Hi.
Based on my initial intro post, where I have outlined the work I have in front of me to get my A2 up to scratch, these posts describe each repair or upgrade.
1. CCU replacement due to Central locking cycling.
I had hoped that the CCU was the cause of not only the cycling, but also the fuel flap and drivers electric window, but things are never that simple!
I have an older A2, so the CCU needs to be an early suffix to ensure the key remotes still operate at the right frequency. Mine was a Q suffix so I found on ebay an 8Z0959433Q CCU from a 1.4 TDI. It had broken plastic around the clip area, so was cheap at £54.95 incl freight. It was a gamble.

it appeared to be a simple process to replace this (and it was), although I was not sure if I needed to disconnect the battery first. As this was not mentioned (and his videos are so thorough, it would have been), I assumed not and went ahead without disconnecting.
The unit worked immediately, and all I had to do was use VCDS lite to check the coding and other aspects as described by MtlCarGarage again, here in part 2
It was important to check the additional items, as my replacement CCU was not coded for Air Con, which may have been tricky when it gets hot.....
I got the key coded straight away, and everything else appears to be fine, so a good success. No cycling, but no fix for the other issues I have (fuel flap etc), which upon furthe VCDS investigation, were not CCU caused anyway (assume micro switch in drivers lock - refer to post Repair 2. when I put it up).
The broken connector area was not an issue, nor do I believe it will become one. The TDI source also does not appear to be important, as the interior kit is all the same.
Let's see how long it lasts........
Cheers
Matt
