Cheers Baz I have 1K0 501 682 as the part for the proper cover, so 1K0 825 221 is its mirror image for the rear passenger side mount and N905 483 05 and N901 838 02 are the nut and bolt for the subframe.

But on top of that did the plastic nut that locates into the long threaded part from the subframe (1K0 501 682) have a nylon nut or something else in inside the plastic holder?

Correction...found it.

The OS bracket part# 1K0 581 682, as we know.
The NS bracket part# 1K0 581 681.
And you need 2 bolts Part# N905 483 05 and 2 nuts part# N 901 838 02.

The bracket part# 1K0 825 221 is used for the cover part# 1K0 825 206A which is that large cover by the exhaust pipe.

Regards.

Yeah saw that bracket its lower slung and has a thread rather than a threaded bolt to attach too, so the rear axle cover I have got and the plastic trim are mutually exclusive!  I have just received my heat-shield bits and bobs which is going to include some exhaust wrap and then some reflective heat-shield on the plastic itself  :party:

So does this cover os yours sit below or above the exhaust pipe?

Trying to find some under pics of a Golf MK6 underbody, to see how much more it covers.

Would be interesting to know if this cover and the larger cover part' 1K0 825 206 A, on the NS can be both fitted.

Regards.

I got the full undertray fitted by VW this week (£35.00).

I think everyone should consider this just for the increase in noise refinement (you are half-way to MK6 levels), actually VW should have fitted this from the start!

I will post again if I notice any change in MPG.

The cover sits below the exhaust pipe and the bracket fits in the same place as your current one so dont think you could have both on at the same time  :sad1:  but with the longer one you have going past the silencer not sure if this longer one would do much  extra will report back once fitted will be first weekend in September when Im back in glos with a drive and axle stands  :smiley:

Chaps,

Been reading this and it looks really interesting - especially the possible fuel saving benefits on longer runs.

Just one question, in the original post the technical diagram shows:-

"Bodenverkleidung" on each flank, is that part already on a Mk5 GTi (Ed30), so once you have the under engine cover and the rear axle 'parts' on that's it?

Or are the "Bodenverkleidung" x2 extra parts on this list.

Thanks

Is that not the floor undertrays which are standard?

This is what i understood but they lost me off when talking about the passat stuff  :ashamed: :ashamed: :ashamed:





Heres the list of parts i got with current UK prices.

Part numbers with RRP Prices exc VAT

Full VW Golf Engine under tray
(x1) 1K0 825 237 P Undertray £26.24
(x3) 1K0 825 951 Hex headed bolt (Combi) 80p each

#4 on picture = Rear axle cover as fitted to VW Golf bluemotion
(x1) 1K0 501 713 D Trim for Rear Axle £25.03
(x1) 1K0 501 682 Retaining bracket £1.67
(x1) N 905 483 05 Retaining bolt 47p
(x1) N 901 838 02 Retaining bolt £1.63

#2a & #2b on picture = Rear arm covers from Audi TT
(x1) 1K0 511 539 E Stone chip Guard £4.69
(x1) 1K0 511 540 C Stone Chip Guard £5.91
(x4) 8E0 825 267 A spreader rivet 10p each
(x2) 1K0 609 734 C brake cable clamp 76p each
(x2) N 102 854 02 Bolt 18p each




#3 on picture
1K0 825 206 A - Unterbodenverkleidung links hinten
N 909 707 02 - Schnappmutter 2 x
WHT 000 713 - Sechskantbundmutter (2 x ??)
1K0 825 221 - Winkel
N 905 483 03 - Sechskantbundschraube M8
N 901 838 02- Sechskantbundmutter selbstsichernd
N 908 338 01 - Spreizmutter

The only other thing on that list we were original talking about were 1a & 1b




I also bought the 1a and 1b larger deflectors, although based on ETKA I didnt get enough screws to fit both as at the moment I only have the one installed but as the profile picture shows it almost has a significant increase in air deflection.  It needs some more fixings as I didnt order the right parts  :laugh:

#1a & 1b  i think are the 'all terrain protection'
1k0 825 001 b
1k0 825 002 b



Anyone had a good look under a current bluemotion golf yet just to see if theres anything we have missed?  :smiley:

The parts on the current large cover alomg both sides that bits 1a and 1b fit over, on the MK6 golf have little castle shaped cut outs almost like a mini diffusor on each side.

If that makes sense. If the rep at wok comes in with his BlueMotion Golf Variant I'll try and take some pics.

I have a mk6 golf and this is why i did not get 1a & 1b mine are like this.



I was wondering if there was any other covers under the bluemotion golf apart from the rear axle one we know about. Maybe some on the ends of the rear bumper to smooth that void out?

I've not seem anything listed for the Golf, however there is a right rear cover for the Golf Variant and Jetta.
Part# 1K5 825 205 B, you may be able to adapt this to cover any void on the drivers side rear around the rear bumper if thats what you mean?

So I'm still a bit confused as to whether the two underfloor flanks are requiring the left and right sided "bodenverkleidung" from the original post on this topic and then you add the 1a and 1b parts on top.
Are these standard fit on Mk5 Gti's?

It looks like a good add on to me, along with the bigger under engine cover and rear parts, but wonder if others had fitted these? And if so what parts/numbers are these?

That said I'm no Adrian Newey regarding airflow..

Taken from an earlier post:




Nr.1 und (1) are mor kind of ''all terrain protection'':




2a and 2b comes from Audi A3 and TT 8J (fwd only).

Nr.3 comes from TDI BlueMotion and is best to be used with an non-resonated exhaust.
Nr.4 is ''Hinterachsverkleidung'' from TDI Blue Motion.

You would need 2a,2b, 3, 4

1a,1b are part of a rough road package, 3,4 are from the Blue Motion Golf
