Hi Darren what sysptoms are you getting that caused you to have the codes read?? Current 2007 TDV8 Vogue Buckingham Blue

Intermitant judder at low engine revs when partially warm, was actually having gearbox checked and the guy kindly offered a diagnostic check FOC.

The judder may not be related to the transmission, particularly if you feel the judder when stationary.

Regardless I would be accessing the EGRs for a look, or possibly putting borescope in from the manifold side. I don't know if the EGR cooler would prevent you seeing the valve. ______________________________

Best place to start would be with the egr valve live data to make sure they are both opening and closing together. This could just be a sensor throwing a fault due to a small electrical issue and be nothing! Have you had any symptoms relating to failing egr valves such as engine management light/system faults ont he dash?? Cant see an egr fault causing a judder though! Current 2007 TDV8 Vogue Buckingham Blue

No system lights or dash warnings.

Both egr valves replaced and new glowplugs, runs like a dream now.
