Weekend DIY

[Other_Erik]

So this weekend I'm planning to take the gloves off (literally, since it's supposed to hit 60F on Saturday) and do a bit of work:

Suction Jet Pump
SAI Delete / Block-off
Power Steering Fluid replacement
Coolant top-up
Air filter clean and oil
Cabin air filter replacement
Windshield wiper replacement

I'm gathering necessary components and don't have my trusty Bentley manual on hand - what size(s) of vac lines will I be needing if I want to replace stock line? Mainly looking at the SJP lines and putting a new loop on the SAI sensor so it quits bitching about insufficient flow, but if I'm already in there, I'll probably end up replacing anything I can get my grubby little hands on.

While I'm in there, I'll also take a look around and see if anything looks out of place - After-Run-Pump being a suspect for age / wear-and-tear. Hopefully will be able to walk away after this weekend with no CEL (SAI insufficient flow), and next step will be EGT Sensor replacement made much easier by SAI Delete...

TIA

The intake r&r is not for the average diy weekend project.

Replace the ARP always. I just used the last one in the country.

Intake gaskets, injector o rings, bypass tube o rings are all a must if the intake is coming off..

Imho

Any suggestions on part numbers? If you just snagged the last ARP in the country, is gonna be hard for me to source a replacement...

Thanks

Is it 034965561C? Same pump as on the URS4?

Replacement/relocation of SJP was a solid 8hrs on my end which was a tad high given I had never removed the intake as part of any repair priorhand. This repair certainly isn't for the faint of heart as it necessitates good recall and organization as you remove the entire wiring harness and set it to the side. I think that anyone that has indepth mechanical experience, all the right tools, and all the right knowhow, can perform this work in a solid 6 hours from start to finish once they have done it at least once before.

easier with the engine out

I agree with the times completely.

Im making plans for the other cars as i know the ARP needs replaced on most every RS6 out there.

Are we talking about the Additional Waterpump, 077121599A. If so FCP say they have it in stock, not cheap at $362. And ECS says ships in 2 days but I've found they lie about that a lot.

Thanks for the part number, I see there's a possibility of replacing with a relocation kit, VAG part # 078998998
Anyone have experience with this? Most of what I see is re: relocating the pump on 2.7tt from under the intake to somewhere more accessible, question is: will it work? Do we even have a space to put this in? If I were to adapt this kit to be inline instead of relocating, would there be any problem? Would sure be nice to get this at ~$170 instead of the lowest price I've been able to find on 077121599A being ~$340, and nobody having it in stock...

Thanks

Okay, so a solid weekend of 12-hour days on this. Got it. Probably not gonna happen til next weekend in that case, but it's good to know.

Readiness checklist:
Good recall and organization skills - check and double-check, the wife will be working this with me and she is meticulous.
indepth mechanical experience - check, though not with this engine, that's why I'm asking about specifics with the BCY.
all the right tools - probably - Are we talking simple hand tools (triple-squares, sockets, hex and star bits, etc...)? Or is there some VAG-specific one that I'm going to be F***ed trying to find?
Knowhow - that's why I'm here, benefitting from the experience of those who've gone before me.

Anyway, on order at the moment:
Intake Manifold gasket set (arriving today)
SJP - arrived last night
Silicone vac line kit - arrived last night
1Gal BND concentrated coolant (arriving Saturday)
1 BND PS Flush and Fill kit (Saturday)
1qt Aces IV (Saturday)
16 Injector O-Rings (Saturday)
SAI Block-off Plates (Saturday)
2 Trunk support struts (Saturday) obv not connected, but mine need replacement and I'm already looking at spending quite a bit of time on her this weekend anyway...

Also have lots of engine de-greaser and other such ready to rock because I know it's gonna be filthy. Last major (autopsy table / intake off) service on this engine was 5 years / 37k miles ago. Don't worry, the full TB service was done 9k miles / 2 years ago.

Can anyone think of anything else I should do preventative-maintenance-wise while I've got the intake off? I saw a comment re: bypass tube O-Rings - when searching that all I can come up with is the A/C Condenser tube, and I'm guessing that's not what DHall1's talking about.

Waiting for the local stealership to open so I can talk to their parts advisor. It's nice and not nice at the same time to have the guy at the parts department know me by name... I'll be asking him whether the A6/S6/Allroad pump (078 121 601B) is identical/equivalent to the pump included in the RS6 pump KIT listed as part (077 121 599A) - I'm guessing the difference between the two part numbers is the listed RS6 part includes the rubber mount, metal strap, hex head bolt, and mounting plate, which should still be in fine shape given they're tucked under the UIM.

More to come on this, hopefully this means my weekend DIY will be able to happen next weekend instead of whenever someone from Germany realizes I'm telling them to shut up and take my money

You only need 8 injector o rings

Pn for the bypass tubes
N-908-325-01
You need 2

Big thanks to Aronis for finding the part number on his ARP (helps that he's got his engine apart at the moment)

The pump itself is Audi PN 078121601F - I ordered up revision B (or 078121601B) to keep me going for hopefully another 12 years 4 months 19 days.
$99 for a brand new unit, made by Pierburg

Sorry it took an extra week, the engine was up side down last Monday.

[DHall1]

Veddy interesting. Was this ordered thru Audi?
