My ABY coupe has a 'belt' squeal noise when starting from cold - a video is attached.
Some squealing can also be heard sometimes when increasing revs during the first 30 to 60 seconds of the engine running, but it goes away after that, and does not squeal on startup if the engine has recently been running, only if the engine has been off for a number of hours.
A change of all belts (timing belt, alternator belt, PAS belt, Air Conditioning belt) water pump and relay roller at the last service did not solve issue (the squeal was there before and after the service).
Any ideas on likely causes or troubleshooting steps?
