Thinking of setting my car on fire

So I'm having issues with the front left wheel sensor, Audi A4 1.8T quattro 6sp.
Got a cheap Chinese brand, bad idea.
Cleaned the sensor ring, and everything worked fine for 2 days, now all the faults are back, ABS/ESP light. Put the old sensor back in, ran OK for 1 day now all the faults plus a new one are back. I've tested both sensors and they're both duds. Cheapy, gives 1.6k OHMs, orig gives 1.7. Magnet in knockoff is now as strong, copper wire is thinner. Orig part doesn't put out voltage when turning wheel.
I'll have to go down the genuine Audi part route, to see if that cures the issue.
Old fault is: [FONT=Verdana, geneva, lucida, lucida grande, arial, helvetica, sans-serif]00283 - ABS Wheel Speed Sensor; Front Left (G47) was intermittent, now is showing open/short to positive. [/FONT]
New Faults I'm getting are: 01312 Powertrain Data bus, fault to sporadic. This fault shows in the comfort module and Auto HVAC.
If I clear the comfort module fault, the ABS/ESP sensor lights illuminate and set a fault. Often while sitting with ignition on, engine off, not moving and scan tool connected. ABS/ESP will illuminate and set code. No chimes are ever heard, when at rest or during driving. Car is taking longer to start.

At the moment I am thinking it is a dud ABS sensor, as this was the initial issue. I have visually checked the sensor ring and can see no evident cracks or other malfunctions. When I cleaned it up, it ran fine for 2 days, with cheap part. At this stage I think it is the dodgy sensor that is causing all the problems, especially if it is a short to positive. (checked wiring, and connectors and ABS module connector which was dirty, and cleaned with electrical contact spray. Cleaned battery terminals. Might be a dodgy ABS sensor to wiring connector.)
I'll keep you posted.
And if I do decide to set it on fire, I'll post it to youtube.
 
Well after doing some actual research, I know who does that in this day and age!
I found out that my cheap Chinese knock off didn't work because while similar outside. It wasn't the same inside. My Abs sensor is the inductive type whereas theirs was the passive type. Which is probably why I got all the extra codes. I only found this out while looking at the Meyle website. So while it appeared on the outside to be an 8E0 927 803B is was actually the A variant

So one original part later (ABS wheel speed sensor). Still not sorted.
ABS and ESP light comes on when sitting with ignition on not running. Still showing open circuit/short in ABS module, also showing vehicle speed sensor in ECU and Powertrain Data bus error in Central electrics. Also will not start on first turn of key like it used to, now you have to turn key and 'attempt' to start, then ignition off then on again and start. I think my ABS module is Kaput! Also my crank angle sensor could be dying again.... ugh. Any tips would be good.

Try gasoline and a match :_b:
 
I need a bit of assistance re ABS module pin out. I have found corresponding pins for the ABS 5.3 G47 wheel speed sensor to J104 module. But wondering if the 5.7 pins are the same, pin 8 and pin 10 if I'm reading it right. I'm trying to see if there is a short or problem with my wiring from where the sensor wheel well connection to J104 connector.
. see picture.

This may end up being the cheapest option to fix my current woes!

So I replaced the crank angle sensor. It threw a code and the bolt housing was broken, fixed a broken vacuum hose. Then found a leaking heater hose from the flange ugh! Still hadn't fix my original probs though. But I have some parts coming that may do the trick.

I didn't end up setting my car on fire. Found numerous dodgy vacuum lines and fixed them, which in turn corrected the mystery illness it had acquired.
 
Vulkus...

You lack patience, at least when it comes to cars. You were prepared to burn down your car, because it had persistent faults?? It’s not the car, it’s your method of diagnosis.

Oh well. I’m glad you got it fixed, and another Audi escaped a fiery end.
