Issues with the timing chain

[spiezen]

Greetings to everybody, I am new to the site as I am seeking to acquire an Evoque; however, I have read that the Ingenium engine may experience issues with inadequate regeneration and premature timing chain deterioration.
If I get a vehicle with little mileage and a comprehensive service history, can I circumvent these problems?

Some Diesel Ingenium vehicles have reached 100,000 miles without troubles, while others have barely achieved 15,000 miles. Later versions from 2022 onwards may perform better. It is possible that their reliability is inferior to other manufacturers.

A low mileage does not inherently indicate superior condition; it may reflect numerous short trips, potentially utilising worse grocery fuel. Additionally, a full service history merely signifies adherence to the necessary biennial servicing, during which the oil may have gradually deteriorated.

Users of Diesel Ingenium on the Forum opt for annual oil and filter changes between services and either utilise premium fuel or additives to potentially enhance engine combustion efficiency.


I possess my second diesel Ingenium Evoque and will undoubtedly opt for a third if they still available at that time. I believe it is an excellent unit with substantial torque; nonetheless, it requires proper maintenance.

I was unaware that fuel from supermarkets differs from that obtained at petrol stations.
Two years between services is excessive; I schedule mine every eight to ten months.
I might not have been deterred from purchasing an Evoque, but I regret having read about the issues associated with it.

I simply need to wait for the appropriate opportunity.

This issue frequently recurs on this Forum, and utilising the 'Search Community' tool will provide numerous discussions from previous years. I recall that the most persuasive argument came from a retired member of a major refinery, who stated that premium fuels contain additives introduced during the refining process, whereas supermarket fuels consist of inferior byproducts. It was noted that diesel engines may reportedly operate on cooking oil.
My only knowledge is that during the initial years of our prior Evoque, I utilised retail fuel, and in 2019, I encountered a 'DPF full' problem that required a forced regeneration. Subsequently, I utilised premium fuel (first BP Ultimate, followed by Shell V-Power) and have encountered no additional issues. Given that I only drive approximately 3,000 miles annually, I consider the additional operating expenses to be a reasonable compromise.

My annual mileage is comparable to yours, hence I concur that the additional expense will be justified, as will the increased frequency of oil changes.
Thank you for your contribution.
