Hi All,

I have the slight jerking or loss of Power for about 15 min of any initial drive.
Dealer said to walnut blast it, so I did.
I have to admit, this fix about 80% of the jerking.
Now it is clearly in the begining of any drive.
ex: either cold or normal hot temp.
shut car off, go into store buy a pack.
car off for approx 5-10 min.
start driving and under any type of acceleration, car jerks as if, Power is losing, then comming back repeatly unless I feather the gas pedal.
No codes ever, untill yesterday.

was in WA. stoped for a pack of smokes, and enter destination into my iphone for a new address 18 miles away.

I5 (interstate) was 30 sec away.
Got on it, traveling 120 km/hr.

about 3 min into drive, ...Half engine check like and Limp Mode displayed on my idrive.

Got home, and scanned my car using my laptop K+DCan cable and DIS v57.

Please see attached screen captures - 2 pages but here is what i got.
Now I am not sure if my Jerking issue is related or not.
Can someone point me in the right direction of fault?

Car is 2007 335i Sedan.
Built Date Sept of 2006.

Clean VANOS solenoids. Google how to do it.

Almost all of those are battery/power-related. How old is your battery and have you verified that all of the battery connections are tight?

The Battery connections are solid.
Dealer stated, that when battery was changed, they did not enter the new battery into the ECM.

Planning on doing it myself, but havn't got around to it.
Just Been too busy, but not forgotten.

Fix your battery problem first.
As a low battery can cause all kinds of false errors with the electronics
of which these cars have in abundance . Then clear the errors and do
a another pass with DIS57.
Also there what are the dates on the error's most of this could be stored codes from before the battery change.

Ctuna, the battery codes were there before I owned this car.
The rest are recent like with 2 weeks tops.
