1) Voltage supply to electrical components. 2) Safeguarding circuit of electrical components. 3) limiting overvoltages. It certainly is possible that it could be causing your concern, maybe you could ask your mechanic to swap the one from there company c280 for trial? |

Thank you for you post Ozz,
It seems that the replacement of the OVP relay did not solve the problem at all. It happened again after the 2nd Day of the replacement. At the moment, the dealer is ordering a new wiring harness from the factory in Germany as they say this is the last option. I hope this CAN Bus wiring harness should do the trick; i was informed by the dealer that they are having similar complaints like mine in some countries in Asia too. Going nuts by now! |

OZZY or Anyone............

Man, I thought it was fixed for good.
An indie mechanic replaced the ovp relay on 22nd January 2005 and concluded that it would fix the problem but the d@mn thing happened again on 10th February 2005. Does a failing alternator affect the IFZ transfer to the HFM? I have an equipment (ref to the pic; have you seen this before?) to test the charging on the alternator. It seems that the alternator is not charging well because whenever I tried to switch on all electrical equipment (air con, lights, stereo etc) in my car. Going nuts by now too! Appreciate your comments. |

I have the SAME PROBLEM!
Hey guys, holy moly, I have the same Problem!!!! I have a 94 C220. My car's been doing the same funny stuff as "thegirlilove" has been. It first started 2 years ago, once every month or two my car's engine would turn, everything would be normal, except it wouldn't start. During this time, I have changed, my fuel pump, engine wire harness, done an early complete tune up, changed the car's battery and many other smaller repairs. However, my problem kept getting worse, and started to happen more and more often. It reached the point 6 months ago where it would do it a couple times a week. Each time the car's fine, it won't start, so if you go for a nice long walk, come back and it would fire up just fine. However in the last 2 months it has gotton real bad. It does it every third time I start my car. Its embarassing, you go shopping, come out, someones waiting to park in your spot and you sit there for 10-15 minutes to start your car, and slowly your lights start to dim from all the power you've used attemting a bunch of starts. I was still fine using my beloved benz with this condition. I've taken it to my mechanic many times, and they put it on the computer, and tell me it comes out clean, with no errors, and can't seem to figure out what's wrong. I've spent $4500 dollars trying to fix the problem and it keeps getting worse.
Currently this problem has reached an all time bad, so bad that my wife won't even touch it, and calls it a peice of sh%t every morning when she see's it. Now when your driving the car, say on the freeway going 120 Km/h or in town at 80km/h, it stalls on you, and your journey comes to an end. So when your stuck on the road, the car won't restart, you'll sit there for 5-10 minutes if your lucky, and sometimes 30-60 minutes, for it to restart. On top of that, my car has recently burned out a relay which I can't seem to find. Sometimes, my turn signals, emergancy lights, misfunctiong wipers, and rear defrost all stop working, or working in spurts. The last 15 times, my car has stalled on me, and refused to start, half the times, i havn't been able to put my emergancy lights on and I sit there on the road, and people have almost managed to smoke my car, and find away to cut through the freeway pushing the car in netural to the shoulder. I nolonger am able to safely use my mercedes. When I bought my Car, North Vancouver Mercedes in Canada, sales man, "LOREN FREEMAN" told me, my Mercedes was engineered to be the best car in the world, and not only that, Mercedes car's were designed to be the safest. Right now, I nolonger feel like any mercedes dealership should tell their customers that, my car is no longer safe to drive, let alone be in. So if any of you guys can help me, I would be very thankful. I know when I ever have money again, which this benz hasn't let me save up, I will have a hard time convincing my wife to buy another as a family car. The problem with mercedes is, they have taken some simple idea's and made them overly sophisticated for practical use. A moter can work for 15-20 years, but if you allow a computer to control it, that computers life span is usually 10 years max. With the new line up of mercedes, if you buy one, I hope you pray everyday once its 10 years old. |

engine wire harness
The engine wire harness is very expensive, and they will charge you an arm and a leg for labor also. I was charged 8 hours diaognostic time, since it took them 2 days to figure out my problem, which they said was a engine wireharness falling apart. They ripped it out, showed me, and I was like, fine, its goning to cost me a fortune, but do it. The problem was never solved. I guess the brittle looking engine wire harness was still fine.
I use to have a sound system in my car, which I only kept in it for 4-5 months. Mechanic said, it might be sucking too much power, and causing the occasional problem. I took it out, and it never made a difference, and changed the battery.....i had a rockford fosgate amp (225.2), 2 - 12'' Rockford fosgate subs, 1 - 12'' phoenix gold sub, and two 10'' Pioneer subs, all of them in there at once, my whole trunk was occupied. Took it out, everythings sitting in the garage. But car's still working like crap. |

The MB Dealer here charged me for new keys, car battery & IFZ COntrol module and there were no refund AT ALL! A question for OZZY Is the crankshaft position sensor located anywhere near the handbrake of a 1995 W202 C280? |

So i was just wondering if these guys did do something to the any areas or in the CAN area that could have led to affect my handbrake being loose as well as leading to a sensitive part of the ECU/HFM's connection? I would appreciate if you could furnish any HFM related modules/ parts that are located near or around the handbrake area? Thanking you in advance Last edited by thegirlilove; 02-15-2005 at 05:08 AM. |
