Poor running 3B ---FIXED!---

Sat Jan 8 11:40:53 PST 2011

Yep! Went out to Anderson Motors Sports (owners drives a 91 Avant)   They 
had a used MAF from a S6, same part number.  Plugged it in and all is  good.  
Also the used MAP got rid of the reoccurring code I was getting for  O2 
sensor and ISV.  No more codes, never had a MAF code.

New problem is, was driving last night and lost Power Steering and Brakes,  
limped home, reservoir empty and no green gold dripping from anywhere under 
the  hood.  Dumped in my spare can and got steering and brakes working 
after a  short drive pumping the brakes.  The liter I added did not fill the  
reservoir (used flashlight and verify that. Reservoir was MT last night when I 
 parked the car.  This morning when I opened the hood, I was surprised to  
see the reservoir near full, went down to about a third after starting the 
car  and turning the wheel and pumping the brakes.

Went and bought some more green gold today, topped it off and drove 30  
miles, no leaks and all works.  Got no idea what is going on there.   Did have 
a puddle about a year ago where it puked out some green gold (once  only), 
and than there was also no sign of a leak under the hood, pump rack,  hoses 
etc.  Presumed it might be out of sight in the brake booster.   WTF!!

Did notice that gasket under the PS reservoir cap is bad and would probably 
 leak some air in, but all dry around the cap. Never got a red brake light 
during  this.  My autocheck light does not work on the dash and I do have an 
 occasional beep, but that has been there for awhile.

Sure would be nice to have a newer car!
Thanks,Pete

Cap, rotor, wires, plugs and wires have about  40k on  them.  Look good and 
dry.  Started car yesterday no difference, am  going to pull codes today.
Thanks, Pete

Its possible, but I wouldn't condemn it yet. You mentioned ice storm  and 
rainy... how old are your wires? how about the cap and rotor? Id pull  that 
and dry them off first and see what that does. If they are new and  decent 
then you might be looking at a maf. When my MAF went it was pretty  smokey at 
idle and couldnt pull any boost at all. not even 1 psi

Think you jinxed me!  Was driving home in the worst ice storm I  have seen 
in Minneapolis.  Car suddenly starting running like  crap.  Bucks, wont 
usually idle unless I hold the peddle down a  bit, must accelerate very slowly 
to make any  speed.  Bummer!

Car ran perfect before, however had two intermentant codes.  O2  sensor and 
ISV.  Have had an O2 sensor on order, first one came in  wrong part.  Did 
not pay much attention to the ISV because the car ran  perfect (238k miles).

Unplugged the MAF sensor, no difference in car running, pressured  turbo 
and vacuum system to 15 psi, no leeks, pulled and cleaned MAF, no  difference.

Started to rain again (have to work out side) so I quit for the  day.  Will 
clear and pull codes tomorrow.

Think I am on the right path with the MAF?

Thanks

Well  thanks to VAG com... this morning I pulled the codes, there was only  
1.  
MAF.   I was actually kind of happy to see  it.  So I went online (audifans 
marketplace to the rescue!) found  one a few hours away from me for a good 
price 
so I went to go get it.  Came back about half an hour ago, installed it and 
all 
my problems  went away! Idles great, no smoke, runs amazing, and pulls like 

nobody's business! I am so unbelievably relieved.  It was cold so  I gave 
it a 
little temperature, and got to maybe 12psi boost and it  was effortless and 
smooth as silk. Ill definitely sleep well tonight!  Or maybe not...Ill want 
to 
get up early and go drive it!
Thanks for  everyones help, I appreciate it. Looks like Im good to go  now.

Here's a picture of the patient. Its a 1985 UrQ with 3B that  has all the 
RS2 
goodies. Therefore Its painted RS2 Pearl blue. It has  the tall wing, 
blacked out 
rear lights, euro lights up front and sport  hood. 

This was an 'in progress' picture, you will notice its  missing the drivers 
side 
windshield wiper, has the 5000q wheels on it  (winter tires) with no center 
caps, 
and the front grills for the sport  hood arent clipped in, they are just 
laying 
there. Thats all been  fixed now (except the 5000 wheels, the sport q 
wheels wont  
go on till summer).  _http://maxboostracing.com/RS2UrQ.jpg_

Since you  have VAG--COM, have you checked Group 0 , the one that has many  
operating conditions like load, intake air temp, RPM, TPS, etc? It is  
designed 
to be read at idle and lowish RPM. The Bentley will tell you  what the in 
spec 
ranges are for the various readings.

Your MAF  may only be slightly out of spec, which means it may only need  
cleaning.

Cheers,
Brady
