Car: 2008 E92 335

I my rear quarter panel repaired at a body shop and now my instrument cluster fuse (Fuse 74) keeps blowing (instantly). I removed my PROcede just to rule that out and itÂ’s still happening.

IÂ’ve searched the forums and others have had this problem when disconnecting the battery (which the body shop did) or after coding (I have not had any coding done). Some say to disconnect the battery for an hour and others say to put the fuse in while the battery is disconnected and then hook the battery back up. Both of those have been tried and itÂ’s still happening. I canÂ’t find a definitive solution. The body shop checked over everything they did looking for anything wrong like a pinched wire and found nothing.

I believe the OBDII port is out because it's on that fuse. I haven't tried my Bavarian Technic cable yet because I don't have it with me.
UPDATE: BT Tool doesn't work, so the port is dead.

I have these codes (I read it with the PROcede before I removed it):
2DE4
2DE5
CD94 = Message (outdoor temperature)
CD9F
CDA8 = Message (cluster state)
CDAE

Does anyone know what those codes are because I can only find 4 of those

Does anyone have any recommendations? Thanks for your help!

No comments from anyone?

Do you have an additional devices on the car.
That particular fuse usually blows when applying battery
backup through the OBD port when changing the battery.
Also is it the correct size fuse?

[usc335]

No other devices on the car and the fuse size is correct at 5 amps.

Start from checking all pins connected to Fuse 47 for shorts to ground. There are only two options: it's either the cluster or OBDII port.

2DE4 - DME: fuel level sensor, left: signal
2DE5 - DME: fuel level sensor, right: signal
CD94 - Message error (ambient temp./relative time), DME receiver, instrument panel transmitter
CD9F - Message error (mileage reading) faulty, DME receiver, instrument panel transmitter
CDA8 - Message error (status, instrument panel) faulty, DME receiver, instrument panel transmitter
CDAE - Message error (time display) faulty, DME receiver, instrument panel transmitter

Problem Solved! All I ended up doing was disconnecting the Instrument Cluster, letting it sit for a couple hours, and reconnected it. It fixed itself -- go figure! Thanks for the help!

Instrument cluster? The entire dash cluster? Mine didn’t light up at all during start up, couldn’t read rpm’s either until seconds later and had all these codes pop up.

What and where does this look like to disconnect to fix this?

Before you remove and unplug the cluster, check the fuses in the back of the glove box. If its blown, disconnect the battery and then replace the fuse. With all the warning lights tho it sounds like alternator should be tested.

I think it was my short 4 mile drive in 32 degree cold from home to Home Depot that did it. This car sure does not like the cold so I've been having it sit on a tender now. But if the fuses were blown, would I unplug them individually and assess each pin or just a no touch visual once I remove the glove box cover?

Don’t be intimidated by the fuse box. YouTube it and you’ll see exactly where it’s located, you don’t even have to remove the glove box. There’s a little card in there that gives you the map of the fuses (ie fuse #74 is OBC/cluster, etc). And there’s a white fuse puller tool also in there. Just check the fuse that relates to your cluster and if you see anything broken in the fuse go grab another one at the parts store. Then disconnect battery and replace fuse... I’ve heard of them continuing to blow if you don’t disconnect battery. I’m having cluster/obc problems and wish it was as easy as the fuse! Good luck

Do I unplug the battery first before pulling fuses just to check?

Nope , you don’t need to

Ah the classic turn it off, leave it, turn it back on again. I had an old computer that I gave up trying to fix for a week. I let it collect dust for 6 months before I decided to give it another go. It started up like nothing was ever wrong with it.

I am having this issue, E90 328i. My fuse blows after a going over a bump lmfao
