Playing with an Audi SQ5 TDI

[sn809]

Ahh ok. Appreciate the response though, I managed to find out about the provent via its website

Have you replaced the control arm Bushes? Mine need doing but the mechanic is quoting me +4k for just the lower front.
He reckon he can't get after market bushes and Audi only do the whole arm as 1 item no bush replacement.
I think I have found some from powerflex have you heard of them?
Also where did you get your Tyers from they are very cheap. I haven't been able to find anything under $410

I have heard the control arm bushes are not sold by themselves. My car only has 53,000km and no issues with the control arms yet. Some people buy new arms and others buy aftermarket poly/rubber bushes and have them fitted. $4k seems extremely expensive for a couple of control arms.

Not sure if this link will work, but Run Auto Parts is where I buy most of my oil filters etc from. If you enter your car model and then choose suspension you will see Meyle (who are an OEM supplier of parts) have suspension arms available for the SQ5. Shop Suspension for your european car at Run Auto Parts

As for the tyres, I got them on special from Tyresales. They were down from $410 ea to $335. Really happy with these tyres too.They are currently $382 KUMHO CRUGEN HP91 255/40R21 102Y Tyres | Tyresales

If you are replacing all 4 tyres at once, have a look at 265/40 R21. They are 1cm wider, but a more common size tyre so more choices and better prices.

Thanks for the awesome feedback regarding the DPF mate, comforting know they are very different motors...

I take your point about temps while doing regen on the driveway but it only takes about 5 to 10 mins to come down to zero so think I’m pretty safe. I’d do the the app thing but don’t have an android so would just be one more thing to buy. GF is not that savvy so I’m generally left to sort this stuff out...

Totally agree with your points on diesels also, wouldn’t buy another. Never know until you try though, the SQ5 still looks a decent bit of kit...

Had the SQ5 serviced again a few weeks ago by Newcastle VW Centre and have ordered a few more goodies for it. As this is predominantly my wifes car, the mods are very tame and easily reversible if required.

- 034 Motorsport Street Density upgraded transmission mount
- Ultra Racing strut brace (considerably more rigid than the factory item). Part # UR-TW2-1752
- Akebono Euro ceramic front brake pads. Part # EUR1546

Hoping the trans mount will help reduce the sloppiness in the driveline that I still have (especially 1st and 2nd gear), the Ultra Racing strut brace hopefully to add some chassis rigidity as the chassis flexes quite a bit due to the panoramic sunroof, and the brake pads to compliment the rear ones I fitted a few months back - simply to reduce brake dust which these Akebono ceramic pads do very well.

[Lucas_R]

Akebono ceramic brake pads installed yesterday. So far so good - very happy with them. Did about 10 reasonably hard stops from about 80kph down to 10kph to bed them in at a nearby industrial park. So after bedding them in and then driving about 60km yesterday there is basically zero brake dust on the wheels - eureka!!








Also grabbed a pic of the Ultra Racing strut brace (engine cover is off at the moment so behold the ugly engine underneath). It's definitely both stronger (more rigid) and better designed than the factory brace which was 3x individual pieces of thin walled steel bolted together. The Ultra Racing brace is also a fair bit heavier than the factory brace.

Really like the SQ5 posts 👍 Which are super useful being a fellow SQ5 owner.

Can you please do a install guide for the catch can install, as is which bits connect to what and where which photos?

Also be interested to know exactly where you added the Liqui Moly decarb cleaner to the system (photo with arrow please)?

Followed your guide for cleaning out the inlet manifold flaps. Mine was not quite as bad as yours, which I was surprised as my SQ5 is on 75K now.

Do you know if it's possible to code the EGR valve to stay closed or insert blanks without issues?

Please keep posting SQ5 content, really enjoy it. Especially with details of purchases and how to install 🙂

Hi - glad to hear my SQ5 posts have been helpful to you over in the UK. I will try to answer your questions below.

Intake decarb - I can take a photo if need be, but just near your passenger side headlight there is a rubber intercooler pipe that connects to a hard plastic pipe that then goes into the intake manifold. All you need is a phillips screwdriver to loosen the hose clamp on this rubber hose, then you can slide the hose off, and insert the Liqui Moly decarb nozzle. You will need a 2nd person to start the engine and hold the revs on approx 2000rpm while you spray the product into the engine in bursts of a few seconds at a time. Just make sure you do this outside where it is well ventilated otherwise you will be breathing in the fumes.

Catch can install - on the drivers side of the engine, at the rear of the cam cover you will find an accordion pipe that goes from the cam cover to the turbo intake pipe. This accordion hose is only 10-15cm long. Remove this hose, then cut off the pipe leaving just the fittings at either end (as per the 3rd photo in this post: https://www.vwwatercooled.com/forums...ml#post1312153). Using some 19mm ID rubber hose (use fuel safe hose) route from the cam cover to the inlet of the catch can, then from the outlet of the catch can route the rubber hose back to where the other connection is just at the turbo inlet. You may also need some 19mm ID plastic/nylon fittings in various angles to get everything to line up correctly.

EGR - have a look at Darkside Developments in the UK who are diesel tuning gurus. They sell an EGR block off plate (which I used for a short time on my car) as well as other mods for the SQ5. But basically no, you cannot block off the EGR without the ECU being retuned to suit, and generally you cannot block the EGR without also deleting the DPF's

Thanks Lucas.

Intake decarb - understand where you are meaning now. Took that all apart when cleaning the inlet manifold flaps. So should be easy. I'm assuming it best to do this just before an oil change 🤔

Catch can install - sorry I'm not understanding where the flow and return pipes connect exactly. Could you please take a photo and arrow point to clarify? No hurry I'm just trying to figure out if I'm capable of fitting one myself. Also a close up photo of your custom bracket would be useful. Did you consider placing it anywhere else, and does the length of pipework affect performance at all? Lastly have you checked inside the inlet manifold flap to see if it is keeping it clean? Also have you considered taking the manifold off to clean?

EGR - yes I can across Darkside Development around the same time I found your posts here. I might consider contacting them for advice. Only downside is that it is a fair trek down to them being based in Scotland. They also do swirl flap delete - which I'm not sure about.

Do you have any further plans for the SQ5?

[SQ5Raphster]

Thanks Lucas 👍

Intake Decarb - understand where you are meaning now. Had that off before for the inlet manifold flap clean, so should be easy. However some say it's best to do it just before an oil change.

Catch can install - sorry can you please post a photo with arrows showing exactly where the flow and return hoses are connected? No hurry as I'm just try to work out if I'm capable of installing this mod first. Also a close up photo of your custom bracket might be useful. Does the length of hose affect performance etc? Also have you checked if your inlet manifold flap is staying clean? I hate to think what further sooty gunk is further down the manifold. Have you considered taking the whole manifold off for a clean?

Yes it is recommended to do an oil change after running this product through the engine. I do an oil change either on the same day or the day after using the intake decarb product.

Yes I will put some info together for you over the next few days on the catch can. When I did the intake clean (shortly after buying the car and prior to fitting the catch can) I cleaned everything I could access without actually removing the inlet manifold. I do plan on removing the manifold one day and cleaning it all out - but havent gotten to it yet. Before doing the most recent decarb which was about 2 months ago (before the cars annual service) I used a torch and inspection mirror to look at the manifold flap and other areas I had previously cleaned. They were still quite clean with just a thin layer of muck on them which came off easily with the decarb spray.

Regarding the length of rubber hose, I would have preferred to have mounted the catch can closer to the engine, but I simply couldn't find an area with enough room to fit the catch can while also being accessible (needs to be drained every 5000km or so which only takes a minute or two do to, as well as checking the filter ever now and then).

EGR - yes I came across Darkside Developments about the same time I found your posts here. Will consider contacting them for some advice. However it would be a fair trek down to them being based in Scotland. They also do a swirl flap delete - which I'm not sure about ��

Have a chat to Darkside about what you would like to do. Even if you buy the parts required from them and have it tuned elsewhere (they might even have partnerships with other tuners in the UK?). Darkside are currently playing around with an Audi A6 on their Youtube channel which has the same V6 bitdi engine as our SQ5's.

Hey mate, I’ve got a A5 with the single turbo 3.0 TDI. Just wondering how hard the EGR was to remove for you? I’ve had a look at mine and there’s a few things connected to it so not sure how easy/difficult it would be lol.

Hi sorry I didn't see this post. I never actually removed the EGR when I did my intake clean. To get to the EGR on the SQ5 requires removal of the inlet manifold and some other bits - and I didn't go that far. With only 35,000km on the car at the time, the actual EGR pipes etc looked pretty clean, it was mainly the pipe and throttle valve assembly leading into the inlet manifold that was affected and got the most attention.

I dare say the single turbo V6 TDi in your A5 is a similar setup as its the same base engine design.

[I CU2]

Hey Lucas, that's all good! Yep, sorry. I meant the intake manifold runner - the way that it's connected up in the SQ5 looks the same as what's in mine. Curious to see how blocked mine is since it has 93,000km on it at the moment - looks like it's connected to a few things so not sure how hard it would be to take out/put back in lol.
