Renault Twingo loud noise even when switched off

Car: Renault Twingo
Variant: 1.0
Model Year: 2014

Car makes loud noise even with engine off and key out. At this time radio does not work. Sometimes if you continue driving noise eventually goes and radio comes back on.

Sounds like it's the DPF regenerating and the noise you hear is the engine coolant fan which will run at fast speed till completion . If so you will probably notice excessive heat also . which is normal If you give the car an occasional good, fast drive it will probably complete the regeneration cycle before you stop . The power used when this is happening will probably why radio stops and returns when finished
