Passat TDI 125kw idle noise.

[mebius9]

I purchased second hand 2008 Passat TDI 125kw couple of weeks ago
I'm a bit annoyed by the noise level at idle

I had 99 V6 camry before this one and it had much quieter idle noise...
I actually measured it

Camry 1999 V6
36~37db

Passat 2008 TDI 125kw
48~50db

and Passat has really boomy exhaust noise at around 1500rpm...

Is this meant to be like this or is somthing wrong with mine?

Its a diesel

Further to the above post the PD engine is a tad on the noisy side as opposed to the new Common rail. Totally normal mate, im sure your wallet will thank you for having it compared to the camry

Well, rest of the car is just not comparable I mean... wow the interior, handling and design... Passat makes Camry interior look like 100kg of molten grey plastic.

I'm just suprised that 11 years old Camry actually has some high points against VW Passat!

A similar injection diesel Camry( if one existed ) would be just as noisy. It's due to compression ignition and super high injection pressures giving your generally much less powerful diesel engine similar performance to a V6 camry. If you wanted quiet idle, you should have gone the petrol version. Also, you shold be avoiding less than 1800rpm, where the engine is "off" boost, and thus producing a lot of DPF - exhaust particulate filter - clogging soot in the exhaust. Leave the DSG to do it's thing, or keep the thing around 2000rpm and above. I often drive in 3rd at 50 - 60kph in my similarly engined GT TDI for that very reason. You'll get better fuel economy too.

Ah ha, so that's why car seemed "Happy" at 110kph... it was sitting at 2000rpm and felt way better...
still getting to know the car.

As Greg R said, don't be afraid to give it some stick, the diesels love it ♥ and unlike the V6 Camry you had (given the same treatment) you won't be back at the servo refueling after an hour or so either. I also have a Golf GT TDI (125kw) and and even with a damn good fanging every now and then I'm still getting nearly 900 K's to the tank and I never let the fuel level get too low. Over 1000 k's a tank on a trip would be easily obtainable. Congrats on the purchase by the way and hope you enjoy it :>)

Thank you
Yeah it's funny how it likes to rev being a diesel and all and it's actually smoother above 2000rpm.
It's got a nice shove after the turbo spools up weeeeee~
