Ok does anyone know if the exhaust temp should be the same temp coming out both the right and left of exhaust tips. I was working on something the other day and the car was running and i put my hand over the left side exhaust tip ( driver side ) and it was pretty cool and I could touch the exhaust tip and not have to worry about burning my fingers. Then went over to the left side exhaust tip ( pass. side ) and put my hand over the exhaust tip and it was hot and i couldn't touch the exhaust tip for more then a few sec. This was after I was driving for about an hour. So Im not sure if this should be like this or if there is a problem. I have just had problems with power on my MCS, so wanted to check with you guys first before i went to the dealer and if i needed to get a temp gun. Thanks

 

The pipe from the engine drops into the middle of the muffler, with an exit out each end. In the absence of any clever stuff inside, it seems like you should have flow out both sides. IMHO

What gamma said. From the turbo back it's basically a straight pipe with kitty's along the way then into a muffler with 2 exhaust ports.

If I were worried about exhaust temp I'd install a Pyrometer and tap the exhaust manifold for the sensor.

Then again, this isn't a turbo diesel pullin a 15K 5th wheel.

 

So it should have the same exhaust temp coming out both sides correct ( hot)? If so i think i have a problem.

 

I pulled out a multichannel thermocouple system and plugged it into the inverter I keep in my CM4 before driving home from work today.

At idle, the right exhaust time was at 88F and the left at 74F. Watching the exhaust with some condensation in it, the two outlets seemed to put out about the same flow. Revving up the engine, that continued with just more flow.

After a thirty-minute drive, the right was 163F and the left 120F

Who knows what to expect?

 

So maybe it is suppose to be two different temps. But that just doesn't make sence. one pipe going into a muffler and then two out and the temps would be diff who knows

 

So went to the dealer today, had to have a hesitation problem when accelerating, that i wanted them to look at and told my MA about the exhaust temp problem. She said that it may be some composite build up and she would have them look into it. So i was sitting there for about an hour and she came back and told me that there was some composite build up and that they will have to reboot the entire car, FML. I don’t know if that has to do with the exhaust temp or the hesitation problem, and of course they didn't have any minis to take so had to get an enterprise rent a car and go through all that crap. Keep you updated.

 

Well as i was writting this they called me and told me that that it had all updates and could not recreate the problem with hesiation but they can never recrate the problem so going to pick it up and the temp would equal it's self out after driving. Told them that i checked it after driving for an hour and the temps were still off, but they said that it was normal. I dont think so, so it means i will have to make a video and show that the temps are off after driving for a while pain in my ***.

 

my suggestion is that you make sure that the dealer notes your account exactly with what you are telling them. i hope you get this resolved soon and to your satisfaction. reading this forum scares me...it seems people generally love the concept of the mini but seems that testing, unfortunately, is done on consumers. i really wanted to get the turbo...but too many of the same issue kept me from doing so. even if half of the turbos have no issues, half still do and those aren't odds i can afford since this will be my commuting vehicle. that said, i could still have issues...and if i do...i will be heard...GLTA

 

Are the pipe lengths the same for each side? Is there any difference in parts underneath that could have more or less air flow over the exposed exhaust?

Not every car has the same amount of exhaust out each side. I remember recently reading on here someone had a BMW and the dual exhaust was noticeably dirtier on one side of the car than the other and it was deemed normal.

The inside of the muffler baffle could be favoring one side too. Not something I would worry about.




I also wouldn't worry about problems you don't have. If you have hesitation, then possibly. But if you don't have an N14 or N18 engine, don't worry about the issues that are associated with them. Some people are getting tired of other complaining about how scared they are of cars they don't even own or how the forum makes them think their car is a piece of crap even if they haven't had issues.
I'm just saying, don't bother whining if you don't have anything to whine about. This isn't even meant in a mean way so please don't take it that way, but it adds nothing to this forum to post up in every thread how a turbo engine scare you and can be crap...we have plenty of those already.

 

I haven't been whining about anything just telling what has happen to me and my mcs. The hesitation has happened a couple of times i mean, when your going to hit the gas and the car falls on it's face, i mean come on there has to be a problem somewhere in the system. Just like the three other major problems i had with misfiring and power lost. I'm not complaining about anything I'm just staing facts that have happened. I dont think the car is a piece of crap, just bad luck but if the same problems are happening with others, then there must be a problem. Oh and the pipes look to me the same size cant tell what's inside the muffler thow. Both have the same amount of exhaust composit on both sides

 

Yeah she noted my acct and i have the paperwork as well. They always want to recreate the problem but it never happens lol so just got to see if it does it again. I dont think it's a turbo problem i think they all have the problems turbo non-turbo you never know.

 

I wasn't referring to you. If my car had a hesitation I would issues too being that new. That does truly suck and sounds like you may not be the first on here with that issue on the CMS or CM4. Sorry if I was confusing.

I was referring to others who just constantly complain about how crappy a MINI is or how turbos fail or HPFP fail, etc.

 

hi mavryk,
see yetti is referring to me...he doesnt have the guts to call me out but i will call him out. he has been critical of me before on another thread and he was absolutely wrong then and absolutely wrong now. absolutely wrong then when he tried to defend someone laughing at someone elses issue...when i was sympathetic. yetti then went away because the original poster stated that this was no laughing matter. to clarify, i never ever said anything was a piece of crap. (check all my posts) yetti is overly sensitive...perhaps that time of the month for him or her? i dont know what his problem is but he is becoming a stalker of mine. last time i checked this is a free country to discuss anything and i will continue to voice my opinion freely. like someone else started a thread "the good the bad and the ugly" perhaps you yetti should start one, "the good the good and the good". forums are for discussing the good bad and ugly...so if you do not believe in this premise...yetti...then find another forum or dont read any posters that have issues or grow a pair and stop "whining".

 

Going back to the original problem and its relation to exhaust temps:

Hesitiation is a problem. It should not happen and it sounds like the dealer is struggling to find it. Hopefully the car will throw a fault code if it happens again and then there will be a trail for them to follow. Since it seems very sporadic they may have a hard time recreating. That can get furstrating.

On the exhaust temp. It may not be a big deal. Ghamma measured his temp and posted this: "After a thirty-minute drive, the right was 163F and the left 120F." That's really going the extra mile and yours may be normal.

 

That might have been me. My car before the MINI was a 335i and the right exhaust was always dirtier than the left. Dealer said it was "operating as designed". I always looked at the exhaust tips of other 335's and they were all that way. I seem to be getting equal soot on my MCS tips, but I haven't tested the temps from each one.

 

You may very well have been the one I remember reading about this on. It seems a bit odd to me but if they deem it at normal and you have seen tons of others just like it...not effecting the car, then I wouldn't worry about it. That is all I was saying about the temperature difference.

 

Too personal to leave alone, lol. While I may or may not have been referring to you, as you are not the only near troll that seems to post in every negative thread, I left it open ended as it is against forum rules here to personally attack others. I did not quote you or others (referring to the use of the word crap), just stated it gets annoying to consistently see these negative threads and then have more people chime in that haven't even had those problems or even others have gotten rid of their MINI but continue to lurk on here to post about the reliability and build quality of a MINI.

I am no stalker, I just read the current posts and it seems like every semi-negative thread has you posting in it these past 2 weeks about how you are glad you got a non-S because of the problems. I was just complaining that you were not adding any significant value to the thread for the OP.

I am not looking for any sort of fight or continual banter on future threads but enough is enough. I have had issues with both of my MINIs, oddly enough much more on my justa than my S ($11k in 6 months for my R50 vs <$1500 in a year for my R56S), all under warranty luckily.

This is where the internet blows. If we were face to face, a <5 min conversation would be much more successful, most likely ending in an agreement to disagree. So sorry if we aren't communicating well, for the sake of the usefulness of this forum I will try to not post referring to a post of your in the future.

I wish things could be discussed easier than through the typed word. Please accept my apologies and maybe one day we can meet at MOTD and share a beer at the brew swap and not be so feisty.

I need to remember this myself. Yes I know its not nice to "developmentally slow" children, please do not take offense on this anyone.



OP, sorry for thread-jacking...now back to your regularly scheduled MINI "uniqueness" issue.
