Have had my new 09' sedan for about a week and half now and have been reading about tuning ect... Seems like the steps to perfection start with a tune, followed by the parts needed to run a stage 2. Will intake, FMIC, exhaust void any off the recognized BMW warranties related to the lawsuits around the Fuel Pump & Wastegate?

[techwhiz]

Intake/Exhaust probably not.
FMIC maybe.
Tune for wastegates, probably.

None of these affect the HPFP.

If the dealer wants to they can. Just remove them before servicing and warranty and you will have a better chance of them completing the work.

I only plan on removing my DPs for turbo/wastegate work. Otherwise ill leave it on.

This post should be a sticky for anyone with a "will mod x void my warranty" question. There's nothing else that needs to be said IMO.

[Greatdane84]

Thanks everyone for the replies.

135pats I agree.

Had to ask with the extensive experience on these boards with tuned n54, 55's and the 2 bmw addressed extended warranty problems. Figured someone has taken their car in and had BMW give them a hard time.

Just had this convo with my SA. He said as long as they cant relate the problem you are attempting to service to the Aftermarket part then your fine. If they do find that the part caused or possibly cause the problem that only that area of the car is voided.

Ex: downpipes and 02 sensors going. 02 sensors would not be covered.

From my dealer point of view :
Intake, exhaust are no biggie and they don't care at all
FMIC is a grey zone and shouldnt affect but if its a boost leak or something they might or might not cover it
Downpipe, chargepipe with BOV are NO NO on the warranty
Tune is not a problem unless it caused the issue (but I still remove my cobb everytime).

Speak with your dealer its the best way to know all dealer are different. You definetely dont want your vin to be blacklisted.

Realistically the Dealer can void it for what ever they want. The words "OR POSSIBLY CAUSED THE PROBLEM" means they can make up whatever story to not have it covered and or void your warranty. If I was you and you ran into a big issue just make sure you convert it back to stock, just to be safe. If its for maintenance related issues you shouldnt have anything to worry about. Just set your tune to "stock map" which most tunes have. For example the JB4 stock map is map 0. Hope this helps

[Greatdane84]

Yeah, I'm getting the Cobb, then intakes, then FMIC so I think I'll be safe for now.

I had my wastgates replaced recently at 81k miles under warranty. I uninstalled my cobb tune as a precaution. I called my SA and asked if an DCIntake, and (forge) DV's would be a problem, or if i should take them off, and he said its not related to this issue so it's fine to leave them on. Realistically, they can choose to make up anything if they don't want to work with you, so as a precaution, remove your tune for sure, and anything else that isn't a PIA, unless your cool with your SA.

Wow you just made it to the Wastegate mileage warranty of 82,000 if you didn't have any other warranties! Congrats

haha yeah, thanks! I figured it wouldn't hurt to call them up and ask, and frankly, the dealers usually need all the service work they can get, even if BMW is paying them for it, so it's in their best interest to try and get it approved. Just make sure your very, very, specific about what needs to be done to reproduce your issue reliably.

Still, some can and/or may choose to deny a job.

This is just other words for no matter what modifications you do, the warranty will most likely be voided. Just finished dealing with the same scenario when the modifications I had okay'd with a service adviser voided my warranty.

[napeHbNYC]

Sorry to hear that. But can I ask for more details, if you do not mind?

[ken1137]

Jeez! they cannot void your warranty unless the aftermarket part was the root cause of the failure. Yes, dealers will say this hoping you walk away. FYI...I leave mine on when I go to the dealer. GL

What were signs that you needed new wastegates? Did they start to make noise? What about the turbos, the warranty expires at 82k also. Too bad you could have them cover those as well.
