I’m an idiot...

[hworang00]

I know will be slammed for this...but...

I was doing some work on my car and thought it would be a good time to update my tunes on the transmission and engine. I flashed the transmission to the BM3 CS tune without reading the instructions well (I have a 2015 M3 and the CS tune is for 2018+), and the next day drove for a few minutes and BOOM, transmission malfunction...whatever I’ll flash it when I stop...go to flash...failure...tried it again and failure...at this point I should’ve stopped and gotten a tender because my daily commute is short. Then the car started throwing all sorts of faults...transmission, EDC, pedestrian, etc. Now it looks like I basically killed my $1200 battery and when I have it towed to BMW they will tell me I need a new DME and ECU...I hate myself so much right now. I know I’m an idiot for not reading the instructions carefully...I just had to vent to some people who might’ve made the same mistake or can sympathize. I also know I’ll get a lot of people who will flame me for it...but

Please learn from my experiences. I’ve flashed many times before and didn’t think much of it...but put a tender on your car while you flash and read the small print...it’ll save you a lot of headache.

Can't PTF sort while your car is on a trickle charger ?

Their customer service is brilliant in my experience

+1 try this before downing a few thousand from your account.

[hworang00]

Hmmm I can try...

EDIT: just emailed them to try to get something set up

Sorry to hear that man . I just got a 2015 m4 and just done my first flash ever. Ur post gave me chills and I had to go back and check to make sure I did the gts for the trans.

Hang in there... you may get it resolved

[Mojoman]

I give you props for owning it and just putting it out there. Hopefully PTF or someone knowledgeable will be able to help you out.

We've all had projects or modifications go in this manner at some point or another. I'm sure no permanent damage is done and it will get sorted out. Just chock it up to a learning experience, my wife would always say to me "you're not a professional mechanic don't beat yourself up"

Contact kubax86 , he might be able to help.

A second Kubax86

Try fully charging your battery with a CTEK Lithium charger and re-flash. Definitely don't take it to the dealer and don't panic. You'll be fine.

It's a lithium battery, not the lead-acid kind of most cars, all it should need is to be charged back up.

Thanks guys! You guys are awesome...yeah it was definitely a learning experience. Serge from PTF got me hooked up for a remote session tomorrow. I'm not going to lie, the guys there are second to none, been talking to me nonstop through email since I contacted them and they usually get back to me in 30 minutes. Best customer service experience I've ever had!

Soooo what happened?

Haha, I linked up with Serge...the battery completely died...had it towed and BMW recovered the battery (YAY!) but said that my CPU overheated and fried...they linked the CPU/DME to Carbahn and they said it was not salvageable and then they linked up with BMW Germany and they said the same thing. They are saying that the transmission may also need to be replaced. I'm confused as to what to believe. I spoke with Serge and he said that he believes it can be fixed, but BMW keeps telling me it can't be and since the DME is out, if I asked to have it put back in and it's not salvageable, I would have to pay another $500 to have the shit taken back apart to replace the DME...so torn and confused...Need someone who has been in this position to chime in because the DME is 3800 and the labor for taking the DME back out of $500...

Both parties have been REALLY helpful. Kenneth at BMW Southpoint has been super willing to help, I just don't know if they are just looking at the codes or what...and Serge is being awesome too but he hasn't seen the car so I don't know if he actually knows if it's doable or not...I think I may have just gone too hard to try to fix it and I think I may have forked it up even more...sigh

Yeah it sucks...but it's my dumbass fault...I should've been more patient and not tried to flash back to back to back...especially once it failed...who knows...I'm hoping someone can give me some advice.
