Car is still running great - I ran a fault check in VCDS and nothing to speak of besides a Rain/Light sensor fault about 600kms ago (last Tuesday I'm guessing). The engine was stuttering a tad when I started it the other day (had the radio off which is how I heard it) - was probably just cold, as it was gone after sitting there for 2 minutes. I didn't realise how low the RPMs are when it idles (I think it went from 2200 down to 1100 or thereabouts).
I washed it yesterday and really want to drive it, the problem is that 1) the front will get splatterred with more bugs, and 2) I've driven all the great driving roads around my area multiple times. I might have to resort to playing Test Drive Unlimited on the PC again
It would seem there's a few levels of sportiness (in D mode)
<> Stock (Program One)
<> APR - you can hear the extra exhaust noise but not that much more response/power/torque
<> APR - fairly punchy
<> APR - absolutely mental acceleration
So, a modern car with a stock ECU tune will also produce varying power depending on conditions - especially if it's turbocharged. Temperature, humidity, and many other inputs from vehicle sensors are all going to have an inpact on how the car chooses to run boost, ignition timing, and fuel mixture. Flashing with an APR (or any other) tune doesn't change this - the car still needs to run to the conditions.
I doubt it. Possibly due to how I interact with the IGN though. But again unlikely. Maybe just a faulty component.
It hasn't been to VW only because the car is in MELB and I am about to leave PERTH to fly to Brisbane.
When I return to MELB I'm going bush so again. So the reason for the delay is purely convenience.
Hey logger. Do you feel that the IGN fault is something that you've caused with one of your other mods (lights etc) or VCDS changes? I'm just wondering why you haven't just dropped it to the dealer already...
Really thought it was sorted this time Logger.....
Well it is more or less sorted. At the time of the previous fix I had just identified the cause of the fault. Have not gotten around to fixing it yet. So will keep you updated on how that goes.
Keep in mind that the cause of this IGN fault is not caused by the tune in any way. The behaviour I see is mirroring what is supposed to happen with APR tunes if you were to pull the battery lead. As far as I am concerned the tune is working as it is designed to do.
The issue my car has, would also generate a fault and would probably ultimately cause issues even in a car without the ECU tune. Once I fix the IGN problem I expect the un-commanded switching will go away.
Allow me to balance out the equation here - I have not for a second regretted spending the money on the upgrade. Sure, I wish the performance was more of a constant than a variable (or at least more predictable when ummming and uhhh'ing over whether or not to overtake someone on a two-way road, but I did the unthinkable and chose Program 1 the other day on a short trip to the petrol station before a cruise to Mt Baw Baw - and the difference is still very noticeable. Most of the time the car is in the 'punchy' range. I've recently started using Manual mode more now (now that I'm used to which way the +/- are facing), and it's yielding very nice results - more powerful than D due to holding the gears longer, but at the same time can be used in traffic without looking like a complete hoon as is usually the case with Sport mode).
So yeah - if you can budget the Stage 1 tune - just do it.

I know that my car is always in Program 2 because there's no lag when moving from a standstill.
Thanks. Yes it is a relief to know it is the car playing up and not the tune.
Coincidetnally - Driving back from the bush last night, I noticed the tune had spontaneously quit working again. So I hooked up VCDS and sure enough the same 4 Ignition Switch fault messages had re appeared. So some time in the past couple of days this recurring IGN fault cut power to the Engine ECU, resetting the APR program to stock again. I re-selected APR Prog 2 (98 Ron) and all is back and working again.
It may be that I need to get the electrical side of the IGN switch replaced to prevent this recurring. Will also see if there is a pattern to when this fault actually occurs. Seems unlikely it faults when I am operating the the car. Would expect to see things happening as the IGN switch gets 4 x "Fault in Circuit - Intermittent" events on seperate terminals. Especially as it is taking out the Eng ECU. Could be to do with my idiosyncratic operating procedures with the Ignition switch, when the car is parked. Will investigate and report back.
Oh nooooooo

If anyone can get to the bottom of this, my money's on you, fingers crossed.
I am considering APR Stage 1 tune myself....hence the main reason for reading
this thread, nothing like feedback from those who have gone before me.
Keep us posted pls
Have just finished reading this whole thread.....phew!
Your posts were very informative and as I read them I kept hoping for a favorable outcome regarding the issues you were experiencing.
Sounds like all is now good with your 118 TSI so just wanted to say that's great news and you must relieved

You know how what I just said a couple of hours ago. Not taking anything back, but I went to grab some take away and the car was ferocious in it's response to the accelerator (I nearly flew out of the driveway (it's uphill)). Still haven't touched the cruise control stick.
I've had my Stage1 tune for over a month now and the only times it's felt like it was "dropping out" of tune was in the first week after I had it done. Very odd. It was 40C in Perth today and it still felt like it was pulling hard. I'm continually amazed at how much torque it makes below 2000 rpm after the reflash.
