HI MATE
my VW Polo has similar problem, the instrument gauge went blank on new year eve, as a result i couldn't start the car at all..after a while i smack the instrument gauge came back on, then car able to start then,but the airbag lights stays on, since then the instrument gauge seems to go blank(disconnected?) in 1 sec and come back on...i have posted several msg here but i have no joy getting any expert advice. i have booked in for a
service next week and will let u know how i get on.
in my opinion i think theres chance the fuse got a problem or a loose cable.and last it can be a faulty instrument gauge.

HI THERE, just got my polo back today and garage says they couldn't fix the problem as the faulty dashboard working ok while in garage after they reset the system. the only solution they offer if problem happen again is to replace the dash + labour = €450.

i reckon its only a bad cable as the dash working ok, except its shut down and restart once a while. they reckon resetting the system should eliminate the problem.

Hi there

Thanks for the info re your dodgy polo dashboard. My Sharan is still exhibiting similar problems despite the fact that I have checked and double checked the wiring and the pcb's for any obvious faults.

There is one electroletic on the board, which when pressed and proded momentarily clears all the faults. However when everything is re-assembled the fualt reappears.

I tend to agree with you that this is a simple fault that should not necessetate a new instrument cluster. You say that your garage have reset the dash what exactly did they do?

Cheers for now

they have checked all the warning lights that is on, currently the airbag lights was on, they plugged the car computer with their diagnostic system and couldn't locate any fault, so as the end they reset the car management system so no warning will stay on, as the airbags light isn't caused by airbag fault.

i told the mechanic on duty as he also agree that sounded like a bad wire but he said the problem not showing while car in garage.
so he adviced if same happen again will have to replace the instrument cluster.

"this is almost like doctor have to amputate my leg b'cse i got a blocked artery somewhere.."

Hi and thanks for your recent response.

I guess I will now have to book my Sharan into the garage and suffer the financial consequences of having a new instrument cluster fitted, but will it cure the problem?

HI MATE
i finally found a Instrument technicians that know their stuff, as i mentioned the problem and they immediatedly came back with few possibilities and solutions. you should check out any Instrument technicians/specialist in UK, as far as i know theres lots. most cases instrument cluster can be fixed if its a digital error.
it took me ages to find one here in Ireland and personally replacing the dash isn't best solution unless they can pin point the cause.
anyway those guy quoted me half the cost to get it fixed and a 6month guarantee on the faulty dash. will see them sometime next week and let u know the outcome! good luck

Cheers for now
