MTM seem to have a whole package but I can only find the map on their website. Not sure if one of their exhausts are in this video but it's much more meaty https://youtu.be/WD1i1VCJVz4

Miltek are also working on an exhaust but it hasn't been released yet.

Just watched the video interesting the first proper video i have seen of an exhaust system for this engine. I have seena teaser video of some revs for the milltek exhaust on their instagram page. That will be my next and last mod 😂

Another video of an Armytrix system on a B9 A4, so i'm sure a B9 S5 will arrive shortly. Sounds pretty dam good on a 2.0lt, so imagine an S5 offering!! Ignore the stupid 40 TFSI badge though, not sure what's going on there. https://www.youtube.com/watch?v=Cgq05eoFmGI

Which chip have people bought then?

This one https://www.tdi-tuning.co.uk/car_and_van_petrol_tu...354_ps260_kw/audi_s5_30_tfsi_quattro_349_bhp_354_ps_260_kw_crtd4_sent_multi_channel_petrol_tuning_box_chip_P13859.html

Or this one?

https://www.diesel-performance.co.uk/vehicle-audi_...

If the engine breaks / fails because of the chip surely Audi would be able to tell its been running higher boost? Wouldn't they?

The chip intercepts the boost signals and presents them as lower to the ECU, ECU then sends for more boost etc, so higher boosts are not logged, although higher EGT's etc may be logged if logged at all.

It's not a "chip" really, it's external module that plugs into the wiring loom and sends fake sensor data to the ECU.

Obviously it would depends on how the engine breaks, but they'd probably have a pretty good idea of why it might have failed. Tuning boxes won't set the TD1 flag in the ECU (unlike a remap) but even trivial stuff like damaged/rearranged connectors could send them scurrying towards your social media posts.

The problem is that regardless of evidence if they just say "nah, ain't gonna fix it", what then?

I'd say the risk is very low, but the consequences aren't pretty - doubly so if the car is on finance/lease.

The addition of a pedal box may be useful to get over the first big down on acceleration. What I have been doing more recently is applying the handbrake at a stop as it seems when you floor it, it overcomes that initial laggy moment you get. (Maybe I'm putting wear on handbrake shoes or something doing it this way though???)

I have one fitted previously on an SLK for 40k miles with no issues at all. Even with minor warranty repairs and dealer servicing. Car was returned over a year ago and nothing since. This is why I opted for another as in my mind they are tried and tested, do the job, can easily be removed without trace. Dealers are not detectives and certainly would not scour all the 1000's of threads on hundreds of sites looking for a clue to a potential chip user. As for the plugs, they are not sealed so why on earth would they suspect a chip as a culprit?.....There is no thread on any site that I have seen blaming a chip tune for engine failure, or indeed dealers blaming a warranty repair on a chip tune. It's entirely up to the owner wether they want to purchase one or not and for whatever reason, but if the reason is because you are worried of being 'found out' then don't buy one as the worry will obviously be too stressful as opposed to the performance benefits gained.

I am by no means an expert on any of this but - on a lease I am ok with fitting a plug and play device such as the tdi box or a JB1 like I installed on my Golf R. These do not flag the TD1 code. An ECU flash by someone like REVO is not something I would do as this does flag the TD1 code.
To my basic knowledge such a code would get noticed at the dealers but if it doesn't come up they wont do any further investigating. Some dealers wouldn't even care about a TD1 code or other mods others would.
When my Golf R went in for a service i removed the JB1 device and re-connected afterwards with no questions from the dealer about the cable ties etc in the engine bay. My lease was returned in mid Dec and since the car has been auctioned off and sold by a dealer in Preston and no have come back to me. not surprising as it doesn't flag an error code.
If you are worried about fitting one dont fit one - it will just niggle away at you in the back of your mind. but think of it this way - companies like tdi tuning wouldnt be operating if cars fitted with these devices were blowing up etc.

Ah ok. Thanks for the info. I will probably not get one but any thoughts on the company to use?

TDI Tuning. On setting 6 it goes like rocket. BTW, the chip 'fooling' the ECU is an incorrect description as is any 'possible' EGR log. Don't let people put you off who have no real knowledge of how the TDI unit works.

Recordings please

[dufflecoat]

So it happened. The missus has scuffed an alloy on her second drive, less than 2 miles total covered in the car.

Small scuff, 4 cms and probably 0.5cm into the wheel. Its on the "shiny" diamon cut(?) bit. Any ideas on how I could bodge it up/make it look better?

Reluctant to do anything more as will cost a lot and she will be driving it again :/

Ask for Simon Hill when your there. He will look after you.

Heartbreaking isn't it. I don't let my wife drive the S5, she has a Mini of her own to mess up. We used to share a new Land Rover which she crashed twice and if you saw the alloy kerbing you would cry. Danger is if you repair it, it will happen again so maybe just refurb them once a year.

I would not bother is she is going to drive it again and just sort them before the lease goes back.

Might not be going now - called LV insurance to tell that about the box and they do not accept tuning boxes or re-maps etc. So I either swap my insurance or dont go for the box. Tempted to swap insurance just on the basis of LV being ars**oles.

That's mad!!....my insurance just noted the make on the policy and without any extra charge. If you are referring to Liverpool Victoria I'm not surprised. They refused to insure a LH drive vehicle I had a while back, only because it was LH, no other reason. TBH, if you ever claimed with them I recon they would be a real pain in the a*se.

Maybe put some alloy gators or rim blades on... have them in my Mrs a4. Can't Notice them if you out them on properly and may cover the scamtach plus protect them from further bumps

More TDI Tuning info..........

I am having my TDI tuning box map 'tweaked' to better suit my personal requirements. If anyone is interested, here is an email in response to a few questions:

Hi Ian,

Thanks for your email. As I am sure you can understand, the finer detail as to how our devices Read, Decode, Interpret, Process and Re-Encode data from various sensors across the engine is closely guarded intellectual property; and because of this we can not divulge too much as to in-depth inner software and hardware workings of the CRTD4 SENT system. However I can certainly clarify the most fundamental elements of the CRTD4 SENT system for you.

The CRTD4 SENT system is packed with functionality which has been incorporated to cover an extremely wide range of vehicles. We activate the hardware features for each vehicle as and when they are required. This feature allows us to be able to offer you equipment which can be re-programmed and customised to suit thousands of different Petrol & Diesel vehicles. Ultimately, your CRTD4 SENT system will continue to provide you with extensive returns on your investment for many years. When we build our tuning files for each vehicle model, we build the files so that they can take advantage of the parameters which are available on the ECU. Essentially these parameters are deliberately left open for modification by the motor manufacturer. Motor manufacturers have to build a wide number of engine maps into the ECU in order suit an extremely wide variation of variables such as Fuel Grade, Altitude, Air Temp, Engine Load etc… With this in mind, we are able to activate other configurations which are already stored on your vehicle ECU. – Please be assured that this may sound simple, but the process of doing this without leaving history or permanently modifying the data on your ECU is complex! Ultimately, we are guiding your ECU to make the changes to Fuelling, Boost, Timing etc that we want in order to provide you with the gains physically achievable by your vehicle. Please be assured that everything involving the software on our products have been produced to suit your March 2017 S5 3.0 TFSI 354PS. – Unlike most other companies out there, we don’t buy products from other companies and stick our label on it!!

It is worth noting that the term “Tuning Box” is widely and commonalty used to describe many types of product which “Connect” to the vehicle via the engine bay. Unfortunately the important details of high powered technologically advanced digital control systems such as ours are often over shadowed by “Sub Standard” products on the market offered by other organisations which fall way below par. Those products unfortunately do a good job of tarnishing the industry as a whole. I can categorically confirm that our systems are not the same as supplied by other companies on the market, unless they are either an approved TDI Tuning Dealer or one of our approved white label dealers around the globe. We design, engineer, develop and retail our own hardware & software which allows us to develop equipment which has been directly inspired by client demand and requirements. The maps for your S5 for example are the product of extensive testing and feedback from our development team in Essex. That said, because our products are fully customizable, we can certainly personalize your maps for your individual requirements as per your email below.

We are open Saturdays but need you to confirm a booking slot for when you would like to come across. I hope this answers your question and if you require any further information please do not hesitate to contact me.
