A good 'result' - but bizarre 🤣 Paul,

Steering back to being 'ok' today (not perfect but not terrible just manageable)

Okay so this RR is doing something different to all the others.

Tyre presures are lower when cold than when hot. |

I agree Pawl, I also agree Graeme.

Cold makes the tyre compound stiffer which may cancel out or even over compensate for any pressure loss. Also I have found higher than stock pressures give me a better ride quality which maybe has to do with how tyre compliance interacts with velocity signals sent to the CVD ECU? Your drivability issues also sound like a leaky EGR valve and in cold weather the EGR valve opens less as I found recently when my average regen interval went from 80 to 560 miles and the EGR valve never opened more than 10-20 %.Worth checking the EGR error value and the difference between comanded and actual opening values . Mine seems to have a 4-5% error i.e the actual position is higher than the commanded. I'm now seriously toying with an EGR software delete. 2012 TDV8 Vogue (L322) |

Interesting information Jaygee, I'm sure the tyre and it's pressure do effect the way the CVD module will control your suspension.

I was assuming it was a late L322. No idea why the suspension should be stiffening up on a non CVD car or why you are getting drivability issues with blanked EGR valves other than the usual air leaks which cause similar issues. If you have a GAP IID tool it's worth checking the air intake temps and charge intake temps to see if they are 'plausible' Both MAF's I assume have IAT 's on them and should read the same and lower than the charge intake IAT. 2012 TDV8 Vogue (L322) |

Probably because I've made all these complaints about 2 later L322s before Jaygee

Maybe worth doing the EGR software delete anyway through the GAP tool add-on as it's a wise move anyway to protect the turbo's 2012 TDV8 Vogue (L322) |

It's something I plan to do Jaygee but sadly I haven't an IID tool at the moment.

A thought that crossed my mind, when I did the power steering fluid replacement I used Smith and Allan cold climate fluid.

Okay so this just gets more and more confusing.
