There are a number of faults that can put the 185 D5 into a not well documented "restricted power" mode (rather than limp mode) and this doesn't put any lights or messages on the dashboard.

The scenarios I have personally experienced are intermittent or complete failures of the DPF and Catalyst temperature sensors. In this mode the revs are limited to around 3k rpm, but under that it will drive okay so it's possible not to notice - even on an auto - if you are just pottering about.
Yes , yet another Myth which circulates around the internet ...
