m5q8 · 10-14-2015, 03:33 PM

hi i have 2008 ess supercharge m3 e92, the car was running just fine till the shop install a custom exhaust after that the shop try to jump my car to start it up with a 24v jumper by mistake. so the cable turn to be red after that the car does not run good first some sensor show up and i change them but still the car does not run good no code is showing
does that 24v screw something
i really need help
thank you

were you present the entire time they installed the exhaust? that sounds absolutely horrible and i'm surprised you are not displaying codes.

yes it is

Is that the bov opening and closing that I am seeing? Been out of turbos for a decade so I'm not familiar with that specific bov but they certainly aren't supposed to open and close rapidly like that, if that is what I'm seeing. Hard to get a close look on the phone.

someone had a similar knocking noise that was vacum line under the manifold/connected to bypass valve...research this forum and see if it pops up, he even posted a couple of videos so we could hear the sound. to be honest, your knock sounds pretty bad. how that came about from changing the exhaust is pretty questionable, that is why i asked if you were there during the install.

hly shit that's horrible, what happened?

Weyne Masters · 10-16-2015, 11:50 AM

i doesn’t make sense,PISTONS?

its better your looking for another shop and second opinion!!!

Doc Oc · 10-16-2015, 12:17 PM

That's terrible news....and suspect. If it was running just fine when you brought it to them and then running like this when you got it back it sounds like the shop did this. And a week to do the exhaust? Wtf? Sounds like someone had a week of fun at your expense. Did you record the mileage?

it sounds like they had some fun with it, i hope you know how many miles were before and after. This is completely not normal for an exhaust

Helmsman · 10-16-2015, 12:30 PM

Totally agree with Doc, I'd investigate this in freaking detail with the shop. I hope you snapped a pic of the mileage, if not I'd still find ways to go to the bottom on what have happend during the week they had the car mate.

Also whats up with the 24V jump start? If you mean they used 24V supply on the 12V system, I'd expect front end electronics could have burned. And what garage is doing that..?!

Good luck!

modkrazy · 10-16-2015, 02:58 PM

Why did they need to jump start the car? And a week to fit an exhaust?

Please tell me you recorded the mileage!

wheelpro · 10-22-2015, 07:32 AM

i feel you can found miss fire
please read car first and tell me smooth running in which cylender you
and please clear fult and read again

well one of the cylinder is not firing eventhough i change the spark plugs and coil

Tom@AUTOcouture · 10-24-2015, 08:16 AM

OP, A few things, and feel free to reach out to me via email or have the shop who installed the kit do as well ;Tom@autocouturemotoring.com or PM directly here. After personally installing 128 new and used ess vtx e9x kits I can honestly say that all E9x vehicles "can handle" a supercharger as long as there isn't under lying issues with the car.
-Was leak down and compression performed before supercharging? or after the car starting running as it is now?
-What type of mileage are you at now, pre/post drop off
-Have you had a recent oil sample done
-What type of exhaust was installed, i.e. something that is valvetronic in nature like an innotech?
-Who tuned the car ?

That "panting" condition you are witnessing at the BOV is a very odd vacuum signal. It could be easily be caused by a piston that has failed, but it is difficult to condemn an individual part failure like that without some in depth diag as apposed to bad vacuum hookup or for instance an idle actuator that is failing. The idle in conjunction with that symptom does not sound good but it very could be something valvetrain related as well. You mentioned that one cylinder isn't firing even though you changed the plug and coil. Is this cylinder getting spark ? Changing parts is a good way to sort out if you have an individual small part failure, but wont help to determine if those pieces are being told to fire from the DME. As you have located the cylinder that is not doing what it is designed to, measure the signal at the harness, and perform leak down and compression on that cylinder in addition to as many others as you can easily reach.

Please let me know how you make out and if there's any way I can assist remotely

Best of luck
