The AOS has caused numerous issues on Porsche engines. As the membrane in the AOS fails, oil is sucked into the air intake. Initially this can show up as a check engine light for fuel adaptations and the oil can be deposited on the o2 sensors and cause emission faults.
Of course, once it fails completely and oil is sucked into the intake, the resultant huge clouds of white smoke are fairly obvious. However, replacing the aos sooner, rather than later, is a good precaution. A failing aos is the likely cause of rear main seal failure, as it is in other VAG cars. Crankcase gas is not extracted well enough, pressure builds in the case under acceleration and escapes out of the rear main seal causing seal failure and the resultant oil leak.
A failing aos also causes oil pass into the intake and will cause the engine management to adjust fuel mixtures. The changing mixture can cause over fueling and lead to other more significant problems. Check to see when the last replacement of the AOS was completed on the car you plan to buy. If there is no record, plan to replace it as a precaution. Make sure you spend time checking the operation of the roof to ensure it goes up and down smoothly.
Most of the top issues are usually simple and inexpensive to fix, but can be annoying if you only discover them when you want to drop the top on your first sunny day. Porsche revised the mechanism that operates the top a few times during the life of the Boxster. Older original versions of the mechanism have parts that cannot be serviced.
They need to be replaced with the entire revised system. Worth checking the history on the car to see if any work on the top has been recorded. Importantly, look for signs of leaks from the roof into the cabin.
Look behind the seats in particular. The rear roof drains can get blocked by leaves and debris over time. This results in rainwater dripping into an area of the cabin in which electronic control units are located. It is simple enough to keep the drains clear, but failing to do so can be an expensive and annoying oversight. Check carefully for signs of cracks or degrading of the stitching around this window.
This can be fixed relatively simply by a competent upholstery shop. Corrosion is a rare item on the bodywork of the Porsche Boxster. Vehicles in the Midwest can exhibit some degrading of the lower panels if they have been subjected to road chemicals.
However, most Porsche owners store their cars over the winter to avoid this. The bodywork of the Boxster should be in perfect condition — in many cases the paint will have faded. Make friends with a good detailer who can do some paint restoration for you.
The suspension on the Boxster is very solid. Naturally, over time and mileage wear can occur in plastic or rubber bushings that help to cushion the ride. Listen out for squeaks or clunks over bumps and check for leaks from the suspension struts. Worn suspension components typically exhibit some noise and will show up as uneven tire wear. Check the tires thoroughly for smooth wear patterns and pay attention to the tire DOT date. Low mileage cars in particular have this problem — the tires do not experience wear because of the lack of mileage.
On any Porsche, make sure you get under the car and take a good look at the inner shoulders of the tires — this is the most common place for extreme wear and the most likely to be missed by a walk round the exterior. The manual and automatic transmissions on the Boxster are generally highly reliable.
Both should change gear smoothly and without any hesitation. The auto transmission can be scanned for faults but rarely has issues. Fluid services can be performed on both transmissions and the duration of the time interval is quite high.
Look for previous indications this has been done or understand where the car is in terms of time related fluid changes for the transmission. Typically, problems with the automatic transmission usually spell replacement — not cheap! The answer depends on who is driving the car! Wear on the Boxster clutch should be very noticeable.
Engine revs will increase while the car does not accelerate. This is usually associated with a nasty burning smell. A slipping clutch spells trouble. When the clutch slips it very quickly does damage to the flywheel.
Check the used Boxster you plan to buy for clutch replacement history and plan to have to do the work at some point in the future. The brakes on the Boxster are generally excellent. Brake pad material does degrade over time, so again on low mileage examples check to see when the last brake service was performed.
The brake fluid should be changed every few years regardless of mileage. Again, a competent shop should be able to measure the moisture content in the brake fluid and recommend the next flush interval. If in doubt, flush the fluid.
Look for new pads on old rotors. Both the pads and rotors should always be changed at the same time. Used car centers are famed for just replacing the pads on old rotors and claiming the car has new brakes. There should be a wear lip on the rotor and the size of that lip will determine how much mileage remains.
Worn rotors crack or disintegrate which can be particularly unpleasant when driving! The design of the Boxster has the placement of the coolant radiators and air-conditioning condensers low down in the front bumper. The position and open vent nature of the design leaves them not only susceptible to stone impacts, but also to corrosion due to the buildup of debris and dirt that is stuck close to the side of the radiators.
These front ducts need to be cleaned out regularly or protected by an aftermarket screen. The front bumper has to be removed to reach the radiators and most owners never do it. Take a flash light and look closely to see whether the front air intakes are full of rotting leaves and debris when you inspect the Boxster.
Damaged or corroded coolant radiators and AC condensers cannot be repaired and must be replaced. Check the AC works and look for signs of a dry white powder stain under the bumper cover — this is a telltale sign of a minor coolant leak.
The exhaust on the older Boxster is now starting to show up as an issue. Cracks in the exhaust manifolds are becoming more common. Often the crack is after the collector and in the main pipe ahead of the catalytic converter. Replacement of the header section is required. For the older Boxster, Porsche does not provide the exhaust header parts any more, so aftermarket replacement is the only choice. The same is true for the catalytic converter sections, which over time will need to be replaced to maintain emission standards.
Often the catalytic converters degrade internally and will fall apart. This can lead to a nasty rattle or worse a blocked exhaust — this is to be avoided if at all possible. The older Boxster is an excellent way to enter the Porsche ownership world for easy money.
Ownership allows you access to the PCA regions around the country and can turn you into an enthusiast, without breaking the bank! The Boxster is very pretty and a fun car, so look past the sparkle and do your research.
However, the parts or the replacement of this is not cheap. So if you are going for the cheapest and oldest Boxster on the used car lot, make sure to check for this problem and any solution that is in place. Think coolant hoses, shifter and suspension bushings, brake hoses, and plenty of other trims and parts that tend to wear out after prolonged use.
If the car you are looking at has already done plenty of miles, its best to take it to a good shop for a pre-purchase inspection. Do not take the dealer's word for it…. The Boxster was showcased as a concept in at the Detroit Auto Show before turning into reality in the summer of Porsche was at the brink of disaster at the time, but major sales, the very year it debuted, brought the Porsche back and turned it into the giant it is today.
For Porsche, the Boxster remains a gamechanger. Arun Singh Pundir has been a longtime media crackerjack and worked most of his life in sales and marketing. In , he officially flipped and switched sides to the editorial. He lives with his wife, two rascally sons and is a car and motorcycle nut in his free time. Not that he has too much free time. He currently writes news, features, and listicles for HotCars on anything that has any number or kind of wheels.
He is also penning pop culture, lifestyle and all things rich for TheRichest. Hence the now-affordable used prices. The first generation Boxsters to reach U. Thanks to dual overhead cams, four valves per cylinder, and a dry-sump lubrication system, the engine was able to make horsepower and lb-ft of torque, with a redline of rpm. Sending power to the rear wheels is a five-speed manual transmission or an optional five-speed Tiptronic automatic. The sprint happens in 6.
The car received a significant update in for the model year, with a bigger base engine, tuned intake runners, and a more powerful S model. Following customer feedback, the base 2. The S model got a 3. It has a higher rpm redline, and was able to sprint to 60 mph in 5. Output from the base 2.
The most powerful first-gen Boxster produced, it made horsepower from its 3. Other upgrades include a short-throw shifter, a bespoke exhaust, a millimeter lower suspension, and a five-millimeter wider track. All 50th Anniversary cars were painted in GT Silver Metallic, with a cocoa brown leather interior and brown soft top. Only examples—reflecting the year of the Spyder's debut—were built, and only were sold in America. The best for you depends heavily on how much you want to spend.
