Hi All, I am a newby to the MB Club and only joined about 2 months ago after buying my first MERC(C180 Kompressor SPORT 2006) 3 months ago. I was very happy after owning a people carrier for a few years, the MERC was heaven. About 3 weeks ago the same happened to my beloved MERC, engine management light came on. Took it to my local garage that I have used for years. Diagnostic was done and showed 3 or 4 codes . I have since replaced plugs, spark plug seals, coil packs and numerous diagnostics, and £300 later, light still on.Local garage were stumped. I decided to contact the steelership directly ,hoping for some help as the final code had something to do with "fuel emissions or fuel mixture to rich". They wanted to charge me another £95 for diagnostic before any advise or help. I read all the replies and decided to purchase a can of "ecotek power boost" to try as a last resort. Rather spend £24 than £95 for the steelership. I decide to start with the basics, drove car until empty and add £30 of SHELL V-POWER petrol. I went to purchase the Power boost today, as step two of the basic's, clean out the engine. It was about a 50 mile round trip(gave it a bit of a welly) to the spare shop to collect the Power boost. On the way home, wife wanted to stop for some last minute shopping. Got back to the car, and lone behold !!! ENGINE management light has gone out !
This should be a lesson to me not to use supermarket petrol(ASDA) and stick to the good stuff! I am still going to do the Power Boost tomorrow as I have read some good stuff about the product. I know this might most possible not resolve all the issues for every one, but I wanted to share this as it has opened my eyes and possibly stopped me from wasting any more cash.Hopefully could help others with the same problem as it could be as simple as using the correct fuel. Very happy MERC owner again !!!!
