Unhappy Are my data logs normal? HPFP going out?

So the other day, I was just cruising down the road and my car gave me the infamous “Engine Malfunction” (half-check engine light) on my iDrive. I went home and scanned it with MHD on my tablet.

29F2 - DME: Fuel high-pressure system, fuel pressure

The next day, I deleted the code and drove around town a little and did some pulls.

It didn’t return.

I took 2 data logs as well that I have uploaded to DataZap.

Previous owner of my vehicle did do the HPFP Recall, so the car is on its second. Only at 75,000 kilometres as well!

Please someone give me some feedback/advice on what to do next! Not sure if i should replace it, or if it was a faulty sensor of somesort. Thank you!

Anyone have any insights? Suggestions? 29F2 code hasn't returned since that scare last week, so I'm hoping it was just a one time thing.

Fuel pressures look fine in the logs shown. Your lpfp drops to a low of 55 which is acceptable and pressure at rail dropped down to 1600 which I think is acceptable.
