So I thought I would bring this issue up and see if anyone had any comments. I have searched around here and other forums without much luck.
This is not a typical case of "turbo lag", turbo leakage, diverter valve issue, transmission or something like a bad MAF. This is what I feel is a straight up drive by wire problem due to either a bad drive by wire part and/or software problem?
History/background - 2003 New Beetle 1.8t 6 speed Tip automatic. car purchased new and reasonably maintained. Car has had EVERY standard VW/Beetle issue and all issues have been addressed.
I believe the problem is a drive by wire issue and it only occurs under very specific circumstances.
No CEL or codes showing up at this point. Will not be able to get a VAG tool on the car for another few weeks. Car starts and runs fine, gets good fuel economy behaves as you would expect except in quick off idle throttle moves, but only while you are rolling under 5-10 miles per hour.
Description of what happens - When making parking lot type moves or coming off light throttle, car still rolling and usually in 1st gearm then getting back on the throttle to merge quickly into traffic or make another move of some sort there is no throttle response for what appears to be 4-7 seconds. Engine just idles, nothing happens. If you hold your foot still, after some period of time the then engine starts to make power. I have since decided to actually floor the gas pedal when this happens to see if the engine responds. What happens is there is still no response, then once response starts, the throttle does kick in harder than if I just kept the the accelerator pedal where I would expect to typically have it for how I am driving.
This is nothing new or just started to happen. I did not drive this car daily for the first 8 years, but I did experience this a few times during the first 8 years when I occasional drove the car. For now, I am driving the almost daily and I experience this problem every few days or so. But I am now starting to see somewhat of a pattern and I am now able to predict when it may happen.
This is not a maintenance related problem, this either a drive by wire component that has been bad since day one, a tuning glitch of some sort or a combination of both.
Also this is not the first drive by wire car I have had, at this point all 5 cars I currently own are drive by wire. I have also owned and driven other turbo cars many years ago. This is borderline hazard as if you are in situation where you maybe pull out, then hesitate to continue, then realize you are committed and have to get out of the way, you are stuck with a car that will not respond. The length of time is enough to have that bad gut feeling that you know something bad is happening and there is nothing you can do about it but just wait and hope for the best.
I need to see what tools I have at my disposal and will start looking at what sensors I can monitor to see if I can narrow this issue down.
I am again just looking for anyone that has experienced this type of problem and if they have ever found a solution. Not looking for did you change your fuel filter or air filter, this and more has been addressed.
I will next try to put some tools on the car and try to record what is happening and then go from there, but thought I would ask if anyone else has felt/experienced this type of issue.
