£5,990    2018 Peugeot Boxer Lwb 2.0 Spare or Repair

I have 2018 Peugeot Boxer 2.0 with 130k miles on clock, that have on "low oil pressure " problem, the engine was turned off straight after the light came on and recovered to a garage, the oil pump was checked and it is in working condition so it is a different issue, also the engine makes noise a sound. I'm the 2nd oner of the van and I've been used this van for sameday courier so it's mostly motorway mileage, it was well looked after and regularly serviced but I don't have any service history as work has been carried in a small garage(the van is in there at the moment) recently changed the EGR cooler, and all 4 injectors(still need coding), the ad blue and DPF are deleted.
