The Fawlty Towers star appeared in Weatherfield last year for a guest stint as Norris Cole's (Malcolm Hebden) estranged half-brother Ramsay Clegg.
In a new interview, Sachs confirmed that he continues to enjoy Coronation Street as a fan but appreciates some characters more than others.
The Mirror quotes him as saying: "Sometimes my wife and I say, 'That's good'. Other times we shout, 'Get rid of him!'"
However, the veteran actor would not name any specific characters who are currently irritating him.
Sachs will be seen in Sky1's new Terry Pratchett adaptation Going Postal next month.
