How to do W220 ESP Variant Coding Correctly with Xentry Mercedes MB Star C4
Go to the ESP module under
CONTROL UNITS
CHASSIS
ESP
Fault Codes
Select C1511-005
1.to the right it should say CURRENT or STORED
hit F8
It should show you how many time the car has ben started after the code was detected. "0" means the fault is CURRENT, any number greater than 0 the fault should be STORED and past history. The ( obviously ) higher the number of start cycles the longer ago it was.
(If it was a long ago and a stored code, I would clear it and move on. If it is current, you can force a variant locking reset of the ESP module in Xentry Mercedes and see if the code returns. If the trouble code returns, that would make it a current and ongoing error. If that turns out to be the case then perhaps the ESP module has gone "breasts skyward"
2.Double click C1511-005
Read the pre conditions
hit F3
read the sequence and follow it to (hopefully) force a variant coding re-read/write.
t would seem that the ESP reads the ECU on every start up. Having a bad TCU MAY be contributing to the ECU variant coding being off kilter. I would think there would be some P2000-P2564 series codes displayed for that though.
I have no training as a Xentry Mercedes mech/tech and offer this as just a possible direction to proceed in. The ( very ) highly paid professionals at the Dollarship or the ( not so ) highly paid folks at a good independent shop should/would have the final say
