2010 s150 that I may purchase has code 1/ 7906 or something like that. ???

I held the headlight button down and after 5 seconds either a "v 7906" or 1/ 7906 showed up. It flashed between that and the number of hours. What does this mean? Also, at full throttle, there seems to be a hydro pump whine, almost like the sound of a car horn. If I back the throttle off, just a touch, it stops. Any ideas? Thanks.

Check your hydraulic fluid level. Also, check the condition of oil. Is there any clouding or foaming of it?? Have you seen any signs of leakage??

Well, I think I got some bad info. It is not the headlight button that I need to hold down. It seems I need to hold down the info button.

I will check the hydraulic level. Thanks.
