R230 sl350 p0025 code

[DansE320]

Hello, hoping somebody can offer some thoughts. After recently buying a r230 sl350 the engine light came on, ran a diagnostics on obd2 and came up with p0025 code. Cleared code, everything fine for a while, then engine light and code came back.
Got an oil change( oil was very clean, no metal - although don't know when it was last changed)
And replaced the cam magnate for bank 2 exhaust ( as per these forums)
Took it out today ( only driven about 5 miles since oil change and magnate before today). I went to accelerate to overtake, engine light flashed for a few seconds and then stayed on. Loss of power and vibrations at slow speed. Drove 2 miles home. Turned engine off and started it again. Engine light had gone and no vibrations. Plugged in OBD2 scanner and the following codes
P0025
P0019 crankshaft position correlation bank 2 sensor b
P0300 random/multiple misfire
P0304 misfire cylinder 4
P0305 misfire cylinder 5
P0306 misfire cylinder 6
Could the replacement magnate by faulty?
What else might it be?
Not driven it again to see if codes come back.
Thanks

Why are you guessing? A cam magnet wouldnt cause any of the above faults!

It looks like the fault maybe something to do with P0019. My advice to you would be to find a specialist with Xentry so he can run a guided test programme.
