Top Toyota Aygo fixes every owner should know
Cheap, practical fixes for the Toyota Aygo faults you actually meet, with rough costs and what a garage will charge.

TL;DR
The Toyota Aygo has common faults such as exhaust issues, air conditioning failures, electrical component problems, brake wear, and timing belt replacement needs. Many fixes can be done DIY, saving costs, but some repairs require professional help. Parts and labour costs vary, so it’s essential to be prepared.
Exhaust System Issues
The Aygo often suffers from exhaust system problems, especially with the rear silencer. A common symptom is an increased noise level from the exhaust.
Replacing the rear silencer is usually straightforward. This is a DIY job if you have basic tools, costing around £50 for the part. A garage may charge £100 to £150 for parts and labour.
Air Conditioning Failures
Many Aygo models from 2005 to 2014 experience air conditioning failures. This can be due to a lack of refrigerant or a faulty compressor.
A simple recharge of the refrigerant can be done at home for about £20. However, if the compressor is faulty, replacement costs can reach £200, with garage labour adding another £50 to £100.
Electrical Component Issues
Electrical faults, particularly with the central locking and window controls, can arise in older models. Symptoms include non-responsive locks or windows.
Checking fuses is a good first step. If the issue is with the window motor, replacement can be done for around £40. Garage costs for this repair may reach £100 to £150.
Brake Problems
Some Aygo owners report issues with the brake system, particularly the brake pads wearing out prematurely. This is common in models from 2006 to 2015.
Replacing brake pads is a manageable DIY task. Parts typically cost around £30. If you choose to have a garage do it, expect to pay £80 to £120.
Timing Belt Replacement
The timing belt on the Aygo should be replaced every 60,000 miles or five years. Failure to do so can lead to severe engine damage.
This is not a DIY job for most owners due to complexity. Parts can cost around £100, but garage labour may range from £200 to £300 for a full replacement.
