I have changed nothing since I last drove it, and it almost feels like its traction control kicking in, or the TCS or something.So I tried enabling/disabling traction control again, and also the TCS and it still does the same.Is this an indication that something physical is on the way out, or is it my electronics playing up?CheersMike :( Link to comment Share on other sites More sharing options...

Was pretty warm today. You might have just been down a bit on power, which meant you didnt have enough power to keep 2nd gear going.The BF's with ZF tran's do all sorts of wierd things if they got hot and they think your trying to hurt themLuke Link to comment Share on other sites More sharing options...

Does it feel like your losing power or is it something else?Perhaps the diff bouncing its helping the rear end squat and grip up, but then you think about it, when it bounces back up the wheels would start spinning like a b#stard again?

I dunno I've never had any problems ever hitting second gear at full boost and the rear not spinning. And yeah good luck explaining that to the service dept! hah that's why I thought I'd ask here straight away!

Be careful you can snap an axle. Arron Link to comment Share on other sites More sharing options...

I didn't try it with Traction Control turned on.. otherwise it wouldn't have even let me spin up first gear. Sorry for the confusion, too much sun at Motorvation today.

Tried it this morning with no aircon plus a cool morning, and BINGO problem gone.I never knew the aircon sucks out that much power, its terrible!
