Level 2 and Level 3 major services include all the items on the level 1 major service. But should include the additional items within the following tables to complete servicing based on the recommendations of Porsche.

Normally Porsche main dealers charge you for a major service, and then charge extra for these items. Some independent specialists include them within their 24k, 48k etc services, but its worth checking, there are no hard and fast rules in what is included as Porsche recommend some of the items we have included here on the basis of time, not on mileages. Check what the garage will include and if anything is missing ask for the missing items as additional paid for jobs.

The level 2 additional items, due at 48k miles and 120k miles are as follows.

Additional items for Level 2 major service (AKA 48k - 120k)
Spark plugs
Replacement on all Boxster models
Pollyrib drive belt

The additional items required in the level 3 service, due at 96k miles and 192k miles are as follows.

Additional items for Level 3 major service (AKA 96k - 192k)

In addition, experience has shown us that the following items are also strongly recommended at ALL major services.

Recommended additions to all the Porsche Boxster major services.
Engine
At major services its generally recommended that a flushing additive in the old oil would benefit ensuring that the oil system was free of any sludge or debris build up. The addition of fuel injector cleaning may also be of benefit.
Exhaust system
Check condition of exhaust system. Particular attention for leaks, damage and corrosion including loose or rusted heat shields (particular problem with Boxsters)
Suspension system
Check for : Cracked or soft suspension bushes, broken coil springs, leaking shock absorbers, excessive movement in balljoints or bushes.
Brake system
Check condition of brake heat/dust shields
Convertable top
Check for smooth opperation, function of microswitches and clear flowing water drain holes.
Cooling system
Check for condensation above coolant cap or other signs of leaking from cap. Also check revision of cooling cap design from part number. Also check opperation of cooling fans.
Diagnostic system
Check opperation of MAF sensor with computerised diagnostic equipment.
Air conditioning Service
It is strongly recommended that you have your air conditioning system serviced every 2 years (or on every major service). The air conditioning system service includes removal of all gasses and oil, flushing of the air conditioning system, vacuum testing the system over an hour, refilling the system with gasses and oil. This proceedure could avoid the AC system suffering a failure such as:- Compressor contamination build up causing failure, Corrosion of the AC components including the condensors due to water build up within the system, failure of the system due to degraded oil. It will also spot any leaks early on and allow steps to be made to rectify a problem before it becomes an expensive one.
Emissions
Check exhaust gas emissions such as CO %, Hydrocarbon parts per million for correct opperation of engine management and catalytic converters.
These items are listed on the basis of experience of Boxster problems and how early diagnosis of problems can save long term costs and avoid breakdowns or reliability issues.
