Gas pump clicking

I have 2013 audi a4 about 55,000 miles. When I got my 45k mile service done at audi I brought up to them that I was having issues pumping my gas at times. For example, sometimes the gas pump would just keep clicking to where I wasn't able to gas my car. When I brought it to audi my car was still under warranty, however they couldn't find the problem bc they were able to gas it fine. I explained to them that it only does it on occasion but enough for me to be concerned. They told me in the future if any serious problems happen due to this then bring to their attention that i broug

Hi There,
This is likely related to your EVAP emissions system and something called a purge valve solenoid. The EVAP system prevents fuel vapors from the fuel tank from escaping into the atmosphere. The EVAP system collects and temporarily stores the fuel vapors in the charcoal canister. The charcoal canister is filled with activated carbon pellets that can absorb the fuel vapors. When the engine is running, the fuel vapors are purged from the canister and burned in the engine. The vent control valve (solenoid) controls the flow of outside air in and out of the charcoal canister. When this is not working properly, you may experience the gas pump shutting off prematurely causing it to take a very long time to fill up your fuel tank. This is due to the excess fuel vapor that is present when the purge solenoid is not working properly by releasing these vapors. The gas pumps at the fuel station have automatic sensors on them (for safety reasons) that shut off automatically when too much fuel vapor is present. I would recommend having an expert from Your Mechanic come to your home to take a look at your car to diagnose your EVAP purge solenoid.

How to Identify and Fix Common car Problems ?

Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint.
Although it has above-average reliability scores, the 2013 Audi A4 is not without its share of problems. These range from four recalls due to faulty airbags, cooling systems, and wiring to lesser issues like carbon buildup in the engine.
If your CV joint is worn down, you`ll hear a clicking noise every time you turn. You can usually tell if your CV joint is worn down by checking the amount of play in the joint. If there is more than 1/4 inch of play, then the CV joint needs to be replaced.
Usually, brakes or tires are to blame. If your car starts to shake at speeds over 50 mph, the shaking may be caused by tires that need to be rebalanced. Another possibility could be your tires may be wearing unevenly due to driving habits, rough patches on your daily commute, or even sticking brake calipers.
Low or Dirty Engine Oil

If your car is making clicking sounds when driving, a likely culprit is low or dirty engine oil. Motor oil lubricates all of the components so that you can drive with ease. If you are running low on engine oil, the metal parts may start to tap and grind over time.

Audis are expected to last an average of 150,000 to 200,000 miles as long as you keep up with regular maintenance. You can expect a properly driven and maintained Audi to last 150,000 to 200,000 miles, or 10 to 13 years.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
Low oil pressure might be the cause of those ticking sounds. When vital engine components don`t get adequate lubrication, it might cause other problems, and the engine starts to make these noises. A broken valve train component, such as lifters or cam followers, can also cause ticking, tapping, or clicking sounds.
One of the most well-known reasons for clicking noise in the engine is related to low oil pressure. It can cause the engine`s moving parts to contact each other without proper lubrication.
If you`re hearing a heater clicking noise in the car or clicking noise coming from deep within your dash, the problem is likely the blend door actuator. The actuators are either not positioned correctly, the gear may be stripped, or the actuator may be broken.

I have a 07 Chrysler Pacifica when it get $20 dollars worth of gas it reads full the whole time the pump clicks n u have to pump i
ANSWER : There may be a fault with the vent system for the fuel tank. When you add gas to the tank, the fumes inside the tank have to be vented to allow it to fill. If the vent system is not functioning properly, it can be difficult to fill. The fumes are vented into a charcoal-filled canister and stored until the engine is running. Once you drive the vehicle, valves and solenoids like the purge valve, are signaled to vent the fumes forward to the engine so they can be burned off in normal driving. Have a certified technician check the evaporative system to determine the exact cause.

Why doesn’t car start after running out of gas girlfriend ran gas out of car now won’t start plenty of gas in tank doesn’t sound l
ANSWER : Fuel pumps rely on liquid gasoline for cooling. Consequently, it is recommended to keep the fuel tank at least 1/4 full to prevent the fuel pump from overheating. If the pump is run to the point of being dry, the seal on the impeller can overheat and get damaged. Even if the pump subsequently runs, as you report your does, it cannot develop enough suction to pick up fuel due to the seal damage. That is possibly what has happened in your case but it should be confirmed prior to replacing the fuel pump. In your circumstance the recommended service is fuel pump replacement but if you request that, the responding certified mechanic will do enough tests to confirm that there is no other possible explanation for the failure. There is a quick and direct way to determine if the problem is lack of fuel. Procure a can of "starter fluid" from any department store. Using the material cautiously (it is highly flammable; keep away from flames or sparks), introduce some of the fluid into the intake of the engine while you engage the starter motor. If the vehicle starts and runs briefly, then you know for sure the problem is fuel starvation of course almost undoubtedly caused by the pump failing. Fuel pump replacement can be accomplished in the field, right at your location, if you desire that service.

Cranks and runs rough have to keep foot in gas to keep running. Has new fuel pump and died while driving after pump was changed
ANSWER : Check fuel pressure. There are only three possible explanations: a fault in fuel supply (plugged filter, injectors, etc.); ignition system problems; and air induction including the idle air control valve, throttle position sensor, mass air flow sensor and vacuum leaks including the PCV and EGR systems. If obvious, and easy to check, possibilities do not reveal the fault, the recommended service to request is a rough running diagnostic and the responding certified mechanic will travel right to your location and get this diagnosed and resolved for you. It is also possible that diagnostic trouble codes have set and the mechanic will attempt to retrieve those using an appropriate scan tool. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.

When refilling gas tank, gas overflows before tank is full.
ANSWER : The most common cause of this type of problem is when the fuel filler neck’s inner tube comes off of the neck itself. You will need to have the filler neck removed to check to see if the inner tube was knocked off from someone trying to get fuel out of tank with a siphon hose and managed to knock the hose off. This causes the tank to not get filled properly and the inner hose can get caught in the fuel sender causing wrong readings.

If you’d like to get this fixed, consider YourMechanic, as a certified technician can help you service your fuel filler neck and ensure that your fuel gauge functions normally. Good luck.

truck stalled while pumping gas
ANSWER : You most likely have a leaking fuel tank vapor control valve causing the hard start after refueling. The purge valve is supposed to seal the fuel vapor from flowing except when the vehicle is in a highway cruise situation. It should not flow any vapors when the vehicle is at idle or the engine is off. You should have the purge valve checked and replaced if leaking. The purge valve is mounted on the engine above the front fuel injector on the drivers side. You can test the valve by disconnecting the vapor line and applying vacuum to outlet side of the valve to see if it leaks down and will not hold vacuum.
