VAG TSI/TFSI engines

When the problems with the VAG engines with the control chains became known, I decided to use the 102 HP without a turbo. However, as in the near future a new vehicle might be available, I have the following question: Can someone reliably and professionally provide information about when the (or which) TSI or TFSI engines are no longer prone to coking and no longer have problems with the control chains? Thank you for your help
