I've got 2 problems with my m3 Astra GLS. its a 1.6i. basically, whenever I put the car into reverse I get a strong smell a little like burning oil in the cabin. It's a bit worrying as you can imagine, any ideas what it may be?
I'm also getting some wierd readings from my rev counter when in 4th & 5th, it just gives inaccurate readings and waves about a lot.
