2004 Golf V 1.9TDI (105 hp) engine ecu( eng code BKC )

[z786]

Car complains of engine speed sensor fault, has been replaced twice.

iv read somewer that there is a fixed flash file available for these

if some1 can supply it would be great

thanks

what's hw and sw number?

[macxlulu]

also once fought with this problem, these engines were 3 types of sensors two gray and one black, you have to perfectly fit the sensor, in my case I had a substitution of some of the same and also did not work, it was only later I put another and work as you had gray you have a 50% chance of you can match the correct

[z786]

here is the flash file from galletto

v1037369564
.0281011478
BPG-81031.01.04123456
818840651.
.WVWZZZ1KZ4W075522.
.0281011478
.R4 1,9L EDC

can any check for me plz

[macxlulu]

remove dtc codes will not solve the problem

[z786]

the car has had 3 crankshaft sensors
in ross tech wiki it shows that these ecu's have been given a new upgraded flash and also given extra earth installation

[grinovsky]

the dump that you sent is 100% original
may be you have probleme with wires!!
i don't anderstand!! in 1st post you speak about speed sensor fault
and now you say 3crankshaft sensors was remplaced
they are very different this 2 sonsors!!!

The Engine Speed Sensor (G28) is also used as a reference sensor for the crankshaft position and correlates with the Camshaft Position Sensor Bank 1 (G40) and Camshaft Position Sensor Bank 2 (G163).

see section special notes
16705/P0321/000801 - Ross-Tech Wiki (http://wiki.ross-tech.com/wiki/index.php/16705/P0321/000801)

[grinovsky]

dtcP0321:crankshaft sensor
chek 5v betwen pin1 and pin3
pin1 crankshaft sensor--------pin B42 ecu (+5v)
pin2 crankshaft sensor--------pin B58 ecu (signal)
pin3 crankshaft senso________pin B57 ecu (gnd)
if the probleme is in flywheel (volan moteur) you shuld see the signal by using osciloscope to make diagnostic
no relation with speend sensor

[z786]

so whats the speed sensor then mate

[grinovsky]

the speed sensor is emplanted in gearbox to mesure the speed of the car when move(km/h)
and crankshaft sensor is emplanted between engine and gearbox to mesure the speed of engine(rpm)

[z786]

im sorry mate, going to have to disagree with you on this one

on a VAG car, the "Engine speed sensor" IS the crankshaft sensor as it gives the ENGINE speed, not the vehicle speed, the vehicle speed (k/mh) is taken from the ABS sensors

i even quoted you a section from ross tech and gave you the link

"The Engine Speed Sensor (G28) is also used as a reference sensor for the crankshaft position"

Hello Dear DK FRIEND (z786)
1) I dont know if you use scan vas ? this device is verry imported about your problam ,you can use (guided fault finding) & in this test you can get all information or manual about you fault & how you check all sensors ,and in the system can you do update ecu if your ecu needed update,
so i wish for you Good Luck.....

[z786]

iv used VCDS which is the next best thing

car while driving cuts out, then doesnt start for ages

it gives error code for engine speed sensor no signal

from the research i have done it shows engine flash needs upgrading

heres the sections from rosstech site

"When found in a 2004 VW Golf, Jetta, or New Beetle with 1.9l TDI-PD (BEW), check for TSB 2010461 (01-07-45 formerly 97-05-03) or 201463 (01-07-44 formerly 97-05-04) calling for a flash update to the ECU and a secondary ground installation."

Has any1 got an upgraded flash please?
or any other solution

[mastaflex]

sometimes this fault is not caused by the sensor itself and you replaced it twice. it happen to me once on a GOLF MK4 and the problem was the target on the flywheel. but to inspect this you have to remove gearbox and see. for my case target was totally damaged (how ? don't know)

[z786]

the reason why i think flywheel is ok is because sometimes you can drive car for days without problem, you can drive it as fast as you want without problems

Hi Dear,(Z786)
1) if the car still with you, plz drive the car after when cut the engine stop working. plz do (auto scan) with VCDS end post in dk, maybi i can help you Dear,but i thing you check all the electrical wires from (G28 sensor) to (ecu J248)?.if all connection is good & Good grownd - on ecu, it mean the problam in (ecu j248)
Good Luck....

[z786]

evrything has been checked hence i have requested a new file

[z786]

problem solved, broken fuel line lol
any1 here can help me get more BHP out of this dump plz :D

[teuton]

any1 here can help me get more BHP out of this dump plz :D


For sure mate, but you'll have to tell where the heck you found that second bank which sensor you mention in post #8.
:hmmmm: :tee: :hmmmm:

Hi Dear (z786)
1) nice you are near the problam, good.
2) to be sure if the ecu he try to gut the line of (relay j17) plz try to connect the 2 pins of (relay J17) number (1) blue/red & number (2) red/yellow, togeder and drive the car if the problam solved or no. number (1) is give you 15 positive. & pin number (3) on the (relay j17) black/brown ,comming from ecu you can give direct positive to know if the ecu cuting this line.
the location of (relay j17) you have 2 models (1) lef under dash panel,e box low, (RELAY 4). (2) near the battery you have fuse box , (number A3)
so if any new we are ready to help ......
Good Luck....

that was a quote from ross tech website mate, i have no idea where second bank sensor is :)

it was a broken fuel pipe mate, leaking.

he cant !
this type of engine has only one cmp and one ckp.
the car will start without cmp but will have a bad startup ; the reason is that the cmp sensor is used to syncronize the injection timming, you can test your self: pull out the cmp socket and you will have a poor startup and no injectors corrections. the explanation is simple: using both sensors the engine needs to make half of the revolution nomber to know wich injectors comes next in the line of injection comparing to just using one; think about the crankshaft/camshaft ratio!
more information about this you can find in the vag com lables !

with a faulty ckp the car will not start eaven if cmp is good.

there is no solution for fixing a faulty cmp/ckp sensor if ecu reports this problem, maybe what you heard is about a hesitating one for hot regims! that can be done via flash

anyway it seems in your case the problems was a little more simple :)

ps: for this type of car/engine when you have problems with speed sensors just check the wires, it has really bad habbit to f ..ked them up (under the baterry area!!!). i usually dont try to locate where they are broken (wires), i just change them, is far more simple!

regards,
tr@ns

[z786]

any1 gonna help me raise the bhp on this file please? :)

[allnamesused]

i had a similar problem ona similar car,turned out to be the cam timming.
what ecu is yous edc16u34?
