Kick Up The Rs 0 Posted June 21, 2006 Whilst investigating an 'orrible burning smell coming from the exhaust manifold area of my G60, I noticed that the 4 wire connector mounted on the rear engine mount has two of its wires broken off! Can anyone tell me what this connector is for? - car seems fine & dandy besides the burning smell! Whilst on the subject of burning, there is a sign of cam cover gasket weeping at the rear, but the smell has only startedd since fitting a smaller pulley, yet the smell is definately coming from beneath the inlet manifold and not from the pulley area. Is it possible that there is a higher exhaust temp now due the smaller pulley being fitted which has made the smell more prominent? I'll get this bloody car right one day...

Kick Up The Rs 0 Posted June 22, 2006 Bloody hell! I'm amazed that the car runs so well considering I aint got any closed loop control! Have noticed the cat smelling a bit 'eggy' recently, but I put that down to the more aggresive fuelling of the G-Werks / SNS chip! I wonder if I caught the connector whilst fitting the new pulley belt??? Do you reckon the burning smell could be due to the cat getting a lot hotter than normal it's not being fed the right mixture of burnt gasses due to the lack of closed loop control?
