Re: Power steering fluid leak/gas guzzling (archive)

Bryan, thanks for your reply. I took the car back to the mechs and they found a leak in a second ps hose. They did not charge me for labor. but the new hose costs 100.00! Amazing. I know these 750's are expensive to maintian, but holy mackerel. In any event, the problem is now fixed. The gas guzzling was due to fouling of the plugs and a faulty plug wire. Consequently, the car was firing on only 11 cylinders. Are there discount BMW parts options out there? Also, is the 750 known for high maintenance? Should I go to a more reliable 8 cylinder BMW instead of holding on to this one? Any advice would be appreciated. Thanks again, keithh the power steering hose leaking or failing? I had a severe leak, took my 750 IL in and they said it was a hole in the ps hose. They replaced the hose ($40 labor, $250 for the part!)Two weeks later and I have ps fluid all over the place again. Any ideas? Also, I know a V-12 750 is going to drink a lot of gas. But my 750's thirst seems excessive. I notice a strong smell of gas when I am at at idle and the engine seems to be running a little rough. Is this typical of 750's? Does the 750 have be kept in constant tune to avoid inefficient gas consumption? Is there something wrong with the injectors? Thanks in advance for you help. KA Seiwell

You do not say what year this is - but it sounds as though it is not new.
Therefore it is possible that you have a leaking injector, or fuel connection in the engine compartment. This will probably be move common in cooler weather. And you will notice it more if there is any leakage in the seals around the air intakes for the cabin air.

Another cause could be if you (or an attendant) are overfilling the tank (should stop when the nozzle clicks off the first time).
Otherwise the overflow tank gets raw gas and this gets taken through the charcoal filter to the engine to be burned. It can cause a rough idle and gas smell for a while after filling - depending on how quickly you use the gas after filling.
