[TearsInHeaven]

Good evening,

I am reaching out to someone who understands this better than i do in order to help me with this very unfortunate situation.

I apologize in advance for the long read, i will try to explain what exactly has happened to my car. I ordered the RaceChip RS for the BMW 3 Series (E90) 335d 2009 and it imeddiatlely after installation damaged my vehicle... My car was running perfectly fine before the installation of the RaceChip RS. After the installation my car would not start. I spoke to the technical department at racechip several times and they are well aware of what has happened to my car. They told me to install the deactivation chip so that's what I did. At this point my car started but was running uneven on idle and the check engine light was turned on. A warning for increased emissions showed up on the infotainment system. So I contacted the technical support once again, they then told me to return my car to the stock tune and take it for a test drive. They said that doing this would make the fault codes disappear and my car would run normally again. I listened to the technician and restored the car to its stock state. However the problem persisted. The car was still running terribly uneven and the check engine light was turned on (this also resulted in a massive power reduction). Once again I contacted the technician at RaceChip, he then told me to go to my local car workshop and remove the fault codes on the ECU. I took my car to the workshop. The workshop printed the fault codes and removed them. The fault codes would not disappear and immediately lit up once again after the deletion. At this point the car is behaving the same way it was before the deletion of the fault codes. (uneven idle and check engine light illuminated). I contacted RaceChip for the 15th time. The employee on the phone said he cannot help me and that i have to send an email.

My current situation is as follows. I have a car that is not running properly due to the RaceChip RS. (that is not installed but only damaged my vehicle). I find RaceChip responsible for the damage caused to my vehicle.

I emailed RaceChip and got the following reply:

"RaceChip is an additional control unit which means that it can only move within the engine's and transmission's tolerances. The ECU, as well as any other control units of the vehicle, is permanently checking all its security system's values and monitors it's limits in order to prevent the engine from overload and damages.

The RaceChip is working with the characteristic curve of different sensors and does therefore not impact the security systems of the ECU at all.RaceChip is physically not able to cause such damage to the engine. Furthermore each sensor has a over voltage protection which means that if a value is too high for the sensor to be processed the sensor just switches itself off in order to prevent such a damage from even happening."

Can someone explain to me what couldve happened to my car and why its behaving this way.
It's currently in the workshop and they said it will cost about 1000 Euro to repair.

Thank you guys in advance!
