(Help) 2015 Sl550 Oil pump solenoid

I was attempting to unplug my oil solenoid and pulled it out. I could not get it back in. I believe it is broke. Can someone help me with a part number for a new one? There is a hole where the connector was, but it does not leak while the engine is idling. Please help with


suggestions. Thank you

okay. The plan is to buy a new connector with an o-ring and to install. Worst case, the connector will need to be cut short. Whatcha say? It is already unplugged and I didn't plan on plugging it back up. I guess the oil pan has to be removed to fix correctly. Cheap plastic. I thought that was a BMW thing!

I am an idiot. If you ever find yourself in a similar situation, just go and get your a rubber plug with a taper. Problem solved. TY

Sorry no one replied to your thread.
I am not so sure it is posted in the proper forum.
R232 is SL43 SL55 SL63.
If you posted in the R230 forum, you might get some guys there who would be knowledgeable.

Sorry, R231 forum

Post this in the R231 forum.
The 2015 SL550 is a R231, not R232.
Wish I was more help.
