E46 Cluster was reading "PPPPP" now reads "999,999" - Recode advice required.

Hi guys! Firstly thanks for having me, I own few BMW's including this E46 I'm having issues with..

I've had this 52 plate (5 speed) 330Ci for almost a year now but it's been parked up a good few months as I've had an issue with the cluster. After the car was sat and went dead the cluster showed a “PPPPP” error upon charging and being started back up. The rev counter, speedo, fuel and water temp gauges all still worked however it seemed the speedo is also now over reading. Says I'm doing 60 when I'm actually doing about 45?

I purchased a cable and installed NCS Expert. I had a go at re-coding the cluster based on some advice I received but had no luck and kept getting errors.

On someone else's advice I tried to discharge the system by touching the positive and negative battery cable terminals together for 30s (obviously with the battery disconnected), since then the “PPPPP” error has gone and the mileage now displays 999,999. I haven't driven it since and ideally would like to return the mileage to the correct number as well as sort out the ABS light which was never lit before.

Can anyone advise on what to do before I contact BMW directly? I'm quite tech savvy and happy to buy cables / recode if instructed correctly.

Thanks in advance!

I would say the cluster was dead. If this wasn't caused by coding in the first place then I would assume the EEPROM is kaput.

New cluster - PA Soft to write the VIN, coding and mileage to the new cluster and that should solve all of your issues.

I ended up swapping out the cluster for one on very similar milage to the original, I have a tamper dot now but at least the milage displays again. Not exactly a win but not exactly a loss either.

PA Soft can write the correct VIN and mileage IIRC
