Captains Log - Suplemental.
Car in with the dealer today and the alignment was checked. Front toe found out of tolerance and adjusted.
Now running true. Feels more like the previous one I had.
As noted it seems there is a new crew on the line setting (or rather miss-setting) the steering geometry.
Worth the check.

Good you got yours sorted Hugh, as you say, seems a little too common, but at least its easily sorted.

Ady - Any news on yours after them having it for the day ? ON THE WAY: BMW F21 M140i

I didn't ask if it was out when i picked mine up because all the service crew had finished before i picked it up, mine didn't pull to one side it was straight as a die, my problem was that the steering wheel was off centre by about an inch when steering straight, they tried to straighten it via the steering rack but there wasn't enough adjustment available there to put it straight So they gave it a 4 wheel alignment, still not 100% but as near as dam it.

Well gents I'm just back from putting another 250 miles on the clock in mixed roads in the west of Scotland. Oban to be exact. I have to say the steering is much improved. feels more neutral and evenly loaded right and left when cornering. I've no idea what the correct technical terms are but I hope you know what i mean.
For interest the work was done under warranty by Parks Land Rover. Don’t know what machine they used but I got a print out.
Very happy.
Thanks for the support and advice.
