The D5 'only' has 170bhp and to be fair Doggy there's quite a bit of unrest regarding the D5 amongst some of my new, understanding, forum friends. They say it has somewhat of a drink problem and likes to fill up it's own sump with Diesel

the recommended fix by the dealer is to drain some of the 'mixture' out of the sump and run around just-above-minimum on the dippy
Apparently the FAP programme over-injects or something and you end up with fuel being dumped and somehow making it into the sump. Running around on minimum is an extra safeguard just in case the FAP programme fix don't work
The smoke-screen was probably down to the way under-takers drive usually - was probably out being tested by a garage or something?
I bet you've surprised a few people like this now with all your new torques, opening up big gaps behind you
