You mean the reservoir up near your turbo?
You should have a matched set of caps for it to work best. If you upgrade the cap on the radiator, you should the same cap for the reservoir. Keeps pressure and temps consistent throughout the cooling system.

My check engine light keeps coming up too and cruise control light ... Car feels fine, not one issue. Anyone know of an affordable place to get the car scanned? Co worker told me they charge up to 100$ to plug it in and tell you what the issue is.. How true is that because it seems a little high ...

Is it potentially dangerous to have one cap upgraded and the other the same? Thanks!

Bryan, I highly doubt its related to your radiator cap. A system is only strong as the weakest link, which would be the other one, so in essence there shouldn't be much of a difference.
The majority of times CELs are due to electrical things such emissions sensors misreading or going bad, cylinder misfires and the like. I can help you scan it on friday if you want

The cap i replaced was rated @ a lower pressure that the cap on the top reservoir so i figured it should be fine...
I guess it has been a while since i replaced the spark plugs....
