Fault Codes

Can anyone help identify the following codes?
[*]P1537[*]P0233[*]P0571

It kept Cutting-Out last week and had to be brought home on the back of a lorry. I've changed the Fuel Filter (which was very dirty) and since then it has run fine. But, it has fault codes stored and I don't know what they are I borrowed my brothers Tech-2 and although I couldn't find any codes under Fiat, I did find the above under Citroen.

If anyone could advise, I would be greatful!!!

I know I will just be advised to take it to my Main Dealer, but I was made Redundant the week before Christmas (Nice!), and having 4 Kids means moneys tight at present.

[*]P1537 - P1537 Intake Manifold Runner Control (Bank 1) Stuck Open [*]P0233 - Fuel Pump Secondary Circuit Intermittent[*]P0571 - Cruise Control/Brake Switch A Circuit Malfunction

They all seem a bit odd together, probably caused by voltage problem when engine cut out. These are just from my OBD code reader, but they should be the correct

Poggy - you're a star!
