All in the Wiki

Cheers mate, will give it a go.

As above, I made the silly mistake of buying a blue point reset tool before reading the Wiki

[polsta]

a small piece of wire in a folded bit of paper with the below drawn/printed on , marking the holes, is all you need kept in the tool kit

Unfortunately didnt work. Will pop it down to the local garage and get them to do it. Cheers for the help.

Where are you based?

If you're absolutely sure you did it correctly, and it didn't work, then your SI Batteries are knackered. A garage will be unable to turn off the lights if they don't swap those batteries.

Based in Portsmouth Chris.

Def did it right, placed a elctrical wire in the correct hole and tried with earthing it to the car and also in hole 19. When i turn on the ignition all the lights go on and the inspection light goes off but as soon as i start theh engine it reverts back to the inspection light been on. I take it you do turn the ignition on so you get the lights on the dashboard rather than just the first turn of the key.

Im guessing SI batteries are exspensive and hard to replace!!!

[Chris_B86]

Ah never mind, was just going to say if you're local you could have used my reset tool

Expensive if you pay someone else to do it, yes, because they'll inevitably break something else.

Have a read of this, and then click on the guide to replacing the batteries:

No worries Chris, Thanks anyway.

WIll have a read Grr, thanks for the help.

where in pompey are you mate im in the area ?

you just bridge the 2 said holes with a bit of speaker wire, cut say a 4 or 5 inch bit, strip 1.5 inch from each end, and fold the bare bits a few times, so you get 2 nice thick ends that contact properly , connet the 2 holes and turn the ignition (not starting the car)

what year is the car ?

ive never replaced them, but may be easier is to just buy a new set of clocks (£15-20) with known good ones in, then swap your dials and bits around from yours

[Llewekab]

Over in Fareham Polsta. Gonna go and give it another go. Can't see why it's not working.

[Llewekab]

Tried again and failed. Will just have to learn to love the red light.

[polsta]

are you definatly gettng the right holes and its connecting ? and leaving key turned for 30 seconds say to ensure ?

also, are you certain its the inspection or oil light on ? and not something like the red brake sensor light ?

Tried again and failed. Will just have to learn to love the red light.

If the SI board batteries have failed, they will soon start to leak corrosive liquid over the copper tracks of the SI circuit board, rendering it unrepairable. This circuit board carries all the electronics for the other gauges, etc., except the speedo, so soon you'll have more problems than a red light!
Get the cluster out and opened up. Batteries are easy to replace if you know how to work a soldering iron.

brian out of interest- if my clocks have been out the car and un-used for over a year stored in a garage, would the batteries still be ok ?

[Brianmoooore]

Should be OK if the batteries are good. If the batteries are the NiCd type they should soon top up their charge when reconnected, but the Lithium type is not rechargeable and is being 'used up' for every minute it's disconnected from the main car battery. Their total life is a few years, but there's a wire link on the board that should be snipped if storing these boards for any length of time. BMW replacement boards have a couple of pins with a plug that connects them together instead of the wire link, so on these you just pull the plug.

Didnt work on mine at first . I earthed direct to the battery and worked .

[polsta]

i see thanks as always, im not sure what mine are,i think the latter , although i do have a few clusters i should dig them out, how much roughly is the replacement board out of interest ? does it have new batteries on it too ?
