Excessive Wheelspin on takeoff in the wet..

[OilBurna]

Guys and Gals,

have a TDi wagon (103kw version) seems that if I want to takeoff reasonably quickly I get excessive wheelspin and axle tramp in the wet before the traction control cuts in, ie for what seems like 1 / 2 seconds. Is this anything to do with the electronic differential lock. Anyone other TDi owners had the same experience??

In the wife's Merc (also FWD) the traction control seems to cut in a lot quicker and no axle tramp, it has a lot less power and torque though. Is it a case of the diesel torque overwhelming the electronics before the brain kicks in?

tyres are still pretty much brand new - Dunlop SP Sports.

I got one of these:

It fixed the axle tramp feel and is easy to install.

My 103kW sedan does exactly the same. I even have the wider 18" tyres as part of the sport suspension package and it still does it... The traction control seems pretty crude at best.

My work car (Mitzi 380) doesnt seem as bad and it puts down 170kW through the front wheels

I reckon the tires may have a part in the wheel spin. The first day I took delivery of my R36, I took it around a corner at speed (not excessive and have done so in other less capable cars which performed better) it understeer quite significantly. My conclusion is the tires. The dunlops. I definitely wont be replacing the same ones.

The understeering just felt like the tires werent gripping to the ground as they should. I have only ever experienced such understeering on wet roads and the road was not wet.

Does the Passat have a W button? Using it on my GT TDI makes a big difference in the wet.

thanks guys suspect that may be part of the problem along with the EDL and the traction control...

the axle tramp is due to sloppy engine mounts designed to increase comfort and decrease fibration.

fibration hehehehhehe?

the merc doesn't do it... once again prob has about half the torque.

From memory , the W button stands for Winter, and starts the car in 3rd gear to avoid wheel slip in wet/icy/snowing conditions.

lol you wouldnt be able to start the car in 3rd gear without destroying your clutch(es). it just restricts the torque so you accelerate slower.
