While pulling out of a parking lot the other day the ABS,ACS+T and transmission lights al.l came on simotaniously in my 99 BMW 5281. The car was operational but sluggish. I pulled over and looked up these lights in my owners manual. The manual said to turn the engine off and apply the parking brake and restart the engine in a couple of minutes. This did reset the transmission. The light went out and I drove the car without a problem.The same thing happened again two times the next day(I reset the trans malfunction again). I'm told that the car needs a new ACS moduleand that the cost would be $1150.00 for parts and labor. Does this seem like a correct diagnosis? And if so, is the price for repair right?...I should also add that the trans hasn't been a problem for the last couple of days. But, while driving I noticed steam coming from under the hood today, the car ran hot. I tried to make it home but, after a couple of miles the motor turned off and the car was hard to steer. I let the motor cool off. i put antifreeze in the rad and drove it to an independant repair shop. They said that i need a water pump and belts for the cost of $522.00. Is this anywhere near the right cost?...................... Jean

Well you have two separate issue, ASC modules are fairly common but so are wheel speed sensors, which should have been checked. The waterpump failing is wear and tear, should not have been driven in the state it was in, ignorance is bliss, but get it towed when you see smoke or the temp reaches red, heed this warning or you will be up for more than these repair costs, considering finances does seem to be a cause for concern and the cooling system would not be linked to the ASC in anyway. Repair cost is normal. Its a BMW...
