2005 320d Rear Parking Sensor and steering wheel audio controls not working

Hi everyone

I recently had a car audio "specialist" change out my BMW stereo with a Kenwood so that I could hook up my iphone and everything seemed to go well. I have a 320D SE...

Unfortunately, the steering wheel audio controls don't work and when I asked the "specialist" about this, he said it was most like a blown fuse but that he would check whether the unit Kenwood supplied needed to be activated.

Well, I heard nothing and so resolved to change the fuse myself. Doing a bit of research, the Kenwood steering column adaptor should just work once connected.

However, I nearly reversed into a wall prior to changing the fuse as low and behold, the rear parking sensor is no longer working. I opened up the glove box and checked the wiring diagram. It looks to me as though the fuse is not the same for the PS and steering controls so I'm reluctant to believe the problem is with the fuse (unless the audio guy was REALLY ham-fisted).

Does anyone have any ideas? Since I live in Ireland, I want to hold off taking it to one of the local BMW dealers (they wear masks by day!) so any thoughts would be greatly appreciated.

Have you actually taken the car back back to the Audio specialist or just spoke to them on the phone?

If the steering controls were fine before hand and the Kenwood stereo is supposed to work with the controls then the ball is in their court and they should put it right.

Thanks for the replies guys - the car is actually down in the body shop having a couple of dings taken out but I'll have a check on the PS wiring when I collect it.

The audio guy is a bit of a tool to be honest and I'm not really keen on having him anywhere near my car again!

Thanks once more for the help!

Sorry to be dumb but are we talking about the tray right under the steering column which is held in by some phillips screws?

The lad who was working on my car last week said the "computer says no" there's nothing wrong with the car so I'm hoping it is just the speaker but I must admit, I know NOTHING about how my lovely car actually works :)

(Other than: "put diesel in here, right pedal fast, left pedal slow")

:)

Thanks

Well, this weekend I dropped under the steering wheel and took a look under the panel which is fixed by a series of diamond head screws. Lots of secure cabling, nothing looks out of place but I don't know what it is I'm looking for re; the actual speaker.

I'm going to a BMW dealer on Friday for an oil service and MOT so does anyone know what I can expect from their guys in terms of costs for checking out the PS problem?

Is it likely to cause my left arm to go numb?

Cheers!

UPDATE!

So I got the car serviced and MOT'd by Wayside BMW, Milton Keynes today. I asked them to also take a look at the PDC as it wasn't beeping.

The result?

"The head unit you are using does not *support* the PDC."

Ok. So I'm a little bit surprised at this response (not to mention the fact that Wayside returned my car to me covered in a weird tree sap).

Not impressed at all... anyone have any comments / believe that the Kenwood stereo doesn't *support* the PDC?

Yes! That's EXACTLY what they're saying!

I thought it was a bit weird to be honest. I mean, earlier posts mentioned that there was probably a connection not connected under the dash but I can't find anything out of place.

I'm really struggling now though as both problems still persist:

1) no PDC
2) no steering column controls

And the BMW guys at Wayside BMW telling me "your head unit doesn't support the beep"...

OK, both our E90's have speakers in pretty much the same place as the E46, they are mounted on the removable panel that screws to the underside of the dashboard, between the pedals and the steering wheel.

However! Both our E90's have PDC front and rear. The front obstacles are announced through the little front speaker, rearward obstacles are announced through . . . . the rear speakers!

Seems BMW may be right!

Hmmm... I think it is the Professional but it's back in Ireland so I will check when I get home on Monday.

I've just been giving myself a cricked neck, taken off the panel and I can't see a speaker. The felt soft bit is there but it's not attached to anything and I can't see a speaker where I would expect to see like a cone or something.

Worst case is that it isn't working: is there a way around it?

Morning all

Just saw Deanos post about an adaptor for the E90. Would anyone know the part number so I can get it ordered and fitted?

Also, any thoughts on why the steering column doesn't work anymore? None of the audio controls are working since the install, despite the Kenwood steering control kit being fitted.

Cheers
