Rumbling noise when driving right but goes away when clutch depressed

(1/2) > >>

Momosan:
Hello new user, I own a mk5 golf 1.9tdi (and a mk2 that's rotting in the garage)

I have had a persistent issue I've been trying to track down for a while but cant find any info.

When I turn right the car makes a rumbling sound, I initially put it down to a bearing so changed that and put a new CV on the passenger side front and then the rear bearing, also changed my gearbox oil. Noise is still there! Then one night by chance I took the car out of gear or depressed the clutch while going right and the noise just disappears?

Anyone dealt with this issue and have any clue?

Car is stock mechanically apart from some 17 inch audi TT wheels

Thanks in advance

I think this would normally indicate the clutch release bearing is on it's way out, no idea about why it would do it when turning right though.

Is it a BKD engine?  I think at a certain model year, some of them had driveshaft extensions on the driver's side to make both sides 'equal length', to help with torque steer.

There's a support bearing bolted to the block which can wear and cause rumbles.

Only mentioning this as a friend's B6 Passat TDI (based on MK5) made a similar vibration/noise turning right, which turned out to be the above.  Not sure if MK5s ever got that mod though.  If you have a long and a short shaft like the GTI, then forget that  :grin:

Momosan:
Thanks for the replies guys, it is a BXE engine, yes I only found out there is a potential issue with these engines after! but when I got it 3 years ago it had only done 65k and was a steal  :smiley:

I will look into both of those, interestingly, I did have a driver side CV boot go bad and didn't catch it until very late? But the noise going when the clutch is depressed eliminates that I guess

Could be the dual mass flywheel if the rumbling goes after pressing the clutch pedal down.  They're wobbly things, even when new, but get progressively worse with mileage and/or driving style.  DMFs hate being laboured (which makes it an odd choice of flywheel for a diesel!) and over-revving, so there's a bit of a operating window to keep them in if they're to last.

Perhaps when turning right, the DMF is tipping over away from the engine slightly, if that makes sense.  I think it might have been an early humble mechanic video, but he showed where a severely worn DMF was actually contacting the gearbox bell housing, which cause a nasty thumping/rumble. 

Anyway, things might not be that bad on yours but worth getting it inspected to outrule/confirm it.
