    "Fidgety" acceleration

    I have bought a A7 3.0 bitdi from Audi which had stage 1 remap by previous owner. If I accelerate hard, in the first 1 second or so the car feels really fidgety and wants to pull hard to one side or the other. This stops after a second but I have to watch out for it when first putting my foot...

    Start/stop system fault

    Because the fault had been occurring for the 3 months since I bought the car from them, they replaced the battery for free. However they originally quoted about £420.

    Unknown A7 bitdi mod

    I've been sold a 3.0 bitdi 2014 A7 by Audi in December. While having some work done at audi they have just told me the car is chipped. I don't know when or by who or what was done. Audi can't tell me but have offered to put it on a dyno to compare with stock figures. Will this help or will...

    Insuring an unknown mod

    I've been sold a 2014 A7 by Audi in Decebmer and just found out it has been chipped. Don't know when or by who and Audi say they don't know. This means my insurance is invalid so I need to declare the modification but have no idea what has been done. Any suggestions please? Audi have said...

    Start/stop system fault

    I had an issue like this for 3 months with my 2014 A7. After going in and out of Audi and few times they finally said the battery was poor and replaced it for me yesterday. I don't have the car back yet but am told it is now working fine so 5.5 years would seem about right for a battery change.

    Audi sold me a tuned car

    Audi have offered to get the car on a dyno to see what sort of mod has been made but will this tell anything? Wouldn't it be comparing wheel bhp with Manufacturer quoted fly wheel bhp? So it will under quote the bhp increase? I don't know much about tuning so am completely guessing here.

    Audi sold me a tuned car

    So just spoke to Audi. They can probably reset to stock but I've no idea what the performance will be after. Looking at insurance for if I keep the remap, I need to be able to tell the insurer what sort of upgrade has been done and I don't know (and Audi can't tell me) so looks like I have no...

    Audi sold me a tuned car

    I'm torn with what to do. I'm not sure if I want to keep a car that has been remapped when I don't have any knowledge of what sort of modifications were done or by who. I've always thought that mpg was way less than expected (average 24-28 mpg on a 30 min B road journey, never see more than 32...

    Audi sold me a tuned car

    I'm going to call them tomorrow and see what they say but I want to know what to expect. 1. Should they just be able to remap it to the original map? 2. If they say they can't, where does this leave me? I have know idea what type of tune has been done, by who or how well. I don't know what...

    Audi sold me a tuned car

    I bought a 2014 A7 bitdi from Audi in December. It has just been back to them for a start-stop problem and while trying to do a recall software upgrade on the engine they told me it failed because the engine has been "chip tuned". The car wasn't an Approved Used Audi because it was just over 5...

    Start-stop fault?

    So I just spoke to Maidstone Audi. They said there is probably nothing wrong with the car if there are no warning lights. There are apparently "50 reasons why the system wouldn't operate including if the radio is on"! It's a joke. No way could Audi have designed a start stop system that...

    Start-stop fault?

    I've had it working on a couple of journeys. But I would say it has only kicked in about 5 times in the last week of driving every day. It can work so I know it isn't switched off, I'm just thinking the battery doesn't have enough guts left. If the battery is 5 years old it would be due a...

    Getting the best from tiptronic?

    It's not throttle lag I have the issue with. I have the same issue in dynamic mode and if the gearbox is in sport or manual mode. I apply the throttle, the revs initially build without lag and then drop again as the torque converter smoothly applies the power to the wheels. It is a feature of...

    Getting the best from tiptronic?

    Hi I've just picked up an 2014 A7 3.0d biturbo which I love except for one thing. I'm used to driving a manual or even a DCT where the gear is fully engaged and the power response is immediate. Going round corners I have got used to dabbing the power to pull you through if you can feel the...

    Start-stop fault?

    Hi I've just picked up a used Audi A7 (2014 black edition 3.0 bitdi) from an Audi dealer at the weekend. I don't have any fault warnings but I just can't get the start-stop system to kick in (it has actually worked at one junction but that is all). I know the car has to have enough power and...

    RS5 much more to run than S5?

    I probably wouldn't remap to avoid issues with warranty and insurance. In real world driving I don't find the S5 much slower based on test drives. The only thing I have against the S5 is that it isn't an RS, if you know what I mean. Has anyone switched between RS and S5 and found much...

    RS5 much more to run than S5?

    Thanks Theophany. I plan to get a warranty with either car and the warranty is only about £100 more expensive for the RS. It sounds like the service cost difference isn't too bad. It's just the brakes on the RS that are the killer. If I can find one with new discs then that should help!

    RS5 much more to run than S5?

    That's the thing. I'm pretty sure I can afford it but I have never owned a performance car so don't really know if I am letting myself in for a world of expensive repair bills. I am expecting about £1k for front disks and obviously more expensive fuel costs with the RS5 but will the other...

    RS5 much more to run than S5?

    Hi I am looking at getting a 2014 S5 or RS5. I would prefer the RS5 with the V8 than the S5 6VT for the sound and the more aggressive styling. I won't be taking it on a track and so the S5 is probably a more sensible choice put I am still pulled more towards the RS5. I had been put off the...

    RS5 much more to run than S5?

    Hi I am looking at getting a 2014 S5 or RS5. I would obviously prefer the RS5 with the V8 than the S5 6VT for the sound and for the feeling of knowing I have the top of the range. I won't be taking it on a track and so the S5 is probably a more sensible choice put I am still pulled more...
