HI Guys

I have recently purchased a 2001 octavia TDI 110 and im having some issues with the turbo.

1st and 2nd gear seem to be fine 3rd is tempromental but when in 4th gear at around 3000 rpm the turbo seems to just cut out and only work again once i have turned the ignition off and back on, iv read a few reviews for the 130 Bhp engine and they all seem to have the same issue and solution which is tiny cracks in intercooler pipes and pipes sliding on and off, i havnt checked my pipes yet but is this a common problem on these engines??

very greatful if anyone can help me

also 5th gear seems to be fine, cruises very smoothly,

HI Guys

I have recently purchased a 2001 Octavia TDI 110 and I'm having some issues with the turbo.

1st and 2nd gear seem to be fine 3rd is temperamental but when in 4th gear at around 3000 rpm the turbo seems to just cut out and only work again once I have turned the ignition off and back on, iv read a few reviews for the 130 BHP engine and they all seem to have the same issue and solution which is tiny cracks in inter-cooler pipes and pipes sliding on and off, I haven't checked my pipes yet but is this a common problem on these engines??

very grateful if anyone can help me

also 5th gear seems to be fine, cruises very smoothly,

Sounds like the common VAG problem of the variable position vanes in the turbo sticking if the car has mostly been used at low revs. Engine goes into limp home mode when the boost pressure gets too high at around 3000 rpm. Solution is to take off the turbo and have it cleaned mechanically.

Many threads on the subject on this forum, including one that recommends using a fuel additive at high strength to dissolve the crud and free up the vanes. May be just a temporary fix.

See also http://www.small-engine.co.uk/ for explanation and solution.

A less likely cause is the MAF sensor - use the search for details.

See if you can find someone local with vag-com, and get it scanned. I expect you will see an over-boost fault code being logged.

Mine cut out yesterday when overtaking a lorry with a secondary trailer on the way home from work. bl00dy thing

A dodgy MAF generally means the car drives like a dog all of the time.

Does the guy that was talking about using fuel additive explain how the additive gets through the engine to the exhaust turbine where the problem is without being burnt?
