So my Astra J 2013 1.4 was making a chirping noise while idling, removing the oil dipstick stopped the sound. After replacing the rocker cover, still made no difference. The actual cause of it was the Crank Pulley Seal. To get to this seal you need to support the engine, remove the left engine mount, take off the cambelt etc and behind all that you'll see a circle seal. Replacing that solved it instantly. It had a small leak causing air to get out. The video above isn't my video, but is the exact same noise and had the same fix. Hope this helps anyone who has this annoying noise.

hi there i have the same year car and the same engine too i have an issue with my brake warning light i also have the audible alarm too i plugged in opcom faulty brake switch same code changed out the switch with no change assumed it was handbrake related and wrong again still no change audio and light went under bonnet disconnected the switch to the reservoir (where you top up) took for a drive no alarm or warning light so i need a new reservoir/master cylinder also have you looked under the car? i had a vibration/tinking noise i traced this down to 2 rotted out screws on the heat shield to the exhaust i fixed mine by undoing bolts and adding a couple of large washers to cover the rotted holes then tightening back up i know thats a long shot but worth a look my car is the same age and has just 73k on the clock so its pretty much similar
