CLK 230K
Hi all, im new to the site and to Mercedes, i have a CLK 230K Cabrio which has a strange problem the engine check light keeps coming on, with an error code of P0101 Mass or Volume Air Flow A Circuit Range / Performance.

i checked the MAF and noticed it was a cheapy ebay one, so i have replaced it with a genuine VDO one, however the light still keeps coming back on almost every day with the same code, i have tried the ECU reset procedure and that hasnt made a difference.

hopefully someone will have a few ideas where to go next, i checked all the usual plugs, leads, filters and looked for vacuum leaks etc.

cheers in advance

Would the ECU reset necessarily clear the fault code?
 
Hi

it did when i completed the ecu reset but generally i have been clearing the code with a diagnostic tool, which it doesnt come back on straight away just within 24 hours the lamp is lit again.
