Finally got it all back together, leaked coolant at the back, but nipping up the top egr bolt sorted that.
Code remained, and would not delete.
Bit of research and did a Lambda and 'HFM' reset with the Artidiag. That reset the values and cleared the code, taking it out of limp.
best part of an hour test drive done.
Driving like a new car! smoother than its been in a long time, no hesitation, no whoosh air leak sound.
Seems watertight, but will monitor for a week before I reattach the undertrays.
Re-checked codes, all good, DPF regen mush have happened on the test too as down to 10% again now.
Fingers crossed it remains all good. VERY glad that job is done. Would have been very expensive in a garage and one hell of an acheivement for me getting it done.
