Audi A5 Buyer's Guide: Common Problems and What to Look For
Considering an Audi A5? This guide is crucial reading before you buy. We'll dive into the common issues, repair costs, and potential pitfalls of owning an A5, ensuring you make an informed decision and avoid costly surprises.
1. Most Expensive Problems to Avoid
The Audi A5, while a stylish and desirable vehicle, can present owners with some exceptionally costly problems if preventative maintenance is neglected. Addressing these issues early can save you a lot of money in the long run.
Major Engine or Transmission Failure
A complete engine or transmission failure can easily cost upwards of £5,000 - £8,000 to repair or replace. Look for signs of rough running, unusual noises, or slipping gears. Check service history for evidence of regular maintenance, especially oil changes. A skipped service here or there is not a deal breaker, but if the pattern is clear, walk away.
2. Engine Problems
Several engine issues can plague the Audi A5, particularly the 2.0 TFSI engine. These problems can range from minor inconveniences to major mechanical failures.
Key Points:
- * Oil Consumption: The 2.0 TFSI engine is notorious for excessive oil consumption. This is often due to faulty piston rings. Repair costs can range from £1,500 to £3,000+, depending on the extent of the damage.
- * Timing Chain Tensioner Failure: A weak or failing timing chain tensioner can cause catastrophic engine damage. Listen for a rattling noise upon startup. Replacement costs around £500 - £1,000.
- * Carbon Buildup: Direct injection engines like the 2.0 TFSI are prone to carbon buildup on the intake valves. This can cause rough running, reduced performance, and poor fuel economy. A carbon cleaning service costs approximately £300 - £500.
- * Coolant Leaks: Check for coolant leaks around the water pump and coolant hoses. These leaks can lead to overheating and engine damage. Replacing a water pump typically costs £300 - £600.
- * SpecSnag Alert: Use SpecSnag to check the car's history for any recurring engine issues reported by previous owners. This can provide valuable insight into potential problems.

Urgency
Beware of Neglected Maintenance
Many engine problems stem from neglected maintenance. Always check the service history for regular oil changes and other essential maintenance items. A well-maintained engine is less likely to develop serious problems.
3. Transmission Issues
Both the manual and automatic transmissions in the Audi A5 can experience problems. Automatic transmissions, in particular, can be expensive to repair or replace.
Key Points:
- * S-Tronic (DSG) Problems: The S-Tronic dual-clutch transmission can suffer from mechatronic unit failures, clutch wear, and other issues. Repairs can be costly, ranging from £1,500 to £5,000+.
- * Manual Transmission Clutch Wear: Clutch wear is a common issue in manual transmissions, especially in cars driven aggressively. Replacing a clutch can cost around £800 - £1,500.
- * Torque Converter Issues (Automatic): Slipping or shuddering during gear changes can indicate a failing torque converter. Replacement can cost upwards of £1,200.
- * SpecSnag Insight: Check SpecSnag's data on transmission types and common issues reported by A5 owners. This information can aid your decision-making process and highlight any red flags.

Urgency
Test Drive Thoroughly
Pay close attention to the transmission during the test drive. Look for smooth gear changes, no slipping or hesitation, and no unusual noises. Any signs of trouble could indicate a costly repair.
4. Electrical Problems
The Audi A5, like many modern cars, is heavily reliant on its electrical systems. Electrical problems can be frustrating and difficult to diagnose.
Key Points:
- * Battery Drain: A common issue in many Audis is excessive battery drain. This can be caused by faulty modules, aftermarket accessories, or a failing battery. Replacing a battery costs around £150 - £300, but diagnosing and repairing the underlying cause can be more expensive.
- * Sensor Failures: Various sensors throughout the car can fail, leading to warning lights and performance issues. The cost of replacing a sensor varies depending on the type and location, but typically ranges from £100 to £400.
- * Infotainment System Issues: The infotainment system can experience glitches, freezing, and other problems. Software updates may resolve some issues, but hardware failures can be costly to repair.
- * Central Locking Problems: Issues with the central locking system can be a nuisance and a security concern. Repairs can range from replacing a faulty door lock actuator (£150 - £300) to more complex electrical repairs.

Urgency
Check All Electrical Features
Thoroughly test all electrical features, including the lights, windows, locks, infotainment system, and driver assistance systems. Look for any warning lights on the dashboard.
5. Suspension & Safety Issues
The suspension and safety systems are crucial for a comfortable ride and safe driving experience. Problems in these areas should be addressed promptly.
Key Points:
- * Suspension Component Wear: Suspension components like control arms, bushings, and shock absorbers wear out over time. Replacing these components can improve ride quality and handling. Costs vary depending on the component, but typically range from £200 to £800 per corner.
- * Adaptive Suspension Malfunctions: Models equipped with adaptive suspension can experience malfunctions, leading to a harsh ride or uneven handling. Repairs can be expensive, potentially exceeding £1,500.
- * ABS/ESP System Problems: Problems with the ABS (Anti-lock Braking System) or ESP (Electronic Stability Program) can compromise safety. Look for warning lights on the dashboard. Repairs can range from replacing a faulty sensor to replacing the ABS pump (£300 - £1,000+).
- * Airbag System Issues: Check for airbag warning lights. A faulty airbag system can be a serious safety hazard. Repairs can be costly, potentially exceeding £1,000.

Urgency
Listen for Noises and Feel for Vibrations
Pay attention to any unusual noises or vibrations coming from the suspension. These could indicate worn or damaged components. A clunking sound when going over bumps is a common sign of worn suspension bushings.
6. Rust & Bodywork Concerns
While newer Audi A5 models are generally well-protected against rust, older models and cars that have been poorly maintained or damaged may exhibit rust problems. Bodywork repairs can also be expensive.
Key Points:
- * Rust on Body Panels: Check for rust on the wheel arches, door sills, and around the edges of the body panels. Surface rust can be treated relatively easily, but extensive rust can require panel replacement (£500 - £2,000+).
- * Rust on Undercarriage: Inspect the undercarriage for rust, especially around the suspension mounting points and exhaust system. Structural rust can be a serious safety concern.
- * Evidence of Poor Repairs: Look for signs of poor bodywork repairs, such as mismatched paint, uneven panel gaps, or overspray. These can indicate previous accident damage.
- * Check for Water Leaks: Inspect the interior for signs of water leaks, such as damp carpets or musty odors. Water leaks can lead to rust and electrical problems.

Thorough Visual Inspection
Carefully inspect the bodywork for any signs of rust, damage, or poor repairs. Pay particular attention to areas that are prone to rust, such as the wheel arches and door sills.
7. Pre-Purchase Inspection Checklist
Before buying an Audi A5, it's essential to conduct a thorough pre-purchase inspection. This checklist will help you identify potential problems and make an informed decision.
Essential Checks Before You Buy
- Service History: Review the service history for evidence of regular maintenance, including oil changes, filter replacements, and timing belt/chain service.
- Test Drive: Take the car for a thorough test drive, paying attention to the engine, transmission, suspension, and brakes.
- Visual Inspection: Inspect the bodywork for rust, damage, and poor repairs. Check the interior for wear and tear.
- Diagnostic Scan: Have a qualified mechanic perform a diagnostic scan to check for any stored fault codes.
- Compression Test: Consider a compression test to assess the health of the engine, especially on higher-mileage examples.
- Independent Inspection: Arrange for an independent inspection by a qualified mechanic who specializes in Audi vehicles. This is the best way to uncover potential problems before you buy.
