I have no idea about car mechanics, other than changing filters and bulbs and the like, so wondering if someone might give me some advice as to whether a 1.9TDi Octavia 2009 can run with the turbo disconnected?

 

Reason being is for the past several months the car has been spitting and farting when you go to give it more power in higher gears, and it seems to do this when the revs are around the 15-20 mark. It's quite sporadic when it happens, sometimes only jumps a little, other times it's all the time and can be quite violent! And only when the engine is hot.

 

I've had the back fuel pump changed, the high injector fuel pump changed (as there was oil getting into the fuel), the ECU unit was changed beginning of the year as it had shorted out.

 

The fitter at the garage says it could be the turbo as he's had that and some other component, think it was an ECJ unit, could be wrong like, but apparently it tells the ECU how much air the turbo is getting, so he's had those two things off and checked them, says the push rod for the turbo valve was starting to wear :/ and also the turbo, not buggered but was on it's way out.

 

£435 for a new turbo, which the fiter said may or may not fix the issue. So I thought.... if it was the turbo, could the car be ran without the turbo fitted to see if the car did it's little tricks of spitting and farting? If it didn't then we know it's the turbo and it would save me having to fork out more money to keep this car running instead of just going and getting a new bugger.

 

Any advice would be appreciated. I'm a novice so reply in laymans terms

 

 

I wouldn't even try to run the car without the turbo.  The ECU is expecting it to be there and will only cause you more problems and make diagnosis of your actual problem more difficult.

 

Here is what I would do

1. Take it to a different mechanic - one who specialises in the VAG range.

2. Have it scanned with VCDS.

 

Report back if the fault persists and the new mechanic cannot sort it out for you.

I agree with radders567.  The PDs were never designed to run without the turbo.  If you tried it, I think you would find the lack of power very 'interesting'.
