Hi. I've been having a problem with my S55 for a couple of weeks. When i'm slowing down to take a corner or to stop at lights my car will randomly shut down. Its a bit worrying especially when im taking a corner because the steering feels like it locked up. It doesn't happen all the time, just randomly but only when i'm on the brakes. After it shuts down I just put it into park and restart the car it works fine. I've searched everywhere and all i've found is a problem with the CPS however i dont think this is the problem as i can start it immdiately after it shuts down and i have been keeping an eye on the engine temp and it happens wether it is cool or running hot. I have noticed that every now and then when i come to a stop the engine rumbles a bit once its changed back to first gear but this only happens for a few seconds then idles normally. Any help would be really appreciated. Thanks in advance.

Check for vacuum leaks and also the EGR valve, if it is sticking it will cause that problem also.

^ this.

issues are going to cause idle problems that throw a code.
Same with the EGR you would have a P04** range code.
The cps often throws no code and operating temp or lower can cause the symptoms you have.
For 42 bucks and 15 minutes of your time,why not r/r it and rule it out.

any chance you have a scanner hook up and read out DTC?

crankshaft sensor fail could make the vehicle stall at times..

No unfortunately i dont have a scanner. Can anyone recommend a good one and where to get it?
