Question
Hi. I have the diagnostic codes E.E48, E52 what do they mean? i m also worried about the oil light it goes on and off all the time even when I just renewed the oil.
Last Q. The car also shakes at the back untill about 45 miles. do i need to tight my shocks or is it something else?....

Already lots of thanks

Answer
EE48 means that you have a fault in your EXHAUST GAS RECIRCULATION SYSTEM (EGR). You will need several pictures of component locations as well as simple test directives and since this website only allows one picture and you need several, Please E-mail: onlineautohelp@msn.com
