Yes, it's best to delete youtube video. I deleted my posts here that were discussing that issue.

Nah, relax. The bend rod noise won’t be like that.

I think that ticking sound may come from injectors, and that’s the best case scenario. The worst?? Turbo failure also makes that sound. And let’s hope it’s not......

No choice

I don’t know what to say.....Sorry to hear that, hope your mechanic was wrong. Anyhow, flash stock map back, go to dealership, there still a chance they won’t notice your car was tuned before.

Keep us updated, there must be a reason for stage 1 map that can make a rod bend.
Bad gas, plugs, or dirty oil deposit? I do hope it’s just a bad injector or lifter, and a small pain to pay.

Fingers crossed guys. I will probably drop the car tomorrow so ...

Stumbled upon interesting situation on BM3 facebook group page. One guy was flagged by a dealer for aftermarket tune (BM3). He got engine issues too (his timing skipped). Dealer refused to fix it under warranty. He threatened with court, eventually dealer agreed to fix it for free under warranty, but said in the future the car will be inspected by a field engineer for every claim. The guy got lucky I guess.

Yep, pretty normal. Sounds like mine both before and after tune. This is the typical BMW lifter tick.

Thanks god!! Such a relief!!
I kind of regret to lose $5k extended warranty for this stupid tune.
Now, I’m about to run back stock tune for a while, until these issues sorted out.

Too late my friend. Once you dme programmed bmw will find that. Just pray that nothing gonna happens with you engine. I knew the risk. My mechanic told me dont buy n63tu. They are weak. I did not to believe it but $hit happens. And when does " why always me " So ... i wish everyone good luck with tuned N63tu

Sounds totally normal to me , just like my stock one sounds and like others have mentioned very common with other BMW engines as my n54 sounded very similar.

I didn't have your luck, they just called and said misfires in cylinder5, but only replaced the plug and coil in that affected cylinder under CPO, not all of them - so need to drive there again when the next one goes and pay another 50.

You can always pay and let them change the rest of coils and plugs, while they replace the faulty one. Those will fail you pretty soon.
It may cost you a bit, but consider the time saving, and you don’t have to worry about it all the time. It worth it!
