Diagnosis Problem

[sedgers]

My pilot light for the breakdown of an electrical system in the engine has come on, gonna go back to the guy who has the VAG-COM to see whats goin on but anyone for ideas????

is it just my cupra 20vT that always lights up different lights???? the dash looks like a disco!!!!

vagcom should tell you the problem.. it could be any number of things

 

[sedgers]

seems that as soon as the engine gets warm in hot weather or long drives it decides it wants to light up and say summing wrong, luckily i found a local guy with a VAG-COM who dont charge the earth for a check!!! seeming to be an expensive motor now only had it just over a week had an EPC and Diagnosis pilot light illumination

bug a vagcom lead.. about £20 from ebay.. and download the trial software for free.


my latest EPC light was for coolant temp sensor, it cost about £23 to replace.. and abotu 3 mins work.

 

[sedgers]

my EPC was temp sensor, the new problem is the diagnosis light. i didnt need to replace the sensor because the VAGCOM reset of the ECU sorted that problem. hope it can do the same to this one. fingers crossed . . .

 

[claudefrog]

you might find that its come back again.. and will need to be replaced

it could be alarming to say, "still faulty, replace me"

 

[Jonzy]

Just because you cleared the fault with vagcom, dont mean the problems gone away.

 

[sedgers]

guess what, u guys were right!!! stupid sensor is bust and sending wrong signals. anyone know where on the engine the temp coolant sensor can be located and estimate as to how long it will take to fit?? it has flagged up as an EPC problem and now as an engine management problem so think its time to change it an stop just clearing the code cache

 

[claudefrog]

its to the left hand side of the block , its connected by a plastic clip, takes no more than 3 mins to fit, no tools required.

if you take the engine cover of your car, take a pic of the left hand side I will point it out to you.

Ive zoomed and cut a section so you can see, its the faint green thing in the centre of the zoomed bit.

Can see the top of the plug clearly in that one.

 

[sedgers]

Fantastic and its just a plug and play joobie!! u guys are amazing, u really know your stuff!!!! thanks for the images jonzy makes my life much easier!!!

 

[Jonzy]

Wait till the car cools down, take the header tank cap off to relive the pressure.

D/C the plug on the top of the sensor, pull the big C clip out sideways and pull the sensor up and out. Just do the reverse to put it back in. Might need vagcom to clear the stored error again.

 

[sedgers]

oh btw jonzy, ur engine looks sweet!!! shame i cant mod my engine being 18 and all, it would be an insurance field day!

 

[Jonzy]

Mines not the blue one, I just found that pic

 

[sedgers]

should have played along coz that one does look sweet!

 

[Jonzy]

It does, mines the grotty one in the 2nd pic

Sedgers, dont forget to swap the little rubber o-ring on to the new sensor when replacing it.

thanks martyn (feels weird spelling someone elses name my way i thought i was unique!!). gonna be my first DIY job on the cupra. . .used to pull the fezzy to bits and try to fix that but little more careful with the cupra . .my girlfriend thinks i love it more than her . . (sometimes, so do i!!). cheers for the advice.
