Removing the UCH

[Gman]

Just a quick question.

How does the UCH come out? I've removed the 13mm bolt but it still feels solid, with the cage it's hard to see anything!!

I'm trying this as well, removed the 13 mm and also the one from fuse holder, still feels solid.

Need to remove it as I am checking everything as my imobiliser is on constantly.

Did you find an answer to this? I've changed mine today, and currently my replacement is wedged behind the dash as I couldn't get my old one out, really didn't want to start taking the dashboard apart!

once the 13mm bolt and the fuse box torque is out just pull it down. Its on a plastic clip of sorts

Ah so there's a torx to undo in the fuse box!

I could see how it slid down, but didn't want to pull too hard.

Thanks!

Yeah remove the far bottom left Torx behind the fuse box cover, Just a question, where did you get the replacement from and has it been coded?

 

[adamlstr]

BenTH - I bought 2 fobs, ecu, decoder ring and UCH all at the same time. I didn't just replace the UCH.

 

[BenTH]

Ah okay, How long did it take you to change it all over?

 

[adamlstr]

About an hour and a half, I haven't properly seated the UCH yet though.

I hope you got the chassis number from the vehicle it came from. As without it you won't be able to get replacement keys. Also the decoder ring isn't part of the matched set.

 

[adamlstr]

It was £40 for the lot, I'll just buy the same parts again rather than more expensive keys.

 

[Dan@SJM]

Well I suppose once you've replaced everything twice it would have paid for a key...

 

[BenTH]

Where did you get yours from? You get the same UCH and ECU numbers as your existing car?

 

[adamlstr]

Off here, from someone breaking another Cup.

Didn't know about the numbers until after, I figured all cups were the same.

 

[BenTH]

Guess you must of got the correct one then, or was it just one with the same engine code and Nx (N2 or N3) Number?

 

[adamlstr]

Luckily, both setups were N3.

Old thread bump but nobody mentioned a small tab on top of the unit. Once the 13mm boot and torx screw are out, push the UCH up to release the tab, then move it to the right before pulling down. Otherwise you’ll just snap the plastic tab. Ask me how I know 🤦🏻‍♂️
