The adblue is the gauge next to it so it's full most of the way

There a huge lack of power, it struggles to hit 25 mph but it's had this problem "fixed" twice in the past month already

If it has ad blue that's the mill light. Which is the emissions system fault warning light. The lack of power will be its in de rate. There be a nox sensor before and after the cat. The ecu will no what nox reading it should see after the cat compared to before the cat once it's up to operating temp. If there's a fault with the system the light will come on as a warning if it's ignored after so long it will de rate. There be a fault somewhere in the ad blue system most likely. And fixed twice sounds about right lol most people don't know what there doing so they just re program it to re set the light. It can be an involved process to diagnose. Dose it have a DAF engine

Ajamesc you seen the new euro 6 daf trucks?

I work for Delphi so would be good to see what the techs think of them, I've been involved in the development of he euro 4/5/6 daf 10 and 13 litre engine development and it's a great engine (compared to its rivals)

Ive seen one mx13 106 in with a fuel fault. They have two pumps supplying the common rail don't they. One of them pumps go's and brings an engine warning light on for fuel pressure and you have to replace both.
