I think this is a very common issue on catless or piggyback tuned M5's. If you search the forums I think you will find a few threads on the issue. There even is a poll on drivetrain malfunction here

It's not just a catless problem. It happened in a similar way with my catted downpipes too (no tune).

That was due to you missing your last country run. We had 18 cars

F12M6MD · 01-18-2015, 06:45 PM

Dang boots!

Sorry I missed that one! Next time for sure. I have the Dinan Stage 1 now and will be reinstalling the Meisterschaft so we'll have that to play with.

boots · 01-19-2015, 08:58 PM

Congrats! Spinnys car runs good w it. Can't wait to c how yours runs.

Car slows down we looked error code it says high turbo pressure anyway i just installed pp-performance stage 1 software everthing is ok right now

Don't gave 2nd thoughts. I've ran my car w approximately 30k miles w Catless dp. And only got approximately 7 dtmal. Don't let that stop you.

My friend has 2014 m5 mine is 2012 he installed catless downpipes and car only gave check engine error it doesnt cut the power.

It will happen eventually. Missing catalyst creates issues with air/fuel ratios at certain rpm's under certain load. This causes a drivetrain malfunction, which translates into a CEL or a code. Some of us here will be selling BMS piggy backs along with CAN tools that will solve your issue. Since CAN tools are extinct they will probably go for a pretty high price. I know Boots is taking tabs of gold for his.

Every car will have issues with no cats and no tuning.

You will get occasional limp modes, but a simple restart will recover it.
With the ECU flash available now you will be able to ditch that and be worry free. We are working on a group buy, pm me for details.

6spdterror · 01-21-2015, 04:47 PM

Group buy for the AMS Tune?
