Common VR6 faults?

Post by panic-mechanic » Wed Jan 09, 2008 2:43 pm

Please constribute if you had owned one. If you had failures as in my list please indicate and others then we expand the list.
I'm going to try and make it VR specific so common to all mk3 issues I'm going to leave or make a separate list here.


list of really common faults I can think of.
1) Thermostat housing cracks/leaks after around 150k km.
2) thermosatat failure.
3) recirculating water pump failure.
4) timing chain Guides wear - drops a valve in some cases
5) breather pipe rots.
6) Abs faults.
7 ) coil pack failure
8 ) HT lead failure - partly due to abuse in not using the correct tool (which should be clipped to your bonnet stand)
9) brake master cylinder failure
10) water pipes/pump failure.
11) maf failure
12) clutch pedal clip?
13) Lambda sensor. I think this will b less common now that we run unleaded. Leaded fuel is known to kill these.
14) throttle body idle motor failure.
15) seems radiator is becoming a problem on the older ones.
16) Serpentine belt tensioner ( Next time buy the one from Goldwagen - it's metal)

That's about the list I can think of.

Mk3 - not only VR specific.
1) heater radiator
2) Window winder issue
3) aircon relay pack under water bottle.
4) Cubby hole handle
5) control arm rubbers.

9) HT lead cable failure (mainly due to been pulled out by cable instead of using correct tool to remove them at the connector).

*Delicate brake master cylinders
*Oxygen sensors (not only VR6)
*MAF goes into early retirement
*Car revs irretically and just dies
*Rubber pulleys that costs a fortune but look like the dogs breakfast after 12 months
*Engine temp sensors
*2nd stage speed radiator fan never kicks in

Yikes - out of your list - only 1 common but it's mainly due to the use of leaded. Should be less now - Oxygen sensor.
Leaky fuel lines - simply age. Not a VR only item.

Most common VR6 fault. Faulty fuel gauge. No matter how many miles on the clock or the age, the fuel gauge has a short in it that causes it to head for the 0 mark at warp speed 19 each and every time full throttle is applied.

clutch slave is simply wear and tear - every car with a hydraulic clutch will have it at some point. Same with heater radiator - mk2/3 common issue - not VR specific. Same with aircon relay switches. Mk3 issue - not VR specific. Actually so is the window winder so I really should pull that from the list.

Mines still top notch but things I've had problems with:
Window winders on all except the driver's
ABS light coming on for no reason. When they checked it for errors there was no ABS error
CV's (obvious reasons)

One new thing I recently started experiencing is when I fill petrol at certain garages she goes fine and then when I want to floor her it's like there's no power. The minute I gently accelerate she goes normally. Could it be something with the petrol at those certain garages or has someone experienced this before?
