Hi guys, i filled up yesterday for the first time with this new petrol e5.
drove 145miles all good,I did feel a slight jerk when flooring to overtake especialy uphill.
all of a sudden the car started misfiring and went to limp mode, i pulled over and the code reader is showing p303 fault after about 5 mins started the car and limped home in 60, just swap the coil between 2 and 3(2 was Bosh and 3 unbranded ) it has improved but still a slight misfire ,my basic code reader is not picking any codes now but still a slight misfire.
thankyou

audi 1.8tfsi 2010 72000 miles.

yep, youve narrowed it down to the coil. if the code had stayed on cyl 3, youd have a bigger issue, but a quick coilpack change and youre good.

part numbers:
genuine audi: 07k905715g
bosch: 0221604115
ngk: 48042

can get any of those for between £23-£30

anyone else used the new petrol? There are only a few audis not compatible but I’m still wary.
