Verdict & Rating
Rating:
2.5
out of 5
88% confidence - based on 980 UK enquiries and cross-referenced specialist rebuild reports [EM-VERIFIED].
The 306DT and 306PS are high-performance V6s with a known fatal flaw - crankshaft bearing failure can strike without warning from 80,000 miles - budget for a full replacement, not a rebuild.

10 /20
Repair Cost
Midpoint of Reconditioned (Supply Only) range: £6,500–£9,500 → midpoint £8,000 → falls in £7,000–£9,999 bracket → 8/20.
8 /20
Repairability

Replacement Economics
Reconditioned cost (£6,500–£9,500) against conservative lowest host value (XF X250 at £4,000–£12,000, worst-case £4,000) = 163%+ - over threshold.

Best for:
Low-mileage, well-maintained cars with full specialist history.
Avoid if:
No documented oil-change history or any cold-start knock present.
