VW Passat Tdi Sport 130 2002 - Loss of Power - Turbo not kicking in

[Crasher]

Guide? Did I promise to do one?

I know this sounds silly but I had exactly the same symptoms on my PD130 sport 70000 miles and cured it by simply changing the air filter.

'iworld', have you resolved your problem yet? If so what was the fault and the result?

Thanks, MalH

[MALH]

To as36. That's always worth a try. I'll look at mine.

14.30 hrs Just tried removing the air filter. No change.

When you think about it, it doesn't seem logical that simply changing the air filter would solve the intermittant problem. But hey, whatever does the trick (and is so simple) is always worth a try.

I've just left the local *********** picking up some antifreeze.
I checked the price / availablity of the MAP (rear of engine compartment on air duct) and the Thrust Sensor (down near turbo) to cure my limp mode cheaply.
MAP was factory order, Thrust sensor was off the shelf - 5 in stock.
Does one think they have problems with these little devils.........
I'll be trying the latter, as it was the cheaper of the two also.

The MAP sensor and Thrust sensor are the same thing, 038 906 051 C. Do you mean the N75 valve down near the turbo?

anyone know anything about the products made by innotec for cleaning turbos-comes as a 2 stage-second stage to flush out first stage.i would be interested in prices and any possible long term effects this product may have?

Hi Crasher,

The little device fitted in the inlet ducting from the intercooler > manfold has the p/n 038 906 051C on it - held in by 2 torx screws, the parts guy called it the convertor? Is This the MAP?

On an earlier thread the thrust sensor p/n 1J0 906 627A was mentioned as a likely cause of turbo limp disease. This is the part they had 5 in stock, I asked to see one so I could find it in the engineroom. Is this the N75 valve?

As you say, its tucked up near the turbocharger and has a pressure accumulator next to it. Looks like I will have to both break & dislocate my wrists to fit it...

I asked about a diagnostic check, £47 inc vat which is reasonable for a ***********.

PS great footer to your user ID - love to moggy too...

038 906 051 C is the Thrust sensor but is actually a combined MAP (Manifold Absolute Pressure) and IAT (Inlet Air Temperature) sensor.

1J0 906 627 A is described as a “Pressure Converter” but is more often referred to as the N75 valve.

Please don’t use that expression “********hip”, it isn’t necessary.

Sorry Crasher,

Thanks for the info on the switches.

ALL modern car dealerships are a rip off. It is common knowlege that new car sales margins are miniscule. The only way they make money is on service and parts - hence the expresion. How come Euro, Andrew Page and others sell all the same none captive parts - even the same manufacturer at up to50% less.

If they dummed down the new car sales area, got rid of 50% of the metal thats taking root on the forecourt off their books, the service cost MIGHT be somewhat lower.

Sadly the motor industry's only interest is in moving metal, pity they can't focus a modicum of interest or consideration on customers with problems ie water from pollen filters wrecking CCM's.
