RichLV's UrS4

[RichLV]

My first rule is that no diesel shall be parked in my garage. I definitely want an S-car, since once in one, can't really sit in anything else. It has to be pre-2005, once over it, the taxes are a nightmare. Not really into the B-series anymore, kinda like the space. Basically leaves me with 2 options - C5 or a D2, maybe early D3. But there's a rule there - manual box only. I like turbos of course, but they tend to break down often, so swapping a turbo for displacement. Dunno what the MPG will be for the V8's, if I can manage around 15l\100km it would be cool.

Other problem is figuring out for how much to let go my 5-pot queen...

I've done loads of work on mine same as you, and it still finds a way to cause problems. I do agree, age starts to show and unless you put many thousands in in one gof unfortunately that's how they'll be.

I've considered everything from A8 V6 to MK1 Octavia 4x4 1.8T (awesome engine).

[RichLV]

Unfortunately I'm on the same boat. As much as I love mine, it breaking down or having problems on monthly bases is starting to get tiring and would like a car that I can spend time and money on making better not just keeping it going.

Tough with them huh? The age is kinda starting to catch up with them. Unless you strip down the whole car and do everything at once, it keeps breaking down.

I'm a bit heartbroken over this, I know that if I sell it, I'll regret it, since 5-pots are king.

I have a 2000 S8 with a manual box looming in the car ads...

Recently caught myself on thoughts of letting the car go. I'm kinda hooked on the S6 C5, have looked at a couple of examples but nothing exhilarating so far. I love this thing, but it constantly demands attention at the moment - steering rack leaking, coolant leaking, body needs repairs after the crash, fuel tank will start leaking soon, turbo started to drip oil into intake, etc.... I'm kinda in need of a very reliable daily, since I'm training 6 times a week in preparation for fights and don't have the time at all to address all this. Love the 5-pot and would like to keep it...

Just recently the clutch failed. Was an easy fix fortunately - slave cylinder bled the whole fluid reservoir onto the ground. Rode it without clutch to the maintenance place and replaced the slave cylinder with a Sachs unit.

[RichLV]

The fault is back. I was driving for the whole day and it was fine. Just in the evening I stopped at the house and let it idle for some time. CEL light on and the fault doesn't clear out. If I stop the engine and start it up again, it's gone but comes back after a while. If I start up and drive then there's no sign of the fault until I let it idle for a longer amount of time.

[RichLV]

Did you clear the codes after you first changed the ISV?

Yes. I let it idle for some time with the new ISV and the fault popped up. But then later I took a ride and it disappeared. Maybe the ECU re-learned the idle corrections... Will monitor during the week anyways.

[RichLV]

Idle started to jump up and down recently. Seems that the ISV was sticking like hell. I changed it and now the idle is fine, but I'm constantly getting a fault code:

00533 - Idle Speed Regulation
10-00 Adaptation Limit Not Reached

I'm combating this fault for some time already, but was thinking that the ISV change would help. Should I realign the TPS again?

[RichLV]

The swap is finalized. Oil cooling successfully routed into the front radiator.




The pipes are almost a straight fit. Problems only begin with the pipe which goes to the top of the radiator, as it's natural shape doesn't clear the electric fan area. We gently bent it in few places to fit and it's all in place now.

All I need now is a gear knob...

[RichLV]

I've finally swapped the old, broken up 5-speed box to a DSY 6-speed box from S4 B5. And the gearbox is fantastic. I like it very much, shorter mid range gears kinda make the car feel more lively, while the 6th is perfect for highway cruises.

The swap itself is a bolt on. Like, really bolt on. Everything fits, the only thing that needs to be taken care of is the oil cooling which for the first moment can be just connected together with a simple rubber hose. Of all the bolts that I used from the old box, only 2 did not fit, one is needed to be longer and other needs to be bigger. No grinding of the crank sensor bracket or the sensor bell housing was necessary. Swapped the oil to a Motul Gear 300 while I was at it and also readjusted the gearshift linkages (although it needs to be adjusted again, the shift is a bit wobbly). After more closely looking at the boxes, even the Procon-ten bracket could be swapped over, but it would only be held together with the 2 front bolts instead of 4.

I still need to finish the oil cooling. Yesterday I swapped the main radiator to Auto box one and I have the CMG box oil pipes. Hopefully the oil cooling will be routed into the radiator today.

I need a 6-speed gear knob now...

[hunker7]

Ah man, what happened?

[RichLV]

Yesterday was a sad day. Got rear-ended by my own GF driving my own backup car. I was driving the UrS and she was driving the 80. Stopped at a junction to let people pass and she rear-ended me. Seems fixable, but still sad. The UrS will live, but the 80 goes to the breakers... Going to the insurance guys tomorrow.



Today was a fun day though. Got a blast on the track, it was our local annual Audi Megameet. 300+ cars, drags, fast laps & lots of fun. Was kinda embarrassed going there with a banged up rear, but still had fun.

I was only trying to help. My 94 V8 S4 avant has a CMG 6 spd with oil pump and the lines go to the radiator. PN 4A0121251B. Somehow different than the V6 automatic one 251C.

No offense intended Dave. Utmost respect for you, sorry if it sounded like that.

This is what parts catalogue gives me for AAN auto radiator - 4A0121251C. The AAH (2.8 V6) auto radiator is listed as 4A0121251H, and it's NLA. And in 1994, it's 4A0121251M.

[UrS4boy]

I know Dave. I've read the DSY fitment comments like 20 times already. I want to go a little different route. I'll route the pipes into an OEM AAN automatic transmission front radiator using V8/AAN (auto) oil cooler pipes.
