S.O.S

When pulling from sub 3k rpm the car revs up to 3200rpm then the Rpms drop to 2900-3000 then the car pulls away from there. Furthermore the turbo makes a higher pitched whine than it used to. I have the updated pcv and diverter valve on the car so I dont think it's those. Especially considering how new both those parts are. I do have a forge dv bov adapter could that be leaking? I don't see how it could but I'm worried its a bering as it's happening just as the boost kicks in. Oh and it only happens in 3rd-5th gear.

Clutch

[jrtrainor]

I really hope not

[jrtrainor]

When just starting out the drive this morning it didn't do it till about 15 min in. It does it under light acceleration it's like the engine stops responding to the pedal for a brief moment then runs perfect. Will post video if I can.

i had something similar. after the car was warm, in 4th and 5th gear WOT my RPMs would surge from like 2500 to 4000 and it would feel like it went into nuetral for a second and then the car would 'catch' again, rpms would fall back to normal. I thought it was a slipping clutch. this happened for about a week but it hasnt happened in about 2 months. try a search on here for 'rpms surging'.

Same thing happened to me when I installed the 034 HFC and went Stage II. Changing the plugs to the NGKs (check my sig), gapped at .028, helped.

[jrtrainor]

Plugs are new 500 miles Rpms aren't surging they just drop by 1-300 then it goes again. No feel of neutral just like the gas pedal stopped working for a second

[fordyoz]

OH. my mistake.
so it limps for a second? fuel cuts?

[vwnobby]

Sorry, misread that. Thought you were having a surging issue. Fuel filter maybe?

[fordyoz]

haha ditto

[jrtrainor]

Fuel cuts sound much cheaper to fix than a clutch which is good news. I also have a new cam follower in there so I know it's not that. I've got it in the shop today for an s4 brake upgrade and kw v1's so I'll have them take a look at it.

One way I tested my clutch for slippage (which it was) was on the highway, just cruising, tap you clutch pedal so the clutch disengages for a split second then let off with your foot still on the gas. It the RPM's climb then fall like you're describing then it's a bad clutch.

[jrtrainor]

It's definitely not the clutch I know that for sure. My buddy who's a rep at the stealership told me to take the negative terminal leed and connect it to the positive terminal then leave it disconnected for 30 seconds. Reconnect drive for 20-30 miles and see if the problem persists. He told me its most likely the capacitor from the turbo.

The capacitor from the turbo?

Haha It's a joke..

[jrtrainor]

I wish it was that kind of capacitor. Haha an but seriously I didn't know tho part existed. What's it do store a static charge built up by the turbo?

[DRAKLORE]

I honesty have never heard of anything referred to as a turbo capacitor? Maybe it's got another name, or he's fucking with you lol

[jrtrainor]

I think the most logical answer is i don't know the name of the part. Whatever it is this process resets the majority of the cars electrical bits and should fix said underlying problem. I don't think he's messing with me or if he is this would be the first prank he's pulled on me. I'll ask some more questions and get my parts straight

[jrtrainor]

So the answer is I totally misheard him and it is simply a capacitor discharge for the modules. Forcing them to fully reset and reboot. Nothing to do with turbo's. I'm just deaf and still a noob when it comes to turbo cars.

[wildbill]

first...youre friend is mis informed....start with your maf...a flutter under partial at low rpm's. sounds sensoer related but start there. remember the ecu takes almost a dozen values from different sensors to determine afr.

[groundround]

n276 on the hpfp is also another option, mine went and had similar symptoms till it just stopped working you don't go anywhere.

Do you have any pending codes?

Flux Capacitors are only used at 88mph+ FYI

That could be a COSTLY Mis-diagnosis....

[jrtrainor]

Since I have been trying to figure it out the problem has spread to a surge in rpms. Meaning its the clutch. But we for the longest time could not figure out why it was dropping in rpms. Idk whatever happened before is either still happening and can't be noticed because of the clutch or was a goofy way of the clutch acting up and now I have a more tell tale sign of bad clutch. My friend is not mis informed however that is the exact fix procedure for the car that Audi uses to fix electrical problems that don't present with a code. Not the right fix for me but the correct first step in trying to figure out what it was.
