Common Issues with the Audi S8
The Audi S8 is a lightweight car from Audi that features a lightweight, aluminum-based body. It is marketed as being the car that fulfills the role of top-of-the-line for both the A8 line and the S line. It incorporates a downsized and upgraded V* engine for maximum performance and economy. While it looks as if everything you're looking for in a car is there, there are still some problems inherent with this model. Here's a look-see at some of the more common complaints with the S8.
There has been a spectacular problem involving the thermostat of the S8. So spectacular, in fact, that even though it's minor, it has affected a lot of models from the 2001 model up to the 2010 model. This is due to the thermostat being stuck. This stuck thermostat then compounds the problem, leading to the Check Engine Light lighting up. An even worse problem translates into overheat of the engine.
An oil leak is one of the problems that is most common with the S8. It may start out as a harmless leak but with time, the problem may worsen to include leakage in the transmission fluid or something far worse. This problem is commonly experienced with Audi S8 models ranging from the 2001 to the 2010 model. Most commonly, the issue starts off with problems involving the propeller shaft seal on the rear-side transmission. New Audi S8 parts are recommended in solving this problem.
CV Boots and Joints
There have also been reported cases of S8s with problems about their CV boots and joints. Torn CV boots fails to keep oil within a joint, which is a problem. A well-lubricated CV joint is needed for a half shaft to work properly, and without it, there is an annoying (and rather bad sounding) click accompanying each turn of the vehicle. It is for this reason that a replacement may be necessary to keep these CV boots and joints in working condition.
Other minor issues
There have been other cases wherein the S8 failed to give the best satisfaction to the buyer. In these cases, there are some problems reported with the clogged drains. A clogged drain can seriously affect an S8's overall performance and can seriously damage S8 accessories as well. Parts that may be affected include the vehicle's interior, brake booster, or electrical components. Damage to these parts may result in a real loss of money, not to mention a loss of life.
Flooding in these parts may be attributed to clogging caused to the grills at the bottom of the windshield. Sources for these problems may come from outside factors such as debris falling into the grills, or leaves, which are more common at home.
What is technically interesting about the Audi S8? And was the Audi S8 the car used in the film "Ronin?"
The Audi S8 is Audi's luxury car flagship and only the third model for the North American market to proudly sport an "S" badge. Vehicles bearing the "S" and "RS" nameplates were made to compete directly against performance models from divisions such as BMW's M and Mercedes Benz's AMG. The S8's aluminum space frame chassis gave the vehicle its relatively light curb weight while its all-wheel-drive system made it incredibly agile for a luxury sedan.
And, yes, indeed! The Audi S8 gained popularity after being featured as a getaway vehicle in the movie "Ronin"(starring Robert De Niro). The vehicle's dramatized speed, toughness, and durability on screen generated many positive impressions for both the vehicle and the brand.
I've gone through all the manuals for this car, but I can't start my radio today. The screen does work, I see everything on this screen, I know the code but none of the buttons work. What did I do wrong?
Note that this is not a touchscreen model. Try initiating a hard restart for the unit by removing the battery and cable, and wait for approximately five minutes. The unit should start up like it should after this procedure.
The navigation system in my Audi S8 can't seem to be getting a lock on any satellites. Any ideas on what I need to check?
Though the antenna or aerial is the most obvious suspect,the problem could be internal, such as a failed tuner reception chip. These sorts of faults would require the correct dealer software to locate the fault.
The timing belt hydraulic tensioner is leaking intermittently, causing the upper half of the belt loop to loosen. Are there any issues with this OEM part? Also, the vehicle's Tire Pressure Monitoring System is showing an error signal and cannot setup. Is there a way to check the status of the system?
If the belt is fairly new and stretched, it can cause the tensioner to over extend, causing it to leak. You may also want to check the oil pressure because high oil pressure can cause the seals to leak, too.
As for your vehicle's TPM system, the dealer has a scan tool just for the TPM that can check for trouble codes by scrutinizing each sensor. As long as all your tire pressures are good, go ahead and have a mechanic inspect the system.
My Audi S8 has oil in water. No water in sump but runs smoothly on all cylinders. Could the issue be the oil cooler? Also, when the car's air conditioning is in use, the driver's and passenger's footwells are filled up with water. Shouldn't this water be channeled via a hose or small pipe out of the vehicle?
Oil in water could mean a leak in the cylinder head gasket. Oil pressure is much higher than coolant pressure, so oil will more readily push into water passageways. Another explanation could be a leak in the transmission oil cooler pipes. Check that the pipes enter the bottom of the radiator.
As for your air conditioning, the water is probably condensing on an outer pipe then dripping inside the car from some badly insulated gasket. You need to investigate where the water comes from and re-insulate the gasket or clean the drain hose.
