Are you sure you cleared the code properly? To clear the codes, you must follow these steps;

Press the blinker push button for 2 - 4 seconds. The fault code will reappear.
Wait 3 seconds after the last blink, then press the blinker push button for 6 - 8 seconds.
Repeat for each fault code. Each code must be erased individually.
You MUST begin to clear the fault code within 20 seconds of of reading the fault. After 20 seconds, the fault will not clear unless you begin the process over again.

If the built-in LED is giving you 5 flashes, this is the code for Faulty Exhaust Gas Recirculation. As Arthur says, use the Search feature to find all sorts of useful stuff on EGR faults.
