What kind of noise does a Porsche 997 make?
This article applies to the Porsche 911 997 (2005-2012). There are certain noises that those of us who own a car never want to hear as they are sometimes the first indication that something has failed or is about to fail. They could also mean you’re going to have to fork out some cash.
Why does my Porsche make a ticking noise?
Radiated sound from the engine gets reflected from the ground and out the sides of the car. Maybe you should get underneath if you can and make sure that nothing’s touching the polybelt and that the sound isn’t coming from the ancillaries. Do all obvious checks first, like oil an water levels.
How can I tell if my Porsche 911 has a problem?
An early telltale sign can often be one exhaust tailpipe being more sooty black than the other. The sound of this problem is not a tick like a bad lifter, it’s more a rhythmic knock and usually shows up first on the passenger bank of the flat 6 engines.
Why does my Porsche 911 have a vacuum problem?
Crankcase vacuum exceeds the normal range in the engine under heavy acceleration and sucks in air damaging the rear main seal. This is commonly seen on Audi engines as well.
Where is the positive wire on a Porsche air conditioner?
Friction takes over and the two pieces turn in unison. So, let’s shut off the engine and locate the clutch’s wire. The wires are usually found toward the back side of the pulley close to the body of the compressor. The positive wire should have a connector somewhere it to get it’s power. Carefully disconnect the connector.
Why do I have trouble shooting my Porsche air conditioner?
For R12 systems, if you see a strong stream of small bubbles you are low on refrigerant. With R134a systems or conversions we are not to concerned with refrigerant flow observed at the sight glass because the flow can be cloudy and little if any (with R134a you are more concerned with pressures and temperatures).
What happens when you shut off the a / C in a Porsche?
When the a/c electrical circuit to the clutch is excited with 12 volts and enough current the clutch’s magnet pulls the clutch hub into the pulley. Friction takes over and the two pieces turn in unison. So, let’s shut off the engine and locate the clutch’s wire.
Why does my Porsche clutch not work when hot wired?
Clutch does not work when hot wired. Inspect the wire’s connector for poor contact (corrosion or breaks). Check the negative ground wire from the clutch to the compressor’s body. If no problems are found you’ll need to verify if clutch is getting electrical power.
Why do I hear a hissing noise in my diesel car?
Turbo Diesels don’t have Dump Valves like Petrol. They have recirculating valves that force the unused air back into the system, they do have a waste gate so if the Turbo is being fed more air than needed it will divert through the waste gate. The hissing you can hear is perfectly normal.

Why does my Turbo make a noise when I start the engine?
Potential causes of turbo noise include: • Boost/air/vacuum leak – either on your engine intake, or your intercooler • Compressor wheel damage • Split hoses • Over boosting (potentially caused by a wastegate fault) or poor remap. Thankfully, these problems are rarely terminal, and can be repaired/resolved by a competent turbo specialist.

Why does my car whistle when I Turn on the Turbo?
Doesn’t take a turbo expert to suggest that if the noise doesn’t happen when revved in neutral, it’s probably not the exhaust…. The problem with trying to diagnose a noise is that you need to drive the car to be sure what the problem is/might be.
Why does my Turbo whistle sound like a police siren?
In fact, some people purchase aftermarket ‘turbo whistler’ devices that fit inside the exhaust of a vehicle to mimic the sound of the turbo whistle. A turbo whistle shouldn’t be confused with a police siren or dentist’s drill sound – this is likely to be a sign of something more serious, like compressor wheel damage. What causes turbo whistle?
Why does my Laguna make a whistling noise when accelerating?
A few days ago I noticed that my Laguna 2.2 dCi has developed a whistling noise when accelerating in the Turbo range (1800-3000 RPM or so). Doesn’t seem to have affected power but had the car for 5 years and I haven’t noticed this before. Car is a 53 plate with 112k on the clock.

Can you remove the door panel on a Porsche 996?
For details on removing the door panel, see Pelican Technical Article: Porsche 911 Carrera Door Panel Removal. On the 996, when you have the door panel removed, you can view the regulator. The 997 have an inner panel so you will have to watch the actual window.

Is there a problem with my Porsche 911 Carrera?
This “D-chunk” problem seems ironically to occur mostly in gently driven cars. 911 Carreras that are driven hard at the track or on the street do not tend to see this type of damage. At least with respect to the track cars, one theory is that these cars tend to have their oil changed much more often.
What causes smoke at the start of a Porsche 911?
The smoke at startup can also be caused by a air oil separator (AOS) that is going bad but not completely failed yet. The M96 and M97 engines are famed for cylinder scoring – deep gauges in the cylinder liner, usually associated with a knocking noise and eventually catastrophic engine failure.
Why is the Check Engine light back on on my Porsche 911?
The fault codes will suggest faulty O2 sensors. This results in many folks replacing the front O2 sensors in the hopes of solving the problem, only to discover that within a few hundred miles the check engine light is back on. The problem is actually caused by the MAF failing and by owners blindly believing the reported engine faults.

Why is my Porsche 911 not starting up?
If you don’t see any significant change in the voltage after you start up the car, then your alternator or voltage regulator could be faulty. If the voltage is high at the battery (around 17 volts or higher), then the regulator is most likely faulty and needs to be replaced.
