Speedo swap a couple of things.

[glenpring]

Just got a second had speedo. Got it all working in my car but 2 things first the temperature of the water is fine but there is a red light and it beeps any thoughts? I doesn't do that on my original speedo. Also I need my speedo mileage change my speedo reads just over 90k and the second hand one reads just over 108k can anyone help or point me in the right direction.

Have you swapped in a 6 dial or 4 dial cluster?

 

[glenpring]

I have 6 and the new one is 6 like for like same car

 

[Badger]

Did you get it with a warranty it?

It sounds like your new cluster has the same dry solder issue which (I'm guessing) you had with your old cluster.

To answer your question with the mileage, it can be changed with VAG Commander / VAG Tacho.

When I had the dry solder last time the gauge didn't work and I got the red light and the beep. Now with the second hand speedo it just beeps and red light flashes but the gauge works.

If you have VCDS scan the car and see if the Coolant temperature sensor is working correctly. If it is, then you could of had a stoke of bad luck with another faulty cluster with the same issue.

Just found this page on here.

If that's a similar diagram to my speedo it looks like there is a dedicated pin just for the red light/buzzer do you think 1 pin could have dry solder, because everything else seems to work properly?

Three options that I can think off:

1 - Check the pins in the connector blocks that connect to the cluster to make sure there are no breaks etc...

2 - Get a VCDS scan to see if there are any other issues such as wiring to Coolant sensor or faulty Coolant Sensor

2 - Get the cluster solders re-flowed to remove the dry solder issue.

i have vag com lite but i think there is a problem with it because i can connect to the car but cant get all fault codes and says something like to busy or something like that. is that just because it lite version if it is ill by a cheap copy off ebay for the moment till i save for the full version.

 

[Badger]

Lite should read all error codes, some functions like adaptions and coding are restricted.

when i get in ill take a screen shot of what comes up maybe im doing something wrong.
just looking up online for speedo correction software and the all say for vdo but i think my speedo is trw and cant find anything for vdo.

i think the error message i get is "too many communication errors to continue"

Is the red light and beeping to tell you the coolant level in the expansion tank is low (or the sensor's unplugged/faulty) like on the Leons ?

 

[glenpring]

I put the old speedo back in and there is no red light or beeping

 

[Badger]

Looks like another set of dodgy clusters!

 

[glenpring]

When you say dodgy what's the common fault?

 

[Badger]

The 6 dial clusters are common to have dry solder joints at the connector blocks causing erratic behaviour. Most people swap in the 4 dials from the later FR models which are better.

 

[glenpring]

if its just the solder ill re flow and see what the outcome is. don't suppose you know what that error messages means when im trying to use ross-tech lite i wanna get the full version but don't wanna spend the money till i get the lite working.

The cable may not be setup correctly, pop over to the VCDS section for some hints and tips

 

[glenpring]

i got the cable detected and can use it on a few things but cant scan for faults or erase them.
