can the person who told you it was the pump explain why that is the fault,is it his/her money that will pay for a new pump?If he/she is guessing then it may be an expensive one at that,I take it no management lights are on and it has been on a code reader,all filters are clean and up to date,no split intercooler hoses,play in the turbo impeller,before a new pump is fitted there are loads of checks I would do before going down that route.
