I did confirm, as I was in my UpRev software tonight, that the ECU part number looks to be changed.Ilya wrote:Actually, if I recall, something does change when I connect the cable and read it...it says "UpRev" somewhere, not sure if it's the part number or somewhere else. Will have to check.
Yes, as I bought mine used last year. 2012 M56X lease turn in with 52,000 miles.Kareem wrote:I was wondering if the recall would apply to owners of M56's who purchased used. In my case, I'm the 3rd owner.
Thanks for the Great Info!
Anything that is a recall is covered by the dealer. Not sure if all of those have been found to be actual recalls yet or not.dLat wrote:This is great info, I plan on buying a used one, but not from an official Infiniti dealer unfortunately. Would the repair costs for all of the:
- timing chain (ID: P6305)
o ITB11-047b (Bluetooth Sound Quality)
o ITB12-021B (for M37 ECU/TCU software but I seem to have some of the same lag and hesitation)
o ITB11-046a (Call Waiting Navigation Update)
o ITB12-010a/ITB15-017 (Fuel Rail Re-torque)
o ITB10-040 (Air/Fuel Ratio Sensor)
come out of my own pocket?
As far as I can tell it is for 2011-13 M56 models and probably the same year range of QX80. The 2014+ Q70 (with the 5.6 obviously) do not seem to be included...yet.lovemycarM35 wrote:I don't have the M56, but I'm curious is this only affecting certain VIN numbers on the 56? or is it everyone one on the road
It's based on VIN...they must have determined that a particular period of manufacturing is when the issue existed. On the QX56, it was also a whine when the car was running (long after the normal whine of the cold loop goes away).lovemycarM35 wrote:Yea I was just reading the post others are reporting after the repair, the startup noise is still there so that must be normal noise from that video. So how do you know the chain is bad on your car? is there a code at some point.
adeedpb wrote:Would a stretched chain cause any lapse in performance?
It seems my car has much more power and runs a lot smoother than it did before the recall work.
In my case, yes it will affect performance big time. My chain (B2 side) was stretched to the point where the transmission threw a P0024 exhaust valve timing code. I couldn't accelerate to pass anyone, but if I pressed the pedal slowly I could build up speed. Same issue at a stop light. If I tried to accelerate quickly, it would bog down.spirod wrote:adeedpb wrote:Would a stretched chain cause any lapse in performance?

I don't believe so. The dealer disconnects the battery while replacing the chains which may reset the ECU and transmission programming. This may be why you feel your car has more power.
I drive my car in sport and manual mode and find the car performing the same as before the chains were replaced. I was told the original chains were not stretched but I only have
27,000 km on the odometer.
Without knowing if any codes were in the system, it's hard to say. Limp mode is an all encompassing protection protocol of sorts and can happen for 100 different reasons.markmitchell2292 wrote:I have a 2012 M56x. Recently, it went into "limp mode".

No it definitely wasn't because of the ECU reset... I have reset the ECU when flashing new tunes numerous times and am very familiar with the feel of the car after a reset; plus I have already put a good 150 miles on it since the reset. Maybe its the HPS intake tubes :p (That was sarcasm)spirod wrote:adeedpb wrote:Would a stretched chain cause any lapse in performance?

Did the check engine light come on? What was the diagnostic trouble code they got from the car? This code will generally point you in the direction of the cause of your issue(s). It is most likely what made them look to the throttle body as well.markmitchell2292 wrote:I have a 2012 M56x. Recently, it went into "limp mode".

Different engine block. Different timing parts. Don't worry about it.lovemycarM35 wrote:That's crazy I hope this doesn't happen to the M37 I kinda worried
The M37 does not have enough HP to stretch the chains, don't worry.lovemycarM35 wrote:That's crazy I hope this doesn't happen to the M37 I kinda worried

I'll see myself out.
It wouldn't matter at our store, I can say that for sure.Ilya wrote:
New question Steve...will I get beef if I leave my HPS intake tubes installed when I bring it in or should I be on the safe side and put the stock intake stuff back before I drop it off? I plan to completely remove the UpRev map too.
I've done one with 22k. I have one I'm doing next week with 37k on it that's noisy.adeedpb wrote:Looks like the damage can even happen to a low mileage car...
Picked up my car today, according to the service log:
Timing chains were stretched and one oil jet was damaged.
I only have 38K on the odometer, I was pretty surprised to see damage had already taken place. I definitely recommend everyone get this done right away.
