Citroen Xsara Picasso car suddenly slows whilst at constant speed, have code p1537

Car: Citroen Xsara Picasso
Variant: 2.0 hDI
Model Year: 2003

Categories: Electrics, ECU, Warnings & Lights

Whilst driving at a constant speed, it can be 30 mph, 40 mph or any constant speed, the car will suddenly slow as if you have taken your foot off the gas pedal. Sometimes it will pick up itself, but sometimes you have to back off the gas and then put foot down again. Although the engine light has never come on there is code P1537 stored in the computer
Can anyone please shed some light on this and suggest a fix
