Poor performance?!

[dasquade]

Personally i have obdeleven (around 65€), super user friendly, leave the dongle in car and connect with your phone.
About the golf, engine numbers are one thing....weigh difference is an other ....but clearly something is not performing well on your car apperently (checked airfilter?).

Oh guess you are on to something. YES boost gauge should go all the way till the top....and ideally hold it boost between shifts.
Failed turbo sensor only have me half bar, vacum leak aswell i think or maybe the lack of holding between shifts.

Ooo..OBDeleven looks interesting!

Mmm..I'm going to check, I think my boost drops to a quarter if that on gear shifts.

Many thanks all for your input, I have much more info and knowledge now!

It can be anything tbh...
One issue i once had was....i had 1 of the 2 turbo pressure sensors malfunction. It didn't throw a visual code (check engine light for example) but once i read the car with obd scanner it showed up. Car wasn't making full boost and felt lumpy. A quick visual indication was....since it was a boost issue, the boost gauge in the lap timer.
But like said, can be anything. Not sure if it are the spark plugs tough, that would more give you misfires (feeling as random power cuts) and if there are too many misfires you would definatly get an check engine light error (some misfires are common, hence why audi only throws an error once there are xx amount of misfire in xx periode).
Could be a vacum leak aswell, won't show up in the display but most of the times if you scan the car.
Imho, get yourself obdeleven dongle/app so you can scan and live log the car....or leave it to the 'experts' (dealer).
Unless the golf was high tuned....
No real need to dyno it, you can actually log with scanner how much torque the car is pulling (with obd11/VCDS scanner that is).

Re dyno run, that would only cost you £60 - £100 anyhow so hardly a big deal.

Hey all,

I've had the RS6 for about 3 weeks now and before I purchased, I read about watching out for hesitation and lag especially during the test drive.

Over the last few weeks, I've been feeling a hesitation from the car but I thought it must just be me getting used to it.

However, tonight I was joining a motorway ( gear in sports, and auto mode) and a Golf R Infront was just pulling away gracefully ?!..

I was scratching my head and reading up on several things and have owned a golf before and looking at bhp and torque compared to an RS6...even chipped, doesn't get near a 6! Supercharged Golf only hits 480 or so BHP..

Am I missing something or am I experiencing a dreaded turbo failure? Anyone around the Standsted area that is really familiar with the car?

Many thanks!!

You could get it dyno tested ? Get car logged on road before and after dyno too

Good idea. I'll see what the dealers say first and I might get it dyno'd. Any recommendations down south?

I may be heading up North this weekend also and read some good reviews on awesomegti?

Re AwesomeGTI, everything you need under one roof.

I didn't notice when my turbos were going it was still pulling like a train, I got a warning light on then i got them checked and yes they were on their way out, Car is in just now getting the turbos replaced and the strainer, The weekend before i took the car i was racing another RS6 and was pulling away so i think his turbos must of been worse than mine!!

How many miles had your car when turbos started to fail?

[k5vmc]

Am sitting on 40k now i couldn't tell you when they failed as i had the car a week and went MRC stage 2+ Friend of mine got the Waring like of low fuel pressure on his dash and got it checked out and i was on my way home from dropping his car off to get fixed and mine came on. I never suspected the turbos as it was still pulling strong. Am not easy on my car so i went for new turbos and replaced the strainer at the same time, Friday can t com sooner.

Can it be because of ecu remap and stage 2? As we all know car has more power then it tears apart quicker, of course some of our technicians in here will say otherwise and they state that ecu remap doesn’t affect anything.

There are also more mundane possibilities. The car is designed for super unleaded. Standard unleaded will knock a good chunk off the urgency of the engine. I also find that, even in kick down, the car is less urgent in Comfort (or even Automatic) than it is in dynamic.

Set everything to dynamic, run the car with a tank of Tesco Ultimate, and drive like you stole it down a country A road. If it doesn't frighten you witless, then - yes - there is something wrong with the engine or your threshold for danger.

Nah standard cars are having the same issue, Its the strainer that is blocking is causing the issue, And that is the chance you take modifying your car!

Offcourse a remap, and especially going to the limite, will cause earlier break down. What i silently was affraid for was recently confirmed on audizine by some.
Some maps pushing the turbines to their limites and can over time become so stressed out they explode (with no running hot/broken shafts but purely the turbine)
->overspine of the turbo. God knows untill what boots you are playing safe but offcourse time and how much you pushing it all mathers.
So it ain't all that simple to classify them all under the 'ohh it was just the known oil strainer'.

[uplandsway]

There’s clearly as many stock cars vs modified cars having same / similarly related issues..

People just jump on the bang wagon and are generic with there opinions and statements

Stock car in warranty with similar issues you have a chance with Audi coughing up

Modded car your on your own but majority of modded RS6 owners over maintain there cars anyhow and don’t just service when dash light goes on or they get a reminder phone car from Audi

Perfect mate nothing lasts forever, If i didnt get them check i would be non the wiser there was a issue as it still pulled well. Best getting your checked out and keep us all posted what the findings are. Is your RS6 standard?

[W8PMC]

Not wishing to play the 'don't dis a Golf R card', these cars really shouldn't be underestimated.

Mine although only Stage 2 (with hardware) so pushing out about 410bhp, will comfortably & repeatably hit 0-60 in 3.2/3secs & although it will start to run out of puff once well over 100 & a C7 RS6 would pull very hard from North of 100, if only a quick race then a lightly tuned Golf R would give an RS6 a very good run for its money.
