Crap first start

(1/5) > >>

So.... battery brand new, so its not the battery.

The first start of the day is usually crap.... sounds bad, and seems to only just kick into life....

Once started the car runs fine

Any clues?

Mine will do that if you let go off the starter as soon as the first 'fire'

If you hold the key until its 100% started then it's fine.

My battery is old which won't help, but as long as i hold the starter on until it's 100% started/as soon as it idles nicely - then its fine

Apparently its not uncommon for the TFSI's to stumble into life a bit, I read some bits on a TT forum saying their starts were a bit unconvincing sometimes.

If it's a cold morning or the cars been still for a while I sometimes turn on the ignition for 5 seconds (let the pump prime) then turn it off (keep the key in) then turn it back on, wait 5 seconds and start the engine. Or at least just wait 5 seconds after turning the ignition on once and that seems to help.

Mine will struggle a bit on a cold morning but I don't worry about it, the fuel pump on this engine primes when the drivers door is opened I think.

leon does the same too, so I changed battery and coilpacks and plugs,

app its a tfsi thing, even says it in the manual too
