A little help from the car guys?

[OnTheWarpath15]

I'm stone fucking stupid when it comes to cars, and figure there are enough car guys out there that might be able to help me out.

I drive a 2009 Volkswagen CC with manual 6 speed transmission. 2.0L DOHC Turbocharged engine. Car has 40,000 miles and has been maintained to the letter.

It doesn't happen every time, but I'm noticing a slight engine hesitation around 2900-3200 RPM, but only when I'm in 4th gear. It feels very similar to the slight "turbolag" you get at 3800 RPM with this engine.

No warning, check engine lights etc. are on.

Any thoughts?

[notorious]

Are you reving up or dropping RPM thorugh 2900-3200 when it happens? A lot of times the A/C unit can pull enough juice to simulate Turbolag.

The car is new enough it can't be a hole in the muffler. Check and clean the air filter, too.

Antifreeze?

I'm actually cruising at a steady speed. Typically between 45-50 MPH.

Air filter was just replaced two weeks ago during 40,000 mile scheduled service.

Zip it, fucker.

LMAO

i have a customer who drives this car.

we change her fuel filter when she starts to feel the lag.

i would try that first if you havent changed it in a while. (10,000 miles)

I edited my post above. Check your air filter and even a slightly low tire can effect the car like you are describing.

Blocked fuel filter might be a possibility, too.

Beat me to it. :D

[OnTheWarpath15]

Also, I've yet to have this happen at higher or lower RPM's, or in a different gear.

Weird.

[notorious]

I had a fuel pump act up in one of my work vans just like you are describing, too. It would get to 50-60mph and just loose all of it's balls. Fuel supply is usually a large percentage of power problems.

I'll have to check the service records and see when it was changed last. Everything to this point has been done by the dealership as part of a free maintenance plan.

[SuperChief]

Check the blinker fluid.

[notorious]

My final "guess" is a fuel filtration issue in the fuel tank or inline at the filter.


Don't overlook the air filter. Air is just as important as fuel when making power, especially in the low RPM range on smaller engines.

For the record: I love that car.

If not for the fact that I could get a Sonata with absolutely everything for about 3 grand less than a base CC, I'd have grabbed one - it's a stunning little car and the interior is as nice as I've ever seen if you get the 2 tone black/cream leather.

I used to sell for the VW dealership I bought from, so I got it below invoice. I love this fucking car. First issue I've had with it.

I'm actually surprised I haven't been pulled over for the window tint.

What % tint is that?

Yeah, but my little Hyundai would still smoke ya and do it on 87 octane without needing synthetic oil ;)

The styling on the car is just much more fluid than the Sonata, IMO. It has a more refined European look to it, as opposed to the more linear, aggressive, Japanese look that the Sonata has.

For looks, until you start shopping Mercedes, there's just not anything that compares with that car in mid-size sedan market, especially when interior styling is considered. It's a little polarizing, but I love the interior of that car.

[OnTheWarpath15]

20% all the way around, IIRC.

Same here. I just detailed it yesterday, and fell in love with it all over again.

I know the rear bucket seats turn a lot of folks off, but I love it. Then again, the Mrs. and I don't have little ones to worry about.

I've driven nothing but VW's since 2003, and have been extremely happy with each of them.

[Radar Chief]

Yup, change filters first then it doesn’t hurt to change spark plugs. I like changing them anyway to keep track of how the engine is burning fuel. If an issue within the engine starts to develop this is typically where it’ll show up first.

[modocsot]

I drive an Audi A6 bi-turbo. Your symptoms may be related to a slight vacuum leak. Have it scanned with a VAG-COM while driving, as you try to replicate the symptoms... It'll likely throw a code.

i would just have it changed if thats the case...



and on my PM i thought it was a diesel for some reason...the filter might not be where i thought it was. lol

It's not. I just went out and looked, and nada.

If it's anything like my older VW's, it's right in front of the rear passenger tire.

Can't find the goddamn owners manual, either.

Some of the new VWs have a false bottom in the glove box that holds the owners manual.

yep, i just said that in my 2nd PM.


:banghead: sorry dude, dont know why i read that as a diesel

Damn Big Pimpin', watch out. Sweet ride. How much that set you back?

Rep, though it was a false top.

It's always been in the actual glove box until the last time I took it in for service. Guess the tech put it back where it belongs.

[hometeam]

If the sympton doesnt come from fuel you might be having a problem with your cam follower, and this could be your first tip off that something is wrong. This motor is known for cam follower failure, it is fairly common. Most cars with this motor experience it at LEAST once before 50k miles, it has some kind of special coating that wears off and can cause problems just like you have described. IF you wait until it fully breaks, your talking major bucks, you could lose a cam, and lots of other issues. If its not fuel, replaceyour 15 dollar cam follower~

[OnTheWarpath15]

IIRC, the sticker was 28,500 and I got it for just over 25,000.

[CrazyPhuD]

Or it could just be the car too.

I wanted to see a dyno to see what the power curve looked like. While this is only one dyno and it appears to be one with intake and exhaust. One thing that IS interesting is that there is a significant torque drop right between 2500-3000 RPMs which is right in the range you claim. (Dyno graph is at 1:46 second).

Could just be that's how the engine breathes and you only notice it in 4th gear because that's where the mechanical advantage is low and your throttle position might now be opened as far as higher gears.

So while it could be a blocked filter, it might also be 'normal'. The question is, is it new or has it always been there.

Wow, really? The sticker was only 28K? I don't know shit about VW's but just looking at the thing I woulda guessed the 45K range.....

[King_Chief_Fan]

It has to be the muffler bearing thing again

[HemiEd]

Have you checked the muffler bearings?

This is a new issue. Never noticed it until about two weeks ago.

I checked the Fetzer valves as well, fellas.

That's what happens when you rip off the S-Class.

Props to VW, they stole the lines from a damn nice car.

[Molitoth]

First thing I would do is change the spark plugs. Do some research online about the plugs that can run in this car. My car ran stock Platinums which are expensive as shit, but many tuners have found a certain cheap copper plug actually works the best for the car. What a difference those made.

Many turbo cars have ignition coil issues which can cause the power cut at higher RPM's as well. Keep this in mind after you try the easier possible solutions.

[BigRichard]

How about the Flux Capacitor?

VW is making really affordable automobiles atm. I just picked up a 2011 Jetta SE for the wife at 0.9% financing.
I liked the CC, but she wanted a Jetta cause it was "cuter".

[Tytanium]

Check bypass valve? Boost leak?
