Hello W140 owners. I've posted here once, but need more help. My mom purchased a 92 300SD and has some problems that I've been searching high and low for and can't seem to get a clear answer. The car comes with some problems...
1. Its sluggish. (both parents complain. I haven't drove it yet..) I check the turbo with a vacuum gauge and it works, but I don't really hear that familiar turbo whine; even with the windows down.
2. The automatic climate control air direction buttons don't work. Only auto lights up and pushing the other 3 buttons does nothing.
3. Center air vent doesn't blow air. It did like twice, but then when I push some other button it stop. Air does come out the sides, top (dash) and rear vents.
4. Transmission flares while shifting from 2 to 3rd. But when foot is at the right position (speed is about 25 and rpm is about 2000) it doesn't. Again, judging from parents driving. I saw a youtube vid on adjusting this, which I'm gonna try, but I'll wait for your guys opinions.
5. If I pull fuse 9 to reset the door closing assist, the two front doors will assist close, but after a while, it won't. Leak somewhere or bad pump? but both pumps work as it should. Times out correctly and stuff.
6. ASD and ABS lights on. ABS light comes on when you step on the brakes and stays on after that (after starting the car of course) ASD light stays on when engine is running.
This car is a bit of a challenge for me, but I'm willing to learn and fix it. I'm more use to the simpler ones like w123 and w124, so I'm handy. But since we've bought the car I'm basically the one searching up and trying to find cures for these problems, but haven't really found a straight answer. Well I hope you guys can help me out with this one as I'm stepping out of my comfort zone and taking on a challenge Thank you Sorry if this is too many problems to assist at once.
