So Why Won’t My an Audi Start?

Before we tackle the list of possible faults and fixes, it’s critical to first get on the same page of the core problem. When you hop in your Audi S2 Sedan B4 and discover “it won’t start!”, there could be several components causing the headaches. Maybe the engine isn’t cranking at all, or possibly it’s turning over partially yet not igniting. Or you might hear clicking when you try to start it, but ultimately nothing happens. All these situations can be a sign of different mechanical issues.

Common Reasons Why Your Audi S2 Sedan B4 Won’t Start

There are many culprits as to why your S2 Sedan B4 won’t start. Typical causes include a dead or weak battery, faulty alternator, starter motor failures, fuel system problems, plus electrical or wiring malfunctions. Every one of these issues can show up differently, requiring specific methods of troubleshooting and fixing to get you driving again pronto. All of which, we’ll delve into.

Symptoms of an Audi S2 Sedan B4 That Won’t Start

Spotting these warning signs will help uncover the main issue. Take for example, when you turn the key or press the start button and you hear it clicking but no ignition, it often signifies a problem with either fuel delivery or ignition issues.

Analysis of The Reasons Why Your Audi S2 Sedan B4 Won’t Start

The initial move in remedying the no-start headache is pinpointing the precise source of the trouble. So let’s examine the most frequent reasons behind the S2 Sedan B4 failing to start when you turn the key.

Car Battery Issues Preventing Your Audi S2 Sedan B4 From Starting

Car wont start battery is good

In the majority of cases, the most typical reason an Audi S2 Sedan B4 won’t start comes down to battery troubles. Specifically, a weak or dead battery prevents the engine from cranking. The car’s battery delivers the required power to start the engine and activate all your vehicle’s electrical components. Signs of a dying battery include sluggish or strained cranking, dim headlights, or a warning light illuminated on the dash. A battery charger can recharge a drained battery if you don’t have the help of another vehicle to jump start it, but do have an electrical socket nearby like at home.  And a portable jump starter lets you charge p the battery without another vehicle, and by the roadside without the need for an electrical socket, so you are never stuck.

Alternator Problems Can Prevent Your Audi S2 Sedan B4 Starting

The Alternator keeps the battery charged by harnessing engine power while driving. A malfunctioning alternator can easily prevent your Audi S2 Sedan B4 from starting since it cannot recharge the battery, depleting it completely so that one day you climb into your wheels and it refuses to start up. Signs of a problematic alternator may include a lit up battery or alternator warning symbol on the dashboard, faint headlights while idling, or a whirring noise from the engine while running.

Starter Motor Failures in an Audi S2 Sedan B4

The starter is crucial for cranking the engine when you turn the key to start your Audi. In the event of starter problems, the engine might not crank, preventing your S2 Sedan B4 from starting. Pay attention to clicking noises when you turn the key or grinding during cranking, which could indicate starter problems.

Fuel System Issues Can Prevent an Audi S2 Sedan B4 From Starting

This isn’t about running out of gas like a silly goose. Instead, it’s issues with the fuel system itself that could leave your S2 Sedan B4 unable to start up. Your Audi S2 Sedan B4 uses gas to mix with air and runs the engine. So problems here like a clogged fuel filter or damaged fuel pump relay may mean the engine is unable to get the fuel it needs to start. Fuel injectors can also get clogged over time, so consider a fuel injector cleaner like Red Line to clean them out and improve starting.

Electrical System or Wiring Problems in an Audi S2 Sedan B4 Can Prevent it From Starting

Ok, well yes that image is a joke, but I want to emphasize modern cars now rely heavily on electronics, increasing what can go wrong. With older cars, the usual suspects include blown fuses, spark issues, damaged ignition switches, or broken sensors. Faulty wiring and electronics like these can all prevent your vehicle from starting. Pay attention to your car only starting sometimes, dashboard alerts, or failure to crank as signs of an underlying electrical problem. Pinpointing and fixing these typically requires a knowledgeable mechanic near you.

Solutions: Let’s Get Your Audi S2 Sedan B4 Starting Again!

If you think you might know what the issue may be, it’s time to figure out the cause of your car’s failure to start, and then the next step is to attempt to mend the problem. Here’s advice for the typical problems we’ve covered thus far:

How to Identify and Fix Battery Issues in an Audi S2 Sedan B4

car not starting but battery is fine

If you suspect a battery issue is to blame for your Audi’s difficulty starting, first inspect the battery terminals Ensure they are clean, secure, and properly connected. If the terminals are in fact corroded, try cleaning them with a sodium bicarbonate(baking soda) and water solution.

Once you have checked the battery terminals, you can check to see if the battery is just out of charge, or worse, it’s old and weak, or dead and needs to be replaced. For this, you can charge the battery in a few different ways:

If the battery charges fully and performs as expected, the issue may be resolved. However, if the battery has aged or lacks capacity, replacing it will be necessary. Otherwise, even sufficiently charging it to start your S2 Sedan B4 may only provide temporary relief before it likely runs out of power again soon. Using a multimeter or OB2 scanner to evaluate the battery’s condition can determine if it’s worth preserving or requires replacement. Suitable replacement batteries for your specific Audi can be found on Amazon here by entering your vehicle details to filter for the right fit and choosing a highly-rated seller.

If charging your S2 Sedan B4’s battery fails to solve ongoing issues like frequent draining and recharging even after installing a new battery, an underlying problem likely causes the excessive drain. Professional diagnostic services would then be needed to inspect and identify the root cause. You can also consult a mechanic online through us or obtain an instant quote from a mobile mechanic.

How to Identify and Fix Alternator Problems in an Audi S2 Sedan B4

Car wont start replace alternator needed

If you think the alternator is the reason your Audi S2 Sedan B4 won’t start, a test can confirm. If you can temporarily get the auto running (you may need a jump start), with the engine on, detach the positive battery terminal. It’s probably the alternator if the motor conks out soon after disconnecting the positive lead. However, be careful this test can be dicey and damage delicate electronics in your wheels, so it’s best to talk to a pro mechanic locally or online first since this test risks damaging the delicate electronic gizmos in your Audi S2 Sedan B4.

If you figure out that the alternator is the problem, it’s a case of having it replaced. I recommend consulting an online or local mechanic as they will advise you on how difficult the repair is for your specific model, and you can work out if you want to try it yourself, or with the advice of an online mechanic

If you do want to try it yourself or take it to a local garage, you can often buy the replacement parts yourself cheaper than at the garage, but you need to know what to get for your model of Audi S2 Sedan B4. You find all the information you need about your specific vehicle by searching online for something like “Audi vin lookup“, which is a purchasable report, that will give the specs for your vehicle and which parts are compatible, and then you can go get the alternator parts you need. However, an easier option is, Amazon probably has the alternator you need online, at a cheaper price, and their site easily shows which ones will go in your specific car model. Check the Amazon alternator page here

How to Identify and Fix Starter Motor Problems in an Audi S2 Sedan B4

If you question if the starter motor is the source of your S2 Sedan B4 refusing to start, listen for a clicking noise when you turn the ignition key. If heard, but the engine does not turn over, the starter motor likely requires replacing. You can take it to a local garage and have them repair it, or repair it yourself with the help and advice from an online mechanic guiding you. 

If you need it, one of the cheapest and easiest places to get a new starter motor, for your exact vehicle model is on the Amazon here.

How to Identify and Solve Fuel System Problems in an Audi S2 Sedan B4

If you think a fuel system malfunction might be causing the no-start, listen closely for the fuel pump hum when you turn the key to “on” before attempting to start the car. The pump should emit a faint humming for a few seconds. If such a noise is not heard, the fuel pump could be defective. Problematic starting, stalling, or lagging acceleration may also stem from a problematic or clogged fuel filter. Both pump and filter issues normally need a skilled mechanic to diagnose and fix them properly, often involving fuel pressure testing and specialized diagnostic equipment. Later in this article, I detail the best ways to get help from a local Audi mechanic near you. 

How to Repair Electrical or Wiring Problems in an Audi S2 Sedan B4

If you suspect it’s an electrical circuitry issue, first check the fuses for the ignition system, and swap out any that have blown. If your S2 Sedan B4 starts after this, it was a successful, inexpensive repair! However, if it still won’t start, even sometimes, the ignition switch itself could be the cause of the issue. Warning lights on the dashboard could also mean a damaged component. These can be intricate issues needing a qualified mechanic to diagnose and properly repair (see below advice on local mechanics).

Preventive Steps

As granpa used to say: “An ounce of prevention is worth a pound of cure”. Here’s how to avoid future issues starting your S2 Sedan B4:

Routine Maintenance of Your Audi S2 Sedan B4

Regular maintenance on car to prevent starting issues

Regular maintenance is key to avoiding issues, including oil changes, battery checks, cleaning terminals, replacing the fuel filter as needed, and having a mechanic inspect the car regularly. If unsure about maintenance for your model, consult a mechanic locally or online for guidance.

Drive Your S2 Sedan B4 Regularly

If your Audi S2 Sedan B4 happens to sit parked in the garage or front yard for too long without being driven, the battery can deplete as it is not being charged up by the engine running, through the alternator. Try your best to use your car regularly to maintain a charged battery. If you remember you have not driven your car in a while, take it for a short spin around town to ensure there is still a charge left.

Note: Letting the battery entirely run out of charge is also bad for its longevity, so try to avoid that.

Pay Attention to Warning Signs

Check Engine Control Light on a Vehicle Dashboard

If you notice any abnormal things like unusual noises, changes in driving and performance, or warning lights lit up on the dashboard, do not ignore them. These are often early signs of an issue that should be addressed ASAP before they escalate into larger problems later on. Consult with a mechanic locally or online about these problems and get advice on if they require attention.

When to Ask an Audi Mechanic Online

If you have limited time available, or you gave fixing the no start yourself an honest effort but with no luck, consider consulting an Audi mechanic online. It delivers quick professional advice from the comfort of your living room, and is far less expensive than a tow and diagnosis at the local garage.
