ZHP cluster replacement

[usinjin]

My instrument cluster is starting to go. It started with the turn signals, I thought they were unoperational due to no indicator sound/no light on the cluster, but the external signals do function. Cluster also dims during the day as if the lights are on when they aren't, show doors being open after they've been closed, etc. I would leave it as the dials still function but I'm worried it might not always illuminate at night.

I found DIY instructions for recoding/swapping VIN and mileage over to a new cluster, etc, seems relatively straightforward. My question is, can the new cluster be a regular 325/330 cluster if I swap the dials over from mine, or is the PCB also different somehow on the ZHP from the standard 330? RealOEM shows different part numbers of course but I'm not sure if that's just because of a visual difference with red needles/silver rings/redline marker. Thanks.

I don't have the answer. But there's this recent arrival to LKQ in case you want to grab its cluster. Looks like the price is around $30 :

You are always on top of these inventories my friend! For that price, might be worth picking up and trying.

You bet. They also have this 2002 325i:

With the cluster completely disassembled you can mix and match parts to your hearts desire.

The issue is the eeprom on the board. You could pull it from the old board and install it on the new board and that would require no coding/programming. But unless you are well versed in soldering on circuit boards this may be a bit of a challenge. If you got another cluster you would still have to disassemble, clear the chip and then program it. Both options aren't to hard but do require a little bit of extra knowledge/experience in their respective repairs.

Perfect, thanks George. Exactly the info I was looking for!

I'd figured out the how (for the most part) of the coding/swapping EEPROMs, but wasn't sure if I could do so with a board from a regular e46. Sounds like it does work.

Thankfully, I do have a scope, hot air station, plenty of USA-made flux and a few years of SMD rework experience, so I think I'll give that a shot!

If it doesn't work out, bring it up to me in Cedar Park and I can clear the chip for you. You'd just have to program the cluster, but it's an easy second option.
