Help please I recently bought an 07 335i it was running great then the battery died had to get it towed to a shop. New battery in and now the car is idles rough between 1000 and 1400 RPM. There's no throttle response when I step on the gas pedal.

I was told it was onlimp mode but the mechanic had no idea how to fix it. It has 4 code p164c, P1417,P1632 and P0221.

I would advise you to get your hands on a BMW-capable scanner rather than that generic crap your "mechanic" is using, but since you had the car towed to a shop to replace the battery, I'm guessing you're not interested in DIYing this. So...
Find a better mechanic.

The Codes, AND the symptoms of "limp mode" indicate a problem with (1) the Accelerator Pedal Module, and (2) the Throttle Valve. A shop with INPA or ISTA can test those two components rather quickly, and you should NOT just throw parts at it without such testing. Could be a wiring fault rather than a bad component, or even a power supply or adaptation issue, hence the need for proper diagnostic testing by a shop with the proper software.

Here are the code DEFINITIONS for each of those codes, per Bentley:
P0221 | 2CF7 | Throttle/Pedal Position Sensor/Switch '8' Circuit Range/Performance
P164C | 2D1D | Pedal Position Sensor Potentiometer Supply Channel 1 Electrical
P1417 | 2D06 | Throttle Control Incorrect Air Supply
P1632 | 2CFB | Throttle Valve Adaptation Conditions Not Met

Here are the circuit diagrams for the Accelerator Pedal Module (B10) and Throttle Valve (Y63900):

Please let us know what you find,

Happened to me on my 2006 325i. You need to do a throttle adaptation- key in ignition; push start button once (without foot on brake so car doesn't start); push throttle pedal to the floor for about 30 seconds. While still holding throttle pedal down, push start button one more time; release throttle pedal. That's it. Start the car and it'll work fine. It sounds ridiculous, but it is the procedure.

Have a 2007 BMW 335 and the gas pedal would not work and it would rev up and down by its self.
Thanks Ohiobikes, this process worked on mine.
