Hi,

What's the final word on weather this job is do-able from the top of the car, or whether it needs to be done from underneath? Are the pictures in the job above all from underneath the car?

I'm a new member... just bought a 2007 A3 2.0 140 TDI with 80,000 on the clock. Sold my 2004 BMW 545i. I miss the power but I'm loving the MPG!

It's got the classic turbo 'whine' although it's not that loud and comes and goes a bit... I've ordered the innotec kit just to try and make sure it lasts as long as possible. I know that the innotec clean is unlikely to stop the whining, but I figure the next thing will be lost boost or overboost warnings... best avoided.

thanks

David

Just checked and the hosting website is closed and I don't have copies of the images on my PC. I'll see if I google has cached them and put them back up. If not then sorry guys since the descriptions aren't much help on their own.

Why pay 45 quid for the kit when you can get Mr Muscle Oven Cleaner from Tesco for less than 3 quid. Exactly the same chemical formula and does the same job. Just take the turbo intake off, put a piece of narrow pipe down into the turbo, squirt the cleaner into the pipe slowly but surely until you see the oven cleaner foam expanding up to the top of the intake pipe. Leave it half an hour then 're-connect the intake pipe. May as well take off the EGR and exhaust manifold while you're at it, put it all back together, run your car idle for 20 mins to heat up then take it for a spin, booting it up and down through gear changes.

It's not the cost or the product that's the problem here it's that some people like to you these images as a guide since they've never done anything like this before and now the images aren't available.

I had a look and I can't get anything decent back, Google has only 3 very small images cached, I'll put them up though.

If you have these images saved then please put them up or if you are doing this job then post your own guide.

was getting the dreaded limp mode 4/5 times on some journeys tried innotec improved things but was still doing it occassionally. so tried mr muscle and had no problems since,cleaned egr whilst mr muscle working so maybe that helped too?

Im using Mr muscle next week too. Either that or fit my new turbo. Mr muscle is good as it expands and doesnt drip like innotec. Plus its far cheaper!

Ive read that with Mr Muscle you can squirt it up the EGR entrance to the turbo rather than taking off the dreaded downpipe (seized nuts)

Do you mean squirting it in the EGR intake by removing the intake pipe from the intercooler? I guess that would work, but I would be wary of dislodging carbon build up particularly in the manifold which could then drop down into the turbo.

I took my Bora to a diesel performance specialist and asked how much it would cost to run the Innotec kit through the turbo. £45 for the kit. 4 hours labour. I did it myself, an hour and a half, £2.99 in Asda.

Granted this will more often than not fix 'overboost' but 'underboost' is a different story. Seems a quantifiable amount of carbon build up in the VNT mechanism will cause the vanes to stick open causing overboost, a coal-bunker load of carbon in the VNT mechanism will cause underboost as the vanes get stuck in the closed position, or one of the vanes gets dislodged. In the end, I solved overboost in a Golf GT TDI with Mr Muscle. My underboosting Bora had to have a new turbo fitted :(

Its true- ive sticking vanes causing a overboost.

Im getting the cat cut out while im at it.

You can spray the exhaust end of the manifold of the egr pipe. Take the pipe out and spray into the turbo the exhaust side. Its best to take off downpipe though.

Ive a garrett 1749 turbo waiting to go on which i might put on- or clean the smaller standard turbo thats on now. Im not sure how the new turbo will be with my remap and if ill be getting overboosting and my 2.5bar map sensor.:. Hmmm

Best be careful doing it your way, the oven cleaner will have corrosive effects on aluminium which I think is what the manifold gasket is made from.

With regards to your Garrett 1749 - there sure is only one way to find out!! [<:eek:)]

got to my turbo easy from underneath. its held on with a kind of clip set up with one nut comes off easy used piece of card to block up hole spent time on getting card tight in hole so no leaks occured and used old tube from innotec kit to fire it inleft it a while and worked the actuator with my thumb (which bloody hurts) and it eased up noticibly.connected back up took for a blast been ok since. if it returns think ill take off and dismantle to clean properly..one thing to remember wear safety glasses because if you get mr muscle spray in your eyes if f*****g hurts!!

I left myself with a ballooned skinless index finger after working the actuator for 10 mins, found an obvious but simple solution - use a spanner with a piece of rubber inbetween to stop the spanner slipping off the rod. Working the actuator couldn't be easier now.

Haha its true.

If you have access to VCDS you can get the actuator to cycle electonically to save the fingers

But only if you have the full VCDS release, not VCDS Lite. I've seen a few folk with one of the cheap cables from eBay using the full version of VCDS, I don't have the full version but I've got one of the cheap eBay cables. I see you can buy a license for $99 from Ross Tech, I do wonder how much functionality you will get with the cheap cable and the $99 license as opposed to the proper Ross Tech cable, which is around $399. Only one way to find out...

If you do, lots of photos would be really appreciated as I want to do it sometime and I'm scared to do it!

Hi,

I know im a bit late coming to this forum... (started 2010) but im attempting the same job and could do with some help! I have an audi a3 2004 2.0tdi, so far I have undone the jubilee clip and pulled it back, but there doesnt seem to be any clips underneath?? I did have a pic or two but it appears this forum wont let me upload them... But as mentioned before, I cant see any clips underneath the jubliee clip! Can anyone advise me on what to do next? I cant seem to get the jubilee clip fully off either... How do I remove the exhaust from the turbo after this? Any help would be great!!

Thanks
