Car Forum / BMW Cars / August 2006Mystery switch.
On a 1997 model UK E39. Plunger type switch fitted in a vertical plane to the front of the l/h microfilter housing. The plunger part has a cross moulded on the top of it, (positive something?) and on my car is in the down postion. Pull it, and it clicks into a secondary position. Does anyone know what it's for?

The only item I can remember from my old E39 with a + on top was the battery connection point for the positive cable of a battery charger. The + was a hinged cover that revealed the metal terminal. Any help?

The plunger part is about 10mm or 3/8" diameter. The connecting plug has 2 thin wires. One purple and green wire, the other brown, that disappear into the main harness.

Ah this is the one that adjusts the brake sensitivity - you had it switched to the MAX setting ;)  Signaturejeremy ['01 BMW 530iA SE Touring] IIRC, the hood position switch.

That's what I thought initially, but it's too low. With the hood closed, there is at least 1" between the hood and plunger.

I finally found it in the Bentley manual. I'll have to check the clearance again, because my original check showed it wasn't touching the hood, and there wasn't a mark on the hood to show that it ever had been touching. Mike. |
