Evening gents,

First time posting on here.

I currently have a 2005 TT (AUQ) FWD, which two days before returning back to work has decided to start then cut out with no reading of the ODO. The rest of the cluster works fine just no signal on either the left or right hand screen. I think it’s the immobiliser which has failed. I have tried to send the cluster off for repair but apparently it can not be repaired... (typical). I am now looking for a replacement cluster.

My question is to you ladies and gents, if I find a used cluster with a matching part number will that work on my car or does it also have to be from the same engine code too??

I also have a 225 BAM TT which I am currently restoring, I presume this cluster won’t run the AUQ?

Thanks in advance

Hi, Welcome to the TTF.
I'm surprised the immobiliser cannot be coded out as that is usually the cure.
A replacement has to be coded to the ECU & C/L. It can be done be special software & tools are required.
I don't know who you used for the failed repair but here is a list of repairers who have been used.Perhaps one is local to you.

Hoggy.

Quite likely that it is the back lighting that has failed rather than the screens themselves. Try shining a torch at them or looking at them from an angle and you may be able to see the digits faintly. Back lights are a fairly easy repair if SMD devices are within your compass and a piece of cake for professional repairers. Did you actually send it to someone for assessment?

Swapping clusters is quite difficult. You should be able to find several posts on the subject. I understand VAG Tacho is the preferred method of obtaining the PIN from the new cluster and car; and VCDS the preferred method of coding the cluster to the car. Or (as suggested) you code go dowm the immobiliser defeat route.

Incidently does anyone know if a non-working Odo is an MoT failure these days?

There's also the issue of the late 2001 clusters having reversed gauge polarity, so making them work on an older car is an absolute swine; make sure the replacement cluster is period to the car it's coming out of.

Thanks for all the info gents.

I sent it my cluster off to Ecu testing in Ripley (Derby) but as I mentioned before they quoted it is not repairable. I found there link through eBay and seemed like that had great feedback.

My friend has got a couple of clusters that I can try, he also has a Vagcom diagnostic tool which I will try and code. I have a feeling they are from older vehicles but will try and see what happens.

Worse fails I will try some of the links that Hoggy has posted so thanks for that. Thanks for the hint with the torch too I will try that this afternoon as I have just had the cluster returned today so will give it a go. If all fails looks like I will be breaking it lol...

I appreciate all of your responses and will be recommending this forum to a few of my pals.

In order to code the cluster to the immobiliser you need the PIN codes for both the car and the replacement cluster. VCDS cannot read these codes. I have read a used cluster PIN code with VAG Tacho but there are other tools that will do it.
