The engine management light came on the other night on my C270 , along with the usual drop into 'limp mode' .
After restarting 3 or 4 times it would reset and drive normally for a short distance before the fault would come on again .
I felt the most likely culprit was the MAF , but not being 100% sure , I opted for the cheaper alternative one from ECP . After fitting this last night , I was able to clear the fault and the car drove several miles before the fault came on again .
It may be that the cheaper MAF is not a suitable replacement , or it may be there is something else wrong ( I will check for leaks on the induction side over the weekend ) , but in any case some means of diagnosis would be beneficial .
While I could go along and pay someone to plug the car into Star and tell me what is wrong , I'm thinking that there are lots of DIY EOBD diagnostic tools out there , available at a modest cost , which would also work on the various other cars in the family besides my C270 ( my older cars wouldn't benefit ) . While I would not expect the same level of detail or functionality as a Star machine gives ( it would not be reasonable to expect the same of a generic £100 tool as from a dedicated tool costing several thousands ) I would hope that it might be sufficient to point me in the right direction for DIY repairs .
Has anyone on here used any of the generic EOBD fault readers ( such as Gunson , Laser , Sealy etc ) on Mercedes cars , and how much use did they find them ?
