E39 - Two questions (ABS sensors & Beisan kit)

[realcam]

Hello Everyone,

since this is my first post let me give you a brief introduction:

my name is Carsten, I live in Ireland and for the last 7 years I drive a 1998 523i (M52TU) with 110k miles on it. Best car I ever had and virtually no trouble over the years but obviously she's gettin' on a bit and I now have a problem and one other question.

The problem is with one of my ABS speed sensors.

My ABS and ASC lights are on and the fault codes are indicating 'rear right speed sensor'. So I got the new sensor but the old one isn't coming out. After over 12 years it seems to have formed some sort of inseperable symbiosis thing with its fitting. So eventually I had to brake the sensor and penetrate the remains with a drill but it's really a pain as its not quite accessible with the protection plate in the way. Meaning I still havent managed to get all of it out.

I'm not quite sure whether I should/could remove the protection plate easily and what it takes to do this? Any help pointers to information would be greatly appreciated. I would happily buy the Haynes etc if I knew I'd find something in there that's useful to my problem.

And btw, I plugged the new sensor in and the lights go off so at least it will be worth the hassle.


The other question I have is about the Beisan systems vanos repair kit.
My car seems to suffer from the very symptoms they describe and claim to address. Increased fuel consumption, not quite 'sweet' under 3000 rpm (little 'hickups' if you like), decresed power in the lower rev etc.
This started about 3 years ago and my local BMW dealer couldn't find anything wrong with it and eventually the verdict was (in not those very words but yet...) 'thats the way she is, she's getting older and that's that'.

Anyone out there who has applied the Beisan kit and who can tell me whether its worth the hassle from an effort point of view? Its quite an elaborate procedure and really only a shot in the dark after all. On the upside its not very pricy and if it works out it would be well worht it I think.

thanks

Carsten

Welcome to the Werkz.

No suggestions with the protection plate or vanos. If you car is an auto, a ATF change can solve some seemingly unrelated performance/smoothness problems, and if you haven't had it serviced recently, its not going to do any harm, but you need to get a specialist Auto shop to do the change so that they get the majority of the oil out of the torque converter.
Good luck
