Weird start-up noise

[Lager shandy]

How did you get on with this issue and lexus any updates ?

Hi just wondering if any updates on this. PEA based injector cleaner seemed to have helped ours, fine for 3 months, but recently come back, so trying again.

From looking online, I'm guessing the sound is a result of knock from clogged injectors. 

The cam rattle is different from the videos and reports I've read.

I've just come across this thread. I'd be interested in any updates as to how things have gone.

Hi all, has anyone got any advise regarding this issue? My 2013 RX450H had just started doing same noise for about 10 secs upon starting. Thanks.

No joy on ours I'm afraid, new injectors I am told "might" fix it, looking on US forums it does point to this. However the tech note from Lexus says check the injectors, if they look clean them that's not the fault. 

Due to covid and wife loosing her job we decided to trade in for a little EV so never persued, but my next step was going to send the injectors off for cleaning, £400 Vs £2k+ for new ones.

 

Good luck, please post back any updates.

 

also if your anywhere near Sheffield, lex tech autos is with contacting, they did quite a bit of work on mine.
