Have you tried disconnecting the MAF unit yet

Takes ten seconds (once the bonnet is open!)
Costs nothing

Disconnect it, go for a drive and see what happens

lt's also a very easy part to change if it does turn out to be defective, takes about five minutes
I will try it but the last time I started the engine there was no delay.
 
I did and it didn't make a difference to the delay I am experiencing on start up. It doesn't cause me any issues and has happily been like it for the last 18months so I plan on ignoring it and continuing as I have been.
I did this until it got so bad it was more or less dangerous.
On advice from on here I checked live data, and it turned out to be the IAT sensor.
Relaced with a new Bosch one.
Problem solved.

And cleaning it did no good at all!
 
i have a 2003 disco 2 td5 with the same symptoms Filters all changed still a problem until i disconnected the sensors Can this do damage or is there something i am missing i have cleaned the sensors with a compressor and no change. The car just stops with the engine still running and after I switch off and on again it works HELP

Cleaning a sensor that is not working properly may well not fix it.
Live data should show which ones are not working properly and allow you to replace them.
