Hi All,
I am new to the forum. Hoping some of your experties may help me identify my issue.
I have a 2004 C270 CDI. My engine management light (eml) came on a few days ago. I took it down to my local Benz specialist (not MB) and he ran a diagnostic on the the car; diagnostic showed no faults, and the mechanic said it was due to the fact that I was driving the car on low diesel with fuel light on... something about a misfire whilst low on diesel? He turned the light off and said it should be fine.
The light came back on the next time I started the car, but with no fault codes appearing I am at a loss and not sure what to do. I am sure if I take it back they can have a look around, make suggestions and change parts but without an obvious fault that could take my garage bill through the roof without resolving the problem.
I have noticed on occasions that the car is making a wheezing noise when I accelerate, when it does this the car feels abit groggy, but this happens every other day and rest of days it sounds fine.
Also I have found that when I put the heating on or the air con on it takes a long time to do both jobs doesnt heat up quick, and doesnt cool quick; also on a couple of occasions when I have put the windscreen heater or the fan on it would be running fine and then suddenly makes a choking noise (kinda like a hoover when you get something big stuck in it) upon which I would quickly turn the air off, when I switch it back on it starts to run fine again.
Somebody suggested it might be an airflow problem, possibly blocked airpipes or something. Has anybody had any similar experiences or know what the problem might be. As mentioned above no fault codes appeared on dianostic machine and the only obvious issue seems to wheezing noise on accelaration.
Thank you in advance for your help. PS as I am new to the forum I dont know if I should be creating new threads? apologies if I have got it wrong.
