Problems after kleemann install / need help!
I recently had a Kleemann Supercharger installed in my CLS500. Love the new system, and I will be on the dyno soon. Stock dyno resulted in 257rwhp, and I expect 360rwhp, which is good for the CLS500. I want to get her up to 400rwhp with a few other mods.
I now have a short list of problems:
1. No power steering
2. No cruise control
3. No tire pressure monitoring system
4. ABS light is on constantly
5. ESP warning
I was told that the issues were from a bad ECU tune, but the ECU was returned to the stock file, and the problems still existed. I know that my steering control arm was lowered to install headers, so I'm not sure if something went wrong there

I can also feel active power steering after the first 3 to 4 seconds when starting the car, but then it goes away, and gets very very stiff.

Please help with any ideas or recommendations.

I have no idea why this is happening. Thanks guys!
Cory is helping me 100%, and after sending my ecu off to them almost 5 times, we do not think it's the ECU.

Forced to turn to my friends for help.
last option is to send the car to Kleemann, which will cost me more money.

Yes, the car has been sideways recently from a little fooling around, and just getting a feel for the new power, but the issues were already present. Now that you mention the speed sensor, I notice that at high speeds, the steering seems ok, but when I slow down it feels stiff again. I'm taking the car to the shop early Monday morning. I will mention the rotary and acceleration speed sensor to the tech.
after the install, the car would not even start. That was from a wrong file used by Kleemann, who fixed that problem with a new file, which got the car going. I'm not sure if that first file caused damage to the car's system

That situation was not the installers fault. But when the car was started for the first time, these problems were present.
I will pm you the codes Monday morning.

When you get the car to the shop have them look at the electric valve at the steering rack. MB calls it the SPS valve. It's what controls speed sensitive steering. If the connector or wiring got pinched or left unplugged that will set esp, abs, bas, into limp mode. When they lowered the suspension components to install headers could have accidentally gotten damaged. The star diagnosis test print out should give us a better idea of whats going on though.

These are all great suggestions, one of them should nail it down or at least eliminate possibilities.
esp control.
speed sensor.
sps valve.
hard to believe you sent the ecu to KLEEMANN 5 times, your so calm and patient !
I would pay my exwife $100 to chew their legs off. Grown men develop facial twitchs after a phone call from her, lol

Lol! I will keep her in mind.
Changing the ESP control module on Friday.
Speed sensors are good.
Also......power was given to my power steering through a seperate power connection, and it works!!!
Not sure how they did that!
My solenoid was hard wired directly to power, and power steering returned. Also found a fault code saying CAN communication with engine ECU is faulty.
We now think that the ESP control unit is faulty, and it's not broadcasting the wheel speed signal on the CAN BUS. My car is a first generation CLS that uses wheel speed to detect air pressure, so that's probably why my tire pressure monitoring system is not working. This will also explain why my cruise control is not working.
Changing ESP control module on Friday, fingers crossed.
