I bought my imported TT '92 manual car a month ago, and that time has thrown up a few problems.

 

I've just been told that my master brake cylinder has a leak (it does, I can see it).

 

Along with this, after the car warms up, I get what I can only describe as a 'wu-wu-wu-wu-wu-wu' noise from the rear. This rises in pitch with speed until it's continuous and loud.

 

When this stage is reached, if you stop the car and move off again, I get a metallic grinding noise which seems to start under the gear lever and moves backwards.

 

Oh, and after 20 or so miles, the HICAS warning light comes on.

 

My local Nissan dealer isn't much help. Is any of this this connected or is the car shagged in a few different ways? Ant possible causes or pointers would be much appreciated.

 

Ta.

sounds like centre bearing and or universal joints on the propshaft,

 

Any clonking? blurred rear view mirror thru vibes?

 

Hopefully not a worn out diff though or diff bearings. They can make a noise like you describe and drone at speed.

 

If it changes when you turn left or right it could point to a rear wheel bearing instead.

you can change the internals of the brake master cylinder, I think the cost of parts was about £50.

The HICAS light light could be due to either low fluid level or maybe your steering wheel is off central.
