Back together after engine out

[Brav]

I know it has been a long time, and my plans have changed from the original 6 speed project.. so I decided to start a new thread for the assembly.

She is back together, and have most of the kinks ironed out. Was difficult to remember the routing of wires and such, and next time I will do a better job at documenting parts as I remove them (i.e., screws). Here are some photos of the process.

here is the front end. did all timing components, new pump, and new front crank seal. You can see the build up from the crank seal.. after 175k, it was time.

Waterpump was also leaking.

Before and after Buffkin pipe. YEA I think I got 99.9999% of the useful life out of the old part! Everyone must do this for any engine-out work.

Top end, seems happy for 175k

Cleaning up valve covers and other components. Small amount of sludge, but mostly dirty due to leaking covers. Had never been replaced since I've owned the car :D

Back together with rebuilt turbos and new engine mounts.

My solution for properly sealing the leaking caps of the aux radiator plumbing. Pinch welded via TIG - thanking my buddy at a local shop for this.

Wagner hose was too long - and pinching itself in the middle. had to hack saw it down a bit to fit right

I broke in the rebuild turbos from Midwest Turbo as they prescribed. After the oil change, the car has felt very sluggish.

From the ABS group, I got the intermittent gear recognition signal code (01119) and freaked out, thinking it was the trans, but turned out to be wheel speed sensors that were quite dirty. cleaned all 4, and hasn't come back.

From the Trans group, all has been good, zero codes until today - 17095 - Transmission fluid temp sensor (G93) - implausible signal, intermittent. (??) Anyone have this before?

From the ECU - the only code I get is 16716 - Knock Sensor 2 (G66) - P0332 -002 - signal too low. I clear this and it comes back every time.

Today I finally logged the measuring blocks for the knock sensors - all are around 0.8 or so at idle, and go up to 1.5-2.5 when engine revs.. EXCEPT for the two on cylinders 5 and 6. Both of these read a steady 0.234v at all times, not a flinch.

I did a road test log, see below. All looks well, except boost was slightly low on first pull, and more low on second pull. Lamdas look good to me. But lo and behold, look at the timing!! pulling to -8 to -9 in high RPM. I could only do a second gear pull due to traffic, but I think this is good evidence of the symptom/problem.

So is my faulty/(unplugged?) knock sensor the cause of the timing being pulled? Where is G66? Please tell me I have to pull the motor to get to it. I have absolutely nothing more I would rather do than that.

Wow....nice work Brav. I am right behind you and also had the turbos rebuilt @ Midwest. I talked with Dan there and got the go ahead to use synthetic oil during the break in. I just need to limit boost for an extra 100 miles or so. Unfortunately I can't help with the logs, but you know there will be many who can. Good luck!

[905084]

I had the same problem with the Wag hoses.....too long but dealt with them.. :/ I still haven't changed the oil from my rebuild with the Midwest Turbos (3k in) and I love them.....flogged Thing 2 today hard and god I love it!!

[lswing]

Replace that G93 temp sensor ASAP, it can cause errors in your TC locking. I can send you an email with instructions and pictures, imagine sensor is cheap but got mine for free.

Boost looks fine. Are your logs screwed up or is that negative timing?

Logs are unfortunately correct. You can see, the time it took to get from 2500 rpm to 5500 rpm was nearly 3 seconds. Eternal. 2nd gear pull in this thing was blistering before.

Yes, please send the email, would be helpful!

[lswing]

Will dig it up, direct from Tozo. Gotta drop pan, but sensor is easy to get to, in vb wiring. Option before that is check connection at trans, can get crusty.

So that negative timing is screwed up. How is the ecu not checking that? Whenever I've hit negative, when my tune was off, ecu would pull boost, and timing would jump back positive. Running good I am at around 25-35 timing, then down to 8-12 under full boost, never negative. Something wrong with timing belt job maybe?

Could be. but the car runs normal and smooth under under high load. Timing is normal when cruising, 25-35 as you state. Cam phase adjustors seem to be working correctly. The only correlation is with the knock sensor code/voltages... when cruising, they are all low. then under load, they all rise but two, so sending an implausible single maybe, and pulling all timing?

[lswing]

Sure somebody that knows more will chime in, never seen a timing pull like that, sounds like you might be thinking in the right direction....

[4everRS]

That timing is not right. My guess is those knock sensors are screwing it up.

Nice shop you've got to work in there

[905084]

How did you do the timing belt?

[hahnmgh63]

No help in determining which sensor but a related thread. Notice where he say's it is pulling his timing.
http://www.rs6.com/showthread.php/23581-Anyone-replaced-a-G61-knock-Sensor?highlight=knock+sensor
Anyone have access to Elsawin? My old computer died and I was told it wouldn't load up on Win7.
P.S. never had a code on the tranny, I would try the electrical plugs first, contact cleaner (pro-gold, Stabiliant 44) and re-attach.

[lswing]

G93 trans temp sensor, little orange guy mixed into VB wiring. Here are a few additional images to help. Cut wiring and solder in new one, been fine for months now.

[Brav]

How did you do the timing belt?

with a VAG timing bar, markings, the whole bit. Had a dealer tech help me out on that part since he had the tools.

[905084]

Pin the crank too I assume.....so that leaves out the mechanical....on to the sensors....

[hahnmgh63]

Can you post a log of the knock sensors Block 20 & 21 along with Block 3 (timing). Together they should tell if "sensed knock" and the timing pull are occurring together.
http://www.ross-tech.com/vag-com/m_blocks/

[milka]

If you want to check your cam timing, do a quick log of block 93.

You should start using me7logger, you can monitor >70 metrics at more than 15 times/sec

[Brav]

Pin the crank too I assume.....so that leaves out the mechanical....on to the sensors....

Yes, crank was pinned. Will do logs shortly and report back.

Does that orange wire show in the first pic? I am familiar with the valve body to some extent, but have never seen that little guy

Yep, I marked up the pic....

Okey Dokey..

So, ignition timing seems completely normal while lightly accelerating and coasting. Hovers around 25-30 at cruise, 40-50 at 3k RPM when stopped, and close to 5 when on decel. Only when under heavy load does it drop like a rock.

lswing, your requested block 93 is here (bottom row)
http://i49.photobucket.com/albums/f282/ckreidel/Audi%20RS6/IMAG5660_zpsfog3svjd.jpg

The camshaft adjustment is off at idle, and comes on and stays on during tip in, cruise, and acceleration. seems normal. when adjustment status is on, each bank adjustment goes to +21*KW or so. binary, on or off. no inbetween

The block 93, started out with bank 1 at -10*KW and bank 2 at -4*KW, but after warming up changed to the above levels, and never moved, no matter what state the engine was in.

Below, we see the system failed the knock sensor test.. and you can see voltage at 5 and 6 at the .234 as stated, while all other cylinders varied with RPM/load.

[Brav]

Mark, here is your requested log.. short 3rd gear pull. we can see that ignition timing pull is progressively decreasing, not in line with timing retardation by cylinder. pretty much right when i give it partial throttle, all cylinders peg at 15.8 for retardation.

Another log of knock voltage per cylinder and timing, for funsies

I think this seals the deal for the sensor.. so where is it? impossible to have cyl 5 and 6 be 100% inactive

OKAY. I feel like an idiot, once again. Found the problem - crushed/cut wire to sensor. not quite sure how it happened.. can probably repair it, don't really feel like pulling the intake manifold. I'm 99.9% sure this will take care of the power issue. Will report back once done. Thank you all again for helping.

[hahnmgh63]

Congrats on the find. Get it fixed and the fun can begin.

Thanks. Hopefully this will help someone in the future.

[milka]

Good work, well done I really hope this fixes your problem. I know what it's like to finally put the engine back in after 6-12months pulled apart and then looking at all the pics to try and figure out where everything goes.

P.S. block 93 shows that the timing is a bit out of wack between the 2 banks but not enough for it to be a problem, they will get further out over time but nothing to worry about unless it throws a code.

[Other_Erik]

Wishing I had a proper garage to pull off this big of a job. Glad you (hopefully) found your issue.

Personally not looking forward to the 5-digit parts & labor bill I know is on its way when I decide to do a full button-up maintenance :\

Yea, I noticed that the phase was out of wack when I had first ever logged that block. Its about exactly where it was after the recent tbelt.. at least its consistently wrong! Maybe I can address it next time, but I would be afraid of making it worse.

Fixed the wiring over the weekend. Re-soldered all 3 wires to the knock sensor. another problem was the plug, it had a crack in the flange, so it wouldn't always click all the way in if wires were tugging on it. All sorted out now, runs like a bat out of hell!!

Nice! Should be there soon myself. You ever get the temp sensor fixed?

Good deal. I'm not sure it's what caused my new trans to fail in 8 months, but it was the only code or issue that's shown up. Maybe we'll find something more upon tearing the broken one apart. What I found repeatedly in searches on the issue was belief it causes issues with the TC not locking up at the right time, therefore transferring too much power or staying open and cooking the fluid, then cooking the clutches.

did you do oem turbo rebuild?

More or less, yes.

G93 trans temp sensor, little orange guy mixed into VB wiring. Here are a few additional images to help. Cut wiring and solder in new one, been fine for months now.

Do you have a PN for this? Cant seem to find it in ETKA, just PN for whole VB harness.

I do not, Tozo had an extra used one that he sent over. Maybe check with him if nothing comes up?

Ok, more fun and games. Bumping this for the Transmission Fluid Temp Sensor G93. The little gremlin decided to show up today on a scan. Same code as from my previous trans where we replaced the sensor during a fluid change and the code was gone.

So so now it's back with a new trans. Leads me to think its a wiring issue from the trans to TCU. Can't imagine this sensor would fail twice on me, when they hardly ever fail, it's a simple sensor.

Ideas? I'm not driving the car hard at all this year, and will keep a close eye on it.
