Throttle body problems

[dturn37]

So I've been having a slight rpm spike when coming to a stop in my 2007 Audi RS4. I suspected that my throttle body was dirty and needed to be cleaned. I pulled it off and noticed it was dirty. Cleaned it and replaced my air filter while everything was off with a BMC filter. I ran the throttle body adaptation via vag com and everything ran great with no fault codes. The next day I accelerated hard and lost all power. The cel and epc light came on and had to restart the car a few times to be able to get power back. I got this code 005445 throttle valve controller malfunction. I tried to run the adaptation again and got an error that wouldn't let me do the alignment. I pulled everything off again and reset my ecu. After doing this it allowed me to do the adaptation and everything ran great until I accelerated hard again. Is this a sign that my throttle body is faulty? Should I try getting some electric cleaner and clean the plug on my throttle body? Maybe I got some cleaner in there. Could this be a cause of the new air filter? I checked my maf sensor and it seems to be in good working order. With my luck I damaged the throttle body while cleaning it. Any help will be much appreciated. I found a used throttle body for cheap so worse comes to worse I can get that and try it. Has anyone ran into this problem? I keep trying to retrace my steps and it's driving me crazy.[headbang]

Since you've cleaned it, try some cleaner on electric connector. Could be sorry connection. If not, TB might be going out. Mine is throwing a sensor position error. I occasionally go into limp mode. It's not happening enough to swap my TB yet, but that is the plan. You may need a new TB also.

[dturn37]

Thanks for the help! Yeah I have a feeling its my TB going out but I'm cleaning the connector now as a last ditch effort.

[your daddy]

i have done a few throttle bodies for customers in the last couple years. not uncommon.

My throttle body is on the way out, too. I've seen in a few places that the RS4 uses the same throttle body as the LS7, which you can get for about $150-300 for the GM version on eBay, but the Audi version is $1100 or so. Can anyone confirm that these two parts are interchangeable? Has anyone successfully used the GM throttle body in an RS4?

So are you actually running this throttle body?

no ,but i installed a few off them already on rs4s and no problem

That's interesting. So Audi sourced this from AC Delco?

No, I forget the name, but there's an outsourced company who makes them for GM as well as Audi and a few others.


edit - it's "Pierburg." Here's the underside of mine that I got a photo of a few weeks ago -

When you say "out", what do you mean? Mine did and finally got it changed. The flap was getting stuck. Let me add a quick video here to show what I mean. I wish I had known about the GM throttle body. I would have save $1k

I mean that the car is constantly going into limp mode. Throwing codes p0223 and p0121 (I think, don't have the sheet in front of me).

Here is mine from a week ago. It took two weeks for the throttle body to arrive of course. Car has had no issues since then, but it has only been a week.

What were your symptoms?

[wednesday]

What were your symptoms?

From cold start: No issues. I was able to drive on highway with no issues for hours (I mean 18 hour trip). But, if I got stuck in stop and go traffic, I would suddenly be out of power and EPC/CEL would come on. To fix, I would turn the car off and on, then it would be fine.

This would also happen if I started the car warm from a stop. So if I went inside wal-mart for 15 minutes and then started the car right back, EPC/CEL would come on. I would then turn it off in motion, and turn it back on.

This got so dangerous that I was merging into a lane one day and car lost all power. Car coming up from the side would have just blasted me from passenger side since I had no acceleration power, but quick turn off/on and acceleration saved me. Keep in mind, time to accelerate/notice power loss/turn off/turn on takes a few seconds which can be a matter of life&death in some rare occasions. If I had not been accustomed to it, I would not have been able to come out of that situation. So, yes, if someone asks, is this a good family car, my answer wouldn't be favorable to many.

Wow that's insane. For $150 I think I might keep one in my trunk hahaha!

Found a site that has the throttle bodies for around $200 (and listed for the RS4!). This is probably the route I'm going to go. I'm still worried that the GM part is somehow different than the Audi part, and finding the GM part is harder than I thought it might be since they switched throttle bodies for 09MY so the blade opens in the opposite direction (silver blade is what you want, not bronze like in the link above apparently).

Anyone used these guys before?

Looks like you're correct on that. The correct OEM PN is 12570790. Never heard of automotix but that price is way lower than everywhere else I can quickly find so it seems suspicious.

Are these are used TB's from various auto salvage yards around the country?

[mattshaver]

Yeah, seems to be. I've been looking around, and there are a ton of bad reviews for Automotix. Probably going to go with the GM throttle body after seeing a bunch of bad reviews.

Please let us know how it turns out.

Rockauto has the Corvette TB for only $136. Its the Ac Delco. Here's the link http://www.rockauto.com/catalog/moreinfo.php?pk=1321927&cc=1442776&jnid=559&jpid=3

That's the one where the plate turns in the opposite direction as ours.

Cheapest you can get is probably going to be a remanufactured one. Search rockauto for 67-3003, it's $220 prior to shipping.

[evolution2147]

Is it possible for the TB to be going bad but not be throwing codes? My throttle seems to keep dipping at lower speeds as if I'm taking my foot of the gas. No codes or misfires and traction control is completely disabled.

I think I may try one of these GM ones just for the hell of it.

That's what I ended up going with. The RS4 goes under the knife next week on Thursday. Will report back.

[dolby2thx]

OP, so where have you decided to purchase the TB from? Who is doing the install?[wrench]

[dturn37]

Before knowing about the cheap GM option I ordered a used one from ebay for $100. I managed to get some electric cleaner and clean the plug on my old TB . It seems to have fixed the problem so I'm guessing I got some Throttle body cleaner in the plug. I'll just hold on to the one I got on ebay just in case it fails again. The throttle body removal and install is really easy actually. Can be done in about 15 minutes when you know what youre doing. If you need any help just message me and I can help you out. I'll try and take pics next time so I can make a how to...

I also cleaned the throttle body and that did buy me three months. When the issue came back, I went and got it replaced.
This is an opportunity for JHM/APR/...etc to make their own or perhaps adapt the GM version and sell it for 1/4th the price. Win/win for both (consumer/vendor).

Since many RS4s are now out of warranty, this issue is showing it's ugly head. I bet it was getting resolved by the dealer before so it wasn't documented.

The fact that this effects so severly and then it has to be garaged for weeks since it's not easy to source a replacement is pretty ridiculous in this day and age. Or am I driving such an old car that parts aren't available readily? Who knows.. my rant of the day folks. :)

I just remembered today that I had identical symptoms on my b6 a4 3.0L. It happened once while I was on an onramp, luckily not while I was about to merge. The car was actually sold back to Audi of America by the PO for "loss of power" issues and the throttle body was replaced by AoA but still didnt fix the issue. I ended up fixing it by replacing the coilpacks with the revised ones and got a huge discount on that car.

Good point. Every other V8 sees gains from increased throttle body size, why not ours?

[mattshaver]

So I can confirm that the cardone remanufactured throttle body for ~$220 is indeed an option for our cars. Just had one installed by 034 today. Rockauto.com search 67-3003.

Supposedly, when the engine was developed the engineers were so proud of the design they said they would be surprised if the aftermarket could tweak any more power from the engine.

Searched this part # on rockauto and seems you have to send them your original, they rebuild, and send back - is that accurate?

The A1Cardone throttle body is plug and play? Did 034 have to modify the connector plug?

It looks like theyve run out of stock on those. Some ****** probably bought them all out to resell to unknowing RS4 owners at high markup. :) I plan on buying new PN 12570790 on rockauto and sending mine in for remanufacturing later.

Has it been confirmed whether that GM part # functions like OEM, that is it opens in the same direction? Thought there was some debate on that...

afaik, there isn't a core charge or anything. maybe only when they run low on stock? i have my broken TB sitting in the cardone box right now. any takers? :-)

if you do go the GM route, you should be sure to get the silver blade. the bronze blade TB opens in the opposite direction. that's the feedback i found on a few vette forums at least.

[robr4793]

Does anyone have a direct link to the gym throttle body.i clicked on it and the bronze one appeared. I was under the assumption that we can't use that one. Only the silver ones.

[evolution2147]

The GM one definitely does not open in the same direction, the electrical connector is slightly in a different spot and the the GM version is a little more beefy and it hits the high pressure fuel rails. I was going to try it out anyways since i already bought it and figured at worst case i can just take it back off but after trying to bolt it up i didn't feel like modifying my fuel lines. Especially since I'm pretty sure the throttle body isn't my problem. Also it does not say Pierburg anywhere on the GM T-body.

This is the one i bought, got it for $127 shipped a few weeks ago. its the same part number that was listed on page 1: http://www.amazon.com/ACDelco-217-3153-Original-Equipment-Injection/dp/B001NZZ9K2/ref=sr_1_1?ie=UTF8&qid=1442684055&sr=8-1&keywords=ACDelco+217-3153+GM+Original+Equipment+Fuel+Injection+Throttle +Body+with+Throttle+Actuator

Wonder if opening in the opposite direction will be an issue.

I wouldn't mess with the gold one, according to the vette forums it throws a code at WOT. (Not to mention you will need to do some modifications in order for it not to hit the fuel lines). According to the vette forum the gold one is a cheaper version that GM starting using in 2009. That could be why it doesn't say Pierburg on it. The gold one is the part number that quattrors4 listed so for some reason i just believed him lol. I can just return it to amazon so no biggie but the sad part is it looks like the correct 2008 GM version is almost $400.

Im still not 100% sure of the compatibility but this may be the right one:

[robr4793]

the Gold one looks much beefier than our stock one lol. To bad the vett people says it has problems. I think it would be cool to run the gold one. It actually looks like you can enlarge that one for a little extra gain. Well silver one from Rock auto it is
