So my mk4 1.8t golf (aum) was running fine, its low mileage (81k), recently serviced, well maintained etc.
However its recently started to play up. It starts intermittently, sometimetimes the clocks dont light up at all, sometimes they do and it wont turn over, sometimes it turns over and wont start.... I'd say it starts 1 in 4 times and then it runs fine. But its getting worse :sad:
I have scanned it and it came up with a lengthy list, I forgot to clear them and when i scanned them again (minutes later) it came up with a few more!
Within that time i had started the car and the clocks displayed ''oil sensor workshop!''.
The scan came up with a variety of codes so am a bit confused as to what it could be? clocks? ecu?
Any help would be greatly appreciated! :smiley:
Cheers

if you go here

find the number you want to know about and it gives you the same as what the laptop reads as well as easy to understand terms, and possible ways to fix the issue

Thaks for that :smiley:
I have a feeling i may need new clocks as they were playing up a few weeks back... it definately seems to be an electrical fault, most of the codes point to 'CAN-Databus Wiring/Connectors from/to Engine Control Module'

How old is your battery?

How old is your battery?
a few months, it kept dying last winter so i bought a new battery but maybe it wasnt the battery. Although even after a long drive it does the same thing. the reason i think it may be my clocks is because the display was flickering whilst driving a while back...
-
sounds like the ecu has died tbh mate

Thanks for your reply, though I was worried someone would say that... Is there anyway to test for sure?
-
there are a few codes there that all have the ECU in common, i think it may well be an ECU issue too, not sure if you can get a new ECU coded into the current immo setup or maybe just have the immo removed from it all together, it is making me wanna scan the wifes car now though as her clocks started flickering a couple of weeks back
-
im not sure on weather there is a check for the fault of the ecu but the fact that its throwing out loads of codes usually indicates its died, like miggs2002 said you can have an ecu coded into the immobilizer or you can but a second hand ecu, transponder and chip
-
If the lights are flickering I'd suggest looking to make sure the alternator is working correctly.
It's very unusual for an ECU to bite the dust

It may be worth a go mate, for peace of mind!

right, so it may be worth getting the whole setup if i can source someone who is breaking an aum, if the clocks were on their way out anyway.
As an after-thought, there is a clifford alarm/immobilizer system installed by the previous owner, could this be causing some of the issues?

Would they be flickering whilst driving if it was the alternator? It was the mpg display that was flashing (a few times a second) rather than the management lights...
-
Yes they can flicker whilst driving as the alternator is not putting the charge back into the system
Also check the terminals and fuses on top of the battery as there could be an intermittent contact.
Start with stuff that's free and easy to check :wink: Most garages will do a free test on the charging system.
-
i believe that if you have immo2 clocks or earlier then you can fit any mk4 clocks into it as only the immo3 ones have the immobiliser in the circuit, i have never tried this and don't know just how true it is but if you have any friends or family with a mk4 you could always try the clocks, just takes a min to remove them
as for the flickering, it the whole clocks on the wifes that flicker, if yours is just the fis then it may just need re securing, take the clocks out, remove the back, now on the circuit board there is a metal cage that will come off the board with the tist of some metal legs, if you search it on google there will be a guide of how to fix mk4 fis display as i used it for mine some time ago but have forgotten exactly how to do it
as for the clifford, it all depends on the fitter, the mk3 onwards was fitted with a factory immobiliser, some fitters use the standard immo wire in the aftermarket alarm to that others make use of the separate immo in the new unit this giving you 2 immobilisers in 1 car, it's highly unlikely that an after market immobiliser is the issue unless it's wire in to the factory unit, without checking the wiring of it all it's hard to say which way round it's been done

cheers mate, yeah im gonna go out and give a few of the terminals a clean as one on top of the battery has oxidised a bit, check the fuses and generaly peer around to make sure everythings tight too :smiley:

Ah right, so if i already have immo2 clocks i dont need to code in the new ones? unfortunately I'm the only mk4 owner I know! :rolleyes: But I'll definately have a check of the fis and make sure it's not loose.
The clifford uses its own immobiliser, i have to disengage it on the fob before turning it over.
this car business is never ending! :wink:
-
do you have a non immobiliser key to see if the key will start with the clifford disengaged but no mk4 immobiliser chip? also with regards to the clocks, i have never tried it with my own as i have and immo2 car and an immo3 car, i have removed the clocks to fix the fis in my immo2 car and when i went to move the car with the clocks out it wouldn't work as the clocks were out so i'm not 100% how true that is, i can try it with both the cars but it will be Sunday before i get chance as 1 is the wifes and she works from 6.30am till 10.00pm so it's a bit late to be messing with stuff like this on the drive lol

haha :grin: yeah that would be great mate! I dont have a non immobiliser key unfortunately, i thought i read that you need to have the clocks coded in with a secret code you have to obtain through vag-tacho, but i could be wrong?
-
started p*ssin it down when i went out, but think it may be down to a dodgy alternator connection...

i have read the same thing on one forum then i read the immo3 clocks are the only ones that need coding if going into another immo3 car, not sure which is right so will just try it when i get chance

that's the puppy, dunno if it'll work for you as some people get different results

So I cleaned the alternator fuse/connection (the box is a bit melted where the blue tape is).
I also removed my clocks and turns out it has a different screen to the metal cage one in the guide but all the connections seemed alright there.
I checked my earth connection under the battery, that was fine, and I removed the battery to reset ecu.
Nothing changed though i did notice that the fuel pump wasnt priming so i changed the fuel pump relay (and uprated to the 'c' one) and it is a bit better.
However I noticed a pattern, if i put my key in and turn it the clocks are dodgy still and the fuel pump doesn't prime, if i then turn it off and turn it back on without removing the key the clocks are fine, the fuel pump primes and the car will start. Though if i turn it off and remove the key before trying again then the clocks still mess up.... :undecided:
very confused now, any other ideas? I may just end up changing the clocks to rule them out!
-
i took the wifes car out last night and had noticed that the dash clocks flicker but (and i don't know why i didn't think before) the climatronic screen doesn't, this, in my case anyway, means it's solely a clock electrics issue not a battery/power issue, do you have climatronic? might be worth keeping an eye on it

I don't have climatronic unfortunately, i think it must be something in the immo system. It feels like the immobilizer either stops the fuel pump priming or stops the car turning at all. Other than changing the clocks I'm at a bit of a loose end, if the faults are indicating CAN-BUS faults could the clifford system be wired into that loom causing problems? I'm not too clued up on electrics if you havent guessed! :grin:
-
i'm crap with electrics too to be fair, if you think it might be the clifford then it's not too hard to uninstall it, just a nightmare to re fit
-
True, i wouldnt refit it though so thats alright.
The abs light and traction light are constantly on now, and there is an exclamation mark in a circle flashing red :undecided: so maybe something wrong in the brake system...
I may have to bite the bullet and take it to a garage, everytime I think of something it could be something else crops up :rolleyes: it could get expensive changing various components ruling stuff out!
-
brake pad wear sensors, check pad thickness, also brake fluid low? 2 things that are free to look at
-
cool, i think my fluid levels fine but pads may be a bit worse for wear! will have a check of them asap! :wink:
