Hi,
After searching many forums I thought I'd try my luck here as you seem a helpful bunch! After a couple weeks of owning my Jag XF 2.7D (2008), I got the dreaded warning on the Dashboard: "DSC not available - Restricted Performance", with the "DSC" light on, followed by the yellow Check Engine light. After some research it seems that the Battery might be the issue, so I got this swapped out for a brand new one. Unfortunately this didn't fix the problem as the engine light was still on, and the DSC light came back on after driving a few miles. Bought a cheap ODB2 reader from Amazon (they're great - it was delivered next day!) and the only code that came up was P140A, which I researched to be a problem with the EGR Valve. Although since it is a cheap OBD2 reader - I suppose there could be other codes just not showing up.
I am by no means a mechanic (or even a good DIYer) but I am willing to give anything reasonable a try. What are your thoughts on fixing this (aside from taking it to the local Jag Indy which I am thinking of doing anyway).
Is it worth trying to clean the EGR sensor which I read somewhere else? Also read that cleaning the MAF might help? Appreciate your thoughts all.
Thanks
