AI DiagnosticsExample sessionRough idle. P0351 stored. Replace the coil?
Start with the evidence
P0351 can have causes beyond the coil itself, including wiring and connector faults. Before replacing parts, DENSO recommends a visual check for damage and contamination, using the vehicle manufacturer's instructions as the first reference. 1
Public-web research, not an OEM procedure. Technical figures remain provisional.
Would borrowing the tool change the answer?
Illustrative example · replace with your figures
All amounts in A$, excluding GST. Use fully loaded paid labour costs. Allow for maintenance, calibration, insurance and subscriptions in ownership costs.
Both are assumed for this example. No live availability check is made. Capacity must allow for collection and handover.
Borrowing comes out ahead. 12 jobs over 12 months.
Estimated 12-month balance · 12 jobs
Under your assumptions, before fixed overheads and tax. Not a profit forecast.
Buying becomes cheaper than borrowing at 19 jobs within 12 months — above your 12-job scenario. This cost threshold assumes both options are feasible, not that either is profitable.
Demand is an assumption, not a booking forecast. Fewer jobs can change the answer.
Borrowing leaves $110 per job after parts, paid labour, hire, collection time and transport. Buying deducts $2,400 upfront plus annual ownership costs.
The model assumes identical jobs and steady demand. It excludes financing, resale value, fixed overheads, tax, payment timing and displaced existing work. Budget only tests the equipment purchase, not working capital. Referral assumes no income or cost and no guaranteed partner availability.
