SLK32 AMG intercooler pump

[mjoshyuk]

I am just replaced my SLK230K with a SLK32 AMG (2002). I knew when I bought it when you put your foot down the supercharger disengages.

I was going to try replacing the fuse before buying a new intercooler pump. What size fuse do I need and which one do I replace in fuse box

its not the fuse, check the pump is a runner, even if it is it may not be 100% so probably requires a new pump, very common issue on the supercharged cars.

+1 doubt its the fuse, most probably the pump is goosed very common as mentioned.

Mine went recently with the normal lack of power after a few little runs. New CM30 pump and its all sorted.

I would be inclined to fit the uprated Johnson pump. I have one left in stock at £175. Its cheaper than the MB one IIRC.

Not 100% on the SLK but the C32's it is fuse 5 on the rear SAM, there is also a relay which from memory is in slot C its adjacent to fuse 5. I can check on WIS though to confirm.

My mistake on the SLK32 its fuse 23 front SAM and relay is K3.

Hi

Is this the same or better than the AVT bosch intercooler pump I keep reading about

I've never seen a Johnson pump fail. I've seen a Bosch one fail though.

UPDATE

I went to my MB dealer and they gave me a 7.5amp fuse, changed it over with 5amp this morning and its fixed. 100 miles and £40 petrol, all is well

Thanks all for your help
