Guy,
My beloved 2009 R36 seems to has developed a bit of issue lately. I've been getting a lot of wheel spin at the low gears when I push the car a little bit hard. I did just have had a major services done but the problem seems to have occurred just before it and I dont think some new spark plugs would have make the car produced heaps of more power! Also the types although is not new but in reasonable condition as well. The only other thing I have got done to the car is had a Front brake rotor and pad replaced with a aftermarket slotted disc, which seems to be working fine if not better.

From some research, I have seen ppl suggest that it could be a Halex AWD problem which turn car into a more FWD rather than AWD but I have not notice any warning lights on the dash.

Any suggestion is welcome and appreciated!
