Hi, fellow Jag-lovers!
My daughter’s car again; the DSC warning comes on immediately when selecting Drive, and the message “restricted performance” is presented.
Any wisdom on this, anyone?
Kind regards,

From my understanding, there’s a myriad of things that could cause this. Have you used a scan tool to read the codes yet? That’s probably your best starting point. It could be a MAF issue, an EGR issue, MAP issue, a gearbox issue, or possibly something else less common.
Hi Brett(?)
I have scanned it but didn’t find any mention of DSC and didn’t see any logical connection to neither MAF nor EGR etc. I did get faults like:
That’s a lot! I had lots of errors earlier and cleaned the main ground at the gearbox, and most of them disappeared!
Any thoughts?

Just a shot in the dark, but how old is your battery?
It is new!

I wish I could help more, but with such a long list of faults, I’m not sure where to start. Maybe someone else will chime in who has had a similar experience.
Hi,
Time for an update on this issue; We cleared most of the fault codes and upon a visit to the Jaguar dealer it turns out we are left with one code;
P045C-00 Exhaust ga recirculation B Control Circuit Low
The EGR valve was taken out and thoroughly cleaned, the operation verified; opening and shutting with applied voltage; 5V and connected via the connector. Still the fault message displays (albeit this time a little delayed).
Has anybody been through all of this and found a solution? I need all the wisdom existing out there on this one!
Kind regards,
Bard
Hi,
I’m back with a new topic on this problem. I have concluded the EGRs have to be disabled, which brings the challenge of re-mapping [the ECU?] as this is a 2009 MY.
Has anyone been down this road, and what does it entail?
Best regards,
