my 313cdi 2005 did the same, im reading from the repair sheet the mechanic left, repair loom at n/s/f engine mount, carry out star diagnostic. charged me £200 a mobile bloke called dean 07974975039, he lives in london but came out to me in birmingham and also cut and coded me a new sprinter key in that price. it says www.williamsdiesels.com on his work sheet so you can look at his website. hope you get sorted mate
