looking at 1-7 I say 6 is what I need to do. I need to borrow the vcds again from my contact to do the TBA
but before that I want to get in there and clean it this weekend.
Question: should I be cleaning any other components in that area while I have it open. would there be anything to be done to the PVC while in the area in terms of cleaning or examining ?

the last tune up I did was at 140K/KM when thremo, belt, pump, plugs and filter were done. Now I am at 175K/KM.

As I said, all I seem to notice now is resistance on way up at 1000rpm and then and then a small fight to brake at 1000rpm (where it seems to push back on me trying to brake)

So until I clean the TB and scan I cannot give you final results.

might have found the last part of this poor driving condition.

about 3 weeks ago I changed oil by just draining pan for 3 hours.
not knowing how much was left behind, I filled with 6L of Mobil1 10w-30
I was overfilled.

reading on symptoms of overfill, I began to realize that the issues could be some of those I was experiencing.
I felt I wasn't over by too much but I now think I was at about 1.5 L over....too much.

engine was running hot and acceleration was soft and weak. also had that needle jumping around 1000rpm.

so I drained again today via pan. gotta say the oil that came out didn't look only 3 weeks old. it was almost black but still had go viscosity imo.

went with 5w-40 instead.

result is the needle jumping around 1000rpm is gone and the sluggishness too. the rattle while climbing is also gone.

lesson learned and hope that nothing long term has occurred because of this.
never thought to much about it as I never saw oil burning from exhaust

You should always check the oil after a change once you get the car back level on the ground.


I usually wait to add the last half quart or so till its off the jack stands.

Bahahahaha...,sums up my reaction perfectly! Hate to say it, but some people just need protecting from themselves.

So true !
Hey I'm no techie.
Hopefully some learn from my mistakes

I have seen the results of using a non-approved weight oil on the v-8 engine. It isn't pretty. The cam shafts is what suffers most. That engine was designed for 5-40 synth oil. Using too thick an oil results in too little oil getting to places where it should.

Audi has a maximum mileage interval for oil changes. Changing the oil more frequently will result in cleaner engine internals.

Never overfill. It says so right on the dip stick.

allenst

somewhat correct.
I agree with the "40" part but in Canada with extreme temperature swings and an older hotter engine, the 0/5/10 are debatable (on the oil thread)
the 10-30 I used was rec by an indy. I didnt like how it felt and I had overfilled so drained it after 3 weeks.
put 5-40 syn in. feels good now.
splat!

5-40w fully synth should be fine. Euro specs 0-40w so there you go. The key is not to mix viscosities.
