rs6 c5 power loss and supercharging circuit leaks
Re: rs6 c5 power loss and supercharging circuit leaks
Hello again to all, I come back to her inflates me seriously she began again I replace the N75 by a valve reinforce it works randomly sometimes I have the power sometimes its push in atmospheric more turbo
Re: rs6 c5 power loss and supercharging circuit leaks
Is this happening since you put the new Mac valve on?

Re: rs6 c5 power loss and supercharging circuit leaks
the phenomenon was already the front, my N75 was tired, with the valve mac when it works it's better than with my old N75
Re: rs6 c5 power loss and supercharging circuit leaks
You need to do some logging with the Vagcom to eliminate issues like brake pedal switch malfunction, boost pressure sensor, MAF wiring, transmission power reduction requests, misfire detections.
Do you have a Vagcom?

Re: rs6 c5 power loss and supercharging circuit leaks
yes I have a Vagcom on which channels I must put myself to check these bodies to know the ignition spins I already knew the 8 coils are good no spells and new candles curiously the first acceleration often works after I lose the power it could to be the N249 I did not replace it?
Re: rs6 c5 power loss and supercharging circuit leaks
Could be N249, or a bad DV. Could be bad wiring to N75 or MAFs. Gotta eliminate causes one by one.
On the Vagcom, log groups 002, 122, 115 on the engine control unit.
Then log groups 001, 007 and 003 on the transmission control unit.

Re: rs6 c5 power loss and supercharging circuit leaks
for DV they are new, I will try to make the logs tomorrow of these groups
Re: rs6 c5 power loss and supercharging circuit leaks
Make sure you mark when the problem occurs. And do the logs in turbo mode if possible to get a higher sampling rate.

Re: rs6 c5 power loss and supercharging circuit leaks
VCDS no engine error, I did the engine and box logs
for motor about 20 / 25min after start the car runs normally before it has no power, for the box the car was working properly during the log

Re: rs6 c5 power loss and supercharging circuit leaks
You appear to have uploaded the same file twice.
Did the problem occur during these logs? I didn't see any markers. Also, the requested boost never went above 1.4 bar.

Re: rs6 c5 power loss and supercharging circuit leaks
yes sorry I rectified for the double file,
yes on the log engine until 20/25 min the car had no power

Re: rs6 c5 power loss and supercharging circuit leaks
Something strange going on with your MAF values. They go to zero sometimes, it seems.
Not only that but they go to zero on one bank then the other bank and back. Oscillating. Seems to happen every time.
It looks like something is happening to cause boost to be uneven between the turbos when you lift off the accelerator.
Also the achieved boost remains higher than the specified boost for longer than I would expect.
Most likely culprit is DV valves and/or N249. I would check the MAF wiring, too, but it doesn't feel like an electrical problem.

Re: rs6 c5 power loss and supercharging circuit leaks
I had already surprised the zero on the devices in an alternative way my N249 is original and probably old against my DV are new I will proceed first step N249 and if necessary I will incriminate a DV of bad bill I specify that I have replaced all samco silicone vacuum hoses
Re: rs6 c5 power loss and supercharging circuit leaks
I think you might have several concurrent problems.
What's weird is that the car is only asking for 1.4bar of boost instead of 1.8bar (standard) or more (mapped).
I wonder if there is a problem with your combiner valves or secondary air injection system.
Use the Vagcom to check the misfire counters.

Re: rs6 c5 power loss and supercharging circuit leaks
I'm mapped, when you say combined valves you mention N75, N249, N112? the secondary air injection system could clamp the power? there would be a fault in the Vagcom? the rate counters dint you speak are that of the coils if yes no rates on the 8
ps N249 and N112 origin I think
