The Toyota Aygo and its near-identical sister cars the Citroen C1 and Peugeot 107 have provided super-cheap transport for countless thousands of buyers. And on top of that, they did so while providing a chic and cheerful ambience that attracted loads of people, from young, new drivers to those with a few more miles under their belts, but who still wanted to look trendy.
The cars were jointly designed by the three manufacturers, and to all intents and purposes are the same, apart from minor trim differences. And that means that if there are niggling issues on one of them, then those same niggling issues are quite likely to afflict the others.
But don’t worry, because Haynes can help you sort out any problems, by guiding you through each and every stage of diagnosis and repair. Just follow the steps in your Haynes Aygo manual or Autofix.
What recalls has the Toyota Aygo been subject to?
Almost 175,000 examples were recalled because the accelerator system could fail to return to idle as quickly as it should.
After that, 88,784 cars were recalled because the tailgate glass adhesive could fail, allowing the glass to detach and smash.
Then 2128 cars were recalled because the front shock absorber rod could fail, affecting directional control.
A further 604 examples were recalled because of a faulty weld on the rear axle, which could also cause a loss of control.
And a small number of cars were recalled because it was found that their fuel tank did not conform to specification.
What common problems does the Toyota Aygo Mk1 have?
The Toyota Aygo is designed to be driven around town, in the cut and thrust of traffic, so it’s annoying that its clutch can be prone to failure.
And a number of owners have voiced concerns about a rattling noise being produced by the exhaust pipe in their car.
Meanwhile, the Toyota Aygo and its sister cars were never meant to be high-performance machines – traffic-light races are pretty much always going to end in defeat, but a fuel issue can cause even the tepid performance to tail off a bit more.
A number of Aygo owners have also complained about being left stranded when the gearchange on their car ceases to operate, and finally, faulty power steering has caused a few people to be unhappy about the amount of effort their Aygo demands of them.
Has the clutch failed in your Toyota Aygo Mk1?
Several owners of the Toyota Aygo and its sister cars the Citroen C1 and Peugeot 107 have reported a squeaking noise emanating from underneath as the clutch is released. This is accompanied by a difficult gearchange.
The problem is either a broken clutch release bearing tab or a worm clutch pressure plate diaphragm spring. Either way, you’ll need to replace the clutch.
The good news is that this entire procedure is covered in your Haynes Aygo manual, so it’s just a case of gathering together the bits, plus the correct tools and setting to work. It’ll take a few hours, but you’ll be back on the road with a fault-free clutch and easy gearchange.
Why is your Toyota Aygo Mk1 exhaust rattling?
Nipping in and out of traffic-clogged streets naturally means a lot of slowing down and speeding up. However, the Aygo and its sister cars (Citroen C1 and Peugeot 107) can suffer an issue that causes something inside their exhaust pipe to rattle when accelerating.
The pipe itself doesn’t cost much, so it’s best to simply replace it. To that end, you’ll need to raise the rear of the car and set it on axle stands, before removing the faulty piece of exhaust (part number: 17430-0Q013) and the rubber mount it hangs from (part number: 17588-0Q010), then replacing both with new components.
As ever, we’ve carried out this tax for the Haynes Aygo manual and Autofix, so simply follow the steps and you’ll be fine.
Does your Toyota Aygo Mk1 feel lethargic?
Ducking and diving. Bobbing and weaving. Cutting and… lumbering? Yes, the Toyota Aygo (and its sister cars the Citroen C1 and Peugeot 107) can suffer an issue that causes its already-unthrilling performance to become even slower.
So, your first port of call (literally) should be the OBD socket. Plug in a fault-code reader and if it generates the code P0171 then you’ll know that the fuel system is running too lean.
This is because the fuel feed lines have become corroded and blocked, and the best way to fix things is to replaces the lines (part number: 77240-0H010).
Your Haynes Aygo manual can guide you through each step of how to remove the old fuel lines, and then will show how to fit the shiny new replacement items. And your Aygo will be back up to full road-melting potential once more.
Has your Toyota Aygo Mk1 gearshift packed up?
Part of the joy of the Toyota Aygo is being able to snick between the ratios as you deal with traffic that isn’t as on the ball as you are. However, the manual-transmission Aygo is known to let you down on occasion, by suddenly refusing to shift gears.
The problem lies with the gearshift control cable assembly – one of the control cables can suddenly fail, leaving you with no gearshift.
The only solution is to replace the gearshift cable assembly (part number: 33820-0H010), which is a procedure that’s covered in detail in the Haynes Aygo manual. Just buy the part, follow the steps (it’s quite simple) and you’ll soon be back to your cog-swapping best.
Does your Toyota Aygo Mk1 have power steering problems?
In a car designed to nip round corners and be easy to park, heavy steering is somewhat less than ideal. However, the Toyota Aygo and its sister cars, the Citroen C1 and Peugeot 107, can be prone to such a problem.
First up, you’ll need to plug in a fault-code reader. If this displays the code 1544, then the problem lies with the power steering control unit. Fixing it isn’t possible, so you’ll simply need to replace the unit as a whole.
However, it’s easy. The unit is located behind the fascia, just below the headlight adjustment switch. After disconnecting the battery, you’ll need to deactivate the airbag system, then unplug and unbolt the power steering ECU, before replacing it with a new unit, tightening everything to the correct torque and plugging everything back in, before reconnecting the battery. The Haynes Aygo manual can guide you through every stage of the process, which won’t take long.
