Hi i'm new on here so hope you can help me, i have a p38 DSE and have just had a new diesel pump put on. Since getting it back intermitently when i'm driving on the motorway, if i lift me foot off the accelerator quickly there is a light comes on the dashboard ( yellow light like a cylinder with a cone one the end with 3 lines coming from it) and loose power for a few seconds, if i pump the peddel a few times it takes off again!! Help please?
