Impressive! I'm looking to do similar soon, don't suppose you have a list of part numbers/prices?

Just made a new thread for everything listed.

Finally got some time to fix my rattling sunroof. Took the whole thing out along with the blind, gave everything a good clean, some silicone protector for the rubber seal and ptfe dry lube for the rails. Happy to say the rattle is gone, drove around the block for a bit and I can't hear the damn thing.

Just the dash rattling remains, between 1700-2200 RPM so you can ALWAYS hear it. I can't pinpoint it for the life of me, keep pressing around on every spot and it's to no effect. I'm gonna try and see if the side screws got loose or something, feel like putting an axe thru it already.

Had a very tired windscreen replaced.
No specific MOT fail damage but a plethora of tiny chips and scratches making it hazardous in the low winter sun.

2008 model with rain sensors , was a surprisingly decent quote for £245 without insurance (my 2010 TTS was nearer £600)...but my insurance agreed to cover it so it was £150 excess instead (no impact to NCB).

Ordered a replacement interior passenger door grab handle, and to my surprise the GTI now has parts classified as classic  so a longer waiting time with some mk5 parts now




Like new again

Found this today 

Welcome to the MK5 world :)) They all get that way and need sills replacement, rear fender fixing.. sometimes along with front fenders & rear boot lid (cheaper, no cutting and welding involved).

Been planning to retrofit cruise control to the GTI and finally did it today.

Hardest part was fitting the missing control wire with mine being a 2005 and missing it. I made and then added the missing control wire as people ask stupid money for it,  by ordering the different male and female pins to fit the connectors etc.....fitted and worked perfectly. I also got a secondhand stalk 1K0953513G off eBay for £13 and went ahead to fit. I already have the highline dash and modules so was sorted there. Coded it up and all works great  For the total cost of £30 in parts.

I am going to make up a few of the cruise control wires for retrofit purposes if there is interest.

I have a complete sill again  will address the correct fixings in summer!

After fitting my cruise control wire and stalk with coding, I made up a spare 5 retrofit  wires that I am going to sell on eBay

I also fitted some new seat lever badges as there appears to be a new style out these days

Old

New

Added a 10" screen for Android Auto and reverse camera, and a maglock phone charger to the car as I prefer the OE DAB headunit than the aftermarket HU's after trying them out over the years.  All works well

Acquired parts and loom made for fitting a washer fluid level sensor. I still have to tape and sleeve it, but good to go

Need to find some time to fit and code in

I have also bought the larger 5.5 litre reservoir to replace the current 3 litre one



UPDATE: Loom is now wrapped and shielded

Just waiting on the eBay 5.5litre reservoir

Took delivery of the 5.5 litre reservoir that is used with the headlight washer system. Weirdly this one came off a Seat Leon mk2 2010 without a headlight washer system or a level sensor, but all holes were there with factory bungs in which suits me fine. Pulled the level sensor bung out and fitted mine.

My GTI has the 10 speaker audio system not the usual 8, and the drivers side Mid was not always working unless the volume was cranked up.....then it came alive. 

It was not the wiring to the door as that must be fine as the tweeter and bass speakers were fine.

The Mid speaker was fine as all were replaced a couple of years ago so as a last resort I decided to swap out the factory crossover (the 10 wire, triangular module that the door have) and it worked





I have full sound now and it also sounds better, so the original must have failed.
