Brake Light,vdc,slip Light

[V(35)Powarh!]

Hey guys my 04 v35 coupe is having problems. Everytime I hit the throttle the brake light shows up followed by the slip and VDC off light after a whole the brake light disappears though slip and vdc stay on! It's annoying me and I have done some research, just wanted to know if anyone has had this problem and what was done for it to be fixed...

A few things mentioned were brake pads/brakes mine just hit 40k on the clock which sounds about right when the pads should be worn though my mechanic noted that I could still drive for another 5/10k kms...

Are these lights signs of low brake fluid/pads!? Or is this something else!?

If its the brake fluids should I use dot 3 or 4!? The brake fluid cap on the car states dot 3 only?

Also note the fluid level is half way between max and low so do I need a top off!? Thing is I don't know what the previous owner has used is it alright to mix dot 3 with dot 4!? Or would be best to flush it all first?

Your help and opinions/views would be much appreciated!!

Sounds familiar have you tried the search engine to see if anyone else has had the same problem? Brake fluid is Dot 4, if it's got dot 3 in it i would flush it. I changed all the fluids when i bought my 03 coupe because i was unsure as to what he used.. I would definitely change brake fluid and check everything else while your there.

Your mechanic doesn't know what the problem is?

The first time I just got him to check my brake pads and not the actual fault itself...so yea through searching the common things mentioned were brake fluids/pads wheel balance/sensor etc.... I have done some searching on here but just wanted to see who else had these issues moreso recently..... So dot 4 is the go? The cap of the brake fluid in the engine states dot 3 only though so not sure ay....

I kinda had a similar issue with mine, after I took it to test and tune, heading back home I went to accelerate and same thing, brakes, vdc and slip turned up and the car stalled. Only happened with VDC off. For some reason it just stopped happening, so unfortunately I dont know the issue. I hope you find the issue.

Mate I wish I knew! It could be anything that's the problem and I ain't having fun driving it ATM thinking about what it could be everytime I drive it....

You need to put a scan tool on your car to find out what error code your car is putting out.

Any good mechanic with have one or do it yourself for cheap. It's like having an onboard computer.

Get one of these with an Andriod phone. It will tell you everything about your car as you drive.

Very cool on a tablet.

Very good advice! and it's only $20, i just ordered one myself. Could come in handy

First of all, get rid of the brake fluid and replace it with Dot 5. Give the system a complete flush. If the caps got Dot 3 on it, then I wouldn't trust what's in there.

Scan tool should show the fault.

No2 son had a very similar problem with his Aristo, handbrake warning light, TPS light , cruise cut off etc.

Turned out to be a faulty fluid level sender on the brake master cylinder.

Disconnected the plug and fault cured.

Luckily he had a complete spare master cylinder assembly and all fixed.
