F8 CEL - P155D

I’ve been getting this CEL intermittently “P15DD” is the code. The car is normal with no hiccups in power when it comes on although the very first time a few weeks ago when it came on the car wouldn’t go past 4K RPMs.

It’s completely random in timing and I’m stumped as to what specifically the code is for as there isn’t any information on it online. Are any of you F chatters familiar with this specific code?

 

Novitec exhaust / spacers / sport springs.

 

Used the AP200 but also the shop that did the install had a fancy scanner and both results yielded same code. It's apparently a wheel speed sensor. I'm getting it checked out Thursday. I'll keep you posted.

 

To add to this likely being the wheel speed sensor I was also on 2 separate occasions getting a TPMS error indicator which I suspect is related to this CEL.

 

Spacers have nothing to do with a wheel speed sensor. The TPMS error was coming and going prior to spacers being put on and my service advisor also stated spacers likely have no correlation. It’s getting checked out now and I’ll circle back with update once taken care of.

 

Sorry didn't mean to come across the wrong way

 

O2 sensor related. Shop that did the Novitec install is checking it out Wednesday.

 

I don't think the sensor itself is bad, shop mentioned checking out the OPF connections. I suspect the sensor is looking for GPF related settings which aren't present. I agree it is unfortunate the lengths we have to do aftermarket mods just get the car to sound decent. It's perfect otherwise but the OEM exhaust is way too quiet.

 

Turns out there was a kinked hose that was connected to Novitec exhaust. Shop that did install fixed and car feels and sounds insane now. Did probably a 100 miles on it and it's been flawless.
