BMW E90 Steering Lock

sdanseo

I've an E90 320i ('05) and had two warnings pop up on me yesterday, both the master brake warning and a red warning on the LCD display.




At this stage, it drove fine, maybe sounding slightly nasally revving at low speed.

Today, I brought it to the local Indy (north county, apparently a BMW specialist) who found all of the codes below and suggested a battery as well as new wheel speed sensors. Apparently I'd been getting ELV/steering lock warnings that "weren't critical YET" and other undervoltages. He also mentioned the possibility that fuel wasn't pumping properly because of the tank design and that it might need to be kept half full.

Unfortunately when I got out of the office and tried to start the car, it wouldn't turn over, and they say the immobiliser "thinks we're tampering with the car".

Just wondering if anyone has had this problem or similar? I'll post a copy of everything they gave me below. Have left it with them until the morning.

The car also cut out while ticking over and connected to the OBD.

A year or two ago I had a similar problem when I let the battery go flat, the car threw up all sorts of warnings and before the battery eventually went I had been getting the yellow steering ELV fault and did nothing about it! My advise would be to get a new battery get the faults cleared and then take it from there! Haven't had a problem since the battery was changed!

Indy now thinks its the eccentric shaft or sensor. Time to spend €300 on a part and pay for the top end of the engine to be dismantled and re-assembled.

Is it me or is "eccentric shaft" a very eccentric - pun intended - name for the camshaft?
