FAQs—Audi A4 Allroad
I parked my Audi A4 Allroad overnight, and the next morning, I found out that my car was dipped on one side. I've never experienced this since I bought my car five years ago. What should I do?
This is a common issue with the air suspension of the Allroad. Sometimes, this happens or the entire front will be all the way down while the back is still up. This is due to a leaking air bag. What you need to do is to prepare a spray bottle and fill it with soapy water. Lift your car as high as you can, and spray the solution onto the air bag to expose where the leak is coming from. If you see a small piercing, bring your vehicle to the repair shop and have your air bags repaired. It is not that expensive, and you should do it immediately. If you ignore this issue, the compressor will burn out from trying to keep the ride height of your vehicle steady. However, if your vehicle won't raise or lower, then there might be a problem with your valve block. It is under the rear of your car that directs the air flow. Replace it when necessary.
I noticed that my Audi A4 Allroad has been leaking oil so badly. I've seen puddles underneath my car almost every day. I inspected my vehicle, and I found out that there are leaks in my valve covers, rear cam plugs, cam adjuster seals, and turbo return lines o-rings under my car. I wonder what's wrong with my vehicle's components. What should I do?
If you have a 2.7T engine, then you are unlucky. This is considered to be the most maintenance-hungry engine by critics. This kind of engine usually leaks oil from any component. The remedy for this is to change the timing belt and water pump. It might cost you a lot of money, but you don't have a choice. If you leave it that way, you will risk breaking the timing belt and bending the valves. You also need to replace the thermostat and the serpentine belt when you reach your 80,000-mile mark. Your CV boots might also need replacement, as it will most likely be cracked and spilling grease on the inside of your front wheels. This could result in a blown out turbo, which would reveal itself through strange noises at your 120,000 miles.
The engine of my vehicle is 4.2L. I've noticed a puddle under my hood, but I don't know where the leak is coming from. Where should I check?
Having a 4.2L is engine is better than having a 2.7T. The former doesn't leak as much as the latter and the usual cause is a failed valve cover gasket or cam adjuster seal. It is also important that you replace the water pump, thermostat, and serpentine belt when you reach 80,000 miles. You don't need a timing belt service because your vehicle uses the chain-driven 4.2L. Just make sure that the CV boots are also in good condition.
