A big thanks goes to Modified A4!

From some reason the o-ring that ETKA lists isn't correct....it's too big. I would suggest trying this o-ring: N 903 168 02

I took it out for a spin and it worked great, came on as it should. I'm not sure the thermoswitch operates exactly how I thought; but I know it closes above 93C, so it works really well for what is needed.

The thermo-switch I pulled out was:
078 919 369

I checked and this sensor was superceaded by:
357 919 369F.

Thanks again to Modified A4 for finding the part number and everyone else for making me look more into this.

More info...

Current Audi Count ---> 5

Previous Audi Count ---> 7

In spite of dealers; I still love Audi :-)

NICE!!!!!! hopefully someone can do a voltmeter/boiling water test - ModifiedA4 2004-04-29 08:42:09 (263 views)

No doubt! Thank again! - QCRAZY 2004-04-29 08:53:16 (275 views)

thanks for the update...not a good sign that the o-ring isnt the same... - ModifiedA4 2004-04-27 14:05:16 (284 views)

Cool (pun intended). Can't wait to hear the results. - DAP@PEB tuning 2004-04-27 14:00:54 (245 views)

What's the conclusion?? :) - axecheerful 2004-04-22 08:10:35 (259 views)

It keeps coolant flowing, not oil... nor does it (m)... - +pressure 2004-04-20 16:12:09 (309 views)

My 98 vr6 gti had the same pump and that thing ran.... - blslhi 2004-04-20 15:31:35 (352 views)

if anybody in socal has one of those i'd be glad to guinea pig for a bit - nyet 2004-04-20 15:50:09 (253 views)

VR6's use p/n: 357 919 369E. It runs at the same temp and it's a 4-pin. - QCRAZY 2004-04-21 06:59:56 (269 views)

either that, or they are placed "better" :) - nyet 2004-04-21 11:56:00 (250 views)

so does that mean the VR6's run significantly hotter? this isn't the first post i've seen - Andrew C::FATS 2004-04-21 11:09:59 (305 views)

VR6's do tend to run hot, especially in Corrados. - LaserK04 2004-04-29 10:40:02 (249 views)

Good point....correction.... - QCRAZY 2004-04-21 12:05:55 (338 views)

tech article - ModifiedA4 2004-04-20 09:24:37 (548 views)

It won't run unless you reach a certain temp (250 degrees maybe?) - Doc@PEB tuning 2004-04-20 09:20:31 (373 views)

i dont understand why you guys just dont buy a lower temp afterrun thermoswitch. - ModifiedA4 2004-04-20 09:25:26 (468 views)

It just isn't necessary. Plain and simple, NOT NECESSARY! - Doc@PEB tuning 2004-04-20 09:27:04 (458 views)

no, but its simple, cheap added protection. - ModifiedA4 2004-04-20 09:29:53 (406 views)

There is one reason no one has done this mod. We are too lazy to find the right thermoswitch - Zzak:FATS 2004-04-20 10:14:21 (357 views)

question, if you just short it out, won't it ALWAYS run for 10 mins after shutdown, then turn off? - nyet 2004-04-20 15:37:54 (362 views)

Yes it will run for the 10min max if you just short it out. - Bad MAF 2004-04-20 15:48:15 (253 views)

i may just do that, summer is almost here - nyet 2004-04-20 15:51:24 (254 views)

No drawbacks that I ran into running it for a couple months... - Bad MAF 2004-04-20 15:56:18 (270 views)

oh, and one more, is the afterrun thermoswitch one of the relays in vag m-block 136? - nyet 2004-04-20 16:09:49 (295 views)

ok, next question, how hot do you think it gets near a turbo (ambient air, not directly touching)... - nyet 2004-04-20 16:02:01 (288 views)

somebody give me specs for the stock one, ill try to dig something up. - nyet 2004-04-20 11:03:48 (267 views)

Existing p/n: 357 919 369F - QCRAZY 2004-04-20 11:22:38 (556 views)

Agreed. If someone posted the part number of an appropriate thermoswitch, I'd be all over it. - DAP@PEB tuning 2004-04-20 10:46:26 (256 views)

i did some etka-ing last night and found about 4 mechanically compatible thermoswitches. - ModifiedA4 2004-04-21 11:55:12 (352 views)

Depends on the order. If it's shown like you have it... - QCRAZY 2004-04-21 12:10:29 (265 views)

all the P/Ns ive sourced are 2 pin only. the one i listed is a 2pin switch spec'd... - ModifiedA4 2004-04-21 12:27:47 (281 views)

Yeah, you're right...I was thinking to fast (about the pins)...had to go work :) - QCRAZY 2004-04-21 12:54:07 (277 views)

i have the part numbers/specs at home...tonight ill post the ones ive found. - ModifiedA4 2004-04-21 13:30:55 (222 views)

Cool. I'm trying to contact Behr as well. - QCRAZY 2004-04-21 14:27:14 (233 views)

ok some part numbers. im not sure of the difference between slashes and dashes with regards to temp. - ModifiedA4 2004-04-22 15:55:35 (264 views)

Great!...more.... (EDITED) - QCRAZY 2004-04-23 07:21:35 (592 views)

are you going to throw this thing in a pot of boiling water with a voltmeter and test it? - ModifiedA4 2004-04-23 10:34:02 (221 views)

Nah, I know that's how it works. I only do "the water" when the system stops working :) - QCRAZY 2004-04-23 10:38:44 (233 views)

one other idea i had.... - ModifiedA4 2004-04-23 10:40:53 (259 views)

Yeah, that would work too. Except when my wife drove the car....I better make it automatic :-) - QCRAZY 2004-04-23 10:49:02 (233 views)

yup ;) - nyet 2004-04-23 10:46:49 (255 views)

hehe, great minds think alike :) - ModifiedA4 2004-04-23 10:53:23 (275 views)

outstanding, calling my dealer now - nyet 2004-04-23 10:30:54 (309 views)

yeah it is used in the eurovan. i'd wait until qcrazy gets the part and it works as suspected. - ModifiedA4 2004-04-23 10:32:31 (240 views)

i figure if i can get it sooner than him, i might save him some cash :) - nyet 2004-04-23 10:34:24 (224 views)

Too late.....I ordered it so I'm screwed :-) - QCRAZY 2004-04-23 10:39:28 (227 views)

hehe...i hope it works out. - ModifiedA4 2004-04-23 10:37:56 (245 views)

im not quite understanding the temp analysis... - ModifiedA4 2004-04-23 07:53:09 (313 views)

Here.... - QCRAZY 2004-04-23 08:36:55 (348 views)

ok...thanks for the explaination... - ModifiedA4 2004-04-23 10:24:52 (263 views)

No, I actually meant the heater core.... - QCRAZY 2004-04-23 10:42:45 (293 views)

"could be why so many of the pumps fail"... if they would ever cycle in the first place!!! - DAP@PEB tuning 2004-04-23 08:46:05 (226 views)

I think what he's saying with that switch is... - DAP@PEB tuning 2004-04-23 08:19:03 (265 views)

oh ok...so this switch may be plug and play...nice! - ModifiedA4 2004-04-23 08:30:41 (284 views)

Nice! Be sure to keep us updated! - DAP@PEB tuning 2004-04-23 07:26:54 (230 views)

Will do! Part won't come in until next week..... - QCRAZY 2004-04-23 07:44:04 (225 views)

:) - DAP@PEB tuning 2004-04-23 07:44:38 (222 views)

SWEET. - nyet 2004-04-21 14:53:41 (270 views)

whoa, you are getting ahead of your self. - nyet 2004-04-21 12:13:54 (254 views)

Re: whoa, you are getting ahead of your self. - QCRAZY 2004-04-21 12:50:40 (243 views)

or possibly tolerances? - nyet 2004-04-21 11:56:49 (272 views)

I'll second that - stj3570 2004-04-20 13:20:07 (270 views)

If someone found/made this sensor what temperature... - QCRAZY 2004-04-20 14:41:47 (278 views)

i'd say 80-90C maybe - nyet 2004-04-20 14:45:45 (285 views)

Interesting point...oil temp isn't in there. - gk1 2004-04-21 17:04:20 (237 views)

Check block 134 - QCRAZY 2004-04-21 06:58:06 (234 views)

BTDT nothing there on 2.7t's ;( - nyet 2004-04-21 11:54:45 (230 views)

HEAT SOAK! :) - ToastyK04s 2004-04-20 09:24:16 (305 views)

So are you saying that you dont need to cool down your turbo unless the oil temp hits 250F? Mine - axecheerful 2004-04-20 09:23:46 (411 views)

It's coolant temp....112C = 234 F - QCRAZY 2004-04-20 09:50:14 (272 views)

oil temp on the dash has little to do with the local temp of the turbos. - ModifiedA4 2004-04-20 09:26:41 (252 views)

Why? What does the oil temp on the dashboard really indicate then? - axecheerful 2004-04-20 15:03:25 (217 views)

the temperature of the oil :) - nyet 2004-04-20 15:12:27 (336 views)

*ding* - ModifiedA4 2004-04-20 20:14:35 (273 views)

That is not what I am saying at all. I'm saying the pump won't run until 250 or so. - Doc@PEB tuning 2004-04-20 09:25:58 (328 views)

That means that you dont really know when you could turn off your engine... if there's only a way to - axecheerful 2004-04-20 15:04:37 (292 views)

That is identical to my own proceedure....still lost my ko3s - ToastyK04s 2004-04-20 09:27:16 (350 views)

I dont want to lose my k03 :) So does it mean I still need to idle my engine (a.k.a buy a turbo time - axecheerful 2004-04-20 10:04:31 (277 views)

I'm not worried. - Doc@PEB tuning 2004-04-20 09:27:51 (291 views)

I guess that's just that fearless midget spirit... - ToastyK04s 2004-04-20 11:26:28 (241 views)
