2015 Audi SQ5 3.0 TDI Biturbo

[Lucas_R]

I just read your latest update last night and was going to ask you what parts you needed replacing.


If its the upper control arms then these should be the replacements (theres 2x on each side):

034 - Density Line Upper Control Arms, Audi B8/B8.5 A4/S4 & A5/S5/RS5– VAGPARTS Australia

Engine mounts id get OEM replacements for $1,295 unless you can find cheaper.

Not sure what the front buffer torque mount is referring to?? This might be the transmission mount? Its just a tiny piece of rubber so not worth shopping around as $95 is cheap enough.

Rear centre diff bush. Suprised this is worn out. I would fit an 034 Motorsports insert to see if this buys you some more time. The034Motorsports insert reduces the movement in this bush (i have one on my car) 034 - Billet Aluminium Rear Differential Mount Upgrade, Audi B8 & C7 Series– VAGPARTS Australia

If you do the 034 diff mount, then you might want to consider this kit which offers transmission mount bush, diff carrier bush and diff mount. I have this in my car and it just tightens everything up nicely without any NVH or vibrations.

Thanks mate

They're saying it's just the bushings on the upper control arms, would you recommend still getting the whole control arms, or just replacing the bushings?

I've found a few options for bushings:

Run auto parts tell me these are the ones: Upper Lower

A vehicle model search on Powerflex yields these (though polyurethane..): Upper Lower

Wasn't sure about the stiffness of polyurethane but seems OK on their "road" series product with a tapered sleeve to alleviate it a bit.


I have that insert package from 034 in my garage already - bought it a while ago after seeing your posts - I haven't had them fitted yet but will do so next time it's in the shop.


In terms of engine mounts, I have found these:
Left Right
Pricing seems acceptable

Hey @Daniel_M,
Really enjoyed reading your posts.
My SQ5 is experiencing the exact same lumpy idle issues.
You mentioned a shop in the North did the work for you. Would you be happy to recommend them? If so, do you mind pinging me the shop name please?
Cheers.

PM'd mate, best of luck with it!

I know Revhigh in Hallam have done the carbon intake cleaning and performance tuning on various SQ5's and other Audi vehicles with the 3.0L V6 biturbo engine. Might be worth speaking to them.

Hi Warenza,

I currently have the same car with the same error codes intermittently appearing. Was wondering if you could tell me where you purchased the Boost Pressure Solenoid Valve from?

Cheers

If you Google/ebay search the part number you can find them online for about $160 AUD. Only issue is that they come from Europe so you will have to wait 3-4 weeks for delivery.

Hi Lucas,

Thanks for the quick reply, yeah I saw that too, was hoping that there was somewhere in Australia that sold them.

Doubt it - unless you want to order through Audi themselves (via your local dealership) or possible VAGParts in Sydney....but very likely that they will have to get it in from Europe anyway. May as well get rid of the middle-man and just order it directly.

I guess I have to bite the bullet, order and wait 4-6 weeks for delivery. Hopefully it'll resolve the issue once its installed.

Hopefully it does. Worst case it doesnt but its only $160 and at least you have ruled that out as the issue.

Hey @Daniel_M, Ive come across your thread as I was trying to search for peoples personal experience with a Stage 1 tune with the EGR/Adblue/DPF delete. It looks like its been a good few years since you've done it - how is it all going now? Any regrets regarding deleting the dpf etc?

The reason behind me asking is, Im currently going through what you and Lucas R went through with a blocked DPF (i also do many short trips (most under 10mins)), and I want to prevent it from happening again. As it is the family car, i didnt really want to delete the dpf due to extra odour, soot and smokiness.. so im still on the fence about going down that route.

Hello mate. Been a long time since I have been on here... some more bits have gone on the car, will have to update the forum at some point..

To your question: absolutely zero regret/negatives to the items you mention. If I split it into two:

(1) the tune - very happy... car is sharper, and pulls hard. I already enjoyed driving it, now just more so. Fuel consumption is about the same. Really no downside to this as you can still drive it 'softly' and it can still act as a great family hauler. It just has more of an edge to it, if you feel like pushing it. I like the guys at Underground Performance, if you are in Melbourne, they were good to deal with.

(2) emissions stuff removal - no noticable downside. I mentioned the smell if you are parked with bum to a wall and leave the car sitting there idling for a bit - yes, you will smell it. How often does this happen.. pretty rarely. Not terrible, but it's there, in that rare circumstance. All other scenarios you would never know the difference. Zero smoke from exhaust. Great not having the trips to the mechanic with stuff blocking up! If removing DPF, just remind them to recode so the adblue stops getting added to exhaust - lesson learned there. Removing the DPF seemed to ruin my exhaust speakers. Not an issue as the car is loud enough minus the DPF. Seems like Lucas might have a solve for this if it is important to you, but I havent't found the need.

My car is now up to ~155k on the odometer, still great.

Might look at the intercooler idea after catching up on Lucas' thread!
