Had a P0520 code - bad oil pressure switch. My pressure was pegged at 99 on evic. Took it in and they replaced the oil pressure switch and a few other things. Pick it up last night and it was still reading high (90+) for the first 10 minutes of driving. Then it settles down to 40 plus or minus a few. This morning start it up and same thing. The first 10-15 minutes of driving it's reading 90+ psi. Then it drops to 42.

I'm going to give it a few days before I call back, but just wondering if anyone else experiences this. I think I can assume my oil pressure isn't 98 psi or I'd be blowing oil all over the place. Also I noticed during this time my coolant temp creeping up to 225, but then settles back down to 208. Not sure if it's a related problem?

It is not uncommon for the oil pressure to be that high (or higher) on a 'cold' start. It will gradually drop as you described when the engine warms up.

Coolant temps also run high on the 2014, with high readings of 225-228F being quite normal.

It seems everything is normal.
