Audi Q5 — service and repair in Espoo

The first generation of the Audi Q5 was presented in 2008. The model took a place between the Q3 and Q7 and quickly became one of the brand’s key SUVs.

The second generation was presented in 2016 and reached the market in 2017. It received a new platform, a lighter body, modern engines and updated electronics.

The third generation of the Audi Q5 was presented in 2024 and is built on the new Premium Platform Combustion. Audi offers it with petrol and diesel engines, the mild-hybrid system MHEV plus and new electronic systems.

The main generations are:

The first-generation Q5 is widely represented on the used market today. You will find 2.0 TFSI, 3.0 TFSI, 2.0 TDI, 3.0 TDI, S tronic, Tiptronic and quattro.

For a car more than ten years old, service history is especially important. With age the following may need attention:

The second generation became noticeably more advanced. It introduced modern TFSI and TDI engines, an updated S tronic, quattro ultra, the plug-in hybrid TFSI e, a digital instrument cluster and an expanded set of assistants.

On the Q5 FY it is especially important to consider the specific all-wheel-drive configuration. Not all versions use the same quattro system, so the service schedule depends on the engine and transmission.

The third-generation Audi Q5 received the new PPC platform and MHEV plus on some engines. Audi also revised the electronic architecture and expanded the list of assistants.

The new generation is available as a Q5 SUV and Q5 Sportback, as well as in the more powerful SQ5 version.

When servicing a new Q5 you cannot automatically apply procedures from the previous generation.

The Q5 is often used as a family car and may cover significant distances. In Finland additional load comes from cold starts, road salt, snow and ice, temperature swings and heavy suspension loads.

It is worth checking regularly:

Across Q5 generations you will find 2.0 TFSI, 3.0 TFSI and V6 TFSI on higher-powered versions.

For TFSI it is important to monitor oil level, spark plugs, coils, the turbocharger, cooling system, crankcase ventilation and timing drive.

Diagnostics are needed if:

On some early 2.0 TFSI engines elevated oil consumption is more common. However, you should not draw conclusions from a single engine designation alone.

Causes may include external leaks, crankcase ventilation, the turbocharger, piston rings or general wear.

If oil consumption has increased, the cause should be identified rather than simply topping up.

Many petrol Q5 engines use a chain-driven timing drive.

Reasons for inspection include a metallic noise after a cold start, cam phasing faults, poor starting, unstable running and Check Engine.

Not every noise means a full chain replacement is required, so diagnostics should come first.

On the Finnish used market 2.0 TDI and 3.0 TDI are widely represented.

A diesel Q5 suits high mileage well, but urban use can place load on the exhaust aftertreatment system.

Diagnostics are needed if:

The particulate filter gradually accumulates soot and ash. If the car often drives on the motorway, regeneration usually completes well. On short trips the process may be interrupted.

Symptoms: raised idle speed, fans running after shutdown, higher consumption, more frequent regenerations, a DPF warning and reduced power.

Diagnostics check soot and ash loading, differential pressure, temperature sensors, EGR and engine operation.

The EGR system becomes contaminated over time. Possible symptoms: Check Engine, power loss, unstable running, frequent regenerations and limp mode.

On some TDI engines the EGR cooler should also be checked. If the coolant level is dropping at the same time, this is especially important.

Modern diesel Q5 models use an SCR system. A fault may be linked to the NOx sensor, pump, injector, heater, level sensor or wiring.

If a countdown to a no-start condition appears, diagnostics should be done in good time.

Many Q5 models use an S tronic gearbox. It has two clutches and differs from a classic automatic.

Faults may involve the clutches, mechatronics, oil, adaptations or the mechanical section. For gearboxes with a scheduled oil change, servicing must be carried out on time.

Inspection is needed if:

Some versions use Tiptronic — a classic torque-converter automatic.

Oil service history is especially important on high-mileage cars.

Diagnostics are needed if:

All-wheel drive is one of the main features of the Q5, but the design varies. Depending on the generation you will find classic permanent quattro, quattro ultra and electronically controlled multi-plate systems.

Therefore one service schedule cannot be applied to every version.

Diagnostics are needed if:

On part of the second generation quattro ultra is used. The system can disconnect the rear axle to reduce losses and reconnect it when needed.

During diagnostics it is worth checking the clutch, electronic control, oil, sensors and stored faults.

For all-wheel drive it is important to use tyres of the same size and similar wear.

An all-wheel-drive Q5 has additional drivetrain components. Possible symptoms: vibration on acceleration, a drone, knocking, a jolt when moving off or an oil leak.

A similar noise can also come from hub bearings or tyres, so the source must be identified first.

The second-generation Q5 was also built as a plug-in hybrid. That version combines a petrol TFSI engine, an electric motor, a high-voltage battery, S tronic and quattro.

Diagnostics must take both parts of the powertrain into account. Work on high-voltage components requires appropriate qualification.

Inspection is needed if:

The cause may not be the battery itself. Check the cable, charging station, connector, port lock, 12V battery, on-board charger and high-voltage faults.

Sometimes a weak 12V battery can prevent the charging process from starting.

The Q5 has a complex thermal management system. Causes of a dropping fluid level may include the pump, thermostat, hoses, radiator, EGR cooler or heat exchanger.

TFSI e models also have separate cooling circuits for the high-voltage system.

Coolant should not be topped up regularly without finding the cause.

The Q5 is heavier than Audi saloons and is often used on poor roads. Over time control arms, bushes, anti-roll bar links, dampers, ball joints and hub bearings can wear.

Inspection is needed if knocking appears, the car holds its line less well, the steering wheel vibrates or tyres wear unevenly.

Some well-equipped Q5 models use adaptive air suspension. It allows ride height and damping characteristics to be changed.

Fault symptoms: the car settles after parking, one corner sits lower, the compressor runs too long, a suspension fault appears, or the body will not change height.

If the compressor switches on frequently, a leak must be found.

On the Q5 hub bearings see high load because of the vehicle mass and large wheels.

The main symptom is a drone that increases with speed. On quattro a similar noise can come from the drivetrain, so the source must be identified before replacement.

The Q5 is a fairly heavy car. In Finland salt also accelerates brake corrosion.

On TFSI e regenerative braking must also be taken into account.

Inspection is needed if:

Modern Q5 models use more and more electrified systems. The new third generation applies MHEV plus on some engines.

If many faults appear at once, check the 12V battery, charging system, MHEV components, converters and stored faults.

A modern Q5 has a large number of electronic control units. Possible issues: MMI restarts, the screen does not switch on, sound disappears, Bluetooth is unstable, the camera does not start, assistant faults appear.

Sometimes several faults are caused by low supply voltage.

The Q5 can be equipped with adaptive cruise control, Lane Assist, Audi pre sense, blind-spot monitoring, cameras and parking systems.

After windscreen replacement, body repair or suspension work, calibration may be required.

If the air conditioning no longer cools, the cause may be a leak, the compressor, condenser, pressure sensor or fan.

If the system needs regular top-ups, the leak point must be found.

The Q5 Sportback is distinguished by a more sloping roofline. Technically most systems are similar to the regular Q5.

It is also worth checking the powered tailgate, seals, rear camera and water ingress into the boot.

The new Q5 generation is also built as a Sportback.

The SQ5 is the sporty version of the family. It has a more powerful engine, a reinforced drivetrain, high-performance brakes and a sport chassis.

A car with modified software may place higher load on the transmission.

Before purchase it is especially important to check:

Before purchase it is worth checking cold start, control-unit faults, the engine, oil consumption, timing drive, turbocharger, cooling system, DPF, EGR, AdBlue, S tronic or Tiptronic, quattro, propshaft, suspension, air suspension, brakes, MMI and assistants.

For TFSI e also check the high-voltage battery, charging, hybrid mode and high-voltage faults.
