Hi,

I've had my TT for 2 years now and in the last 6 months or so my car has started to lose acceleration until i take my foot off the accelerator and put it back on again. All the electrics will still work.

It happens intermittently in all gears whilst going on straight roads up hill and could go for weeks not happening and then happen constantly?

Can anyone help me with what it could be and if it is expensive to fix??

Thanks

 

interesting...i'll be following this one for sure.

 

I had the same problem. It was a bad mass air flow sensor.
