Hi All
Could someone give me more info on BMW dealership services for tuned cars..
I have had Hartge tune installed on F20 118i.
So the unit is plugged into some different engine sensor plugs right.. (air pressure, turbo pressure and what what)
And apparently the tune cannot be picked up by normal service software checks*
So the question...when having the car serviced, do they plug anything into these sensor plugs or do they only work from/through OBD input?
otherwise it means i would need to unplug/remove tune box before service every time? as not to lose motorplan/warranty etc
Any info would be appreciated

This is directly from Hartge
The Hartge Engine Conversion is significantly different to other, often cheaper systems.
Our Hi-Tech system contains many "smart" technical features,
and is the result of many months of design, testing
and durability trials.
The investment we have made during the development program has resulted in a full 3 year warranty
on the hardware and software, plus an insurance backed engine and drive line warranty,
covering any effect of the increased power output for a period of 12 months
from installation date, but limited to 6,000 Euro.
Technical features are as follows:
The Hartge ECU is an external additional control unit. It is internally sealed and cannot be detected by BMW service
procedure interrogations.
It is also not possible that BMW software updates can disturb the performance of the Hartge ECU. Unlike engine
management "chipping" and "flash" upgrades, it never gets overwritten during service enhancements by BMW.
The Hartge ECU is connected via a special wiring harness to the rail pressure sensor, control valve turbo charger,
boost pressure sensor 1, boost pressure sensor 2, air flow meter, water temperature sensor,
camshaft sensor (all plug and play) and power supplies.
Additional power is generated by increasing the turbo boost preassure by a precisely calculated number.
This number depending on engine speed, calcualteed engine load and other parameters.
The BMW ECU continues to monitor all other important engine parameters as standard.
Therefore the engine behaves as standard to ensure that the standard emissions controls remain intact for the standard
emissions tests and drive cycle testing.
There is also overload protection, which prevents full power from being delivered for excessively long periods of time,
for example when towing heavy loads, or driving for too long at
V-max. The Hartge ECU also prevents overload of the transmission at lower than 1,200 rpm,
and overstressing the engine at high power outputs.
In extreme temperature conditions, the Hartge ECU also monitors the exhaust gas temperature,
and if this exceeds the safe limit, the Hartge ECU reduces power accordingly back to standard BMW power.
All standard BMW engine protection and emissions systems remain in place and continue to function.
