83 533i questions

[Mythic]

Hi Everyone,
I just bought a 1983 533i and am looking to fire some questions around.

1.inspection light ? do I have to go to BMW to get this reset and ultimately turned of ?
2.what weight oil should I run ....I'm open to brands recomended too
3.the bumper molding is wavy and I was wondering if there is a way to flatten it out again
4.if all the windows work except the passenger front,does this pretty much mean that it's a motor prob or wiring to that window...if it was a fuse none of the windows would work right ?
5.speedo? isn't working all the time,I test drove this car twice and it worked each time.The night I took it home it worked and not long after it stopped and will ocassionally work if I hit a bump ....any ideas where to start trouble shooting this ?

hmmm I think that's all I have for now ....lol for now
anyone have any tips or facts about my car feel free to drop an msg.Like I said I just bought it and would like to learn lots about it.

thx in advance for any and all help

1. SI reset and batteries

With the ignition switch at (position two) and the engine not running, grounding pin seven #7 of the diagnostic connector to pin one #1 for approximately three (3) seconds will reset the oil service lights. Grounding pin seven #7 to pin one #1 for approximately twelve (12) seconds will do an inspection service reset.

1. Ground
4. Temperature sensor
7. Reset
8. TDC sensor yellow
9. TDC sensor shield
10.TDC sensor black
11.Start signal
12.Alternator charging excitation voltage
13.Ignition coil
14.Alternator charging supply current
15.Oxygen Heater

It will signal an oil change need between 5k and 7k depending on your indicated speed since the last reset. It will signal stealer inspections at all the predesignated miles.

SI Board Swap Out

Last but not least - the SI Board. Above is a new SI Board with lithium batteries and below is the old one. Note the blown battery on the old SI Board (green circle). The light blue rectangle shows the actual service indicator LED's which appear on your dash display. These LED's are mounted on a separate circuit board which must be pulled out of the old SI Board and plugged into the new one. This is an easy task. The purple arrow shows the orientation of the SI Board relative to the driver.


If it fails to reset then you need batteries.

Varta battery 500RST OE part.

Radio Shack: part number 23-191: $6.49 for set of two; they come w/solder tabs on them.

1.2 volts / 700mAh

Charge fully B4 installation on SI board.

Consider mounting batteries "remotely" under dash, etc. in separate holder for easy removal in future (i.e. not pulling the console out and apart); you can buy a plastic holder at RS. Run leadwires from holder to SI board connections. Makes life easy if you ever need to replace batteries again.

From Radio Shack, get:
1) You'll need a twin AA battery holder ($3)
2) 2 AA NiCAD rechargeable batteries ($6)





4. Change the window switch with a know good one to determine the issue.

5. The speedo is powered from a sender in the aft side of the differential.
Most issues are the connector at the aft face of the differential.
