Re: help plz

Hi Berno my interpretation of what you have written is "your difflocks are not working"!!! do the lights for the switches work? does the triangle illuminate in the instrument cluster? when did you use them last? answers to these questions may help a long distance diagnosis....

Hi Berno when you select the difflocks you should see an amber triangle light in the centre of the instrument console and the ABS light at the bottom of the instrument console and a strip of light next to each difflock switch... if these do not illuminate then check the fuses D3 D4 D5 in the fuse carrier under the dash.....

hi fixwin38 and thx for reply me!
when i diff the lock or what so ever it choose it self the front dif and the light on the button lights red only and i cant choose any other.
the abs light on the dashboard lights but not the triangle.
so i checkdt the fuses and all seems ok..?
i think its some thing with the vaccum system or so..
does you or any other here have a drawing on the vaccum system it would help very mutch...
many thx!
