I'm not after going faster than the 155mph my car is supposed to be limited to, more trying to understand a possible fault. How does the speed limiter work on a C43 AMG, what tells the ECU to stop whatever would make the car exceed 155mph?
Giving it some beans the other day, in the safest of manners of course, the car just refused to go faster than a lot of tens of mph less than 155mph. it got to where it decided was today's limit quickly enough, just no more.
On my list of jobs anyway, is fuel filter change, compression test and coil/lead spark voltage test (all plugs replaced a short while ago - as was the MAF). Don't think it's compression, as no other symptom for that and no gradual reduction in the 'limit'. Is there a possible ECU issue or some sensor somewhere?
Thanks..
