Update 4SD4 campaign

[jrc193]

My Mk 7 GTI PP DSG has just undergone an update under the above campaign , which apparently affects, amongst other things the hand brake and ,interestingly the front wheel differentials . Anybody able to through any light on what is involved and why the update was necessary please? Thanks

No update appears to be available for mine. Might be just depending on BW.

I had the update a few weeks back.  No idea what the issue was but all I know is now my handbrake is now much quieter and smoother in operation.

I have just got my GTI performance back from its first service and it has had a recall applied, does not say why but the details are:

Carried out workshop action
45D4 2014-04-02 S-Golf service measure 03
V000 010 006           C03C1A Sticker
V04L 130 235 G        C03K3A Pipe

I know any sticker fitted by a master tech must be worth 10bhp but does anyone know what Pipe was changed and why - the garage is not too forthcoming.

Thanks

"On 02.04.2014 VW launched action number 45D4 for 1.2 tsi and 1.4 tsi Golf 7 which is about upgrading the software in the ECU (engine management software), plus recoding and updating computers in the front doors (related to confort computers responsible for opening and closing doors and windows) and the EPB (electronic parking brakes, including dissengagement of Auto Hold); there is also some more recoding for the GTI 2.0tfsi models"

Interesting but the replacement of a 'Pipe' indicates something other than a simple recoding, any info on the 'more GTI coding ' and what it was for?
