Hi,
Just wondering if anyone else has an odd rattling noise on startup when cold, I believe it will be the ancillaries, but not 100% sure. Vehicle is a 2018 gti+
Thanks

Re: Engine rattling on startup until warm
Difficult to diagnose an engine noise on a forum. Has it always rattled on start up or only recently started? Presumably you’ve checked your engine oil level and it’s OK, so insufficient oil can be ruled out as the cause of the noise? An engine can rattle for a second or two on starting as the oil pressure builds. Can’t say I’ve noticed any odd rattling noises on start up in my 2020 GTI+.
It could be the fuel injectors (more of an tappety noise than a rattle though, and continues after start up). If so, it’s not uncommon and considered to be normal. Not all cars do it though; some cars’ fuel injectors are more tappety than others - those on my car are pretty quiet.
However, as said, it’s difficult to diagnose from a forum post whether the ‘odd rattling noise’ is a normal characteristic or if it’s something you should get checked out.
