Hello everyone it's been a while since I've gone on here but anyways here's the run down.

My car was experiencing (at the time issues which turned out to be leaking fuel injectors) and the car would not start and due to unexpected circumstances, i.e. car would not start and I was stranded in the middle of the road needing tow truck assistance. I did not remove the jb4 tune on my vehicle. I had the car towed to the BMW dealership for them to "advise" me on what the problem was. AGAIN THIS WAS NOT A WARRANTY REQUEST, AS MY WARRANTY WAS ALREADY EXPIRED!!

BMW diagnosis it and they come back with the diagnosis of faulty fuel injectors and a faulty fuel pressure sensor. I have them replace the sensor which I end up paying for them to do. That's all I wanted; a diagnosis and replacement of sensor.

Here's where my question is. On my service report the it says:

"53540 FAULTY FUEL INJECTORS. AFTER REPLACEMENT OF FUEL PRESSURE SENSOR FOUND THE BANK 2 FUEL INJECTORS TO BE FAULTY. CUSTOMER DECLINED FUEL INJECTORS. VEHICLE HAS AFTERMARKET TUNER ON DME. RECOMMEND ALL 6 FUEL INJECTORS REPLACED."

First off why are they looking for a tune when this was NOT a warranty claim. I simply wanted a diagnosis and for them to replace the sensor ONLY!!

The reason this concerns me is that I have a wastegate rattle that I want to get done by BMW (since the wastegate & turbo are warrantied for 82,000 miles via the extended warranty BMW NA has provided).

Can I remove the tune, clear the codes and go in for it and have it done? And how do I know if my warranty is void or if my VIN has been flagged? Should it say voided warranty on my service report?

I really do not want to take it in and then get hit with the BMW arm and a leg diagnostics fee. Please, anyone with any experience regarding these things would be helpful!

You kind of answered your own question there. They are noting the tune so that if you try and claim something on warranty they will have that record. You are probably dead to rights now as they have proof that you have an aftermarket modification that directly impacts the turbos.

Did you turn the JB4 to map0?

You have other noticeable mods? Intake, Downpipes, etc?

If you turned it off to map0 its odd they would have looked in the DME compartment unless something on your car flagged?

Gotta agree on that one. They are just noting what they see when they look at the car. I don't think you can expect them to replace turbos under the extended warranty when you've put the JB4 before that warranty expires. Its a gamble putting a tune on and expecting warranty not to get voided. I'm genuinely sorry to hear that they found it but you gotta think that there was a chance it would happen.

Another one bites the dust... I wouldn't have towed it to BMW in the first place. Just my 2 cents.
Even with the tuner removed, don't you have to clear codes so BMW doesn't see it was previously tuned?

I honestly think they check all 335's that look to be owned by enthusiasts. It is such a common mod and easy to look for that I bet they just check it out as a matter of course.

I did turn to map 0 and deleted codes via the 1/2 steering wheel control settings. DCI was removed as well as catless AR DPs

Ok but if the VIN is not flagged then if the tune is removed and the codes are cleared wouldn't I be able to have them do it? I read somewhere on here that they do not look at the service histories???

[Sambonjo]

Is your VIN not on the service record? I can't imagine they would go through the hassle of checking your DME compartment and finding the tune, only to forget about it when performing potential warranty work. I know I know.....not what you want to hear

[csu87]

Just means you now have to get better turbo when yours fail. And since you had them DIAGNOSE what your issue was, of course they are going to go through everything to figure it out

[ferocity02]

If you cleared codes then they could probably see that your monitors weren't ready (or perhaps see that you had just cleared them, I'm not sure if it stores that kind of information) and looked further since it *could* have been related to your computer. Don't blame them for doing what you asked, a diagnosis.

A diagnosis is one thing. Flagging the vehicle is a totally other thing. You have to go out of your way to flag a vehicle. And why would you do so when the customer is paying out of pocket. Literally, your only intention thereafter is to deny any possible future unforeseen repairs. This is a malicious intent as there were no indications of warranty or "free" work. So let's try and not protect the multi-millionare dealer...k?

Yea, it seems like they made note that his car had aftermarket mods in case he comes back for future problems.

If you are asking why did they look for a tune it's likely because it's common on these vehicles and a common thing to push blame on. Since you asked them to diagnosis the issue with the injectors the first thing any mechanic is going to do is find something that could cause the issue. Keep in mind, I'm not defending this practice but it is common practice.

I'd suggest using a different dealer from now on and naturally ensuring all things are removed from the vehicle. I personally keep a small tool box in my car to remove things like the tune.

From the dealers perspective they made the note to CYA (Cover your @$$)...in this case, cover their's.

Don't really have to go too far out of the way. They aren't trying to screw you over, they are trying to keep you from screwing them. So what if they are a million, billion or trillion dollar dealer; they still have to run a profitable business. They don't make money by just fixing every ones car for free.

Also, can you prove that the jb4 didn't cause failure of the injectors? No, so that's why it's noted.

I'm not defending the dealer. It sucks that they found your JB4, but that's how they operate. Did the JB4 cause the issue? Probably not, but they noted it anyways in case you go back to get free work, such as the turbos. If the JB4 was installed you should have had it fixed somewhere else, especially if you're paying out of pocket.

When I was at my BMW dealer every single tech was interested in what mods were done to my car, they aren't stupid.

It's not hard to hop in the car and push both buttons on the steering wheel down and see what happens...

[smitty513]

The dealer is just covering their ass. If they refused to perform the repair because of it, then I'd be worried. As stupid as it sounds, there's always people out to milk free work from dealers.

OP, PM me

Exactly this, it's such a quick thing to press both buttons I bet it's a common thing to check for some dealers who care about all that.
