Common Porsche Problems

A collection of Porsche problems frequently seen at our Porsche repair shop in Ann Arbor, MI.

Oil Level High or Low Warning Message

Problem: Oil Level Warning Message

Porsche has issues with the engine oil level sensor reporting incorrect oil levels.

Unfortunately, on some Porsche models, there is no oil level dipstick to confirm the oil level quickly. The oil level is measured electronically, and there is no manual way to verify whether it is low or high or if the sensor is faulty.

Repair: Confirming the engine's oil level requires draining and measuring the oil volume. If the measured amount of engine oil is correct, the vehicle has a wiring problem, or the oil level sensor needs replacement.

Faulty Oil Pressure Monitoring

Problem: False Oil Pressure Warning Message

The oil pressure monitoring fault can appear randomly and often occurs at highway speeds.

Note: It is best not to ignore oil pressure warnings! Low oil pressure can cause severe engine damage. Oil pressure warnings should be investigated immediately. The critical question is whether the warning is a genuine mechanical pressure fault that can do harm or an electrical or sensor problem.

Diagnosis: Scan vehicle computer for specific error codes, measure the volume of oil in the engine, measure engine oil pressure, test for electrical and wiring problems, and check for oil pressure sensor failure.

The oil pressure sensor and sensor wiring are located at the front of the engine and commonly fail electrical testing. This problem can be frustratingly intermittent and the result of prolonged high heat generated by the engine. This is why the problem is commonly experienced during extended highway driving in hot weather and not during city driving.

Another reason a Porsche oil level warning problem is difficult to diagnose is that the problem does not set a specific computer error code that tells the repair technician where the problem occurred. It only sets a failure event warning with no specific failure details. Having a specialized Porsche computer scan tool at our shop allows our Porsche technician to read failure events and correctly diagnose this problem.

Repair: Oil Pressure Warning Messages can range from oil pressure sensor replacement to electrical wiring repair to oil pump replacement.

Timing Case Cover Oil Leaks

Problem: Oil Leak from engine

Porsche Macan V6 suffers from timing case cover seal oil leaks.

Diagnosis: Macan engine oil leaks can originate at any of the many seals and gaskets on the engine, but oil leaks from the timing cover are common. Leaking oil always moves downward towards the oil pan and the rear of the engine. Since the timing cover seal replacement is complex and expensive, it is important to identify the oil leak source correctly. The timing cover seal replacement is not simple and requires extensive Porsche repair knowledge and experience.

Repair: Porsche Macan timing cover seal replacement often requires engine removal.

No Start - Fuel Pump Failure - Random Multiple Misfire

Problem: No Start, Start and stall, Check Engine Light, Random Multiple Misfires

The Porsche Macan direct injection (DFI) engine uses two fuel pumps: an electric-powered low-pressure in-tank fuel pump and a mechanical high-pressure fuel pump driven by the engine.

Diagnosis: Determining which fuel pump has failed requires careful and accurate diagnostics. Our skilled Porsche technicians have the training and experience to diagnose this problem correctly.

A failing fuel pump will cause low fuel pressure, which causes random engine multiple misfires and a loss of power under acceleration. The low fuel pressure condition and misfire will set a check engine light condition on your dashboard and fault codes, which help diagnose the problem. As the problem gets worse, the vehicle will not start.

Repair: Diagnosis; Porsche Macan low-pressure in-tank fuel pump replacement; Porsche Macan high-pressure fuel pump replacement.

Tip: The in-tank fuel pump will last longer if the fuel level is not run low. The fuel acts as a coolant for the pump. Running the fuel level low causes greater wear on the fuel pump. Stop-and-go city driving can worsen this problem when heat from the pavement heats the fuel in the tank.

Clunking Sound on Acceleration - Driveshaft Center Support Bearing Failure

Problem: Clunking or Banging Under the Center of the Car Under Acceleration

Porsche driveshaft center support bearing failure commonly occurs in the Porsche Cayenne and the Porsche Macan. When the center support bearing fails, the driveshaft vibrates, bangs, and thumps under acceleration.

Repair: There are two ways to repair this problem: One is to use a new Porsche-made replacement driveshaft, and the other is to use an aftermarket center support bearing replacement kit.

The Porsche bearing is weak and has not been improved. It will fail again.

We recommend an aftermarket center support bearing replacement kit for a permanent fix. As a bonus, the aftermarket kit does not require removing the driveshaft from the vehicle, saving you money on the repair.

Porsche Cayenne Common Problems

Cayenne / Macan Coolant Thermostat Failure

Problem: The engine takes longer to warm up, the passenger compartment heater output decreases, decreased fuel economy, and the check engine light is eventually triggered.

Cause: Thermostat failure is the most common cause. All Porsche engines use a computer-controlled thermostat that is prone to failure in the open position. This causes a slow engine warm-up and can keep the engine from reaching the correct operating temperature. Usually, a failed engine thermostat will cause a check engine light.

Diagnosis: Computer error code check and analysis. Coolant temperature measurement. Check heater output.

Repair: Thermostat replacement.

Cayenne Coolant Leaks at Front & Rear Engine

Problem: Loss of coolant, Flashing low coolant warning light

The Porsche Cayenne has engine coolant pipe connectors glued into aluminum housings on the engine. When the glue fails, the connection leaks. Two connections will leak: the upper front coolant pipe at the front of the engine and one at the rear. The replacement housings are updated with a threaded insert to connect the rubber hose.

Front Engine Coolant Leak

The coolant leak at the front of the engine is a relatively easy fix. The housing is replaced with the updated part, so the problem will not return.

Rear Engine Coolant Leak

The coolant leak at the rear of the engine is much more complicated to repair. The rear coolant hose housing that distributes the coolant to both cylinder heads is located between the engine and firewall. This housing will need to be replaced and is very difficult to access. This will require removing the engine from the vehicle and is a costly repair.

Diagnosis: A low coolant warning light and a puddle of coolant in the middle of the vehicle, under the engine, either near the front or just behind the front tires, will tell you that you have this problem. A visual inspection will usually confirm this problem.

Porsche Cayenne Coolant Leaks

Problem: Coolant Leaks, Engine Steaming, Engine Overheating

Porsche Cayenne has three common cooling system problems: Coolant Pipe leaks, Water Pump failure leaks, and Coolant Thermostat failures.

Plastic Cooling Tube Failure

Cayenne coolant pipe failure happens suddenly without warning and produces large amounts of steam. The cooling pipes are plastic and can’t withstand the hot environment close to the engine. They degrade and then burst.

Repair: Install an updated parts kit with metal pipes to permanently fix this problem. Porsche Cayenne cooling pipe replacement is an extensive repair that requires removing the intake manifold.

Water Pump Failure

Problem: Porsche Cayenne water pumps are prone to failure. The water pump bearings wear, and the shaft wobbles, causing the shaft seal to fail and a coolant leak. Some Porsche owners detect increased water pump bearing noise.

Water pumps often fail because coolant replacement service is not done. Coolant is a lubricant for the water pump seal. Old, contaminated coolant causes the seal to wear out, and coolant gets into the water pump bearings, causing them to fail.

Repair: Porsche Cayenne water pump replacement. NOTE: A coolant flush and replacement are highly recommended and required for the water pump repair warranty. Also, the accessory drive belts may need to be replaced if the leaking coolant has contaminated them.

Thermostat Failure

Problem: The Porsche Cayenne coolant thermostat is electronically controlled and reports a check engine light error code if it fails. A failed thermostat stuck in the open position will cause the engine to run cold but will not damage the engine in the short term. If the thermostat fails in the closed position, it will cause the engine to overheat, resulting in possible engine damage. Engine overheating can result in cracked cylinder liners, damaged cylinder heads, or total engine failure. If the engine has overheated, the engine will need to be carefully checked for damage before replacing the water pump.

Porsche Cayenne V8 Power Loss & Check Engine Light

Problem: Loss of engine power and Check Engine Light

The Porsche Cayenne V8 engine computer will report Check Engine Light error codes for incorrect valve lift.

Cause: This problem can be caused by two things: a failed Valve Lift Solenoid or a failed Front O2 Oxygen Sensor.

Valve Lift Solenoid Failure

The Valve Lift Solenoid controls oil flow to the camshafts and regulates the valve lift. If the valve lift is inconsistent or incorrect, the engine management computer will record an error code.

Front O2 Oxygen Sensor

The front O2 sensor determines the engine valve lift. Under acceleration, the front O2 sensor sees an increase in exhaust gas flow within a specified range. A malfunctioning front O2 sensor will not react to and adjust the valve lift to the exhaust gas flow change. The engine management system will detect this problem and set a valve lift error code.

Repair: Porsche valve lift solenoid replacement or a Porsche front O2 sensor replacement.

Check Engine Light On With Engine Misfire

Symptoms: Check engine light, Loss of Power, Acceleration Misfire

Diagnosis: Computer error code scan will confirm misfiring, but not a cause for the misfire. Our experienced Porsche technician can provide fast and accurate repair and great value.

Cause: Faulty Ignition Coil, Worn Spark Plugs, Low Cylinder Compression

Faulty Ignition Coil

Problem: Faulty Porsche Cayenne ignition coils cause an engine misfire, set a misfire error code, and turn the check engine light on. A failed ignition coil also causes rough running and shaking, especially at idle, and decreases power.

Ignition coils can also become weak, resulting in a misfire under acceleration. Deleting the check engine light error code temporarily causes the engine to run smoothly at idle, but as soon as the vehicle is driven, the error code is triggered again.

The Porsche Cayenne V8 ignition coils are a common problem. It is strongly recommended that all ignition coils be replaced at the same time.

Repair: Porsche ignition coil replacement.

Worn Spark Plugs

Problem: Engine misfire caused by bad spark plugs.

Worn spark plugs typically produce a loss of power, eventually set misfire error codes, and trigger a check engine light.

The Porsche factory spark plug replacement interval can be too long for some conditions and vehicle use behavior.

Diagnosis: To determine whether the problem is a bad spark plug or a bad ignition coil, swap the ignition coil from the misfiring cylinder with a coil from a known-good cylinder. If the misfire remains on the original cylinder, the spark plug is likely the problem.

Repair: Porsche Cayenne spark plug replacement.

Low Cylinder Pressure

Problem: Engine misfire caused by Porsche low engine cylinder compression pressure.

Mechanical problems in an engine can cause a misfire. The problem can be a worn-out engine with low cylinder pressure if the vehicle has high mileage, a failed intake valve lifter, or, in some cases, the valve keepers failing, causing the valve to hit the piston and cause serious damage to the engine.

Diagnosis: The first step is to check the spark plug and ignition coil. Next, a cylinder compression test is performed.

Repair: This can vary from a valve lifter replacement to a complete engine overhaul to total engine replacement.

Porsche Boxer / Porsche 911 Problems

986/996 Intermediate Shaft (IMS) Bearing Failure

Problem: M96 IMS bearing failure

1997-2005 Porsche Boxer and Porsche 911 with M96 engines have a known failure of the Intermediate Shaft Bearing. This engine design problem can cause serious engine damage if not repaired before outright bearing failure happens.

Diagnosis: Unfortunately, waiting until the IMS bearing fails will damage the engine, requiring an engine overhaul or complete engine replacement!

Repair: To ensure durability and peace of mind, the IMS-bearing must be replaced with upgraded replacement parts. The upgraded bearing should be replaced every 75,000 miles or six years. Driving style and conditions affect IMS-bearing life.

(see our blog article about Porsche IMS bearing replacement)

911 Vacuum Switchover Valve Failure

Problem: cooling system failure warning or sports exhaust always on.

Cause: Multiple vacuum switchover-valves control functions from coolant flow to sport exhaust flaps. When these valves fail, they cause a vacuum leak in the control system, affecting all the vacuum-controlled functions.

Repair: Diagnosis is needed to confirm the problem and the defective vacuum switchover valve. Note: When one vacuum switchover valve fails, we recommend replacing all switchover valves with updated and improved parts.
