1808 coolant fan control 1 open or short to ground p1672 no signal /no communication. its had s3 front conversion so the double radiator fan is only running one fan

No idea without a play but i do know these engine do suffer from head gasket problems on no4 cylinder other than that i would need my head under the bonnet sorry for the indecisive answer

FOLLOW THE WIRES OUT OF THE BACK OF THE FAN MOTOR UNTIL YOU FIND A CONNECTOR AND PULL IT APART.

Time to have a mechanic diagnose it...judging by your description...do you race the vehicle??? is it well Maintained??? Did you buy it new??? have you had the timing belt, and tensioners replaced??? If the timing belt gave way, and there were no funny noises, that means your car has a "non interference" engine, which is a very good thing...find a mechanic that you, or some of your friends trust, and let him/her take a look at it...you might need to leave it for a while...good luck...

NO THE PROBABLE CAUSE IS A VALVE THAT ADJUSTS THE TURBO PRESSURE!CHECK FOR DTCS FIRST AND LET ME KNOW!!

The following asumes only one wheel is hot and the e-brake is not engaged or possibly hung up from having been left on while the car was not driven for a while. Up north, BMW (Audi ?) brake disks tend to start rusting after about a week of inactivity. For a hung up e-brake, it is sometimes necessary to go back and forth to break the corrosion. A hot wheel usually indicates that the brake pad is dragging (i.e. the brake caliper piston is not returning into the brake caliper bore). A couple of checks: measure the brake disk temperature with a temperature gun on both brake disks of the same axle. If one is much higher, the caliper piston is probably sticking. Can also check for relatively large temperature difference with your hand-just do not touch the metal or you will get burned. Look at the brake disk for evidence of the outline of the brake pad that may have transferred to it indicating a very hot brake disk. Chock the car well, put into neutral with e-brake off, jack up "hot wheel" side and try to spin the tire. If a lot of drag, sticking caliper piston. Caliper replacement or disassembly for a thorough cleaning will probably be required. If this is necessary, you should do both brake disks and pads and consider doing both calipers on that axle depending on age and corrosion condition.

If you have replaced 4 sensors the problem must be somewhere else in the system. Exactly which sensor is it as there are many sensors built into an engine and transmission? You could get a Good Auto electrician to check the vehicle to see if there is another cause of the problem.

crank sensor fault

It could be a few different things.
Did the check engine light come on before it quit running?

Most likely the disc player has a failed loading system, very common, pull it out and have it rebuilt.

No injector relay in this car. Injector pulse is controlled directly from ECU.
