Thought I would just start a new thread since it turned into a new topic besides me being excited about finally becoming an owner...I bought from a Chevy dealer and have a short 500 mile warranty. They are fixing the belt squeak I noticed in the morning but they dont want to fix this supercharger problem because its not kicking codes stating they have an old Mercedes Master mechanic onsite who says theirs nothing wrong until a code is tripped and until it does we cant fix it. I will fight if I have to on that point by getting them to do a test drive with me

With that said, I am pretty sure I have the common intercooler pump failure happening on my 2006 CLS55 70K miles. The supercharger seems to be kicking in and out in all transmission modes. Seems to get worse at higher temps. Typical feels like "loss of power" or "loss of 100hp"

I have a couple questions about this issue...

Does it kick out a code/check eng light?
Mine hasnt yet...

Is this because the pump is just insufficient not totally shot and letting the temps get too hot hence the ECU turns off the supercharger until temps drop on there own? Or is it a mechanical failure of the supercharger?

And it wont kick a code until the pump totally fails?

Im thinking if thats the case is there a way to make sure the code is kicked on permanently so I can get it fixed???

Aftermarket pumps seem to be aplenty online and if I am to get some sort of credit to fix it on my own will it be worth it to find a higher yield output pump to prevent this problem?

Are there ones that are plug and play or do they need to be hardwired? I dont want to deal with hardwiring.

I will also say, I am planning on doing a on ECU reprogram soon to increase output once this is fixed.

Any help would be greatly appreciated and sorry for all the noob questions.

 

Ok so update the Chevy dealer took to mercedes dealership and what do ya know, it did have a failing intercooler pump and bad thermostat! So, hopefully I'll get it back tomorrow. They may just throw money at me and I'll get it fixed by my local Mercedes Mech cheaper. Im guessing its ok to drive for a bit till I get it fixed. I wont cause motor damage will I?
