Engine Management Light

[190E 2.6]

Hi

Please help

The engine management light came on on my C32.
Took it in to Merc and £700 pounds later and a week after the light is back on.

Apparently they had to fit a new Secondary Air Pump!!

Now the light is back on and I am not happy.

Taking it back to them tomorrow.

It may need a Air pump switch over valve as this is a common fault, only about £20 to buy
