Hi all, I have a 2.0 tsi. It was working ok but was getting the intake runner error so swapped out the intake. Now Key fob isn't working and have to open the door using the plastic key. If I use the plastic key no other door unlocks. I had to use the plastic key when entering the car to pop the hood to change intake.

Only certain electrics work, park lights, radio and we'll not a lot else. No dash lights, no mfd and definitely no start. Battery is 12.3v.

I have a ross tech cable it now can't communicate with any modules.

I've double checked the electrical connections that were unplugged when changing the intake and also checked engine bay and rhd driver's side fuses all appear to be ok.

The night before it died I happened to walk past the car and noticed all of the dash lights were on and thought....that's weird.

I've read a million posts about people with similar issues but still not having any luck.

Would really appreciate any assistance!

Thanks all
