recently just grabbed a f30 from the bmw dealership with low miles . Im not really sure how professional the dealership i went to was but im having my own suspicions lol. Should i be worried if they forgot to detune my car and change the spark plugs?

it seems like the previous owner did a tune and called it a day
but honestly since its my first car i cant really tell the difference between
stock and tune

i do have plans to do some modifications soon but i want to get the check ups done before i do anything "i am still under warranty "

[njdangelo]

going to need a lot more info to help you on this one. what car? how many miles? why do you think it's tuned? why do you think it needs plugs? first car or millionth car you wouldn't be able to tell your car had a OTS tune without any baseline experience in the same vehicle.

If you are worried about a tune being on, tell your dealership your concerns and have the dealership flash the ECU to latest software. As far as if the dealership changed the plugs and oil and other items for certifying pre-owned, well, its up to whether the dealership is scrupulous or not and you never will know inless you pull the plugs yourself.

What year and model car? What exact mileage?
Tough to offer help without some specifics

Yeah this is so vague, what year is the car? Sounds like its a CPO if you still have warranty. Having the dealer do a software update is a good idea if you want to wipe any tune or coding, but IMO i would actually want to know IF the car had a tune, not just remove it if there was one...

The dealer should also be able to provide you with the maintenance history. If you ask for it, you can also sometimes get them to provide you with the more detailed info that the service department has access to, not just the stuff that shows up on Carfax for example.

when i posted this i wasn't really sure but now i know 100%. its a 2018 320 previous owner had it as a loaner so i wouldn't be too surprised if they just added a tune .

since im still under warranty should i expect to pay up out of my own pockets or free of charge. I lowk kinda expected the dealership i got it from to do this but it kind of bugs me that i might have a chance of getting denied under warranty depending on the tune ?

sorry for the late response i thought no one was going to answer a boring reliability question .its a fairly new car 2018 320 idk what type of tune this owner put but id rather spend extra on a new tune if it means keeping the car for longer

thanks by any chance will this void warranty i looked into some people saying they had problems with the dealership not working on there cars depending on what type of tune they had.

Whatever you want to know, don't just guess. Ask your seller about it and if you're still unsure, ask somewhere else where you can trust.

no one adds tunes to a loaner

I don’t understand this. Why would they pay for a tune on a loaner? These sentences make no sense.

[tardboi]

If there really is a tune, you need that documented. Drivetrain warranty is likely void

Would a tune make the 320 that much faster? Or is it a matter of perspective, based on the starting point of that car and engine on which the tune was added? I was just curious.

Loaners make excellent test beds.

Tune, test and forget when you turn it in. Makes sense.

[Billfitz]

Not to mention that loaners are given out for service customers to use for a few days at best.

Yes. 320 with bootmod3 and a downpipe is capable of very low 13s in the quarter mile. This is documented.

Thanks. How does that compare to a 330 and 340 with the same type of tune?
