Bought a 2006 a4 for $900

[flashc90]

I was originally buying the car to do a 2.7t stage 3 project because the owner told me the engine is no good and wouldn't start for a year.















After I paid him for the car I decided to try and start it and after cranking it 3 times the car started. It's misfiring and have a code for fuel pressure regulator..

I'd be worried about the timing over advanced. Belt slipped a tooth? When was the timing belt done last?

Also the manifold runners are a decently easy fix.

I thought this 3.2 was a chain not a belt

My bad. The op never stated and I didn't look closely at the pictures.

Cylinder 6 misfire gives it away

Nice. I've always been a fan of that color.

bring to Audi to go over the recalls, for 900 you might just want to fix it, sell it make some $$$.

[flashc90]

do you guys this the code for the fuel pressure regulator could cause the misfire?

[IronAudi]

well ya, it regulates fuel, if it breaks, it would cause Fuel pressure issues

I thought about that but then I remembered that it has over 300,000 miles on it. so I am just going to keep it as a project car for my 2.7t single turbo. wont be doing that until the end of the year

[Charles.waite]

I wouldn't be shocked if the misfires were a combination of bad fuel filter/regulator and the broken manifold adjusters.

Both those should definitely be addressed.

Or carbon buildup. It is a DI motor with over 300k miles after all.

Oh yea. Shit I wouldn't be shocked at all if the carbon buildup was horrendous.

Op also plan on doing that. He 3.2s are fairly notorious for nasty carbon buildup.

[IronAudi]

im sure you could sell the motor for about what you paid for the car. Even with issues a 3.2 for a grand is a good bargain

Intake manifold runners stuck... Definitely carbon build up. I got a code for my manifold runners and did the carbon cleaning shortly after, code never came back. And that's a 3.2 with < 60,000 miles

Can the carbon build up cause misfiring also

That's a big fat yes.

[b7_Andy]

If you do a carbon clean please post pictures... I can't imagine how nasty it looks.

I definitely will. I'll be working on the car this weekend

Ok so I finally got some to to work on the car.
I changed the high pressure pump and sensor.
The cats were clogged up so I had them removed so now I have power and the misfiring is almost gone but now it's smoking a lot from burning oil.

That last photo is a good take on the superlative style our cars have...Disclaimer: I am just positively,unashamedly pro Audi
Good luck with your project brother

[IKE20VA4]

Good luck with your project! Looks like a fun one. Especially when you're only out $900. Steal...

[flashc90]

Finally got the engine out. Now I am getting ready to drop a 2.7t in

sweet!

[mpv314]

Do a manual transmission swap while you're at it! Lol

[flashc90]

Yes but I am having a hard time finding a 6 speed at the moment.... I still have the 5 speed setup from my a4 which I had the 2.7t in... do u think it will fit?

Sorry, front mounted intercooler. I thought I read somewhere that the side-mounted ones on the 2.7T were a little under sized.

I use those because it's going to be a stage 2 for now while I get everything working correctly. I will be doing a single turbo build around the beginning of new year
