Carbon canister is part of the 4 year service.
It's 4 years since I had the "proper" 4 year service, and I was advised that it was not necessary to do the lambdas or the carbon canister this time. I did do both 4.5 years ago (2019). Previous to that, I presume they were done by the first owner...
It's always more than you wanted to budget for, more than you expected to budget for and frankly it's the gift that keeps on taking!
But I love it :)

I should know how to understand this since I work in banking. In 6 months time the market expects the rate to have dropped to 1.21 USD / 1 GBP. Today's rate is 1.25. That's disappointing!
