    As my car is coming up to it's 10,000 mile mark, and also being two years old, I am going to do what I have done to all my previous cars and try out a DTUK tuning box.

    So, after consulting with them about the installation I have placed a order today, but I just had to check that all the connections can all be accessed from the top. Looking at pictures from a Q5 it seems like the boost sensor is just about accessible ok, which is the one that is difficult on a transverse engine such as the A3.

    Looking forward to testing it out on our journey to Suffolk in a couple of weeks time but, if anyone's interested, I can post up a fitment guide.

    Good choice, I'm sure you know you'll enjoy it if you've had on previous cars. :)

    They all come with a fitment guide though do they not? Mine was a few A4 pages of colour photos and made it a breeze to install (and the sensors being very accessible helped too).

    Yes they do and they have already sent me a copy. I have fitted one before to my A3 1.4 and that was all accessible from under the bonnet but I'd seen that on the transverse 2.0l engine you had to take off the under shield to gain access the boost sensor from under the car, so it is a relief I shouldn't have to do that.
    Oh and I've ordered the app to go with it as well..

    Ok so I think I have found one of the boost sensors to the right of the engine, as you look at it. Does anyone agree?

    @cuke2u what kind of performance does this give out?

    Well it is fitted and I must say it was a doddle compared to the one I fitted to my A3. On that one I had to remove the air cleaner box and some of its plumbing. Even then one of the connectors was difficult to release.

    The only fly in the ointment is that the bluetooth will not pair, keeps telling me that the code is incorrect, however it doesn't tell me where to put in the correct code. Guess I'll have to email their support.

    I have taken some pictures, especially those of a naked engine :scared2: for anyone interested, but the supplied instructions made it easy.
    Haven't had chance to road test it yet though...

    Will do when I get to drive it. I might have resolved the bluetooth pairing issue as I had 'allow devices to discover my phone' turned off. I am sure turning it on will make a difference so I'll try again tomorrow as its almost wine o'clock time now.
    I have for now mounted the box here, but if anyone could suggest a different place then feel free. However it needs to be on the left, or behind, because of the length of the wiring harness. It doesn't touch the bonnet:

    Looks good but it looks above turbo or manifold so look out for heat as it looks like other equipment below has heat shields

    Thanks, yes aware of that which is why I have placed it as high as I can. Below is all this malarky, but nothing is wrapped in any heat protection near the unit as can be seen with the rubber piping:

    It's very much work in progress and temporary but higher than the plastic engine cover, so I was assuming if that hadn't melted the risk of heat influence is low...

    Paired the app ok this morning and all is working good. Took the car out for a brief run and what can I say. Smooth, sublime, refined and effortless, it is just good, no not good bloody brilliant....

    Does the improved engine performance have any impact on gearbox (s-tronic) performance? Would be interested to know if the lag is reduced at all.

    I have never noticed much lag really but I haven't really driven the car much post fitment yet. We have a long journey to make in a few weeks time so I be able to test it further then...

    Any update on this Cuke as I'm sitting on the fence about one of these still but it's on my list of mods for sure

    Can't report any more than from my brief test drive on the 5th and I'm not going to be driving the car until the weekend. Apologies but it is our holiday season and I am only driving the fiesta at the moment. However the round trip I will be on should provide information...

    Been running a TDI box (similar to DTUK) on my s5 for about 5 months now. Can't say anything other than positive things.

    Good job your with the majority in the UK, because, out here a many of our fences are still barbed wire. That would fix your procrastination. ;-)
    Its not like installing a bigger hairdryer or cams or whatever. The box is after the ECU, so it can only produce up to what the engine is capable of, providing you treat it with respect. Manufacturers build engines with low stress allowing for year on power increases without major redesign. Using economies of scale, manufacturers can utilise the same basic engine for multiple purposes.

    There is an adage that says that one does not appreciate an item until its lost. Ours went in for its first service so I took off the boxes. The tune box was one thing, but the missing pedal box was something else! The Q3 loan vehicle completed the reality check. SWMBO wasn't impressed either.

    Well I bit the bullet and had the DT-UK box installed this morning, running on Map 2 minus 1 at the moment
    I'll up it to Map 2 Zero for the drive home and see what that's like, you can definitely feel the power difference, car feels much nicer to drive.

    Please tell me about this pedal box and why it's a good idea?
