Timeing chain replacement auris 1.2 petrol

[Tiger1899]

Hi need to replace timeing chain on my toyota auris. Icon tss vvt-1 5 door hatchback. On a 67 plate. Still has warranty on car. How ever.  Warranty will not pay out for this as my local garage had used correct oil. But warranty company is saying one off oil changes should have been a 20 grade oil rather than the 30. My question is does the whole engine need to be taken out to exchange chain. My main dealer has stated if they were to take on the work they would need my car for 2 weeks & at a cost of £ 2800. Am I belong ripped off by toyota. Any advise appreciated.

Presume you meant 'incorrect oil'.

The owners manual would state that the 'preferred oil would be 0W-20. 5W-30 may be used, but should be replaced by 0W-20 at the next service.'

Check your owners manual, the oil used, 5W30 can be used. 

First time i hear that engine needs to be removed to do a timing chain replacement, who told you that?

The quoted price is unreal, such replacement could be done in a day, and much under the quoted price, but dealer prices are always otherworldly. 

Besides, based on climate, and weather, sometimes using different viscosity oil is better, like during winter it's better to have less viscous oil, to give you better protection until engine is warmed up, as is flows better, and in summer thicker oil, for better lubrication.

Nothing is written in stone, check the owners manual, the info Frosty wrote should be true, it says it's also allowed to use 5W30, i'd fight them and ask to pay for it.

Why does the chain need changing ? Have you had a second opinion ?

Yes, it says 5W-30 can be used, but it should be replaced with 0W-20 at the next service. 

0W-20  began to be used in the Auris from late 2008 with the introduction of the Optimal Drive engines.

Second opinion from another person garage should be the next step . Timing chains on Toyota engines are not serviceable parts and they are fitted for life or at least 250+k miles. Wrong type of oil in a short run can not cause chain to stretch , wear out or anything unless been used 20w50 classic cars oil 🤭. If the car has a timing issue caused by the chain there may be something else wrong (faulty) that has caused all that to happen, or perhaps the car been abused like missed shift a gear or anything similar. 67 plate it’s a fairly new car to have all that drama. 
Good luck

Other queries include:

What mileage has the car done?

Have the correct service intervals been adhered to? Eg servicing every 12 months or 10,000 miles, whichever occurs first.

Either or both may have a bearing on the warranty.

I am shocked that 1.2L Turbo need timing chain. It is relatively new engine, 2015 model.  From any Toyota owner manual, It is say clearly 0W-20 or 0W-16 in new Corolla.  You can use other grade of oil but need to change it to 0W-20 in the next oil change or better just use only 6 months/5k miles instead.   Timing chain in 4 Cylinder Toyota are made for life, some last 400k miles without any issues since 2003 Corolla.   Only the VVTI sprocket in certain year range may have problems but not the chain, or timing chain guides.  The tensioner in 1.8L may leak some tiny oil that barely drip in 1 year. 

The Turbo 1.2L is a kind of Odd engine, the only Toyota gasoline engine with direct injection only and Turbo. I was quite pessimistic at that time.  The one in Lexus IS was also direct injection only and it is still one to avoid in used car market.   I wish  1.6L 3 cylinder Turbo in Yaris GR will be an option to replace 1.2L Turbo. 

As an owner of Toyota, there is nothing more important than changing the Oil and filter very regularly. 10k miles/1 year in normal condition. 5k miles/6 months if we drive 50% or more in city with stop and go traffic, towing, climbing mountains, always full load with 5 people and luggage, never go in highway with 60mph or more at sustain speed in more than 30 minutes.  Oil change, clean the underbody and coat it with fluidfilm to prevent rust are the best investment in owning and keeping Toyota.  Everything else are not that critical. 

Change brake fluid every 5 years in non-hybrid, 8-10 years in hybrid, 10y/120 k miles sparkplugs, 60k miles transmission fluid, 30k miles differential fluid, clean and lube the brake slider pins every 5 years.  7 y/150k miles coolant SLLC.  Yes, I am serious about the brake fluid change in 5-10 years, it is often unnecessary for Toyota unless the car has calipers problem from flood, corrosion, or seals.
