My 88 750iL 82000km is having this steering problem. The steering very often went to this mode where it has no powersteering! Then when turn off and restart, everything seems to be okay... and it will only last for about 10 mins or so and then it is back to the same old problem! Lately it is more and more often! What is the cause anyone have any idea? It is because it is a intermmediate problem and it had my local manchanic iffy on what to do next! So... if you have had the same problem before, your kind input will be much appriciated! Thank you very much in advance! Happy New Year!
