Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

At 4 years I'd get the polyrib belt changed for peace of mind.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm having a minor service done on my '02 996 next week at an OPC. It's total mileage is only 15,500 (3,000 since last service) but they say it also requires new spark plugs as it's over 4 years old. But surley if they are normally only changed at 48,000 miles they should be OK :?

If you are worried about invalidating the extended warranty, I believe I am right in saying that a manufacturer (or insurer in the case of extended warranty) can only refuse to pay a claim if they believe owner negligence has contributed to the fault occuring.
I would be very surprised if any failure that is covered under warranty could be caused directly by a defective spark plug anyway, and spark plugs generally only deteriorate through overuse (i.e. too many miles) or corrosion (and if you have corrosion in your cylinder chambers a faulty spark plug is the least of your problems!!!)
Spark plug changes are not part of the service schedule, although they generally are due for a change at the same time as an annual or mileage service.

What does the service schedule in the manual say?
If you us V-power or BP 97 octane they will be clean anyway - and at the correct gap if they are supposed to go 48k miles..
Cost of labour and plugs is??

I'd get them changed, it's a fixed price OPC charge now. If you are handy change them yourself.
At 4 years I'd get the polyrib belt changed for peace of mind.

The fixed charge is £167 but with experience I know that some jobs can have a knock-on to further expense.
I had the plugs changed at around 20,000 miles on my 993, but the final bill nudged £500 because they could not remove one plug and it then it required a new rocker cover etc etc...... and the only improvement to the car's performance was down to carrying a lighter wallet !!!

wow that was a bad service on the 993 Mark.
I can fully understand why you feel like that. Are you going to try a different dealer this time and explain your concerns before the work is done to the Service Manager?
