If you want howling and whooshing you have a few options, mostly around air intake to allow more induction noise, that or buy a wolf?

It is! Like many things in life the devil is in the details. The auto industry learnt a big lesson from the Boeing 737 max disasters. No longer can they be allowed to self regulate, which is where autonomy was headed!

Thanks, though this will be the 5th VAG car I've remapped, everyone of them in warranty, 4 still in original manufacturer's. This will be the 4th that I've asked permission of both the relevant brand technical and financial team to do it, as the first I bought outright with cash. Hopefully it won't be the second with turbo failure, though that was replaced under warranty because I'd followed the above procedure. You're right though, if you can't afford to replace the broken parts, don't do it. However, the most important consideration if its a financed vehicle that you don't violate your contract, so ask them first, otherwise the bill could be much larger than just the cost if parts. Read the breach of contract clauses etc etc

The issue for the ECU is that the sensor data will be likely be different, so different tables etc. I'm guessing most new car models have a 3 sigma of +/- 2-3$ around stated nominal, so 5bhp will bypass the bum dyno easily

Adaptive cruise control is a good example of the limitations of the technology. It cannot learn to spot new hazards over time, it either works, or it doesn't. That's where transport is right now wrt to adaptation, it doesn't. The legal and social implications of permitting it are not to be under estimated.

These are still adaptive / passive systems though. None of them will assume any form of direct control over the vehicle, you operate the device in 2 dimensions as we always have done, velocity and direction. They merely change the efficiency of the device. I think the confusion with "learning" is the inherent concept of time. The engine will "learn" that is has a new fuel rating within milliseconds of it appearing in the cylinders, so the myth of needing a tank or two of 99 RON for the car to become faster is nonsense.

See xman comment below, adaptive is absolutely the right description. Adaptive though in current architecture from a performance and safety POV is usually measured in ms, and ideally even quicker. Yes, just like humans. Machine learning as a basic principle requires the process to run many many times, with the inherent variations to be registered and accounted within the model. The issue is whether we're prepared to treat a car as a child for example, with all of the issues and compromises that that brings. That's massively oversimplifying it, but it gives a good idea of just how complex autonomous vehicle design is / will be. Arguably the sensational media question about who does an autonomous car kill first in a crash, answer is like the aero sector we design out errors, as the contract with the user psychologically changes significantly. We all get into our cars every day, and knowingly take risks, sometimes ones that we know are potentially lethal. no one ever got onto a commercial airline flight ever expecting to die. Absolutely. My day job involves confirming that the input data, and the output instruction is what you expected, so trying to remove the subjective interpretation.

There is no AI/machine learning code of any sort in any car sold in the UK today. We're only at level 2 autonomy with Lane departure warning, we're a long way off L4 or 5 that would make use of that kind of AI. Every sensor on a car today is a fixed calibration / response, and the control units issue instructions against a fixed set of conditions, the only "learning" it does is respond instantly to changes on the sensor inputs, eg fuel RON antiknock. We are a number of years away yet before any form of machine learning code will be certified for pass car use, we've not even managed to get the fixed state sensor networks accurate enough yet, witness the occasional accidents that teslas have had.

The price SCM quoted would have been for an APR map, so definitely not cowboy with a laptop crap. That's why it was so much, same price for a stage 1 for my octavia. You'll get a similar response from revo dealer, generally you get what you pay for. Personally I'd rather spend a few hundred quid on a 20k plus knowing that it's been properly tested and validated.

Some years later.... They've definitely upped their game. I've just bought my second car from them. Had some issues with a superb that I bought from another dealer, which they fixed at a mistakenly lower cost than it should have been and honoured it. The garage service has been vastly improved, I don't think it's any better or worse than any other main dealer. I get on well with their service manager, over the last few years they've always looked after me.

I've been disappointed recently, calls not returned, so so attention. I've just bought my second Skoda in 2 years from my local dealer in West Wales.

Resurrecting this - has anyone else done this with a 245? I don't have immediate acces to VCDS but would consider tracking someone down who does if the results are sufficiently beneficial!

Had one on a Tdi VRS Octavia, replaced with a proper remap. I wouldn't bother again with a box tbh.

Looking for a quality remapping service in west wales, so quality over price. All of the big names are a fair drive away, and I'm not sure I want / can do it remotely anyway; though I have done in the past with a Shark STS system. TIA.

Is it stock or remapped? I'd only be guessing at the reasons tbh, have you tried a different driving style? Might be worth noting the EGTs off the app, mine were always around 550 Deg C during an active regen, and would need to be around 450 minimum to do a passive one.

Anything between 350km and 550 km. Occasionally it would self regen as it were under load uphill if the gas temps got high enough, but that was quite rare. Tbh, the app should be something you should use if you're driving a diesel, as it will indicate the cumulate ash collection, so you'll be able to monitor the life expectancy of your dpf. It's worth bearing in mind that it's not actually measuring the ash production directly, the values are inferred from a bunch of other sensors, so it's possible that after a remap, the algorithm is assuming a state inside the dpf which is inaccurate. At best this means more frequent regens than required, much worse is that it doesn't do it often enough, and then you'll only realise when the dpf pressure sensor warning is activated as it's full of soot. Not heard of that being a problem mind you, and I searched for a while on the subject at the time.

I asked the question specifically of the seller, and they are certain it's not fitted. The issue is restricted flow, even in standard tune, most of the VAG models are 5bhp lower in specs post GPF intro.

Never mind the bhp figures (after all who uses Vmax anyway in the UK), how do each of the engine variants respond wrt torque, as that's what provides the real thrills ime.

I had a VRS TDi same colour as yours, also remapped, and agree, it's not a particularly fast car. I couldn't get anywhere near 50+ mpg, 45 was a good result.

Typo in my original post. It will generate more ash when it's using more fuel, but it's an accumulation, so unless you accelerate to a higher speed every time, then you won't be using more fuel (in fact my mpg improved). probably a bigger factor will be around the quality of the map and how well it manages air flow to fuel rate.

Interesting thread - I've just acquired a 19 plate octy 245, which does not have a GPF fitted. Don't know the engine code / exact build date etc as now actually picked the car up yet, but my plan is to keep it beyond the pcp, plus I will be covering a big mileage, around 30k a year. From what I've read thus far, I shouldn't expect a higher rate of carbon build up on the basis that MPI was used until the WLTP tests were introduced that drove the requirement to switch to DI + GPF?

Full background, I also had a DTUK box on it for a while prior, but got fed up of check lamps and limp modes, so went with a local tuner who installed a Quantum Tuning map. I initially thought that it triggered a much shorter regen cycle, but we ran it map on and map of with the DPF phone app monitoring everything, and found it to be no worse than stock. EDITED - it was NO worse than stock not NOW!

How west is west? As in how far from Haverfordwest?

Thanks for the info. Yes, I searched for BCM, and figured it's the controller for the interior electronics architecture, so essentially another ecu. Presumably just means you can unlock some other features using vcds or whatever it is these days. Traffic sign recognition etc, though not sure it's worth the hassle?

Indeed, surprised me too. I doubt it would be the same response today.
