Excellent Driver's Car

andre1966, 04/17/2014
2014 Audi S4 Premium Plus quattro 4dr Sedan AWD (3.0L 6cyl S/C 7AM)
2014 1st REVIEW - I am now on my third Audi and my current S4 is certainly the best. I test drove all models excluding A8 (can't afford it anyway) and S4 drives the best. Especially in its Sport mode - what a thrill! You can make it a normal commute car and join thousands of other generics on the highway during rush hours. But you can put in more aggressive mode and enjoy a proper sports … car at a press of a button (well several buttons anyway). Brilliant design, excellent engineering and great execution. ----- 2017 2nd REVIEW - My first review (see above) was written 3+ years ago. Well now I owned this car for 3.5 years. It is an excellent driver's car indeed. Engine is simply superb, smart technology and very thoughtful quality accents are everywhere, car software is perfect. It still drives like a dream. I am very happy with my purchase. Love the quality and reliability, love the intelligence and absolutely love the speed and acceleration. No breakdowns whatsoever in 3.5 years and 56K miles. However maintenance cost is way too high if you don't do it yourself. I decided to do as much as possible myself (I like working on my cars) and after some initial investment in required tools my son and I already changed oil, breaks, disks, sparks plugs, filters, etc - everything strictly according to the maintenance schedule and AUDI torque specs. We use only OEM parts and save about 60-70% compared to our local dealership price. We also had to buy a special cable to re-program the car, reset service reminder, etc. I actually love working on this AUDI, it is very well engineered and it is a pleasure to service it. There is one more thing to know / consider. You should not expect this car to be very economical fuel consumption-wise. It all depends on how you drive it - you can get anywhere from 15 to 28 MPG on a highway. Once you floor it, your MPG drops - but the thrill is very well worth it. Highly recommended to those who like quality, sophistication, reliability, technology and speed. This S4 delivers all of that. Good job AUDI! 2019 3rd REVIEW - I now have almost 85K miles on the odometer. Still truly enjoy driving my S4 every time I am behind the wheel. Superb, high quality and very reliable car. Very fast, very sporty and responsive. My car still looks like new and I am not going to get a new one any time soon. I always precisely follow recommended service schedule (everything by the book!) and so far I had no problems except for one issue. At around 70K miles I started smelling gas around the vehicle. I run diagnostics and it showed misfire error code in one of the cylinders. The problem was fixed by replacing all 6 ignition coils - I did everything myself in about 20 min. After some on-line research I found that this seems to be a well-known issue - my suggestion would be to replace all coils every 60K miles. Otherwise no problems whatsoever. 2021 4th REVIEW - so far so very good. No issues, scheduled maintenance only. Recently had a road trip across the country, car performed very well and was large enough for comfortable all-day driving. It is now 100K miles + on my odometer. End of 2022 5th REVIEW - after noticing some minor noises coming out of front suspension at around 105K miles, I changed suspension components in the front myself, properly following original Audi service manual - took me three days but everything was done 100% accurately and carefully using original parts and new bolts and nuts. I had PCV-related code when I diagnosed the car recently, but the code was “unconfirmed” so I just cleared it and it did not show again next time I read the codes. I don’t drive it much these days, but when I do I am still very happy with the car. All maintenance is done according to the schedule, hopefully that will make it last 200K and beyond. The car is already 9 years old but still looks like new! 2023 - here we go, I sold it after 10 years and 115K miles. The car is still like new, and its new owner is very happy. Here is my verdict on this vehicle - it is an excellent and very reliable car as long as all scheduled maintenance is done right. If you are thinking about acquiring this car, I would suggest to check service records and make sure it was maintained properly.
