UK-POLOS.NET - THE VW Polo Forum

hi,
i have a 1.2 52plate polo which the ecu light came on whilst driving along.
theres no differance in the driving just the light on the dash.

i have tried the ecu reset, the 3 minute with the battery disconnected, connect back up with tthe door open and turn the ignition on for 3 minutes but it did not work,

any help would be greatful. the exhaust is blowing very slightly at the flexy part right off of the down pipe of the exhaust, i dont know if this could contribute??

i have also recently had my tracking done along with new tyres.

thanks in advance.

The exhaust blowing between the the control probe and the monitoring probe could be causing this, but its only guesswork - you really need to get the fault code(s) read before coming to any conclusions. By the way, you can buy suitable flexi sections online (Senior Aftermarket) and get an exhaust "builder" to weld it into your system - this will be a lot cheaper than a new flexi+cat section. On the other hand, if it is the cat that is dead and causing the fault code then that would be a waste of time, so read the fault codes first - a Gendan VAG scan tool (£40) would let you know what the code(s) are. Also, use the search function here, on www.briskoda.net (Fabia section) and www.seatcupra.net (Ibiza MK4 section) - you will find lots more posabilities for why these engines spit out fault codes.
