G60 Bob 0 Posted June 26, 2006 G60 was running lumpy and smelt of black gold (petrol) so i swapped the blue and black plugs of the temperature sensors and 'hey presto' the car ran perfect but the water temp didnt work - diagnosis replace BTS Two days later before i could replace BTS started running lumpy again and was hard to start smelt of petrol again. I have replacd the BTS (from VAG) four times now in two years of owning the car - could it be a short circuit, break in the wiring or something else causing the BTS to fail (nothing obvious in the accessable wiring).

Henny 0 Posted June 26, 2006 what coolant are you running, and is it nice and clear or full of rust deposits? Rusty coolant will kill the BTS pretty quickly as it builds up on the aluminum sensor and stops it from reading properly... Quote Share this post Link to post Share on other sites
G60 Bob 0 Posted June 26, 2006 Its filled with 2 month old G12+ so i dont think that could be it. What made me think it is somthing other than the sensor itself killing it is the fact that i swapped blue and black electrical plugs over and the black sensor that was then being read by the ecu died. Any ideas? R Quote Share this post Link to post Share on other sites
Henny 0 Posted June 27, 2006 get it to an auto-electrician and get them to check it... Sounds like you've got something funny going on with your wiring which is putting too much voltage down through the sensors... :| Quote Share this post Link to post Share on other sites
G60 Bob 0 Posted June 27, 2006 Replaced the blue and black sensors together yesterday so we will see how long they last. Cheers R Quote Share this post Link to post Share on other sites
