First check the fluid level and make sure it is correct. If it's good you will then need to go to the dealership to have the codes pulled. I hope the problem is the fluid because it will be expensive otherwise.

replace oil,check oil pressure with external gauge, if ok replace oil pressure sensor. if not, then there is a engine mechanical problem

Question edited for clarity. Question moved to model category. Check out the videos, and also already answered on Fixya https://www.fixya.com/cars/t6734476-crank_sensor https://www.google.com/search?q=2008+audi+A3+2.0+tdi.+crankshaft+sensor+location ..

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.

200 RPM are you sure?

I think the seat belt have a twist and it went into the seat belt housing. Pull the seat belt all the way out hard and un do the twist and let it go back into the seat belt housing. This should fix this problem

Hi it could be number of things it can be faulty gear box faulty solenoid faulty ECU computer. need to plus it in with diagnostic computer thanls

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem. I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything got it from www.reliable-store.com

At this website www.reliable-store.com I found all complete guide,much better language, complete detail in 800+ pages, ..and they also have live chat for instant help feature
