Known 30DDTX Failure Modes
Timing chain wear
The straight-six shares the Ingenium chain-wear tendency; a cold-start rattle is the warning sign.
Read the Ingenium guide →Turbo & EGR faults
Restricted oil feeds and EGR problems show as smoke, limp mode or coolant loss.
Book diagnostics →Mild-hybrid system faults
Belt-starter-generator issues can present as engine faults — worth diagnosing properly before assuming the worst.

30DDTX Questions
How much does a replacement 30DDTX engine cost, fitted?
Fitted at our workshop, a low-mileage used 30DDTX typically runs £1,000–£2,500, a reconditioned unit £2,500–£5,000, and a full rebuild of your own engine £2,000–£5,000. The exact figure depends on the variant and what the strip-down reveals. All our prices include VAT (GB 502 3788 04). Enter your reg above for a fixed written quote.
Do you supply the 30DDTX on its own?
No. Every engine we supply is fitted by us, at our own workshop in Grays, Essex. That is deliberate: one party is then responsible for both the engine and the fitting, which is what makes the warranty worth having. If you cannot get to us, we can collect your vehicle and deliver it back.
What warranty comes with a 30DDTX?
12 months or 12,000 miles, whichever comes first — parts and labour, in writing. Servicing can be done by us or by any established professional garage; you are not required to come back to us.
What is a D300 or D350 engine?
Those are output designations for the 30DDTX straight-six diesel. Underneath they're the same engine family — give us your reg and we'll confirm the exact unit.
Is the straight-six better than the old TDV6?
It's a newer design without the V6's crankshaft reputation, but it does share the Ingenium chain-wear issue. Our rebuilds address it with a new chain kit.
What a Fitted 30DDTX Includes
Every 30DDTX we supply is fitted by us at our Grays, Essex workshop — never sold loose. Your price covers the whole job:
- The engine — reconditioned, tested low-mileage used, or your own unit rebuilt, matched to your exact variant
- Removal & fitting — the old engine out, the replacement in, by JLR specialists
- Fluids, filters & adaptation — the parts and coding the job actually needs, not billed as extras
- A documented road test — before the car comes back to you
- 12 months / 12,000 miles, parts & labour — one warranty covering the engine and the workmanship
Turnaround depends on the engine — see the lead times in the options above. VAT is included in every price.
Not local to Essex? It makes no difference to the engine or the warranty. We collect your vehicle, fit the 30DDTX here, and return it — wherever you are in the UK. Here's how nationwide collection & delivery works.
