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.

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.

Might be missing something here but can that work with an iPad?

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.

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
