Top 5 problems with Audi Models

Owning an Audi is a life goal for many avid drivers. The luxury vehicle brand boasts some of the best car interiors on the market for added comfort and style. Not only that they are famed for being tech heavy and if that wasn’t cool enough…….Iron man drives an Audi! But, as with any vehicle, there are some familiar problems common with the Audi. In this article, we’ll go through the top 5 problems with Audi models. Look out for these top 5 problems with Audi models on your new car to ensure you keep damage to a minimum.

But, as with any vehicle, there are some familiar problems common with the Audi. For Ford it’s common to see rusting bodywork, Fiats are prone to cabin leaking. Every mass manufactured car has its flaws but it doesn’t mean we love them any less. If you read up ahead of time and know what common problems to look for then you can usually catch them before it starts to cost you the earth in repair bills. In this article, we’ll go through the top 5 problems with Audi models. Look out for these top 5 problems with Audi models on your new car to ensure you keep damage to a minimum.

Oil Leaking

It is common to experience a burning oil smell coming from the engine of an Audi. This is because they are known to experience oil leaking from the valve covers or gasket seals. Leaking oil can be a fire hazard and there’s a risk to the electronics of the engine. The oil will eventually eat through the wires and damage electrical connectors and control modules. The longer this is left unnoticed the worse the damage will be and the more expensive it will be to fix. Not only that, the engine needs oil to run and if it is leaking rapidly then it could be a disaster.

Exhaust Leaking

Another leaking part that’s common in Audi is the exhaust. This is because most Audi’s have a flexible join in the exhaust which sits between the down-pipe and catalytic converters. The joint gets weathered over time and begins to leak. The tell tale sign is the deeper exhaust sound. Admittedly it does sound cool and makes the car sound even more beefy than usual but the result of trying to fix it too late can be expensive. This is because the leakage can cause O2 sensor codes, check engine light and cat efficiency problems. If there is resulting damage to the flex pipe it is rather expensive to repair because it is part of the catalytic converter in most models. If caught early there is a solution which just replaces the flexible joint and this is a lot cheaper.

Rattling Engine

You may notice that during the cold weather you hear a rattle or knocking noise coming from the engine. The sound usually lasts for 1-2 seconds after the engine has started. It is caused by the camshaft chain tensioners or camshaft adjusters. The camshaft adjustment is a hydraulically manoeuvred part controlled by engine oil pressure. So if the oil pressure drops due to cold weather or the car not being used for a while, the camshaft adjusters must be built up as quickly as possible for the pressure to build back up into the oil sump. During this time, a rattle or knocking noise may be noticeable. This noise is normal at cold engine start and will last until the oil pressure is fully built up, which takes about 1-2 seconds. In the event the noise continues significantly longer, we recommend taking your car to a garage for analysis.

Smelly Heating and Ventilation System

If your car has been sat for a few hours some Audi drivers complain of a musty odour in the car from the heating system. While there are a number of sources for odour in a car the most common is mould growing inside the air conditioning ducting system. Mould spores are present in the air and gather with moisture during the air conditioning process. In the heat of summer or warmer climates, they grow rapidly. It is not a problem that can be eliminated completely, however, a cleaning system applied once or twice a year will manage the mould build up and remove the odour.

The Check Engine Light

There are two common faults with the check engine light on an Audi – if the car is running rough and then misfires. Misfires can be isolated to a single cylinder or occur randomly across multiple cylinders. Multiple misfires have many possible causes. The most common being the ignition coil. Audi has recalled several cars in the past to replace the ignition coil for free.

If the engine light comes on and you’re not experiencing any performance issues then the problem is commonly emissions related. Audi is known for leaks in their vehicles emissions gas recycling system. There are a number of common reasons that can cause this situation. Worst case scenario the catalytic converter isn’t performing efficiently so the exhaust gasses are not being cleaned properly. Catalytic converters are covered under warranty for 8 years or 80k miles with Audi but if you are out of this warranty period the cost to replace this part is huge.

There are a few other common problems with Audi models to be aware of when you own one of these magnificent cars. These include –

A clunking sound when making sharp turns  

Turn signals stay on or won’t come on at all.

Coolant leaks or low coolant light is on.

The boot doesn’t always close automatically.

Turbo cars sometimes blow smoke.

Despite all of these common problems, Audi remain one of the most popular car brands in the UK. It’s easy to see why though. Their stylish designs, superior interior finishes, impressive technology, the range of models and fuel economy are certainly cause to sit up and take notice.

When you come to choose which model of Audi will best suit you it’s worth being mindful of these common problems. A newer car will be less likely to develop some of these problems. If you’d like a new Audi but the price tag to buy is a little too rich in up front costs and repayments you could consider obtaining a lease
