I need some help locating the horn on my car

I have a mk 2 audi tt and I wanted to install a new horn on it, but I didnt realize that it would be so complicated. I was wondering if someone knew the horn location and exactly how to get to it. I think that I have to remove the front bumper or something like that, but have not been able to find any guide on how to do so.

My car has 70000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Most vehicle horns are located either behind the grille or behind the front bumper. I would recommend driving the vehicle up on ramps to determine if access to the horns is possible from under the bumper.

If not, it is possible that the bumper would need to be removed in order to gain access to the horn. It is also possible that the horn is accessible from under the hood. If you are in doubt about this repair, I would recommend enlisting the assistance of a qualified professional, such as one from YourMechanic, to help you replace the horn on your car.

Most cars on the road today have two horns, with both controlled by a single horn unit located under the hood. Lift and secure the hood, find the horn, typically fastened to the front firewall or behind the vehicle`s grille, and unbolt the unit.
If the horn fails, check whether the fuse is sound (See Checking and replacing fuses ). If it has blown, fit a replacement and check the horn again. If the fuse is sound, or if a replacement fuse blows, there is a fault in the circuit or the horn itself.
Car horns function with electric power; therefore, if a blown-out fuse blocks electric flow, electricity cannot get through, and ultimately the horn will stop working or make a weak sound. Thus, the fuse is the first thing to check when the horn sounds weak. The fuse is on the panel inside the car or under the hood.
Connect one clamp to the terminal on the horn and quickly touch the other end to the positive battery terminal. If the fuse blows, you`ve got a bum horn. If the horn makes a clicking sound, the problem could be a poor ground connection. Clean the horn`s ground connection and try powering the horn again.
The horn relay switches a large current to the horns at a signal from the low-current horn button in the steering wheel. It`s a simple, inexpensive single-pole single-throw (SPST) relay, packaged in a small metal or plastic box with five spade-lug connectors.
Since most horns are operated by a switched 12-volt power feed, adding a second horn, or changing the sound (or just sound level) is normally straightforward, though having basic mechanical skills is necessary to do it yourself.
Blown fuse

The horn works using electric power and, just like any other electrics-dependant part, it has a fuse. If the fuse is blown, you`ll simply need to replace it. Modern car fuses have that fork-like look and if the wire between them is broken, then you`ve found your problem.

Fixing a broken car horn can often be a do-it-yourself project. However, when the damage requires that other parts of the car be removed, such as the driver side airbag, you will need to call in a professional.
It provides more amperage to the horn, near the horn, that`s controlled remotely from the steering wheel horn contact(s) with a very low amperage circuit which only feeds power to the relay pull-in coil.
The horn switch circuit is low amperage, while the relay provides a high amperage circuit.
How do I disconnect my car horn? The easiest way to do this is to pull the horn fuse, usually located in the fuse panel under the steering wheel. Look for a cover on the underside of the dashboard; when you remove it, you should see a grid of small, colorful plastic rectangles with numbers printed on them.
Step 1: Disconnect your car`s battery.

This will shut off the horn, but in turn, it will prevent you from starting your car again, and you will need professional assistance.

The average cost for a Horn Relay Replacement is between $56 and $64. Labor costs are estimated between $31 and $39 while parts are priced between $25 and $25.
You could have something restricting your airflow. Make sure you check your air lines for kinks or leaks. Also, check to make sure your the valve for your horn is free of debris.
No. A relay is used to control a high current circuit (horn) with a low current circuit.
Check the fuse

One of the most common causes of a dead car horn is a blown fuse. The fuse box is located in the engine, the side of the dash or on the driver`s side. If you can`t find it, it`s best to check the owner`s manual. The fix is pretty simple, use a jumper cable and connect it to the fuse and jump power.

The average cost for a Horn Replacement is between $146 and $165. Labor costs are estimated between $71 and $90 while parts are priced between $75 and $75.
If you`re considering upgrading the car horns, this entails having it done by a qualified electrician or installer. This is because it requires a wire run from the battery to power them and then wire into the existing horns system using an electrical relay.
Yes. Dehorning significantly decreases the risk of injury to farm workers, horses, dogs and other cattle. Dehorned animals are far easier to handle and transport, and command higher prices at auction than animals with horns.
A horn is built to last for the life of the car, but there are instances where this is not the case. Just like any other electrical component on a car, there will times when a car horn will need replacing due to corrosion or even bad wiring.
Horns may become broken, causing blood loss and potential for infection. Horned animals may become trapped in fences or vegetation, causing self-injury. Horned animals may become more aggressive than those without horns, especially around feed.
Car horns are usually electric, driven by a flat circular steel diaphragm that has an electromagnet acting on it in one direction and a spring pulling in the opposite direction.
Understanding Car Horn

The sound of a car horn must have a vibration frequency between 1800-3350 Hz.

Car horn switches, or buttons, are typically mounted in the steering wheel. Some steering wheel buttons are mounted off to the side of the steering wheel, but most are located directly in the middle of the wheel. Most horn switches are normally open, which means they only close when the button is pressed.

Where is the horn relay located on my vehicle? If that isn’t the problem what else could be wrong with the horn?
ANSWER : Hello. The horn relay should be located in the fuse panel located under the hood. If you do not have a owner’s manual it may be possible that there is a diagram on the inside of the fuse panel cover. If there is no diagram, I would try and source a quality repair manual or consult a shop for diagrams, or a description the exact location. If the fuse and relays are not the source of the issue, then it may be possible that a fault with the horn itself, the clockspring, or the horn circuit wiring are the cause. If you are unsure, I would recommend having a professional technician, such as one from YourMechanic, come to your location, to diagnose if the horn relay needs to be replaced, or perhaps another repair carried out.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

Got a diagnostic, mech says car need theromostat and all coils and plugs. Car was fine then check engine light 2009 Mini Cooper
ANSWER : Hi – I would do a quick check on the problem codes causing the Check Engine light and other warnings you mention. In general you would have an occasional misfire or hiccup that you should feel as engine vibration as any of the 4 coils start to go weak. Some engine ignition systems are more sensitive to coil compatibility than others, and replacing all of them at once with higher mileage is a good guideline. However, you don’t have all that many miles on your Mini. I would challenge the reason to replace all of them on this occasion. I recommend a thermostat replacement and misfire inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose and/or correct these problems, and give you an accurate assessment of other damage and cost estimate for repairs.

Should I buy this car for $1700
ANSWER : Prior to buying any car, drive the car around and listen for any noises. Then do an inspection on the vehicle to make sure that it is safe to drive. All cars will need maintenance, but if the car was kept up, then the maintenance should be to a minimum.

Car horn problem
ANSWER : Hey there. In addition to being a requirement for motor vehicle inspection in every state, the horn is obviously a huge safety component. By all means, you should try to get this working correctly. It is somewhat unusual for a horn to fail, simply because they are not used often – as you mentioned.

Check the horn fuse first, then for power to the horn relay, and on the output side of the relay. Horns can become water damaged however, so if you can determine from your electrical checking that power is getting to the horn, without an audible response, then you will need to replace it.

If you are still having trouble figuring out the horn, a certified technician from YourMechanic can diagnose the problem and follow up with repairs.
