Ok back in June I took my 2006 CL500 on a road trip 800 miles round trip. During the trip ocassional got the dreaded white ABC visit workshop message. Never went red. Restarting the car the message would go away. Checked fluid and hoses no leaks. Purchased a scanner and found stored code C1148 presure related. Cleared the code and all was good till a couple of weeks ago. The white ABC warning and C1148 code is back. It shows up after the engine is at running temperature. Restart back to 190. Scanner shows ABC pressure goes from 190 to 255 bars when warning occurs. Is this a bad B4 pressure sensor or is the pump bad? Is it safe to drive? Attached scanner outputs.
