2001 jetta ecu bricked?need advice

[mike88448844]

ok quick background 2001 jetta 2.0l manual this vehicle has been problem free since we got it 3 years ago my wifes daily driver.so she left work went a block to another store shut it off 5 min later comes out no start cranks but no start had it towed home checked codes with gen scanner and got no comm code i bought hex net ran codes and got 01314 ill post my auto scan.anyway threw a new fp in it because i couldnt hear it when i put the key in.im a fairly competent mechanic bodyman by trade computer literate used scan tools ect the known facts are no one has been under the hood for about a year since vw dealer did a new ( lost key)it hasnt missed a beat i opened the ecu nothng burnt nothing even looks like a heat issue could the ecu have lost coding or something like that? thx

 

[Quintus Rotam]

... ill post my auto scan.

Hi Mike,

this would surely be the best way to get the diagnostic ball rolling around here.

 

[vwtech]

I suggest Auto scan and checking all power and grounds at ECU.

Good Luck

sorry about t
my first post i was having issues with my computer anyway after my first scan i went into the abs moduleand saw the miscoded module(my first clue that the ecu may not be toast)i ran another autoscan and a bunch of codes went away.so i think my question is about the power train code could that be just a shorted wire?any help is appreciated.

 

[Quintus Rotam]

Hi,

There are people anxiously awaiting your Auto-Scan in the original thread. Since both threads are about diagnosing the same vehicle, I don't see the benefit of this spin-off thread, especially when the original thread started to look quite cheerful. I sense a thread merge in the future...

Wishing you quick and easy resolution of your issue

 

[vwtech]

Again Check power and grounds to ECU is first step. Power supply relay to ECU was probably the cause.
Don't see the reason for starting a second post?
I would now check power and grounds to TCU.
Clear codes and see what return.
Good Luck

 

[Uwe]

I sense a thread merge in the future...

Prescient, you are!

-Uwe-

 

[Crasher]

That second scan is of an A4 cabrio quattro...

 

[mike88448844]

sorry ive been having an issue with posting im not sure if trying to post two scans is toomuch and for some reason the second was the wrong scan and i wasnt able to delete it from my post i didnt get a reply box on my other posts (im pretty sure its my word program) im going to try to attach my latest scan and then off to check grounds..thanks for the patience...... well i guess not i cant paste it move or copy to this program so i think i need to get a newer computer as soon as i am able to post to this program yesterday it posted too much today nothing

 

[Jetta 97]

In First scan There is no communication with Engine computer ECU . You need to check and make sure you getting all 12V and grounds to it before you get other ECU .
It is possible that ECU is bad , but need to be 100% sure not just guess.

 

[mike88448844]

Ok so i realized i ddnt have everything on my end done ect, im better prepared now so im posting a scan of my jetta with the bad ecu and then with the new(to me a wrecking yard part w/matching part#)since last post i sent my old ecu to an elec repair shop to verify damage,results were water/ condensation damage to the cpu. so now i am to the point where i need some direction i checked grounds and power ect now the new ecu is in.... where to go from here.. i think need to retrievethe pin from the new (used ecm)but im not sure of the order of the steps i need to take to install the new ecu thanks everyone

I have to attempt to code a used ECU into a Golf 4 next week so I will tell you how I get on.

easiest way is for part number to be same and immo off it

IMMO3 and it does the handshake over CAN. Although neither the ECU or instruments are complaining they can't see each other, there must be some corruption on the Powertrain CAN as reported by the numerous ABS communications errors.

Please report the following MVB:

01-ECU:
MVB - 125
MVB - 126

17-Instruments:
MVB - 020
MVB - 021
MVB - 022
MVB - 023
MVB - 024
MVB - 025
MVB - 125
MVB - 126
MVB - 127

When displaying each MVB, click the [Add to Log] and post text here as you do for an Auto-Scan.

Why not . ? Then you could start it just like in the movies . Those scenes where they rip off the contact wires on cars made from 2000 and up and they start the cars are cracking me up . You couldn t start a damn Chevy Aveo like that

Especially the size of the sparks those little wires always make in those scenes when they connect them!

If I watch a film that portrays that on a car I know has a factory immobiliser it ruins the film for me; maybe I should get one of these actors to come and get this flippin A4 going!

From what I read about that car, you're making a horror movie (German producers, British actors).
Those usually feature some scantly clad girls, so I'm already picturing that Stasi lady.
