major headache :(

[brento]

well been puttin my remote start alarm in the last day and having big problems its finally well nearly workin and now the gauges have gone wack . the temp gauge is reading full. does anyone have any ideas???

[Martinaston]

Undo what you did until the guages work again then put it back in properly.

[Chaos]

make sure u dont leave it in gear when ur using it either.

[brento]

mmmm
the alarm is fully unplugged
still doin it an when i put headlights on it makes tacho stuf up and also makes the temp gauge move around
i think if stuffed my bmr

[Chaos]

might be unrelated m8, sounds like a possible SI board problem

[Martinaston]

I'd start with the tacho sensor wire on the alarm sound like you got it mixed up with one of the outputs.

[brento]

mmm
just took the negative wire off the battery for 10 min ill c what happins
there was a fuse gone but i have replaced it and it didnt change anything

[brento]

still no luck
does anyone know if u can reset ur clusters?? maybey taking the battery out . my fog when the engine is started the fog lights make the gauges go up and down same when u play with the main headlights has anyone had trouble with there clasters like this b4???

[Martinaston]

Well you've got me stumped. But if you de-solder the internal battery they are sensitive to heat and if you hold the soldering iron on them too long you ruin them. The best thing to do is strip the unit and remove the circuit board and let it drain or place a load across it to speed it up as it can hold a charge for weeks.
If you have a motronic management system there is a white plug on the front below the temperature guage that is specific to the angine size, if you have the wrong one all the dials work incorrectly. But if it worked before you fitted the alarm then the best thing to do is pull it out and start again and make sure you have an accurate wiring diagram for that year of car. The haynes one is not bad but not 100%.
Did you link any of the alarm output's to the headlights?
Do you know it's a good (working) alarm?
What fuse did you blow?

[brento]

i have taken disconeted all the harnesses to the alarm doesnt help
its fuse 23 and the fog light relay is makin a weird noise when u hoit the fog light swich wich makes the gauges go weird..

[brento]

well ill be takin it to an auto elec on monday its got me beat im just hopin its sumthin small like a bad earth or sumthin and i havent damaged anything

[Martinaston]

That was the only other thought i had was a bad earth under the dash somewhere.
When you say you dissconected all the harnesses Do you mean you just un-plugged them from the alarm?
If so check all terminals for the voltage if the eqipment it should be connected to.
Happy hunting

[brento]

the alarm harnesses have been de soldered and it is all back in normall

and if u think it couldnt get any worse now my car wont start properly it takes me so long and it idles funny for ages and then it is ok

i will have to take it to bmw to get fixed.....

[brento]

just thought of sumthin
maybe beasue the temp gauge is stayin on full (playin up) the ecu is thinking the car is already warmed up thats why it is idleing crap and so hard to start and then after 10 minutes it is ok
