Last week I drove back home on the autobahn. I was going across the highway doing speeds between 210 and 270 kmh, but while doing so I experienced over a period of two days time a total of four limp modes. The car went into limp mode at speeds between 210 and 270.
Today I went to my dealer asking for a read out of the error messages. The dealer needed the car for two hours to do this. I was like uh wait get me a computer and I will do the readout myself. The desk mechanic put the car on a bridge and looked underneath it and said nothing looks wrong...
I was like:
and would you be able to "Get the computer, please". He walked back to his desk and started to write a report asking me to hand over the car for a two hour check with five different points they would need to walk through. I said "Leave it, I am going to a tuner".
Ended up at a local tuner, connected the computer and found the error messages! They said:
Charging pressure control, plausibility pressure too high and
Charging pressure control: Switch-off as consequence.
The charging pressure sensor got a value which is higher than the nominal value and so the car went into limp mode. I can easily reproduce it by doing those top speeds and keep pushing the car.
Any thoughts on this forum what this could be related to? Any input is welcome. I am collecting as much information as possible to get the best possible reply to the dealer so that they know how to fix it.
