A3 2.0 TDI TICK OVER

[MARTYNH]

Hello  i am new to this ,

I have a 2007 2.0 tdi  170 bhp quatro  have had this car from 3 months old no problems at all until the last 6 weeks 

the tick over goes from 800 to 1000 rpm , the car seems to be hesitant before it happens and i think when i shut the engine off 9 out of 10 it seems to clear it until the next time ?

Once it has cleared it's back to the old car . 

I hope someone can help ?

Hi Martyn...welcome to the Forum

I would imagine it just needs a clear out.

Would advise running a cleaning additive through the engine and use each time you fuel up until it clears itself...generally works a treat.

Let us know how you get on with it

Hi Trevor.... thanks

i have used a cat clean is that the same thing .

do you think it's a dirty fuel problem ? 

[Trevor]

Unlikely to be dirty fuel but I would advise putting quality fuel (BP, Esso, Shell) into the tank for a period as not a lot more expensive than the supermarket fuel at the moment

The cleaning additive I would use is either the Halfords own (which works surprisingly well) or something like Wynns or STP where you just add it to the fuel to clean injectors, EGR, etc.

Cheers will give it a go. 

Is Forte any good as a local motor factor sells it which is 2 minute from where i work .

[Trevor]

Yes Forte are very good...give it a try

[MARTYNH]
