TDi 130 Turbo Trouble when chipped
Discussion
Top of my wish list at the moment is chipping my Golf 130 TDi.
One of the tuners I was talking to reckoned that some Golf 130s' blew their turbo when chipped/remapped.
Never Audi/Skoda/Seat 130 motors, just the Golf (Surely they're all the same?).
He reckoned my late model (53 plate) would be unlikely to be affected.
Anybody confirm or deny this?

The 130PD engine is the same throughout all the VAG range with just ancillary parts changing between models and marques.
Mine has been serially reprogrammed to a supposed 163Hp for over 13,000 miles now and has been totally trouble free. I suppose it also depeneds on whether you go for a generic chip or a custom one.
A custom one will take into account any other engine mods you have done which could all add together and push the turbo a bit too far.
The generic chips alter the fuel mapping but my tuner said that all it does in essence is widen the windows to which the turbo will operate and to what boost level. The VAG safeguard limits are not changed at all so as long as you keep to the 10K service interval you won't have any problems.
Regular oil changes = happy turbo

Cheers for the replies guys.
I was talking to Star Performance in Fife. In no way am I criticising the guy. I'm just suprised I'd never heard of potential turbo trouble on the 130 motors so I thought it fair to look into it a little further and ask around.
Certainly I was not put off the idea of chipping the car and may well go with Star.

depends what is causing failure - is the turbo stalling?
The calibration will differ between cars in different inertia classes, and calibration 'feel' will be different between the brands.
The Turbo in a 130PD hits peak torque at 1900rpm. Up until that threshold is reached the vanes are contracted to funnel all exhaust gasses through as tight a hole as possible (Hence faster turbine speed).
No chip can change that.
It's only after this magical rpm that the vanes start to open up to regulate the boost pressure. Here is where chipping can alter when/how far they open therby giving more boost over a wider range than normal.
I've never heard of a turbo diesel turbo stalling. Petrol yes but diesel no.

The variable geometry of the turbo might be under ECU control as well, I would have thought?

Neither have I, just speculating!
DOn't know what the pressure ratio of a typical diesel turbo compressor is.
