Instrument cluster not universal?

[TonyWilson]

My rev counter goes crazy when i put the boot down, it goes off the counter then starts to swing back and forth probably wondering how a 1.6 litre can accelerate the way it does lol.

Does this mean i need to get an instrument cluster from a 325?

There is a coding plug fitted to clusters. you need to swap it for the one that is in your old cluster.

[Ziggy]

Nope, just the coding plug

[12345kevin]

presumably the cluster is from a 4 cylinder car and you have a 6 cylinder car ? If this is the case you'll just need the coding plug that goes in the front of the cluster

[Ziggy]

Think that covers it?!

[dazleeds]

if your cluster has a code plug in the front then you should only need to change the plug

if your cluster dosent then yes youll need the full cluster afaik

Lets all post together

hope that helps

Unanamous verdict lmao, thats what i love about this site quick response and with the correct answer.

Yes your correct i've gone from a 4 clinder to a 6 cylinder but i never got any coding plug so i might have to steal one lol

Cheers guys

What one is the coding plug?

[Chris00]

So the old ones and the new ones arnt interchangeable? What abot the fuel guage coding plug? ive got a cluster out of a S.A e30 with the long range fuel tank and the guage reads the wrong amount compared to the U.K guage

my guages used to read slightly fast when i stuck in my 4 pot conversion . other than that there was no jumping around or erratic reading.

Exactly! With the wrong coding plug, the readings should simply be wrong, not erratic.
