Wow! thanks so much for all the info and opinions, it has been really helpful.
I understand that there can be a problem with an oil cooler seal on the V6 diesel, was this issue rectified after a certain year/VIN? Or is it only rectified by the replacement seal?
Whilst I don’t know the answer to that, it’s a common repair and budget £700-1200 to have it done. I wouldn’t let this be a worry in any way on a tried and tested v6 engine that’s been standing the test of time. You can easily spend more than that chasing repeat niggles and failures on other models and marques regularly!
