Almost ready to pull the engine, but need some help please

[Osmosis]

I am almost ready to pull the engine on my 2.7t 2000 A6 quattro. From reading the Bently and watching a few good videos, I have a few questions.

First, I see what looks like an EGT sensor on the passengers side near the turbo. I don't have the heat shields off yet. Is there one on the drivers side, I would assume that there is one on each side. If so, where is it located?

Second, One of the video's tells about the importance of removing the vehicle speed sensor prior to engine removal. I have a manual TIP transmission. W
where is the vehicle speed sensor located. I"m following the wires on the rear fire wall, drivers side and I can't see it.

Third, Where do you hook up the chain to pull the engine? I have a black metal Loop on the drivers side that looks like all of the other hoist locations I"ve used in the past....but I can not find another hook/loop for the chain to attach to on the passengers rear or drivers rear?

Thank you for the help!

Oh, COME ON! 41 read & no replies, WTF? I need to know where to hook up the chain to pull this beotch out! Also, the video I watched was an OEM type video on pulling the engine on a b5 s4 and it was very specific to remove the vehicle speed sensor that was on the bell housing of the transmission or it would be damaged. On the bently, my speed sensor was near the CV shaft on the drivers side and on the top of the engine. Confusing as heck!

Found the EGT sensor on the drivers turbo and I think I do not have to pull it.

Best place to unhook turbo? at the turbo or at the clamp 6-8 inches towards the transmission? I assume the clamp, right?

Any help is appreciated!

The speed sensor is next to the driver's side output flange of the transaxle. You'll need to remove the driver's side heat shield above the CV axle to unplug the connector.

For the chain- both are on the inner side of the heads, near the intake manifold. One is at the front of the passenger's side head, the other is at the rear of the driver's side head.

Thank you for the responses! I have my CV joints removed along with heat flanges. I see the speed sensor near the front of the CV shaft. In the video I watched, it showed the speed sensor at the rear of the engine on the bell housing of the transmission on the left/drivers side. https://www.youtube.com/watch?v=YFm4utgahZM If you fast forward to the 12.24 mark, you will see what I"m talking about. Kind of confused as the car was a B5 S4, maybe it was a manual??? Either way, do I need to move the speed sensor when removing the engine? I've not found any such info in the Bently Manual yet. My car is a 2000 A6 TIP manual transmission....needs a new converter :(

Also, the rig to lift the engine is on the drivers side which makes me think that previously, someone was into the car and put the hardware on wrong. Wondering what my options are here to get this bad boy out?

One quick question regarding cat's. I've heard that you can gut the pre cat's and get some significant power increases. Will this cause any codes?

Thank you all for the help!

The speed sensor is on the bell housing, sounds like your talking about an abs sensor. if your taking the harness out with the motor, you dont need to remove the speed sensor until you pull the trans off.

the lift points are physically cast into the heads on both sides.driver side is on the back, passenger on the front

There are two sensors. The engine speed sensor and vehicle speed sensor. The engine speed sensor (aka crank sensor) is on top of the bell housing, towards the driver's side. There is one bolt holding it in place. The VSS is near the axle.

The engine chain holes are cast into the heads, so I'm not sure what you mean.

Must be the engine speed sensor I'm looking for. The video stresses the importance of removing it before you separate the engine from the transmission or you will destroy the sensor. I can't find it as of yet. Going to move some more wires when I get home from work tomorrow and find it.

The previous owner took the car to the dealer for services. From the looks of things, it looks like the previous mechanic may have removed the rear engine hoist support and put the front support on the drivers side. Guess I have to find where to purchase an engine support loop for the rear :(

Just one more thing to do. Speaking of "one more thing to do", I'm considering removing my pre cat's but there's not much room near the flex pipe to cut and leave room for a thick 4 inch band clamp...which means I will have to weld the pipe in place. I was hoping to use a 4 inch band clamps so I can easiy change out from the straight pipe to the pre cats if I sell her or if we move to where we have emission's testing. Also, If I do remove the pre cats, will I get a CEL? I have an APR stage 1 tune and have no desire to do any big mods other that rebuilding the engine to stock and that includes rebuilding the turbos. Considering using the O2 sensor sparkplug defowler trick if I do straight pipe or gut my pre cat's.

the engine lift attachment points are physically cast/machined into the heads man, I highly doubt the were removed.

attach engine lift here:

Thank you for the pic! If you look @ the front drivers side, there is a black loop looking device that I had on my Vett and Z28's. There was one on the front and rear which I used to lift my engines. on the Audi, only one and it's on teh front. You can see it if you look just above the drivers front intake. I assumed that was one attachment point. I'll be removing the electrical harness and inspecting soon...thank you!

I have a few more questions after searching many threads, I read that when you replace the timing belt, the crank lock sets the #3 piston @ TDC, not #1 piston, is this correct?

What concerns me is that I read a thread here of a guy who was unable to start his car because of the cam position sensor was not set correctly, or something like that. Another problem he may have been having is that the dual mass flywheel needs to be positioned at a specific position in reference to the crankshaft position sensor and I assume the motor needs to be @ TDC for the number 1 cylinder, not no. 3. I have NO experience with a dual mass fly wheel and a little confused about this whole project after reading a few threads. I would assume when changing out the timing belt, the #1 cylinder would be @ TDC which makes sense to me, but #3 @ TDC and the specific positioning of the dual mass fly wheel and the CPS, I'm a bit confused and a little intimidated. I plan on replacing my timing belt, water pump, thermostat and camshaft chain tensioners, in addition to new rings and depending upon plasti-gauge results, bottom end. I'm also looking for a rebuild kit for the alternator since I have her torn all apart.

I believe my A6 is a B5 S4, correct?

I'm not sure where to find my engine code number APB or which ever type engine I have. Where is this number located or is it the Vin number?

Here is the thread on audiworld that talks about marking the flex plate on page 4. http://www.audiworld.com/forums/a6-s...-pull-2871185/

Thanks everyone!

There is no "black loop" used to lift the engine- I'm not sure what you're referencing, but the picture in post #9 clearly shows both holes that should be used to lift the engine.

You are correct that cylinder #3 should be at TDC while doing the timing job, and that is when the crank lock pin will fit in.

In reference to your last comments, no- your A6 is not a B5 S4... It's a C5 A6. It does share the same APB engine with the B5 S4, however.

[brokenwrench]

The engine code is stamped into the front passenger hoist point. Based on your MY, it should be APB. The BEL engine began in 2002. And based on the info you provided, your vehicle is a C5 A6, not a B5 S4.

Thank you guys for the help! I really appreciate it! I am just a bit intimidated after reading that thread on audiworld and some confusion or lack of understanding of the dual mass fly wheel and CPS sensor. Once I pull the engine out & rebuild it, put the heads on. I my thoughts and plans are to then install cam's and tensioners with new pads, new timing belt, water pump and thermostat. I will have the engine @ TDC on cylinder no. 3 and then make two rotations of the crankshaft as in the manual. Once that is done, do I need to worry about the CPS and dual mass fly wheel, or do I just mark the fly wheel and crankshaft and put it on as I disassembled it? Also, Do I need to remove the CPS or just the vehicle speed sensor on the drivers side bell housing?

Thanks again everyone! C6 A6 :)

OK, I see where to put the chain now...Thank you!!! My prevoius cars including my Typhoon had two lift points on the intake front and back that looked like the single black one on the drivers side of my A6, hence my confusion. So I am using the circular hole's on the heads near the cam sensor, Passengers side front and Drivers side rear, correct.

Thanks again for that info!

Thank you everyone for the help! From referencing an Audi video, the vehicle speed sensor looks simple to find, but in fact, it is loacted below the turbo on the drivers side. Took me a while to find the darn thing, but now, its out. Now to remove the head shields, exhaust bolts to the turbo's, bell housing and converter. Hoping it will be out tomorrow.

Thanks again!
