Hey guys,

I'm definitely interested in taking that next step from a tune, X-pipe, filter only car to the next level and get LTH. My biggest concern is that I have a year left on my warranty and I'd hate to have something happen with the motor and it immediate be blamed on my LTH's. My question is has there been any documented cases of owners getting torched on a motor warranty claim because of their headers? I know these motors are relatively bullet proof, so I wouldn't expect there to be any issues. Any chance they could blame tranny problems on them as a result of the increased HP/TQ from the mods?

Just looking for some peace of mind (if there is any to be had).

Thanks!

LTH's will void warranty. However, I would assume if you build a solid relationship with your SA he/she might work something out if warranty problems arise.

Your drivetrain warranty was voided when you tuned it.

OrientBlue3

Right, but I can at least easily return it back to stock should I have any problems. With headers, it's not to easy.

I guess I was just curious if anyone can recount any stories that occured where someone actually lost their warranty or were denied a warranty claim as a result. I know things can go wrong, but have they with anyone? It doesn't seem like those stories ever get posted or get out if it does happen. I was just curious if there were any horror stories.

Was the ECU opened when it was tuned?

If the ECU was cracked to tune it they will know. I dont believe these flash tuners are undetectable either to be honest but time will tell.

I recall a few people on here having warranty claims denied due to headers being on the car. I cant recall the names but if you did a search I am sure you can find it.

their SAs must be jerks

warranty claims for what though? seems like all of the drivetrain "uphill" of the headers should be covered

propain

SA's are powerless. If you blow your tranny a MB rep will want to know why. They visit the MB shops before these claims are pushed through. The rep look for everything. Tunes, Exhaust. Anything aftermarket they can blame it on to avoid paying they will. If you wanna play you gotta be willing to pay.

I recall some guy having issues with misfires I believe.

I did a quick search. This is one that I remember... https://mbworld.org/forums/c63-amg-w204/402110-terminal-miss-fire-issue-again-2.html

My dealership know's about my LTH and ECU mod, and didn't say anything about voiding the warranty. Even I told them not to reflash my ECU because I tuned it, and they say nothing.

I think it varies from dealer to dealer.

What warranty work was it in for?

propain

Thats the magic question...


Sure, they dont care until you blow the motor. Then when the MB rep tells the dealership "No, we are not going to give you the parts for free" then you will see them change their tune.

My SA told me warranty will be void once the primary cats are remove. I don't seems to have problem with tune and 2nd cat delete so far with my SA.

OrientBlue3

I'm aware that LTH will void the warranty. I know that. My question all along has been has there been anyone with any issues the motor or tranny as a result of having them installed? Obviously if you blow your motor or tranny with LTH or any other mods like a tune, they will blame it on that and void your warranty. It is whether or not there have been any documented cases that I would like to know about. Or are LTH's such a bulletproof mod that if installed properly, no one has had any issues with them causing any problems?

propain

A bad tune will blow your motor much quicker than LTH's will.

To answer your question though, the C63 is pretty much bullet proof with mods up to that level. If you track it you might run into diff problems down the road depending on how hard you try to launch it.

I wonder how much gain these headers give above just removing the cats and putting in straight pipes and tune for that. The restriction is the primaries. Thats for sure.

i'm glad my car is OEM

I believe you

I took my car for the regular 10K checkup. They did mentioned earlier in the report that the aftermarket exhaust could be fire hazard due to overheating. No action from them so far.

My mod is MBH LT headers+High Flow Cats+Mid Pipes
the rest is OEM.

Sincity

WTF?

_timothy

are you WTFing at their assessment of a potential fire hazard?

jacob502

Tune+headers+catless pipes+intake+supercharger+lightweight rotors

And no problem with warranty

I believe that the OP was more interested in answers from US members. It doesn't really matter that you had no issues with your warranty since it's not the same rules in very country

Cool

So you are the only OEM C63 AMG with Carbon fiber Hood

jacob502

I believe my post was intended for the OP, who didn't clarify answers from US members only!

No one asked for your useless and worthless opinion!
