i'm good. problem solved, just started respecting the car that's all. no more trips to the dealer here i hope.
just got a reading from an obd that my crank sensor is not functioning properly. i assume it needs replacing. my car stalls at low rpms. now check engine light is on. can anyone direct me to it's location? i've googled this and a couple of different locations came up. 1-front of engine block, left side, down by crank pully. 2-back of motor on driver's side, top of transmission, behind small heat shield. requires moving coolent resovoir. unless these are in fact the same location. i haven't been able to search yet.
the problem will get worse and leave you stranded if you don't replace it

Thanks, I cant believe it will be that simple. I will document this well with pics and post on Monday. By the way, I am replacing the serpentine belt as well. The tensioner is very close to the radiator! Since I have not done the belt on this car before is it the same as my other cars where you just get a wronce on the tensioner and twist it to remove pressure on the belt and simply replace the belt?
Ok, I have to say anyone with a bit of patience and mechanical dexterity can make this repair. In fact the serpentive belt took longer to replace because of it's confined space. I replaced my CPS this weekend and it took about 2 hours. I will say though it was easieer to get to it from on top of the engine in my opinion, but that's just my opinopn. The hardest part was cutting all the tie wraps along the cable bundle. But i could easily reach the sensor and bolt from on top and it took no time to replace. Just remember this is a fine thread bolt so it seems to take forever to get the bolt out. Just remember to erase the codes before starting the car. Bottom line, simple repair.
Glad to have stumbled upon this thread after doing a forum search. I just started on replacing my crank position sensor this afternoon but decided to take a break when I realized just how difficult it was to get to that tiny little hex bolt!
I posted in a thread on AudiZine with photos as well: http://www.audizine.com/forum/showth...3-Crank-Sensor
I'm encouraged to hear that it is indeed possible to remove the sensor from above since there seems to be even less acess from below. Looking forward to giving it another go once I pick up the new part!

Sorry, I can't think of anything witty for my signature.
yea, its pretty similar, but its def a PITA.. If you have big hands, its not gunna happen.. Also make sure your car isnt warm; i burnt my hand a few times on the exhaust while doing it...
Also, BE SURE to take the spacer off the old sensor and put it on the new one!!!! The first time, i didnt do that and when i started my car, i heard this grinding noise then my car shutoff.. The top 1/4 inch of the sensor was ground down... NOT FUN to have to replace that sensor twice!!!
I also would recommend not completely removing the old sensor from the car until you are for sure that the new one fixes your issue.. Having to do double the work to get nowhere is never fun!
Once you replace it, you should notice a difference immediately! Just gotta be patient with this one
This was probably a year ago, dont even know if i bought VAG yet.. I dont remember the code i was getting but i knew that my car would start in the morning, but once i got off the highway and sit at a stop sign, it would die and not start again until the engine cooled down.. I would have to keep pulsating the throttle to keep it on.. So car was basically useless unless i planned on staying at one spot for a few hours... There may have been other things, but i remember this was the biggest problems i had with it.. Hope this helps!
Engine speed sensor and CPS (crank position sensor) are the same thing. I was confused also at first when mine failed. The CPS or ( speed sensor ) read the speed of the flywheel revaluation, which determines the speed of the crankshaft, which tells the ECU some B.S. for some other B.S. to do...... mainly with everything that keeps your motor in working order. If this fails, you go into LIMP mode.... no boost, no power ect..... Blah Blah..... always fix anything on these cars. thats what ive learned. do not ignore
I hate to revive an old thread but instead of making a new one I will comment here. My car (05 B6 1.8T quattro) died yesterday while I was driving on a side street and would start back up for a second and then stall again. I'm not sure if its the CPS or if it's a fuel pump issue.
