Hi people,

having a E220, 194 HP modified to 225 HP and 507 NM.

I am getting the following issue after doing full throttle at high speeds. For example, I get faster to 230 kmh as before but after I reach a higher speed I lose all the power and need to stop and start again the engine and everythings is back to normal. Even if I got between 100 and 180 full throttle after several minutes I get the same power loss.

While reading ECU I get these errors. The company which tuned it suggest it is the EGT sensor that reads too high exhaust temperatures.

Any ideas to help?

P008A09 The pressure in the fuel low pressure circuit is too STORED low.There is a component fault.

P2080FA Temperature sensor 1 ''Exhaust system'' (cylinder STORED bank 1) has a malfunction

Hi there, first i think is to read the car with proper software, like Xentry. I don't know what kind of diagnostic is this, but i think this is not a Star Diagnosis.
Secondary, what they tuned? Only re-remap of fuel chart or they made hardware upgrades?
And at least i don't think that newer cars are allowed to be tuned much more, because of ECO bull****s etc. So that's why MB eliminated this option.

I deleted the errors. The EGT Sensor error keeps coming up. I will go back to REMAP company and they will check again all the tunes and the EGT sensor data. I will come back with new info. Thanks!!

I have a tune on my e200 (petrol) and with those warnings I would choose to remove the map, atleast to see if the issues go away.

Hi guys. I’m facing the same issue on my w213 194hp E220 4Matic. No error, nothing. Need to stop engine and restart for this to go away.
Anyone with a suggestion please?
