The 911 is the heart of Porsche, and it's the car we see most often at Autos of Europe. Every generation has its own personality and its own list of things to watch.

We maintain 911s that commute every day, 911s that come out only on sunny weekends and 911s that spend their summers at the track.

Top Reviews From Happy Vehicle Owners

996 and 997 (1999–2012)

996 (1999–2005)

The first water-cooled 911, and now one of the best-value ways into 911 ownership. Carrera models use the M96 engine, so the IMS bearing, rear main seal and bore scoring are the main concerns. Cracked coolant expansion tanks, air-oil separators and clogged front radiators are also common. A well-sorted 996 with the IMS done is a wonderful car, and we help owners get theirs there. The 996 Turbo, GT2 and GT3 use the Mezger engine and don't share the IMS issue. Read more about these issues on our common Porsche repairs page.


997 (2005–2012)

  • 997.1 (2005–2008): The M97 engine still has an IMS bearing. On most of these cars it's the larger, non-serviceable type, so oil-filter inspection and condition monitoring are essential. Bore scoring is the bigger concern on 3.8 liter Carrera S engines.
  • 997.2 (2009–2012): Porsche's direct-injection 9A1 engine eliminated the IMS bearing, and the PDK transmission arrived. These are robust cars. Focus on maintenance, PDK fluid service, carbon buildup and cooling system parts as they age.

991 and 992 (2012–Present)

991 (2012–2019)

  • 991.1 (2012–2016): Naturally aspirated 3.4 and 3.8 liter engines, a longer wheelbase and much more electronics. We see PDK service, water pumps and coolant leaks, plus suspension and electrical diagnostics.
  • 991.2 (2017–2019): Turbocharged 3.0 liter Carrera engines. Add intercooler, boost and charge-air checks to the list, and keep up with spark plug intervals.

992 (2019–Present)

The current 911 is the most technologically advanced yet, with an 8-speed PDK, extensive driver-assistance systems and, on the newest models, hybrid technology. Most 992 work is scheduled maintenance, tires, brakes and electronic diagnostics that need factory-level Porsche diagnostic equipment. You can maintain a 992 with us during its factory warranty without affecting your coverage.


Both generations have proven to be some of the most reliable 911s ever built, so a 991 or 992 that's maintained on schedule should give you years of trouble-free driving. The main things we watch are fluid intervals, tire and brake wear on the more powerful models, and software updates that can fix drivability concerns. If a warning appears, our diagnostics can usually pinpoint it in a single visit.

Not sure which of these your 911 needs? Tell us the year, mileage and how you use the car, and we'll put together a plan that covers what's due now and what's coming next. We give you a written estimate before any work begins, and we'll call you if we find anything unexpected along the way. Our technicians spend their days working on 911s, so even the bigger jobs, like an IMS and clutch package on a 996, are routine work for us.

A 911 Shop That Understands the Track

Autos of Europe is a sponsor of the Porsche Club of America St. Louis Region's HPDE events at World Wide Technology Raceway. Many of our customers drive their 911s on track, and we know what that demands: fresh high-temperature brake fluid, careful pad and rotor checks, alignment settings that suit both street and track, and a thorough inspection after every event.


Track driving also changes your maintenance rhythm. Oil, brake fluid and tires wear faster, and suspension components see loads they never would on the street. We'll build a service plan around your event calendar, and if you're looking for more from your car, ask about our performance modifications.


After every event, bring the car in for a quick look. We'll check pad and rotor life, look for fluid leaks and loose hardware, and make sure the car is ready for the drive home and the next session. Track or street, the goal is the same: a 911 that's safe, sorted and ready to drive.

Porsche 911 Service FAQs

  • Which 911 years have the IMS bearing problem?

    The 996 Carrera (1999–2005) and the 997.1 Carrera (2005–2008), with the M96 and M97 engines. Turbo, GT2 and GT3 models of those years use the Mezger engine and aren't affected. From 2009, the 997.2 and every later 911 has no IMS bearing.
  • How often should I service my 911?

    Most modern 911s are scheduled for an oil service every 10,000 miles or once a year. Older 996 and 997.1 models benefit from oil changes every 5,000 to 7,500 miles. Track cars need brake fluid and inspections more often.
  • Can you service my 992 while it's under warranty?

    Yes. The federal Magnuson-Moss Warranty Act protects your right to have maintenance done at an independent shop. Your warranty stays intact as long as the work follows Porsche's schedule and specifications.
  • Do you prepare 911s for track days?

    Yes. Our track-day prep covers brake fluid, pads and rotors, tires, alignment and a full safety inspection, and we inspect the car again after the event.
