Update
So managed to do a little bit more
Suspension error was a blown fuse in engine bay F3 , 5 x amp for ECU , suspension now fully working
As it hasn’t been used for 6 x months I took it for a drive round my local area , keeping the speed under 50mph as I thought then it would be less stress on the engine instead of just taking it down the motorway @70Mph
Got back most of the interior sill panels
2 x new bonnet struts , found using the small picks and rounded pliers ideal getting the old ones off
Re fitted both battery covers
Replaced as much of the engine bays electrical conduit
Engine cover insulation
Had the Autel handy so just plugged that in, found the bank 0 data and could see the figures were fluctuating a few % , but after the test drive and engine up to temperature it smoothed out
Don’t know if it was just me but the power came a lot smoother and quicker , at tick over the Rev counter now stays completely still with no fluctuating
I’m wondering because I’ve taken a lot of time ensuring all air inlet and intercooler leaks have now all gone if that’s contributed by the engine responsiveness being better
Don’t mind admitting am over the moon with the results , hope I never have to revisit the hoses/ pipes around the turbo area
Got a few things left to do
Passenger side plastic wheel arch trim
Small panels by the FBH exhaust
Door window glass trims
Get some fuel injector cleaner to run through the fuel tank
Also the drivers side master window switch is playing up again, unable to lower the front passenger window but works on its own controls
That’s was a challenge and a half trying to find the part number as see some are pre and post 2007 , 16 or 17 pin
So all in all I think some good progress so I’m getting there
Finally, I can’t even begin to say how grateful I am for the extremely kind help , million thanks from the bottom of my heart as I know I wouldn’t have been any where near , will update as I progress with the other bits
Know the rear outer sensor is faulty , got a new loom , other 2 x error codes have gone after resolving suspension issue
Few screen shots and data to go with this thread, plus I really hope this helps others
Thks again , plus am really pleased after all the work, plus think I’ve learnt quite abit along the way
