I recently bought a 2002 golf 1.9 tdi with 100bhp and I am having aceleration problems where when I accelerate from 1st gear and so on its a struggle and it starts to stammer,and as a result I'm losing...

Try the easy stuff first, use a fuel additive, such as" power service",it will displace any water that might be in the fuel system, as well as help clean the injectors, not a bad idea to use it all the time. If You don't know when the fuel filter was last replaced, or if it was l long time ago, it's probably time. If neither of these work, it's time to have the injectors checked as well as fuel pump pressure checked. Good luck. Jim
