Hi Brian
Welcome to the club.
I really like the BMW...the Patrol also.
I agree,
I believe this Patrol is going in to 'limp mode' when it is overboosting.
This occurs when driven hard in certain gear ranges.
This is fixable, and is common amongst many Patrol owners with the ZD30 engine.
I can though, understand your reasons for being cautious as you'll be dependent on the Patrol as soon as you have it.
The new price (£5000) for the vehicle is good considering its condition and mileage though.
There is a small group of Patrol owners on here, myself included.
If you decide to pass this one up, just spend time on here with any questions you may have, while searching for your Japanese Superbabe!
Everybody on here will help if they can!:thumb2
