Automatic headlight sensor and squeaky front end
I'm quite happy to have found a place where DIY still exists.
I've read some posts, I like the attitude that we can fix it just as well as "they" can. I'm sure there are required trips to the dealer but I'd like to limit that.
I've got a new to me 2007 GL320 with 111k miles on it.
There is a MB modification sticker under the hood saying the hoses have been altered, I'm assuming the turbo hoses that people had trouble with. (See, I did read some)
My issue is the automatic light sensor seems innoperative according to the display. I'm gonna guess the sensor responsible is either part of the parktronic system on top of the dash or closely integrated. Suggestions?
My other issue is a squeaky front A-arm air strut/shock in the front drivers side. The selling dealer replaced both front and rear air shocks in order to inspect and sell vehicle. The front makes a creaking groaning sound when braking. I'm assuming it is suspension cycling or lateral stress on the lower A-arm.
Silicone spray? I don't want to degrade any bushings or air bladders.
