What makes that whine on the cold start? as mine does the same?

Supercharger?

Supercharger?

I thought that but i've been told they don't engage till 1,850rpm

Correct the 'charger doesn't spin until 1850rpm, unless the ambient temp is 5c or lower when it will spin at start-up to dispell condensation within the 'charger.

I was told that start-up whine was the muti-geared oil pump. Mine made the same noise, as has every 55K I've heard start-up. Never been a problem, very characteristic of the engine

Oh thats cool then lol, Thanks whitememesis

Yes, I think it was B1g1an on here who solved the mystery (at least for me anyway) - it's the oil pump.

I remember when mine was started in the show room before I bought it and I thought, "oh god, sounds like it is knackered already" but then I just assumed it was the supercharger (but knew it would be inspected by my inde so wasn't worried).

Ha! Exactly my experience on purchasing my CLS55

I think all m113 variants do it. My old clk55 did. I think my current clk500 does too but I don't drive it often enough to remember to be honest lol. Will check tomorrow.

Sounds pretty normal like a E55 should.

 

[b1g1an]

Yep, oil pump, thanks for the nod JohnEBoy

I had this, opened the bonnet and realised I'd locked the misses in there. A hazardous removal procedure.
