Hi Gang,

I am having the opposite problem that most people have with ASF and Vehicle Too Low. If my car happens to pump up the struts and I park it, they will stay pumped up. But when I start driving, the front goes down and I get the ASF and sometimes the VTL messages. It will sometimes pump back up when I am stopped at a light, or if I restart the car. Occasionally even after it is turned off it will raise, but not while I am driving at any speed. It does not throw an OBDII fault code when the ASF light comes on. It hasn't shown a VTL message since I plugged in my OBDII so I don't know if that will throw a code. Will update this if it does.

Relevant facts:
1) The left front strut was leaking very slightly so I replaced it. No difference.
2) I had the rear jacked way up about 3 weeks ago when I replaced the lower control arm bushings. The problems started about a week ago (2 weeks after the repair). Don't see how that could be relevant, but . . .
3) The car has ~150,000 miles on it.

EDIT: The car has been sitting for a couple of days. The first day, no lowering at all. Last night overnight all 4 struts lower and I got the Vehicle Too Low message. Still no codes on OBDII. It raised back up within a few minutes of driving about 20mph.

Any thoughts are appreciated.
Mike

 

Shocks as well as tires are best replaced in pairs,or all four at the same time I M H O.
Have you replaced or rebuilt the compressor yet?
If not at 150,000 miles it's way past time.
My i930 will tell you which shock is leaking, or some idea of where to start looking.
Don't know just what, but something seems to be loosing air.

 

Hi WIngrider (does that mean you ride a Goldwing? I do)

I agree about replacing the struts in pairs. All of them have been replaced already, this is the second time I replaced the LF. I was hoping to get by with that since the RF doesn't seem to be leaking. I'm going to take your advice and rebuild the compressor. It's cheap enough and, as you say, overdue. I'll post how things are progressing.

Thanks
Have a great weekend!
