Haha I thought that silly me ...lol

Where do you put them ? On the fuel rail pressure sensor ?

I went to land rover dealers today they say it's a device used to save fuel you put it on the fuel sensor and it sends a message to th ecu to run more efficient to save fuel or something like that

Can you see it tom

This is it tom

I have Tom there is just a small pc board in the box

Thanks for the reply tom1979 I just don' t no it wasn' coupled up to anything just cable tied to the battery leads and the box dropped down the side of the battery and the lead was just dropped in the engine bay

It look's to me like something that goes onto a sensor ?

Lol I wish it was

Thank you for letting me join your forum my name is mark and i have just purchased a 2004 TD4 HSE iv never had a land rover before but since iv had it im well impressed with it i have a small issue with black smoke and running a bit rich but im sure when a friend put a test on it it turns out...
