Hi,

We have a 2019 RRS TDV6, with fault codes P2279-6 intake air leak mechanical fault and P049B Exhaust gas recirculation (EGR) B - insufficient flow detected.
It had a swollen O ring between the air flow meter and the throttle body (which was blowing oil out), this was done and no different, DPF was pretty full, now been regenerated and soot content is now low.

It has had a "chattering" EGR valve for a long while, checked all vacuum pipes, seemed ok, changed pressure sensor LR076235 which got vacuum system working again (still chattering) and it started driving much better.

But now drops into limp home mode under the slightest load.

All input very welcome,

Regards,

Roy
