Hi everyone.
I have a 98 e39 540i automatic. Recently while driving the car, it jerked and then continued driving like nothing happened. It has done this sporadically 3 times on three different drives. Any ideas might cause this erratic behavior?
TIA!
Likely a fault in the spark plugs or dirty injectors. Getting the codes read will give you a definitive answer where to look.

Symptom of failing VaNos?
(Variable Nockenwellenspreizung or Variable Camshaft Lobe Separation)
Reminds me--How do I tell if this one has Vanos?
Thanks
If it is a 98 and-on…

So NO VANOS. Thanks!
Anyone else think it could be something else besides plug or dirty injector? Trying to get a consensus on this although I will pull codes later...
Fuel supply issues perhaps.
But yea, did you ever change the guides on your car?
Wrong sub-forum.... this ain't a Fix, it's a diagnosis request.
