View Full Version : EVO Long Term update of the S5 nirad 12-20-2007, 05:40 PM <ul><li><a href="http://www.evo.co.uk/carreviews/evolongtermtests/211974/audi_s5.html">http://www.evo.co.uk/carreviews/evolongtermtests/211974/audi_s5.html</a</li></ul> Quattrings 12-20-2007, 06:29 PM nirad 12-20-2007, 06:53 PM DaveLew 12-20-2007, 10:03 PM Interesting observation from the article: "...pulling smoothly away from a standstill is far harder than it should be. This is a little bemusing, for while it's possible to make consistently seamless up and downshifts once on the move, the throttle and clutch are horribly jumpy when pulling away in first gear." I thought it was me and my throttle/clutch work, but no matter what I do it seems that there is a noticable jerk when pulling off. When trying to do a quick acceleration the jerk is to be expected, but at low-speed it shouldn't be there - in trying to avoid it I have even stalled a few times. As it states in the article - there is no such jerk in any other gear. Two questions: 1. Does anyone else notice the same thing? 2. Could this be the "clutch" issue that is causing for "build constraint"? JasonS4+Festicle 12-20-2007, 10:05 PM I wondered if it was just me. I've been driving manual for 20yrs and have never had this issue. nirad 12-20-2007, 11:16 PM that concerns me, as i live in LA. I don't want a car that is difficult in stop and go. snow day 12-21-2007, 03:24 AM ...when I test drove the demo at our local dealer. I was a little surprised at how touchy the clutch was when starting to release it. I thought, hmmm, I'd be able to adjust my technique if I had some more practice, but I've been practicing for more than three decades. Despite the clutch behavior, I ordered an S5 anyway. Folkie 12-21-2007, 04:35 AM I tend to start off in second gear much of the time. This is considerably smoother, albeit with less pull. Quattrings 12-21-2007, 06:19 AM quickly enough. It is rather annoying though and almost like the car only takes off smooth out of first if your driving fast. I like to drive fast but not every time and it shouldn't require having to slip the clutch to make a smooth start possible. Any other gear is fine though. Quattrings 12-21-2007, 06:23 AM Speeds were slow enough that I couldn't shift to second or I would be going too fast, so I was required to keep it in first and then let off, repeat. I think it may simply be a software issue like the article says. The ECU might be set to be too responsive to throttle position and in first gear that makes it difficult. I'd bet a memo to dealers will be out for a reflash at some point. JasonS4+Festicle 12-21-2007, 06:42 AM the clutch VERY slowly without any gas, you'll notice the car will take off slowly without much RPM change. I believe this "anti stall" stuff is built into the ECU. maybe there will be an update. Quattrings 12-21-2007, 07:32 AM I've seen the engine RPMs throttle itself to approximately 1000RPMs, 2-3 times during a couple of idle situations. It seemed to be correcting a low idle, but it didn't seem as though it was that low to begin with. Europa 12-21-2007, 08:01 AM This could be due to choosing to use a lower-mass flywheel, or maybe a stiffly-sprung clutch plate. It's likely not the mechanical problem that most cars have reported, however, since it seems more like a characteristic of the car than something that would lead to a flaw. The demo vehicle at my dealership blew a clutch slave cylinder within four days of the car's arrival. JasonS4+Festicle 12-21-2007, 08:02 AM JasonS4+Festicle 12-21-2007, 08:33 AM some grunt to operate (VERY stiff) and I can take off smoothly without any difficulty. This issue seems to be computer related IMO. Europa 12-21-2007, 08:47 AM ... clutch friction plate. You make an excellent point about this possibly being computer related, though. JasonS4+Festicle 12-21-2007, 09:41 AM FinallyS5 12-21-2007, 11:17 AM Tal-Yvan 12-21-2007, 11:39 AM Not a biggie tho, it's like a small jerkiness but i'm used to it now. I did notice, and actually i felt like a noob driving the demo, i though it was because of the difference in the travel between the S4 and the S5 cluth. Europa 12-21-2007, 11:49 AM Quattrings 12-21-2007, 11:53 AM yellojello 12-21-2007, 02:48 PM yellojello 12-21-2007, 02:50 PM vortexx 12-22-2007, 10:11 AM That sounds like it could be the air conditioning compressor cycling on and off at idle. Quattrings 12-22-2007, 07:50 PM brokerjoe 12-23-2007, 01:22 PM Sounds like it is a software issue all a long because you guys are having the same issue from manual transmissions. I kept complaining that from a dead stop the car would herk & jerk from stand still then finally feel like it "engaged" into speed. That was annoying!! And this is coming from an automatic transmission A6. jba 12-23-2007, 01:28 PM I can't believe that audi has yet to fix this issue since the B6S4. The inability to drive the 6MT smoothly despite driving a stick my entire life was one of the reasons i went w/ the tip. I've loved the tip, but always thought i'd eventually be back in a MT audi. This news is inexcusable, IMO. I don't get it. nirad 12-24-2007, 07:31 AM jba 12-24-2007, 02:36 PM JAMR S5 01-10-2008, 07:09 PM Got her less than a week ago. Thought someone pulled up near me and was revving their engine...it was "Claudia" and she was in neutral!Happened again and am adding it to my "cons" list. |
