Help on Turbo

8 posts in this topic

I have not used my 2005 Smart for Two Diesel car due to medical reasons.

I started it up with no problem but when to the store and the Turbo does not cut in

 

What do I do Now??

 

Thanks

Take your Smart to a competent mechanic to get it checked over.

How do you know that your turbo isn't working?

 

Are you in limp mode from a stuck EGR valve or more likely partial limp mode from a stuck wastegate?

won't go over 3000rpm, when turbo works then I got my full rpm.

you have that backwards ... cart before the horse ... so to speak

you need to do a lot more reading on this BIG subject.

 

The ECU has the car in 'limp mode', and that prevents the engine from going over 3000+/- rpm

 

The engine will rev well above 3000 without a functioning turbo, as long as the ECU does not have it in 'limp mode', and there is not a lot of load on the engine (hill/speed)

It would be worthwhile getting an OBDII reader to determine the code of the fault.

 

It is highly unlikely that there is anything wrong with your turbo.

 

The most likely suspects are a stuck EGR valve or stuck wastegate or both. I have had both on one of my 2005 Cabriolets.

 

The wastegate can be freed by removing the rear body panels and lubricating the wastegate arm.

 

The EGR valve can be cleaned and/or replaced with an emulator.
