Hey guys I got myself a problem lol I got a bf with about 380kw and when It looses traction in second under wot and with traction control off the speedo dies completely until I turn the car off and on again to re set it .. There are no fault codes and its almost as if the car has a boost cut or something along those lines :s the tacho stays on and everything else works as per usual

Has anybody else had these type of problems or similar ?

I had a similar problem with my BF, but it happened mainly at night (with lights on) and the ignition cut out for a split second as well.

It was my Battery, get somone with a good battery tester to check it out, preferably a battery specialist, not just any mechanic

Turns out plugs and fresh coils fixed it
