Hi
I have a 2003 Golf 1.9 TDI (150HP, I think) UK model.
It has done 140,000 miles and still is still going strong with lots of acceleration and it gets about 500-550 miles on a tank (c.46-48MPG?).
My one complaint is that it is too darned noisy! I dont suppose that there is much that can be done about it but there is a certain amount of wind noise & tyre noise (esp on the motorways - depending on road surface)... but my MAIN complaint is just how noisy the engine is when under load!
So I would love to hear any suggestions as to what can be done to quieten the darned thing (for inside the car).
My preliminary thoughts so far:
1. Put extra/different/more rubber padding under the bonnet
2. Put layer of heavy rubberised felt over the carpet everywhere possible
3. Paint a layer of thick rubber solution
a) behind the engine
b) under the car
4. Change the exhaust pipe (but to what?)
5. Clamp some sort of vibration absorbers onto the engine mounts to lessen the vibrations getting into the chassis
6. Put the lid thing back into the boot area (if I can find one!)
7. Use some Mk 6 Golf parts (??)
I understand the the NEW Golfs (i.e. Mark6) are VERY much quieter. I just wonder how VW have achieved this - anyone know? Are there any Mk6 parts that one could use?
Any other thoughts?

Welcome to the forum :smiley:
At that age I would have thought engine mounts etc would be past their best so look at replacing those, especially the gearbox to subframe mount as this will reduce engine movement
Is your engine undertray still fitted; most have been ripped off by now
Tyres play a big factor in road noise so make sure you don't have cheap and nasty stuff fitted
MK4 and MK6 are 15 years apart in terms of design and technology so unlikely you'll find anything that will fit.
Cheapest option by far is to buy some earplugs :grin: :grin:

Worth a thought - thanks.
> Is your engine undertray still fitted; most have been ripped off by now
Yes - although it keeps dangling rather low and catching the road given half a chance...
Is it worth finding a thicker/better more sound-absorbing tray?

No, I have expensive ones.

But not helpful when trying to make phone calls (via headset of course) :^/

The under tray is already the thicker model so perhaps replacing it would be a good option. They are not cheap though! Around £100 just for the main cover. The side covers are then approx £30 per side

Gave mine a full service and that made it less bus like.
Also sounds weird but just fitted my milltek decat and that has made such a difference to the sound of the engine.
Dont know if you found that Rhyso?

Just had a full service.
Forgive the newbie question but a "milltek decat" is that an exhaust system from http://www.millteksport.com/?
(If so, how come they dont list Golf under VW, under Products?)
Roughly what did it cost & what difference to the performance did it make?
a) power
b) MPG
c) Engine noise

Can't remember if I'm honest; I do remember giggling because it hooted like an owl off throttle :laugh: :laugh:
Decat is best when the car is remapped as it will help add a couple of bhp and lbs ft torque. On its own its unlikely you will see any benefit

I ahve a 1000w twin sub in my boot, tends to drown out most noises :grin:
-
Hmmm ive done an 18mile 50mph drive up a motorway behind a tanker and achieved 80.1mpg wheres before it was 69.1mpg :)
Decat and panel filter are the only things that have been changed since.

You will have had less drag due to slipstream so would have used less fuel :cool:

6. Put the lid thing back into the boot area (if I can find one!)
if you mean the parcel shelf then def get one as it cuts a lot of noise coming of the rear section of the car as at mo i have mine off as stripping interior lol again and on motorway noise level a lot higher than with one, cheapo fix m8 srappies
