engine management light came on due to DPF pressure sensor.. has now been changed but light is still on. Any advice on this?

car was sent off for a new clutch and they changed a centre sleeve on the exhaust and now car has flashing coil light down to EGT sensor 4.. and now particulate filter light has come on also...
haven’t changed the sensor as of yet due to not knowing location of sensor.. a few people have mentioned it is the second sensor after DPF is this correct? And also would changing this resolve the issues as they are the only 2 codes coming up when plugged in?

Any advice please?
Thanks.
