Fuel pump would be my first guess, too. Like Bob said, listen for the whirring sound in the back when the key is turned to the first position. A similar thing happened to my E30 a couple years ago. If you don't hear the sound, check the connection under the back seat with a multimeter to make sure that current is getting there.by Dave_G - Technical Forum
Yesterday the Sports Car Club of Vermont held an ice time trial on Mallett's Bay on Lake Champlain, and I took the iX out to have some good fun sliding around on the ice. It had been a couple years since I was last on the ice, and it was great to get back at it. As usual, the iX proved its prowess on a slippery surface. Here's a video of my fastest run of the day.

QuoteJose PintoThe car to be serviced by the owner with a simple set of tools is old history. This is EXACTLY the complaint that my dear old Dad used to make 40 years ago. He also complained about planned obsolescence, cars not lasting as long as they used to, etc. etc. The more things change, the more they stay the same. The thing is, my Dad was wrong. Like him, I love old cars as much as anyby Dave_G - Community Forum
Well, that was weird. I tested all four sensors, found the one in the front right that was different, and confirmed by spinning the wheel that the resistance on that one wasn't changing. OK, bad sensor, and I ordered a new one. The next day I got a call back from the vendor saying that ABS sensors for the iX are pure unobtanium. Even BMW in Germany doesn't have them -- they needed toby Dave_G - Technical Forum
QuoteMichiel 318iS Checking the '90 iX electric scheme, I figured out the E30 is not using Hall sensors, but magnetic coils (so no need for a power supply when testing). Have you tried reading the signal when rotating the wheel? Best would be to use a scope, but a DVM should read something as well (though not accurate) in the AC range. I haven't had a chance to check that yet (busy wby Dave_G - Technical Forum
QuoteMichiel 318iS Are you sure the wiring isn't broken internally? On my E46 I had the pad wear light on intermittently, flickering at times. I'm pretty sure, based on the resistance test I did at the connector. The sensors have a fairly long wire, so the connector is quite a distance away from the sensor. The resistance was < infinity, indicating a connection, and was the same onby Dave_G - Technical Forum
QuoteBob in Everett If you turned on the ignition while the sensors were unplugged, for sure the computer set the warning light. That light may be difficult to reset. There is a special tool that plugs into the 20 pin connector and has some buttons on it to connect various pins and an internal circuit. Thanks. I actually have a SIL reset tool, but I don't think it does the ABS light. Anyby Dave_G - Technical Forum
A while ago I removed both front struts in my iX to replace the upper strut mounts. (These are different from regular E30 struts, but the basic principles are the same.) After putting it all back together, I began having a problem with the ABS, where the ABS would engage at very low speeds, like when coming to a stop. Since the only thing I had changed since before the problem started was the froby Dave_G - Technical Forum
Peter is correct -- automatic transmissions are designed to be left in gear. Any load placed on the engine by idling in Drive is trivial to the point of insignificance. The wear placed on the shift linkage from shifting back and forth is probably higher (but also insignificant). Here in the U.S., where automatics are the rule rather than the exception, what drives me most crazy is people who dby Dave_G - Car Talk

QuoteBob in EverettMight try a bit of dielectric grease from the auto parts store on the connector pins. That was going to be my next plan, until this morning when discovered that it's working again!

QuoteBob in EverettMaybe the connector to the resistor block just needs to be cleaned. That's exactly what it was. I pulled it out, cleaned the contacts, and tested it -- it worked on all four positions! So I squeezed the cover back on, screwed everything back together, and... position 1 isn't working again. So I went and had a beer and will deal with it again tomorrow.by Dave_G - Technical Forum

I've been listening to the blower motor in my iX chirping and squeaking for a long time, so when it finally died altogether it was no big surprise. I just replaced the blower motor with a new one, and before buttoning everything up, decided to test it. It works perfectly -- in positions 2, 3, and 4. In position 1, there's nothing. Before it died, the old motor was working in all 4 positby Dave_G - Technical Forum

Quotebam_loves_his_bmw_325i My E30 is missing the blue and brown sensor plugs. Not missing, mind you, but my temp gauge doesn't read accurately and I've been suspecting it to be the cause of many problems like running rich, shiesty performance and poor economy. I'd like to replace them and see what happens but there are few yards with e30s around here and the OEM replacements aby Dave_G - Technical Forum
I third the wheel bearing diagnosis. I don't know why it has to be the rear one, since I've heard front wheel bearings also make strange noises (though not like yours).

It's easy to see any fuel pooled on top of the tank if you pull out the seat bottom and remove the two acby Dave_G - Technical Forum
We only got about 6-8" (20 cm) up here in central Vermont, not as much as coastal New England got, but enough to go out and have fun skiing up on the mountain.

Surprisingly enough, WD-40 works very well for this. It's worthless as a penetrating oil, and a terrible lubricant, but it's the best thing going for removing the gunk left behind by duct tape, and probably whatever tape you used.

The big thing to consider when buying an iX is the condition of the viscous coupling in the transfer case. They are tough as nails and last forever if treated well, but have an Achilles' heel if they're abused. By "abused" I mean towing with only two wheels on the ground, or any other action that forces the front and rear wheels to turn at different speeds. If that happens, thby Dave_G - Technical Forum
