So Why Won’t My an Audi Start?

Before we tackle the list of possible issues and solutions, it’s vital to first get on the same page of the core problem. When you climb into your Audi TT RS 8S and realize “it won’t start!”, there could be a number of parts causing the troubles. Perhaps 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 sadly no ignition occurs. Each scenario can be a sign of different problems under the hood.

Common Reasons Why Your Audi TT RS 8S Won’t Start

There are a host of reasons why your TT RS 8S won’t turn on. Typical causes include a dead or weak battery, broken alternator, starter motor complications, fuel system problems, plus electrical or wiring malfunctions. Each of these concerns can present differently, needing specific methods of diagnosis and repair to get you driving again ASAP. All of which, we’ll delve into.

Symptoms of an Audi TT RS 8S That Won’t Start

Recognizing these warning signs will guide you toward the main issue. For instance, when you turn the key or press the start button and you hear it clicking but no ignition, it often indicates a fuel or ignition issue.

Analysis of The Reasons Why Your Audi TT RS 8S Won’t Start

The first step in remedying the no-start nuisance is pinpointing the specific source of the issue. So let’s explore the most common causes of the TT RS 8S not starting when you turn the key.

Car Battery Issues Preventing Your Audi TT RS 8S From Starting

Car wont start battery is good

In the majority of cases, the most common reason an Audi TT RS 8S won’t start comes down to issues with the battery. Specifically, a weak or dead battery prevents the engine from cranking. The car’s battery supplies the required power to ignite the engine and activate all your electronics. Symptoms of a failing battery entail sluggish or strained cranking, dim headlights, or a warning light aglow on the dash. A battery charger can recharge a dead 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 TT RS 8S Starting

The Alternator keeps the battery charged by using engine power while driving. A malfunctioning alternator can easily prevent your Audi TT RS 8S from starting since it cannot recharge the battery, draining it completely so that one day you hop in your wheels and it refuses to start up. Symptoms of a malfunctioning alternator can be an illuminated battery or alternator caution light on its dashboard, dull headlights while idling, or a whirring noise from the engine while running.

Starter Motor Failures in an Audi TT RS 8S

car wont start wont turn over

The starter is crucial for turning over the engine when you try and start up your Audi. Should the starter fail, the engine can’t crank, preventing your TT RS 8S from starting. Listen for clicking noises when you turn the key or grinding as you try to start it, which could indicate starter issues.

Fuel System Issues Can Prevent an Audi TT RS 8S From Starting

We’re not talking about running out of gas like a silly goose. Instead, it’s issues with the fuel system itself potentially leaving your TT RS 8S unable to drive. Your car uses gas uses fuel to combine with oxygen and powers the engine. So problems here like a clogged fuel filter or failing fuel pump relay may mean the engine lacking the fuel it requires for ignition. Fuel injectors can also get clogged over time, so try a fuel injector cleaner like Red Line to clean them out and improve starting.

Electrical System or Wiring Problems in an Audi TT RS 8S 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, opening up the number of things that can go wrong. Even in older Audi’s, the usual suspects include blown fuses, spark issues, damaged ignition switches, or broken sensors. Electrical issues and electronics like these can all prevent your Audi TT RS 8S from starting. Pay attention to intermittent starting, warning lights, or failure to crank as hints of an underlying electrical issue. Pinpointing and fixing these typically requires a qualified mechanic near you.

If you think you might know what the issue may be, it’s time to figure out the reason behind your car’s inability to start up, and then the logical next move is to try to repair the problem. Here’s advice for the frequent problems we’ve talked about already:

How to Identify and Fix Battery Issues in an Audi TT RS 8S

car not starting but battery is fine

The first step if a battery issue is suspected for the no start is to check the battery terminals. Make sure they are corrosion-free, secure, and properly connected. Should you find corrosion on the terminals, a baking soda and water solution can help clean them.

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 TT RS 8S 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 swapping out. 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 TT RS 8S’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 TT RS 8S

Car wont start replace alternator needed

If you think the alternator is the reason your vehicle won’t start, a test can confirm. If you can temporarily get the auto running (you may need a jump start), and while it’s running, disconnect the positive terminal of your car’s battery. It’s probably the alternator if the engine dies soon after disconnecting the positive lead. However, be careful this test can be risky and damage sensitive electronics in your wheels, so it’s best to consult with a pro mechanic in your town or online first since this test risks harming the delicate electronic gizmos in your Audi TT RS 8S.

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 TT RS 8S. You find all the information you need about your specific vehicle by searching online for something like “Audi vin number“, 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.

If you question if the starter motor is the root cause for your TT RS 8S refusing to start up, listen carefully for a clicking noise when you turn the ignition key. If present, but the engine does not turn over, the starter motor likely needs 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 TT RS 8S

If you suspect a fuel system issue might be causing the no-start, tune your ears for the fuel pump hum when you turn the key to “on” before attempting to start the car. The pump should make a quiet humming for a few seconds. Should no such quiet hum be audible, the fuel pump could be defective. Problematic starting, stalling, or lagging acceleration may also stem from a blocked fuel filter. Filter and pump issues normally need a skilled mechanic to inspect and repair them properly, often involving fuel pressure testing and precise diagnostic equipment. Later in this article, I detail the best ways to get help from a local Audi mechanic near you. 

How to Fix Electrical or Wiring Problems in an Audi TT RS 8S

If you suspect it’s an wiring issue, first examine the fuses for the ignition system, and replace any that have blown. If your TT RS 8S starts after this, it was an effective, inexpensive fix! But if your Audi TT RS 8S refuses to start, even sometimes, the ignition switch itself could be faulty. Dash lights on the dashboard could additionally mean a faulty sensor. These can be complex problems needing a qualified mechanic to identify and properly repair (see below advice on local mechanics).

Preventive Steps

As grandad would say: “An ounce of prevention is worth a pound of cure”. Here’s how to avoid future problems starting your TT RS 8S:

Routine Upkeep of Your Audi TT RS 8S

Regular maintenance on car to prevent starting issues

Regular maintenance is essential to avoiding issues, including oil changes, checking the battery, cleaning terminals, replacing the fuel filter as needed, and having a mechanic examine the car regularly. If confused about maintenance for your model, ask a mechanic locally or online for clarification.

Drive Your TT RS 8S Regularly

If your Audi TT RS 8S happens to sit unmoved in the garage or driveway for extended times without being driven, the battery can weaken as it is not being charged up by the engine running, through the alternator. Try your best to drive your car regularly to maintain a charged battery. If you remember you haven’t driven your car in a while, take it for a quick spin around town to ensure there is still a charge left.

Note: Letting the battery completely drain is also bad for its longevity, so try to avoid that.

Take Notice Of Warning Signs

If you notice any irregular 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 despite putting in real effort on your own, you still can’t get your car to start, 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.
