Check engine light E320 95
I just got a check engine light come on. Pull the fuse box cover and found fuse number 7 blown. Replaced the fuse but still has the engine ligh come on. Check the malfunction indication code in the diagnotic box near the battery and found Code 5 (Exhaust gas recirculation inoperative) and Code 21 (Purge switchover valve, open/short circuit). Where are the exhaust gas recirculation valve and purge switchover valve. Can I fix it or do I have to bring the car to a MB mechanic. Any suggestion is appreciated.
