Help! Cluster Freaking out, throwing codes and now car hesitates when starting

[project jayden]

the past couple days have been going from bad to worse for me. Initially my cluster gauge needles were going crazy. Either not turning on or bouncing erratically. The ABS, DTC, Red Brake light, Service lights etc would also go off as well. I did a little research and it seemed like the battery could be the issue so i ended up replacing it with an Odyssey AGM battery. Registered it, cleared codes and fired up the car. Drove it a few miles and Initially it seemed like the issue was resolved. Parked the car for the night. Early the next morning fired up the car and it hesitated. Took at least 3-5 seconds to fire up..this time around a yellow brake light and I-drive malfunction symbol came up. When i got to work checked brake reservoir and brake fluid was at max. Few hours later took my lunch break and tried to fire her up and still the long hesitation. Aside from the codes and hesitation etc driving her seems normal.

Here are the codes i pulled up using bmwCarly:

Another side note since the Fuel pump seems to be finicky with this platform, i called up my local dealership to ask about the recall on the HPFP and they are saying that my vin number isn't covered. I thought there was a 10yr extended warranty on this?

[project jayden]

bump.

FWIW it looks like a bunch of unrelated electronic issues which may mean it is still battery related. Or battery cable (there was a recall), bad ground, something like that.

Just my initial thoughts, if they help in the slightest.

A couple years ago the relay that controls the radiator fan for the PPk2 went bad on my car and it severely drained the battery. The dash displayed all the symptoms you describe, and the car wouldn't start even though the radio and lights worked fine. I replaced the battery and while everything on the dash went back to normal, I discovered that the fan was running full blast. Once I tested and replaced the relay, the car was fine.

Hopefully it's just your battery and not a electrical short (like I had). And don't trust the little window on the battery. Mine was green when the battery was almost fully drained.

@tracer bullet

thanks for the reply. the battery relay cable recall was already performed on the car.

[project jayden]

Pig Farmer thank you for the reply. this might be the issue since I've already replaced the battery and I'm still having the issues. is there an easy way to find out which relay went bad?

[project jayden]

Pig Farmer can you please point me the way to where the relays are located? I was trying to find a diagram / location online but couldn't find anything unfortunately and I too am noticing the radiator blowing even on a cold start

On the PPK2 kit, the relay is on a bracket that attaches to the power steering fluid reservoir. It's the little black box with two wires attached to a terminal block on the left side of the photo.

The original fan relay is in the white ECU box located on the passenger side of the engine bay, which is under the black cover in the back. The fan relay is the little black relay on the right side of this photo with white numbers on it. It's hard to make out in the photo, but it looks like it says "99L/0++".

Pig Farmer you are awesome man Thank You Very much!!!

Update: Just in case anyone else is having similar issues (electrical malfunctions and TPMS inactive warning light) Check your RDC module. After checking all my relays and finding out they were good, i checked the RDC and found it submerged in water that had somehow puddled in the trunk. Unplugged it, dried everything off and the past couple of days everything seems back to normal minus the TPMS light since i'm still waiting for the replacement RDC to arrive.

[tracer bullet]

Crazy. Glad you fixed it.

Next up I guess you have to figure out why you have water there!

My wife's 328xiT had similar symptoms when the sunroof drains clogged allowed water to soak the tire pressure sensor module.

Pig Farmer. Mine 128i with 37,500km was averaging 7.9km/l and I entered a pothole at speed, the Check engine, ABS, brake light and DTC light came on and I took it to mine Mechanic. Diagnosis was carried out and I was told to change the rear left wheel ABS Speed sensor, the Ignition coil and Plug and do an alignment after. All this has been done with stock parts. When put under the OBD2 Machine with intent to clear the error, it was still giving the following codes, 94C2, 94C7 and 5DB6. I have not done the alignment yet. Please what are the meaning of the fault codes.

Came here to say this. I had this EXACT problem. Clutser going crazy, dashboard lights, etc. Turned out my RDC module got soaked.

I haven't replaced mine yet, so I'm running the car without it. Question though: Did your rear parking sensors (if you have them) stop working when you took the module out? Mine did and it's got me a bit worried.

Also, where'd you purchase your replacement module from?

febul I don't have the rear parking sensors unfortunately so i wouldn't be able to tell you.

I basically took the part number from the RDC box and did a search on ebay. Found it for around $250 shipped.

Hey please reply how did you resolve that issue? Thanks.

Rulz I did. check my response at the top. Turned out to be my RDC box was sitting in water and causing a short.

Thanks a lot for your input. Would you point me where is the rdc? I check the battery compartment and I couldn't find it. I have a 328i e90 2011.

I took apart the whole interior and double check must of the computer. The only thing I haven't check is the center console and the back of the cluster.

[brytom]

Seen that before. Water gets in the connector and messes with the K-CAN bus. After I fixed it, I taped the whole connector and portion of the RDC module in electrical tape to stop it from happening again. Haven't seen the car since.

[Rulz]

can someone show me a picture or video locating the rdc? i know is in the trunk but i dont see it!!

In my 135i it's located behind the carpet material in the trunk on the passenger's side.
