LNAV works ok at other airports but I don't think there is anything wrong at EGPH. The 752 is just turning too soon and rolling out of the turn before it should. The turns must be precise if you are going to intertercept a localizer as soon as the turn is completred. The LNAV in the 752 is too sloppy to execute a precise turn. A 90 degree turn to intercept a localizer is difficult. However it can be done. I flew an additonal flight maybe two nights ago from EGLL-EGPH in the 737 NGX. Following the route, the turn to final, intercept, capture, and landing went like cllockwork. So there is nothing wrong with your home airport.
If you want to waste your time you could report this to CS support. The 752 has flown like this for the four versions that I have had. You just have to be ready for anything at anytime.

Edit – One of the things I find helpful is to draw a line on the HSI that shows the airport and the runway headings per the attached image. I can use this as a reference point if I end up doing a go around because of missing the localizer or glideslope. I fly parallel to this line on the outbound leg and follow it inbound. This can be tricky at large airports because the line runs thru the center of the airport and is not in anyway tied to a particular runway so you are going to be a hair to the right or left of the line but you will still intercept the localizer of the runway.
