Guys there are several BMW water bottels that are very similar to ours. one with sensor, one without, one with the same cap, others with differnet caps... The price for the bottle, lever sender and cap are - at least here in gemany - much lower than the price for a metal bottle. And just the fact that I can see the water level even without lifting the louvre is a reason for me to keep it in the car. As long as thre are no metal bottles with low water senders I won't install them anymore. (LAMBDA light will be activated and a buzzer will inform me, too.) It's nice to have stainless steel in the engine compartment, but it's even nicer to have a non overheating engine :-) I guess DPNW can help you to get those BMW water bottles in the US. Elvis & 6548 Nothing's exact, but wander thru the boneyards looking at 1984-1991 BMW 3-series (i.e. 325). The 5- series probably uses something similar. They use a more square-off plastic bottle, mounted on the drivers side of the engine compartment above the fender. There will be a level sender in the bottle. It is NOT a bolt-on replacement, you will have to adapt hose size and mounting. If I recall correctly the hose attaches at the bottom of the bottle rather than one end. Make sure you get the electrical plug for the sender i.e. cut it off the donor car. Once you figure out the fit, you can get a brand new one from the dealer or likely from Bavarian Auto. Probably for about the cost of a stainless DMC bottle. As for your original question - I have several original (very used) plastic DMC water bottles laying around from metal conversions, none of which I'd trust on a car that I was driving farther than the local K-Mart. They hold water, at least they did when removed from the car. What's it worth to you? PS - Doesn't your 928S have a similar bottle on it?
