Hi all,
My 2004 E200k has developed a judder/thump and hesitant to accelerate in the lower revs. This is much prominent in the mornings when cold. Seems to be ok when it reaches normal temp.
The gear changes are smooth - etc. Also the car has started doing really bad on Fuel - i'm averaging 20mpg when on the same route/drive it usually does close to 30.
I did check it on STAR and there was a stored code of Exhaust Solenoid - I believe Y49/3. Apart from that all seemed normal.
Could it be the dreaded Glycol issue? How do I check what make my radiator is?
MAF going?
Please help.
Usman

Have the garage do a gycol test on the gearbox oil.

Valeo rads were present in some 2004 211 E classes.
