Noisy 2004 E320 Cdi.......Noisy??

[shaunevans1409]

Now then.....

Read recent posts about a noisy S 320 CDi, and I reckon mine's a bit on the clattery side too. I've had 6 new glow plugs fitted recently, so all's ok there. The engine seems to warm up in a reasonable amount of time too.

It's quieter for sure when it's warm, but noisier than i would expect, quite buzzy in the cabin until the speed builds up. The clincher was I stood next to an E class at a junction today, when it pulled away it was nice & quiet. I was amazed - E320 Cdi on the boot!

A few things to bear in mind......

The car was serviced about 2000 miles ago.

Milage 72000.

Could it be the Tesco brew that i'm filling her up with?

And....This is the first diesel I've owned (although not driven).

I'm perhaps being a tad critical, but your thoughts/opinions are welcomed.

I'm going to the meet up at Duxford in May so will see what you all think then.

Cheers.............Shaun.

You have to remember that all derv engines are noisy, the CID3 that you have, injects 3 times on it stroke until it warms up, hence you get derv knock or as the old timers call it over fuelling, if you want a quiet engine then you buy a petrol lump. its getting better now with the 642 engine with the new crystal injectors, much better!
