Porsche Service & Repair in Fort Collins, CO
Independent Porsche Service Backed by More Than 40 Years of European Experience
A Porsche is not simply another European vehicle.
A 911, Macan, Cayenne, Boxster, Cayman, 718, and Panamera can all wear the Porsche crest while using completely different:
- Engine architectures
- Transmissions
- AWD systems
- Suspension systems
- Cooling layouts
- Electronic controls
At A&B Import Auto, we’ve serviced European vehicles in Fort Collins since 1982.
Our approach to Porsche service starts with a holistic understanding of the Porsche is actually in front of us.
Why Choose A&B Import Auto for Porsche Service?
European Vehicle Experience Since 1982
We’ve spent more than four decades diagnosing, maintaining, and repairing European vehicles.
That gives us experience with both:
- Older mechanical Porsche systems
- Modern electronically controlled Porsche systems
from early water-cooled sports cars through today’s turbocharged, PDK-equipped, AWD, air-suspension, and hybrid vehicles.
Diagnosis Before Parts
Porsche vehicles have plenty of well-known failure patterns.
Those patterns are useful.
They tell us where to look.
They do not replace testing.
A low-boost code does not automatically mean bad turbochargers.
Oil near the transmission does not automatically mean a rear main seal.
Smoke does not automatically mean bore scoring.
A Macan shudder does not automatically mean the PDK is bad.
A low corner does not automatically mean an air strut has failed.
Our job is to determine:
What failed—and what evidence proves it?
Porsche-Capable Diagnostic Equipment
Modern Porsche diagnosis often requires access to information from systems such as:
- Engine management
- PDK
- Porsche Traction Management
- PASM
- ABS / PSM
- Chassis systems
- Fuel and boost control
- Electrical networks
We combine professional diagnostic equipment with physical testing such as:
- Pressure testing
- Smoke testing
- Electrical testing
- Crankcase-vacuum measurement
- Borescope inspection
- Mechanical inspection
The scan tool tells us what the vehicle noticed.
Testing tells us why it happened.
Quality Porsche Parts
Depending on the repair, we use:
- Genuine Porsche components
- OEM parts
- Carefully selected high-quality aftermarket parts
The objective is not simply to install the cheapest part or the most expensive part.
It’s to use the right component for the application.
Open Seven Days a Week
Porsche problems don’t always happen Monday through Friday.
A&B Import Auto is open seven days a week, with capable diagnostic technicians available throughout the week.
Convenience
Depending on availability, we offer:
- Courtesy loaner vehicles
- Local shuttle service
- Vehicle pickup and delivery
If you’re traveling from farther away for Porsche service, let us know.
We’ve worked with customers from across Northern Colorado and beyond and can often help make the visit easier to manage.
5-Year / 50,000-Mile Warranty
Qualifying repairs are backed by our 5-year / 50,000-mile parts and labor warranty.
We believe the warranty should match the quality of the repair.
Complete Porsche Maintenance, Diagnosis & Repair
We service many Porsche systems, including:
- Scheduled maintenance
- Oil service
- Check-engine diagnosis
- Engine repair
- Cooling-system repair
- Turbocharger and boost diagnosis
- Direct-injection fuel systems
- PDK service
- Manual transmission and clutch
- AWD / Porsche Traction Management
- PASM
- Air suspension
- Brakes
- Suspension
- Electrical systems
- Pre-purchase inspections
But the useful part is not simply that we can work on these systems.
It’s knowing how Porsche changed them from one generation to the next.
Porsche Diagnostics
Modern Porsche vehicles are heavily networked.
A warning light or fault code may involve:
- Engine
- Transmission
- AWD
- Suspension
- Stability control
- Electrical communication
A code is a clue.
It is not automatically the failed part.
Our diagnostic process may include:
- Fault-code analysis
- Live data
- Requested vs. actual values
- Pressure measurements
- Smoke testing
- Electrical testing
- Road testing
- Mechanical inspection
The objective is to understand why the fault occurred, not simply erase it or replace the component named in the description.
Porsche IMS Bearing Service
The IMS bearing is one of the most talked-about Porsche concerns.
It is also one of the most misunderstood.
The classic IMS-bearing concern applies mainly to certain naturally aspirated M96/M97 engines used in older:
- 911 Carrera
- Boxster
- Cayman
applications.
Risk varies by:
- Model year
- Engine
- Bearing design
- Previous repairs
- Replacement-engine history
Turbo and GT engines from the same era use different architecture.
And later engines changed the design substantially.
A good IMS discussion starts with identifying the exact engine.
Porsche Bore Scoring Diagnosis
Bore scoring is another concern that deserves context rather than panic.
It is most strongly associated with certain M96/M97 applications, including some:
- 996 Carrera
- 997.1 Carrera
- 997.1 Carrera S
- 987 Cayman S
- 987 Boxster S
engines.
Possible clues may include:
- Cold-start ticking
- Oil consumption
- Smoke
- Sooty exhaust
- Metallic debris
But none of those symptoms alone proves bore scoring.
Inspection should be based on:
- Engine family
- Symptoms
- Borescope findings
- Oil/filter condition
- Supporting mechanical tests
Risk tells us where to look.
Evidence tells us what is actually there.
Porsche AOS / PCV Problems
The air-oil separator and crankcase-ventilation system regulate pressure inside the engine.
A failure may contribute to:
- Heavy smoke
- Rough idle
- Lean faults
- Oil consumption
- Whistling
- Abnormal crankcase vacuum
These symptoms can overlap with much more serious engine problems.
That’s why smoke does not automatically mean:
internal engine failure.
Depending on the Porsche, crankcase-vacuum measurement can be a useful part of the diagnosis.
Porsche Oil Leak Diagnosis
Porsche engines can leak oil from several places.
Possible sources vary by generation and engine, but may include:
- Cam or valve covers
- Oil pans
- Oil cooler or filter housings
- Rear main seal
- IMS flange on applicable engines
- Turbo oil plumbing
- Other sealing surfaces
Oil moves.
It can run down the engine, across cases, onto underbody panels, and rearward with airflow.
That’s why our rule is:
Find where the oil starts, not just where it ends up.
Rear Main Seal vs. IMS Bearing
These are different components.
The rear main seal prevents oil from escaping around the crankshaft.
The IMS bearing supports the intermediate shaft on applicable engines.
They happen to be located in the same general area on certain older Porsche sports cars.
An RMS leak does not mean the IMS bearing is failing.
And an IMS concern does not automatically mean the rear main seal is leaking.
Porsche Cooling System & Water Pump Repair
Porsche cooling systems vary enormously.
A rear-engine 911 may have:
- Engine in the rear
- Radiators in the front
- Long coolant circuits
A mid-engine Boxster or Cayman has another packaging challenge.
A Macan, Cayenne, or Panamera may use:
- Multiple cooling circuits
- Turbo cooling
- Oil cooling
- Transmission cooling
- Active coolant valves
- Hybrid thermal management
Possible symptoms include:
- Low coolant
- Coolant smell
- Overheating
- Temperature warning
- Heater-performance changes
A coolant warning does not automatically mean a bad water pump.
The question is:
Where is the coolant going, or what is preventing the system from controlling temperature?
Porsche PDK Service & Diagnosis
Porsche Doppelkupplung—PDK—is a dual-clutch transmission.
It is not a conventional automatic.
Depending on the system, a PDK concern may involve:
- Clutches
- Hydraulic control
- Mechatronics
- Sensors
- Fluid
- Adaptation
- Software
- Internal mechanical components
Possible symptoms include:
- Harsh shifts
- Delayed engagement
- Shudder
- Warning messages
- Limp mode
A PDK fault does not automatically mean the transmission needs replacement.
The useful question is:
Is the problem electronic, hydraulic, clutch-related, software-related, or mechanical?
Porsche AWD & Porsche Traction Management
Porsche Traction Management—PTM—appears across several Porsche model lines.
But the physical AWD system on:
- 911 Carrera 4
- Macan
- Cayenne
- Panamera
is not identical.
Possible AWD-related symptoms include:
- Binding
- Jerking
- Shudder
- Vibration
- Driveline noise
- AWD warnings
Potential causes can involve:
- Transfer components
- AWD clutch
- Driveshafts
- CV axles
- Differentials
- Sensors
- Tires
Tire circumference and tread matching also matter.
An AWD complaint needs to be isolated before an expensive drivetrain component is condemned.
Porsche PASM & Air Suspension
PASM and air suspension are not the same thing.
PASM
Controls damper force.
Air Suspension
Controls springing and ride height.
Depending on the Porsche, a chassis complaint may involve:
- PASM damper
- Air spring
- Compressor
- Valve block
- Ride-height sensor
- Control arm
- Bushing
- Software
- Electrical control
A low corner does not automatically mean a bad air strut.
And a PASM warning does not automatically mean the shock absorber itself has failed.
Porsche Direct Injection & Fuel-System Diagnosis
Modern Porsche engines use sophisticated direct-injection systems.
Depending on the engine, this may include:
- Low-pressure fuel pump
- High-pressure pump
- Fuel rails
- Pressure sensors
- Direct injectors
A fuel-pressure fault should lead to questions such as:
What pressure did the engine request?
What pressure did it actually receive?
Is the sensor wrong—or is it correctly reporting something wrong?
A low rail-pressure code does not automatically mean a bad high-pressure pump.
Porsche Turbocharger & Boost Diagnosis
Turbocharged Porsche vehicles may develop:
- Low boost
- Overboost
- Reduced power
- Limp mode
- Hissing
- Inconsistent acceleration
Possible causes can involve:
- Turbocharger
- Wastegate
- Actuator
- Charge-air leak
- Intercooler
- Boost sensor
- Fuel or ignition problem under load
A low-boost code tells us the engine did not receive the pressure it expected.
It does not automatically mean:
replace the turbocharger.
We compare:
requested boost vs. actual boost
and determine what prevented the two from matching.
Porsche 911 Service & Repair
The Porsche 911 spans several very different generations.
996
May involve:
- M96
- IMS
- Bore scoring
- AOS
- Manual or Tiptronic
997
Spans both M96/M97-era and later direct-injected MA1 architecture.
991
Introduces even more advanced PDK, chassis electronics, and turbocharged Carrera engines on later models.
992
Adds:
- Advanced turbocharging
- 8-speed PDK
- Sophisticated chassis systems
- Hybrid-assisted powertrains on newer variants
The badge says 911.
The generation tells us where to look.
Porsche Macan Service & Repair
The Macan combines:
- Turbocharged engines
- PDK
- PTM AWD
- Performance suspension
- Daily-driver utility
Possible areas of concern can include:
- Transfer-case shudder
- PDK
- Turbo / boost
- Cooling
- Oil leaks
- PASM
- Air suspension
- Brakes
- Tires
A Macan shudder can come from several systems.
We isolate the vibration before deciding which drivetrain component is responsible.
Porsche Cayenne Service & Repair
The Cayenne combines Porsche engineering with the demands of a heavy luxury SUV.
Depending on generation, it may use:
- V6
- V8
- Turbo
- E-Hybrid
- Tiptronic
- PTM
- PASM
- Air suspension
- Advanced chassis systems
Cooling, braking, drivetrain, and suspension loads can be substantial—especially during:
- Towing
- Mountain driving
- Winter use
The Cayenne should be diagnosed as both:
a Porsche and a high-load luxury SUV.
Porsche Boxster, Cayman & 718 Service
Porsche’s mid-engine sports cars span several engine generations.
Depending on the car, service may involve:
- IMS
- Bore scoring
- AOS
- Cooling
- PDK
- Manual transmission
- Turbocharged flat-four
- Naturally aspirated flat-six
- GT-oriented chassis systems
A 986 Boxster, 987 Cayman S, 981 Cayman, and 718 GTS 4.0 are very different cars mechanically.
Generation matters.
Porsche Panamera Service & Repair
The Panamera combines some of Porsche’s most sophisticated systems in one vehicle.
Depending on model, that may include:
- Turbo V6 or V8
- PDK
- PTM
- Air suspension
- PASM
- Hybrid systems
- Active chassis technology
A hesitation, vibration, or chassis warning can involve several overlapping systems.
The symptom needs to be separated before the repair is chosen.
Porsche Brakes
Depending on model, Porsche braking systems may include:
- Conventional iron rotors
- Large multi-piston calipers
- High-performance brake packages
- PCCB ceramic brakes
Possible service needs include:
- Pads
- Rotors
- Brake fluid
- Wear sensors
- Hydraulic diagnosis
The correct recommendation depends on:
- Brake system
- Driving style
- Condition
- Track use where applicable
Porsche Suspension & Steering
Even the most electronically advanced Porsche still uses conventional mechanical components such as:
- Control arms
- Bushings
- Ball joints
- Wheel bearings
- Tie rods
Possible symptoms include:
- Clunks
- Steering looseness
- Uneven tire wear
- Vibration
An alignment cannot repair loose suspension.
Mechanical condition comes first.
Porsche Electrical Diagnosis
Modern Porsches rely on interconnected control modules.
One problem involving:
- Battery voltage
- Power supply
- Sensor
- Network communication
can create multiple warnings at once.
That means a dashboard full of faults does not necessarily mean:
multiple systems failed independently.
We look for the common cause.
Porsche Battery & Charging Problems
Porsche vehicles—especially sports cars—may spend more time parked than ordinary daily drivers.
Possible battery-related symptoms include:
- Slow crank
- Dead battery
- Multiple warning lights
- Functions temporarily unavailable
We distinguish among:
- Failed battery
- Charging problem
- Parasitic drain
rather than simply replacing batteries repeatedly.
Porsche Pre-Purchase Inspection
A Porsche can be an excellent used-car purchase.
It can also contain expensive systems that deserve inspection before money changes hands.
Depending on generation, a Porsche PPI may include:
- Diagnostic scan
- Service-history review
- Engine leaks
- Cooling system
- IMS history where applicable
- Bore-scoring inspection where appropriate
- AOS/PCV
- PDK or manual transmission
- AWD/PTM
- PASM / air suspension
- Suspension
- Tires
- Brakes
The correct inspection depends on the exact model.
Known Problems Help Us Know Where to Look
Porsche ownership generates a lot of internet discussion.
Some of it is useful.
Some of it turns:
possible failure pattern
into:
automatic diagnosis.
We take a different approach.
If a Porsche model is known for a particular failure, that information helps us build a test plan.
It does not give us permission to skip the test.
Our process is:
Complaint → data → testing → root cause → repair → verification.
