Title: ED30 Exhaust light
Post by: Thestig1973 on October 18, 2009, 08:06:22 pm: Owned my Edition 30 for 1 week, under hard acceleration the car hessitates then flies, today the car hessitated then the exhaust light flashed then stayed illuminated (i pressume the ECU sensed a missfire)

its booked into VW in the morning so i am hoping its all covered under warranty (3 year Warranty expires January)

Any of you chaps experienced simular problems ?

P.s. absolutely love the car but just want my baby to be well again !

Post by: Thestig1973 on October 18, 2009, 09:21:07 pm: i was guessing either coil pack or fuel pump

if the coil pack is faulty would it not missfire under normal driving ?

Not necessarily...

Post an update when you get the car back.

fault code showed missfire on cylinder No.2, so swopped coil pack (2 & 4) to see if cylinder 4 now missfired

went back to VW a week later and fault code showed missfire on cylinder 1, 2 & 4 !

service book stated spark plugs were not renewed at last service so renewed plugs (just short of 50 notes)

All seems fine now

cant be certain till its been on rollers but it is very quick, my last few cars have been around 230BHP (Mondeo ST220 & BMW 330D remmapped to 235Bhp by chipped uk) and the ED30 is much quicker :happy2:
