Audi A3 1.9TDI 8P Oil level and temperature sensor fault. Fault finding and repair.

[@soulreaver4621]

I had the same issue with my 2006 A3 Sportsback. My fuse number 5 would blow immediately as soon as I replaced it. The root of the problem wasn’t in the wiring or the sensor itself. Initially, I didn't realize that but alongside the oil level sensor error, the AC pressure sensor and reverse gear lights had also stopped working. When I checked with VCDS, I saw an error indicating a faulty AC pressure sensor, but there was no mention of issues with the reverse lights. To troubleshoot, I have disconnected the AC pressure sensor plug, and to my surprise, the issues with the oil level sensor, reverse lights, and the blown fuse all resolved themselves. It turned out that the culprit behind all these problems was indeed a defective AC pressure sensor. This experience serves as a reminder to carefully investigate interconnected systems when dealing with electrical issues in vehicles. This took me a week of my life and a ton on searching.

Indeed! Always investigate anx understand how things work before start to replace parts... 👍👍👍

[@vladuttrofin262]

Nice solution.I disassembled the whole car A4 B6 for a melted wire(who said that a wire can affect a bunch of wires. ..).Keep up the good work!

Great solution! VAG cars are realy hard with the wires build away I had this once with a Mercedes A 108 who blowes the immobiliser fuse and replaced the whole wire.

Indeed! The labour involved to trace that wire would be enormous... At least got it all working! 👍

[@hamadyousef8728]

Most best solution.. for money, time and efforts .. i wish you showed to us the finish about how you added the wire to another fuse is it like a pro or just pull out the fuse and put a wire beneath it. By the way i read about people who said its wrong ... i laughed because you showed the solution but if he was the technician and wants to find the problem be will never ever find it .. again thanks sir for your efforts and best wishes.. I had like these problems everyday and you should be a genius to solve' em 😀😀😁😁.

Thanks Hamad... I have proper soldered the wire underneath... I know was not very good I could not show it... but was i have explained in the video... 👍👍👍👍

[@sputnikas]

If it works, it works! By the way, if you don't want to fix it, it's possible to disable it with VCDS (or other scanner) in Instrument cluster module (Adaptation>"Oil level sensor adaptation" and replace "1" with "0")

[@LMAutoRepairs]

Correct... Thanks!

How do you bypass it full stop? Could you cut and connect two wires on the loom or?

Not sure you can bypass it... You might be able to do it through coding though... I never tried... 👍👍👍

Hi I got this same issue , I’ve done the checks and have got 12v into sensor and 2.4v out of sensor to cluster , but can’t find where the earth goes , I really need to find terminal 50 relay I have looked but cans find sensor earth

[@LMAutoRepairs]

Somewhere by the left headlight... 👍👍👍

[@lucanturner7435]

Hi thanks for reply , am I looking for a relay or a bad earth ? By the left headlight? Also can I connect an earth to the cluster somewhere , like you did with the 12v ? I found sensor ground on the cluster pins but there’s no continuity to earth , could I just earth it to body ground? Thanks in advance

[@LMAutoRepairs]

@lucanturner7435 You are asking too many specific questions... lol Check diagrams, and see how everything is connected, from there you can figure out any possible connections... Grounds are just grounds... they don't go through relays... 👍

What do you think the voltage would be on pin number 3 ?

[@LMAutoRepairs]

If the sensor communicates with a LIN bus signal, with a multimeter you will see 12v or so... but to really check properly you need to check it with an oscilloscope... But I am not sure if it is a LIN bus connection, never researched at the time... 👍👍👍

I can't get to the bottom of this on 09 tt8j, same cluster as a3, white dial's, i even give the new sensor ( 3rd) direct live and earth from battery and cut the signal wire on the cluster and ran a new line directly from cluster to sensor, still no good, tried different cluster because I thought that might be the problem, sensors are oem (hella) i read the eeprom from cluster and tried to find the switch in the cluster dumps, can't solve this issue, no fault codes 😢

I had a similar problem with an abs system, I bypassed the wire from the offside rear wheel (signal wire) and connected it directly to the abs module, problem solved.

[@LMAutoRepairs]

[@timmehlittleloud2251]

I notice the steering wheel was fully extended. This fault is usually a shorted wire above the moveable column. Proper pain in the arse to get to. Also, no amount of ragging the wires about gives you any clue as to where the problem is. This fault occurs due to the superior German build quality.

[@wires4auto]

Hi, I noticed the aftermarket equipment and I wondered if they had tapped the power out wire from the back of the fuse box. I have done this on them Audi's when fitting trackers. Would be worth a quick look.

[@modestasserpenskas2353]

Hey. I have a suggestion for you, the easier way to find a short circuit wihout burning fuse after fuse. What i doing in those situations, i take out burned fuse. And put h7 light from low beam, doesnt metter. ofcourse with two wires. so if the light shines bright then i know its a short circuit. but as soon as you unplug something or find a problem, the light turns off, sorry for my english. :) cheers

[@LMAutoRepairs]

That's a really interesting concept! I might do something with it... Thank you for watching and for your comment!

[@modestasserpenskas2353]

But it's important to use h7 light and it should shine as bright as possible. Then it's a short circuit, because the smaller lights sometimes can still light up even tho there isn't a problem at all. Even h7 can shine but ofcourse not fully bright. I hope you can understand what I mean.

[@83554]

Hi L.M., I have followed your instructions for diagnosis, this is what I have, I have 12v on power line but when I check signal, the voltage is fluctuating between 5v and 0.5 volt, constantly fluctuating, no fault codes and oil light always on, oil temp is 0 deg. any tips, cheers

[@LMAutoRepairs]

Where have you checked that, at the sensor, or at the ecu?

[@83554]

Why is signal to cluster fuctuate ? I can't figure out L.M.

[@83554]

Sorry L.M. I checked at the sensor on the sump, with ignition on and sensor disconnected, I get on cable 12v ok/ gnd ok, but on signal 10.5 v When I connect back cable to sensor, normal 12v and gnd but signal is fluctuating, I'm really lost here L.M.

[@LMAutoRepairs]

@albrrt430 Can be a bad sensor... That's why I asked, those measurements, were taken at the sensor plug, or at the ecu plug? Missed your last message... Measure at the ecu plug, to ensure wiring is good... If ok, I would suspect the sensor...

[@83554]

It was fine before I installed new oil pump, I've tried 3 different sensors,, I even changed the cluster believing it may be fault, I will check the ECU, thanks L.M.
