    Hi all, So I ran into this problem, I left my car sitting for close to 2 days, and it completely drained the battery. I used a multimeter and found that there was a 7Ah draw when car is off/everything turned off. I was able to stop the draw by pulling the glove box light fuse. Now the problem...

    Hi, I'm new here and hoping someone might direct me to an obvious link... I have a 2005 525i M Sport Tourer - think it's not a regular model (a water pump cost £1000 as it was unique to the engine!). I heard some "S" models are specialist build? The battery has been draining with the error...

    Hey guys, I put catch can a month ago on the M4. When I checked today was quit surprised how much condensation and oil got caught.

    Hi, I have a e46 coupe 330i fl with harmon kardon system preinstalled.

    Went to do a coolant flush today on my e39 525d. Raised the front of the car and opened the expansion tank cap and then opened the radiator drain plug. About 2 litres drained from the radiator. But that was it. The level on the expansion tank didn't go down. On my old e39 530d I would open...

    Hi, bit of a long post but here goes... The car had the timing chains changed and walnut blading for the swirl flaps. This was causing bad performance and harsh gear changes. Before it was done we had not had any issues with the car and before we had it done we had. It scanned for gearbox...
