers, using manufacturer‑specified locking tools.
- Full post‑repair testing, including on‑road validation, to confirm correct operation.
- We use genuine or OEM‑equivalent parts and follow Jaguar workshop procedures for every repair.

Our Process
Vehicle Arrival & Inspection
We receive your Jaguar, perform a visual check, and confirm the scope of work based on your description.
Component Access
For petrol V6 engines, we lift the intake manifold to access the rear‑bank ignition coils and spark plugs. For diesel engines, we remove front covers and auxiliary components to reach the timing belt.
Removal & Replacement
We replace ignition coils and spark plugs (petrol) or timing belt/chain, tensioners, and guides (both) using the correct locking tools and torque settings.
Reassembly & Testing
Components are refitted, the engine is started, and we run full operational checks – including road testing – to ensure perfect function.
Handover & Warranty
We present the completed work with a detailed invoice, and all repairs come with our 12‑month unlimited‑mileage warranty.

Frequently Asked Questions
Do you repair both petrol and diesel V6 engines?
Yes. We work on the naturally aspirated AJ‑V6 petrol (found in X‑Type, S‑Type, XF) and the AJD‑V6 diesel (found in S‑Type, XF, XJ).
Is the ignition coil replacement a straightforward job?
On the petrol V6, accessing the rear‑bank coils requires lifting the intake manifold, which adds time. We perform this carefully using proper lifting methods and new gaskets where needed.
How long does a timing chain or belt replacement take?
Typically 1–2 days, depending on the engine and any additional components that need replacement. We provide a time estimate when we quote.
Do you use genuine Jaguar parts?
We use genuine or OEM‑equivalent parts. All components are sourced from reputable suppliers and come with their own warranty.
Is there a warranty on the repair work?
All our repairs come with a 12‑month unlimited‑mileage warranty. Full details are available on our warranty page.
