2001 Volkswagen Beetle, turbo diesel, slow acceleration

Hi Jay, What do you need to clean and why? If the intake is fouled with oil it would seem to me that the turbo has become defective and is leaking oil into the manifold. Let us know what the problem is and if you want to clean the outside or the inside of the ducting and manifold? there is a great big difference. Regards John

Try using sea foam it's a product you can get at a napa or advance auto parts store. They will tell you how to use it

ok first off what engine does it have 1.8 turbo,1.9 turbo diesel, 2.0 gas......there are several things to check : mass air flow sensor, oxy sensors B1 S1 and B1 S2 , a bad throttle angle sensor will do this too..give me this info and i can help you better..

It can have a 1.8 turbo gas engine, a 1.9 Diesel engine, or a 2.0 gas engine.

WELL BOTH TRANSMISSIONS IS 6 SPEED TRANSMISSION USED ON TURBO GAS AND TURBO DIESEL ENGINES.HFZ AND GHE TRANSMISSION CODE.1.9

I personally have used shell rotella 5w40 and nothing else since 2001. You can find it at almost any wal-mart, and napa can get it for you. Recommended viscosity is 5w40, with a commercial rating (ch, ci, cj...) and turbo approved.

Check and replace air filter and fuel filter with a additive,I sugest LUCAS FUEL ADDITIVE AND HEET IN THE RED BOTTLE.

change the stalk unit on the steering column

it is but if your check engine light is on there is some vaacium hoses than get crak and old make sure they are ok
but vacium leaks are more easy to find when ideling not under aceleration
