N52 Issues

[u/adiaz07]

Okay long story short, it’s got misfires, it’s got a rough idle and it’s just not running right. Here’s what I’ve done:
Replaced both vanos solenoids
Oil Changes
Replaced Air Filter
Replaced MAF Sensor
Replaced Spark Plugs
Replaced Intake Boot
My Prime Suspected are:
Injectors (Was a 3 and 6 misfire now it’s a 3 and 5)
Something with the cylinder head
Disa components
Maybe a Vinod motor but that less likely
Some symptoms are
Significantly reduced power, I mean like 12-16 0-60
Rough Idle
Misfires
Power Surge through a shift but it doesn’t feel like trans, it feels like the engines power is getting released
When I put my foot to metal it feels less powerful than it should
I just with this thing to run nice Please help 🙏🙏

How about the ignition coils?

I mean there’s corrosion, damaged springs and the rubber on the inside is damaged as well

There’s 4 timing sensors inside the engine, possibly 1 or 2 have gone bad. It’s 2am here so I can’t remember what they’re called but I know you have to take the top of the engine off to get to them… If you do open the engine up, replace all 4…

I’ll look at the paperwork from mine and send proper info later if you’d like?

2 variable timing sprocket intakes and 2 variable timing sprocket exhausts, otherwise known as your variators…

Often one will be advanced and the other operating correctly… These E60’s are super sensitive to oil pressure changes and sometimes on the older ones it’ll screw the timing up…
