I did a clutch-pack re-calibration of the 6-speed in my D4 trying to overcome a fault but which required a rebuild due to stator bush failure. I often reset adaptions with a diagnostic tool to get rid of the sluggish gear changes as most of the time I used the engine's torque which eventually resulted in the sluggish take-offs.Quote:

I don’t think this is relevant for your trans issue but worth noting anyway.Quote:

The shut-off valve sticking was a design issue, overcome with a re-design of the linkages for both the 3.0 and the 4.4. However the occasional clearing of any oil residue in the secondary turbo inlet tract is worthwhile.
Many thankyou's to everyone who has offered their opinion and thoughts re this problem. It is very much appreciated and if it happens again I'll try to note a few things and report back.Quote:

I have taken on board your interesting & knowledgeable comments re mothering the engine too much and in the interest of making the 2nd turbo work and reducing soot etc I promise to give it a bit more stick.
When you think about it, 3000 rpm is not a lot!
I replaced the brake light switch 26,000 klms ago early last year as a precautionary measure.
Invoices provided with the car show the battery was replaced in October 2017 which was roughly 78,000 klms ago, but I will get it checked. Thankyou for mentioning that.
Looking at the odometer yesterday I see its done 149,000; that last 3,000 crept up fast over past coupla months!
I am thinking the alternator may be getting close to needing replacement?
If we get away to the mainland this winter I'll replace it before leaving Tassy if you think it would be a good idea as it will have around 155,000 by June.
PS: Last week I once again (have driven it a few times) drove a friend's 24 month old LC200.
They are not a patch on a Disco. Just a glorified luxurious light truck in comparison!
Good process [emoji41]
Mine regularly sees the red end of the tacho.
The car won’t let you kill it, even in manual it will force a shift.
No, but some tend to commit suicide by letting their crank go....Quote:
