hello ive owned tt,s for years this is our little run about shes 01 fsh \not all by audi/ only when cold the tt starts up fine revs are 1500 but has a 20 sec shutter splutter revs dont drop please help

 

My old 01 180hp FWD used to do this. If I remember correctly, it would either stop if I turned the HVAC completely off while it warmed up or it was something to do with the Air Pump being a PITA. Don't know how helpful this is but sadly it could be a few things.

 

hi huntts vegas thanks for that info im not upto date with the short words when u say HVAC do you mean heater ventalation aic con. turn heater off try that / really stuck when you mention air pump being aPITA could you explain it a bit for me regards tracey thx

 

Sorry about that. Everything seems to be an acronym these days. HVAC - Heating Ventilation/Air Conditioning. PITA - Pain In The @$$.

 

oh right thank u ,c that pump thing can it be taken off and or is it 100% needed .ill get it removed in the mean time and get it checked over thanks tracey

 

air pump is just to heat your catalyst up on start ups, but your cars ecu doesnt get read outs from the o2 sensors for a few minutes because the o2 sensors need to be heated up before working. so i doubt the air pump is the culprit.

Your car also has a self adjusting ignition firing, meaning if you pull one coil out the remaing 3 cylinders keep a 720 - 760 idle. however your engine will rock around do to the unbalanced chain of cumbustion.

vag-com would help tremendously, I would clean or replace your maf, replace coil packs and plugs. btw, tfsi "F" coils are cheaper and better. if you drive it hard though get the adapters. also got a set of STI coils laying around if your interested

 

hi thanks air pump is being removed ,all most out ah ahah my car starts first turn of the key revs about 1500 rpm about 10 to 20 sec later car starts juddering spluttering for 20 sec then returns to normal ,some times i hear that pump coming on but not all the time is this normal only in morning i have this issue thx any more info thx

 

I'd guess your MAF sensor is dirty. Try cleaning it.

Do you see any CEL light?
