Jb in a lease bmw? - BMW 3-Series Forum (F30 / F32)

Dan_335i · 08-24-2012, 07:02 PM

What happens if dealer found the jb4 installed on leased f30?

Will they tell u to buy the vehicle outright or charge u a fine?

justinnum1 · 08-24-2012, 07:10 PM

Warranty most likely is voided for things on the car that might be related to the power gain, and I was told by a dealer that they wouldn't be able to sell the car as a CPO vehicle after it's returned at the end of the lease. That has to cost them some money. Not sure how they recover that. If your center console gets stuck and you have a tune, or a headlight goes out, obviously they'll cover that.

I personally would wait for a handheld OBII style plug in device that will let you easily remove/install the tune. At least that's my plan. I had a dinan tune on my N54 but it was a nightmare because I had to keep getting the car reflashed every time BMW came out with a CPU update which seemed to be at least 2 times a year.

I know ESS made one for the E9x N55 models that was about $1000 and made about 40rwhp/60rwtq over stock....or about 45-50hp/70-75tq at the crank over stock.

i mostly think they will tell you to buy a car outright because you damaged the car which is the property of bmw?

remove it before you take it for service... Clear the codes using the CAN tool...

E46M54325Ci · 08-25-2012, 11:07 AM

For the e9x cars those that tuned them had a Bavarian Tech (BavTech) code reader that was capable of not just reading the universal codes but BMW specific codes and was capable of clearing them. This is ABSOLUTELY CRITICAL because BMW developed "shadow codes" that are hidden and, if triggered, will tell the dealer that the car has been tuned. There was also a possibility that for cars with BMW Assist these codes were TRANSMITTED TO BMW before they could be cleared. I don't know if that's true or was ever resolved, but the shadow codes are FOR REAL.

For me this was all too much and I just decided against any non-factory tune altogether. Be careful before and after you tune. Just taking it out probably will not be enough. Too many people have had their warranties voided after removing the tune because they failed to clear the shadow codes. Have fun but be careful. The BMW warranty is worth its weight in gold, but its as fragile as an eggshell.

This. Its such a quick install, and once you do it a few times there's no reason why you can't do it in about 35-45 minutes.

You'll be set!

According to Ballz, on the F30 it's even faster.. took him 5 minutes

Wow that's pretty excellent. We haven't done an F30 tune yet, and I was going from my experiences installing on an N54 E90.

Good to know though!

turtle335 · 08-30-2012, 02:57 PM

How much +HP total if i installed it?

s1k0ne · 11-04-2012, 08:49 PM

Hi,

i was wondering if any reputable shop installed the tune and cleared it in the F30 without any problems.

Thank you

My car has BMW assist, my question is can you deactiveate this service? I plan on doing a tune and I obviously dont want them to know so can I eliminate this monster that they created to know everything about our cars while theyre in our possesion.

omer · 11-04-2012, 09:40 PM

You guys make it such a big deal, install the JB and when you take it for service shut it off or leave it on. I have a 2009 335i face lift for almost 3 years and I have the dual cone intake jb3 then went to JB4 also have straight pipe, hid fog lights paint my top of the car black plus other shit. And I bring my car to any dealer for service no one has said shit to me. I'm getting my 2013 335 I M next week after this bitch Sandy came thru and everything is in hold.

Im just trying to find out about this bmw assist and if they really see the shadow codes when the car has a tuner in it.

Same thing i'm wondering about. Maybe the poster above had a dealership that didn't care about modified cars? Also, with the mods that you did including your painted roof, you had your car purchased right? No way a dealer would allow a painted roof.

The op painted his roof not me, and I dont think they would really care about a painted roof. But dont go to them and complain there is a rust bubble forming on the roof or the paint is fading or what not. You can just pretty much expect to be turned away at that point. But like everyone else said it all depends on what part is affected. Youre painted roof will have nothing to do with a defective window switch for example so you would have no issues there.

If this whole BMW assist thing is true and it cant be disconnected, I think everyone is pretty much screwed as far as tuning goes, unless you are willing to give up your warranty. We all may be monopolized into BMW's PPK

I also know there are a few members on here already with a JB in their cars, maybe they can chime in and tell us if they have BMW assist and how/if it does send shadow codes to BMW. Maybe this can be bypassed or tricked as well.

My car Is a lease. I bring my car to the biggest dealers In ny and nj. I had my Jb in the car I changed fuel pumps my turbos burned they replaced everything. I can only speak for my self I really didn't have Any problems. My car is at the port in nj and I can't wait to get it and install the Jb.

Which dealer? Prestige?

I have never heard of a Warrenty Void on a Lease.

Im not sure how BMW scan tools work at the dealer, But im a tech at toyota and if we check codes it will send them straight to toyota so its true...

Basically true plus the techs or service people dont really care or know its a lease. As long as you dont come in with CEL on or engine problems i would not worry at all about leaving the JB tune in. A tech is not going to waste his time to check if it has a tune unless you have a engine related concern.

RollingLower42 · 12-11-2012, 11:09 PM

I talked to a service technician at BMW and straight up asked him if I brought a modded car to them would it be a big deal?

He basically said they do not care about mods when it comes to simple services like oil changes.

So basically if you have your car tuned for a regular service, you should be cool. Just take it off and clear it before taking it for warranty related issues or engine related issues.

I just ordered my JB4, so I am excited to be getting some extra HP out of it.
