my 2000 c230 kompressor acting strange

I have a 2000 c230 kompressor with 144,000km. I acclerating on to the highway and as I pressed the gas pedal down the engine lost alot of power?? It felt as though the more I pressed on the gas pedal, the more the engine bogged. It has never done this . It feels like the supercharger was not engaging?? I am overdue 25,000km for a B service. It was ruuning fine just before this. I will be taking in tomarrow to the shop. any idea what this may be?? Is the super cahrger starting to fail? or???

Do you have a check engine light?

If YES, read the OBDII codes and post on here.

We will then be better placed to make an informed decision.

Thanks for responding FAR888. There is no check engine light on. I stared the car this morning and it is running fine as it usualy does. I checked the oil and it is full and clean. I am still going to take it to the local shop. There is a German man who owns his shop and has been working on these benzes for the past 20 years. I really value that I can speak directly to him about my car. He is the only person who does the maintenance on the german cars. He also has a shop rate of $ 70/hr . The local mercedes benz dealer charges $120/hr . I will keep ypu posted.

Thanks.

Brad.

I had a similar issue once trying to pass someone while going up a hill, my car didnt respond as I kept giving it more gas but after a few seconds it finally zipped ahead... was a bit disturbing but I've never been able to make it struggle like that again and no codes

this has happened to me before. when ever i gun it and the rpm rise above 4500 or so, the kompressor will disengage. but once i turn the ingnition off and restart the car it reset the clutch or something.

i have found that my kompressor engages at 2100 rpm and will cut out from time to time at 4500 rpm or more. it's does this more often on hot days than cool days.

can anyone confirm the time at whicht he kompressor will engage.

being at 2000 rpm it makes for a great 20 punch in 2nd gear.

I read once it engages at 2000, but I do agree with you that it is slightly above 2000

Fixed this problem recently. It started about 6 months ago with power loss on quick accelaration. In a few weeks the check engine light came on. I had the codes verified and got P0300, P0302, P0303, P0304 (misfire on various cylinders), P1747 (CAN Bus fault), P0170 (Self Adaptation at limit). They wanted 3 hours of repair time to diagnose the problem. I din't do it. Then I took it to AAMCO they check codes for free in CA. The said the problem was with the transmission and said Trans rebuild would be a minimum of $5000.

Meanwhile, reading the forums here I found that the MAF was the most common reason for this problem and sometimes the O2 sensor. The problem was code P0170, which will cause all other codes to popup.

Inexpensive solution to this problem:
Check out MAF cleaning proceedure in this forum, this will take about 15 minutes for someone with no prior experience.
1. Find MAF its located in the area marked in red in the first picture.
2. It's very easy to remove. Need a flat head screw driver to loosen clamp.
3. The second picture shows what it looks like. It is inline with a 2" hose near the air intake.
4. make sure you specifically use MAF cleaner fluid ($3.50 for a can at autozone). Douze it generously and wait for it to dry (5 min).
5. This will improve performance, but if the problem does not go away you may have to replace the MAF, make sure you buy a genuine Bosch part not from kragen/pepboys etc.

Let me know if you need more pictures or details.
