P3054 jammed or eletrical starter module

[smatch]

Hello

Audi A4 B8 2.0 TFSI
stopped running no drive

Only one error in VCDS
P3054 starter module jammed or mal function eletrical

Vídeo problem https://streamable.com/9tm6qi

Only this error on VCDS, but I try run crankshaft by hand with 24mm and is impossible.

Sound like starter module? Fuses all is ok!

Thx all

Yeah either starter is extended and wedged in the ring gear, or the engine is locked up. Hopefully the former

[Theiceman]

I would say more likely engine is seized.. you dont state how many km on it ..

obvious next step , remove starter see if crank frees up
I hear of lots of engines seizing, very rare to hear starter motor " jammed it " even if it was stuck on, the motor would just turn the starter and burn it out.

Is there any way I can test the starter motor to see if it's the same? without dismantling it

Uh pull the starter out. You're either doing that or pulling the engine out

Oh sorry

It has 134000km.

The starter motor has already been replaced with 60000km.

the engine has been redone all the way up and the bearings have been changed recently.

I was on the track, the car was going very well, until it turned off walking at 50km/h in a roundabout.

and it was as shown in the video.

Is there a way I can test without having to remove the starter motor?

Sounds like you were low on oil, it all slung to the side of the pan and sucked air and locked up. No, pull the starter out

[apeck240]

Also I didn't see there was a video, sounds like the starter is functioning, that's bad news

No, I Think oil no is faulty, This is showing MAX on panel oil level.

[smatch]

Sh*t :(
Very had

I going to test relays now, otherwise I send the car to dealer mechanical profissional again :(

grab a ratchet and try to turn over the engine. I say try because your engine is seized.

[apeck240]

I'd be on the phone with whoever rebuilt your engine if I were you

I called my mechanic and showed the video, he said it's not a locked engine. but he has a schedule full of cars and can only move on the 5th of March.

On the crankshaft? I tryed this… with 24mm ratchet… impossible turn crankshaft only move 3cm, by hand

[smatch]

This is confused me because on VCDS only show P3054 starter module, lol.

I didn't hear any metal noises or smoke when it stopped

[apeck240]

I don't know what more you want from us, your engine is locked up. Maybe pull the drain plug and see if any cool stuff falls out

[old guy]

Try turning the engine counterclockwise just a very little bit. If the starter is jammed this may free it up.

Just to add to this, pull off the accessory belt and pull the spark plugs. If in neutral and it wont turn, you have some larger problems

You can hear the starter engage and disengage in the video if the pawl gear is not stuck he probably spun a bearing or worse

I believe it could be something in the starter motor since the VCDS only accuses this error.


the starter motor bearing must have seized or broken.
since I tried to start as soon as the car stopped, with it in neutral and started it and lightly.

I think, tomorrow I'm going to take it out, and then with it, the first thing I'm going to do is try to turn the engine through the crankshaft, if it turns I'll be very strange.

I really thank you só mutch for help me!!!!!!

There is no code for the engine locking up. If you try to start a seized engine, the starter won't be able to turn and will give you that code. Good luck

[Theiceman]

grab a ratchet and try to turn over the engine. I say try because your engine is seized.

He said earlier it won't move at all with a wrench

But some data is bad. Also said he can't move it with crank, then said it will move 3cm. Who knows if it was in neutral when he tried to turn it.

Personally I think taking one of these engines to the track is asking for trouble.. as they barely hold together going to the grocery store
But he have to wait for the mechanic if he has not pulled the plugs and put it in neutral to see if it will turn over. Balance shaft seized if it's not a main bearing.

yes guys

I took out the starter motor and the crankshaft did not go by hand.

I won't wait for the mechanic who made the engine until March 5th lol.

I believe I will disassemble the front of the car and start inspecting the balancer shafts.

a doubt I have is, if it's not the balancer axes and something locked the crankshaft such as (bearings), can I take the crankshaft out or change the bearings doing the work under the car? I don't have an elevator, lol.

thanks again everyone's help.

No, engine out to get the crank out. I suggest you don't attempt that yourself

okay so far it is exactly as I had suspected.... you can NOT remove crankshaft from under the car.. the engine must be removed as the RMS flange fastens to both the block and oil pan .. so engine or transmission has to come out.

The next step as you say is to remove the front timing cover ( upper and lower ) , release the tensioners and remove the crank sprocket. this will release both the timing chain and balance shaft chain from the crank. you will know immediately if you have a siezed crank, seized balance shafts, of failed timing components... ( you can probably do it by just looking at the chains but probably best to just get it all off )
Id be going after that engine builder if i could , but we need more details about that .. first things first

Omg Thanks advanced

I need search other mechanic lol
Here on my region brazil citys dont have much specialists on EA888 :(

Otherwise Thanks so mutch

[smatch]

I managed to remove the starter motor.

the engine by the crankshaft is only turning counterclockwise now.

schedule it does not rotate.

[Theiceman]

Sounds like timing failure.

my battery is dead, i will test the starter motor in hand on another battery.


and see how he is.

If he's okay, I'll start disassembling the front myself. f*ck

do everything calmly until you try to find this problem.


I just won't be able to do it at home if something happened to the crankshaft bearings etc.



but the motor runs counterclockwise.

[smatch]

Starter motor tested, working.

should i remove the front to check balancer shafts and current without the starter or can i put it on first? I say because the engine is loose with a support holding it, due to having removed the engine support cushion.

[Theiceman]

dont try and turn it anymore until you get the front timing covers off and see what is happening.. dont bother with the starter, im telling you thats not it.. unless of course you burned it out trying to start the car....

if you cant turn it with a big ass wrench then its jammed for some reason so the chains interlocking it all are next..

[smatch]

OK

thank you so much

I should dismantle the front soon.

thanks

[Theiceman]

you don't have to completely dismantle it , just have to pull it forward some .. there used to be a good you tube vid. let me see if i can find it..

[MyDimeIsUp]

There is also this. I used this video to do my chains this past summer.

[smatch]

thanks for information

I already removed the front as the colleague's video showed.

I locked the crankshaft pulley and I'm trying to take the bolt out of it, I'm giving more than 20 kg of torque to loosen and it's not going! omg

someone has seen this.

the pulley bolt is extremely hard...

[Theiceman]

Yup ... It's a stretch bolt ..
Sometimes takes two . One to hold, one to unbolt

Any reason against using an mid power impact to tap it loose?

They are a one time use only bolt anyway so absolutely not . Sometimes you don't have the access to get the gun in, or the gun doesn't budge it. But otherwise nope.

Hello theiceman, and everyone who is helping.

I managed to remove the crankshaft pulley bolt.
And I think I figured out why I was so stiff, I needed help from a friend and we used our 2 strengths.

The screw for it to come out to the end was hard, and I'm sending a video showing the chain kit and also a problem with the crankshaft pulley screw.

The screw now doesn't go all the way, it doesn't tighten, in the video I show it.

I think here's the problem, in the chain I didn't find any problems, but for now I haven't dismantled the timing chain.

Look at the video and see what the crankshaft pulley bolt looks like, and through his experiences, what might have happened.
