I put the high beam relay into the low beam relay socket, and now it works!
So a relay can be broken also if its clikcing...

Already done that, thanks

parking lights always work, but not low beam. I can hear a little click from the relay when i switch on the lights, but not even half as loud as the high beam relay. park lights rear and front is still on when low beam is on. Do I have a broken relay???

My 528i has too high idle speed, when cold about 2300rpm, hot about 1300rpm. I have adjusted the ignition, co and the throttle damper. before this it was about 1500 when the engine was hot.

First, SORRY for my bad "english":) I am restoring an E12 1975, and it has lots of rust... I need this: http://de.bmwfans.info/parts-catalog/E12/Europe/525-M30/L-M/browse/bodywork/side_panel_tail_trim/ Is it called backplate..? The car is from 1975 before the facelift. Does anybody know wh...

Hello all E12 people!
I need a repair kit for the main brake cylinder, but in the shop there are two different sizes on the diameter, 23,81mm and 22,2mm. Which is the right one? The car is a 525 from 1975, left-hand drive:)

The wire goes to the input to the relay, so it doesn't bypass. But where is this wire coming from?

I don't have the key for my old 525 from 1975, but i have the "key-code" that is on the ignition lock. Is the key for the door and trunk lock too, or only the ignition lock?

The problem is found! It's a broken wire to the combo relay. When the engine is cranking, is only the cold start valve opening. When it fires is the other injectors activated of the wire that is broken. So i made a wire from the relay to the ignition lock, so when i turn the key, the injectors are o...

Are you sure you are getting fuel to the engine? Could be a bad pump or cracked hoses. Yes, the pressure is ok and the fuel is new, but the injectors are not opening. it starts but stops after a few seconds because the cold start valve is opening. So everything is fine without the injectors that do...

The engine hasn't been running in very many years, and it doesn't start because the injectors are not opening, only the cold start valve. I have changed 2 relays next to the brake cylinder and the control unit for the injection, both things are used. What is wrong? If I take 2 wires direct from the ...
