Hello guys, For those who know me and my story, my S4 is finally fixed, it was in limp mode for some strange reasons, but a great mechanic succeeded in getting it as it should be! Today I was driving on the freeway and an A8 4.2 TDI overtook me, at around 100mph (160kph), I was driving normally but ...

Then after they are going to sell a lot of RS5, they will come with a 5.2 bi-turbo, same as they did with the R8. In my opinion the earlier RS6 was better than the new one (even if the new one has a stunning look!), because of the turbos on an engine that already produced 300, 335, 340, 344, 360hp o...

Is it possible that the MAF is the source of the problem ? Because these last days (when I was testing the car intensively) the car would start to "cut" or "struggle", let's say it's in neutral and the rpms are switching from 400-900rpms, and today if I would put my foot down (even in neutral) the c...

Should I check the Coolant temperature sensor, O2 Sensor, wiring of the EPC circuit ? Where is the charge pressure control device ?

Thanks

I checked everything, and concerning the engine data, the following faults appeared : 18084 - EPC Warning Lamp (K132) Circuit : Electrical Malfunction P1676 - 35-00 17965 - Charge Pressure Control : Positive Deviation P1557- 35-00 17777 - Cylinder 5 Ignition Circuit : Short to Ground P1369 - 35-10 -...

Yes, I checked the error codes (not these days) but I didn't drive the car for a while and the problem is there since a long time. I will do it tomorrow just in case. But the noise at idle seems to be normal (I will try to record it). We put a new filter, set the MAF correctly and it still can't get...

We put the air filter out... it's dirty and seems that air can't go through... so will change it and see what happens. Do we all have such problems ? I love those cars, the RS4, and the others, almost perfect, but the quality of engineering in the electronical compartiment doesn't seem to be top not...

I've got some interesting news. Those who read my posts in the past probably know I have had issues with Limp mode, turbo leak, throttle body problem, gas pedal... Then, I changed everything, even the MAF so I thought everything is perfect right, probably because an experienced mechanic installed th...

I did it today, what kind of sound should I be seeking for ? If you're thinking about the pistons in the cylinders making a "click" noise, I think there isn't any. Okay I will do a FATS time test as soon as possible, I prefer this than hitting top speed. But even though I changed the MAF and some ot...

thank you blue thunder. It is possible that I'm getting too hard on that car... it has only a remap but not 400 or 500hp... Everybody says the car is a "monster" ... Where I live fuel has low octane so I got to add octane booster (which I didn't do these days and maybe that's why I think it's going ...

If this is an important detail I can move the fan freely when the car is cold, engine off...

I have changed the viscous thing (dont really know how you say it in english) recently, and its possible that this sound has been noticeable since then.
.
so should it be seized or not?can it affect performance? thanks for your help maybe that is the issue.

Hi, I noticed a strange kind of sound/noise when I start in first gear, maybe it's also noticeable in second gear. You can also hear it in neutral. Its the kind of sound that reminds me of a car that overheats (you know when you drive in town, when traffic is jammed and you engage first gear and put...

Hey Dippy thank you! To start a TBA I should just turn the key "on" but not that far to turn the engine on ? I bought another pedal, new one, because the mechanic thought that maybe the electronic was damaged due to humidity. I think the car is going better but really not that much. I looked for S4 ...

I did a diagnose today, the car has a fault that I can not reset. It's in german : "Fehlerlampe für elektr. gasbetätigung-K132 elektr. fehler im stromkreis" This has something to do with the gas-pedal electrical signal. I searched on the net and I'm not sure but it may be related to the EPC, elect...
