Hi all,

Hoping someone can advise on this one 'cos its doing my head in!

Had my new octy vRS petrol for about 5 weeks/2500 miles now and love it :clap: , however I've noticed that there is a hesitation when I put my foot on the throttle at low revs. It doesn't feel like turbo lag as there is literally no acceleration at all. Its most noticable in second gear when rolling up to roundabouts and junctions (the kind of time you really don't want hesitation!). Today it really wound me up as I stalled twice in a multi storey - I let the revs drop to about 900rpm (in 1st gear) whilst coming to the top of the ramp, then went to accelerate when I could see it was clear. Instead of it instantly picking up, the revs continued to fall and the engine stalled.

Is this hesitation normal? Is it something to do with it being a turbo? Any help would be greatly appreciated!

Cheers

Pat

sounds to me like you are driving it as you would a N/A engined car. the boost doesnt kick in until about 2k, so what you are feeling is in fact turbo lag. its not good for the engine to drive it like that. if your pulling away id say you need more than 900 revs, maybe 1250-1500 revs, especially on a ramp.

Is this your first turbod car??

In a way it is worse with a DSG, admittedly it doesn't stall but when you are trying to pull out gently at a roundabout with what appears to be plenty of time then the engine does a disappearing trick. So you adjust by pushing your foot down and the electronics takes over (think Judgement day) . . . the DSG drops into first gear, the turbo has had time to spool up anyway so before you know it you are at 5000 revs and you are off across the roundabout like a scolded cat . . .

If you had a diesel rather than a TSI there would definitely be something wrong. A 2 litre petrol engine, turbo or not, should have some pull at those revs though it'll be a lot happier at 1200+ rpm.

Sure is, but driven my mates WRX before (though not very slowly!)

Must admit I've tried dropping a cog to beat the hesitation then found myself nearly rear ending the car in front! Lucky the brakes are strong!

Thats exactly what I thought - at low revs I thought it would feel like a 1.4 but still pull immediately.
