Sounds easy, I'm guessing I can just put the original value back in to get it back? Will have to sit down with VCDS when I have a few minutes alone and go for a test drive without kids in the car.

Meanwhile, I think you might appreciate this:



The lack of power did not stop me from towing my little 42" lawn tractor from where I live in Flamborough to nearby Haldiman County. Its about 60 km or 40 miles one way with the steepest uphill section being Highway 403 between Aberdeen Ave and the Lincoln Alexander Parkway in Hamilton, Ontario where the elevation changes only a few hundred feet in a few miles up the Niagara Escarpment (locals call it the Hamilton Mountain). There I only managed 80km/h in the 100km/h zone, which is faster than some trucks manage in the same area, so I turned my hazard lights on and kept my foot to the floor in fourth gear.

I was pleasantly surprised that there was no smoke and the temperature reported by the Scanguage only climbed from 82 degC to 85 degC - barely operating temperature. I was having an overheating problem on long uphills before the turbo blew, I'm guessing the thermostat is not opening fully, I guess I don't have to worry about that for a while. Also, I was getting clutch slip in 5th gear at lower rpms on steep hills. It only happened around 2200 rpm and it would instantly remind you that you should be in a lower gear, dummy. Anyway, I don't need to worry about that anymore either!

Less power, less problems!

The more I drive the car the more confidence I get.

I wanna see more fuel economy numbers...

Maybe we can take up a collection to buy you a used turbo?

EDIT - did you ever get your timing belt done again?

I have a B4 TDI intake manifold and was thinking of drilling and tapping it for the pressure gauge I'm going to install then swapping it with mine until I realized the inlet points toward the driver's side fender, not the passenger's.
One of those would neaten your intake plumbing up considerably.

It might, but then I might have to re-do the crank case vent plumbing. This works, especially with all of the EGR and air conditioning stuff out of the way.

Fuel economy numbers are coming... I've done 400 more km this tank already.

You got me: no, I haven't done the belt yet. I'm pushing 200,000 on this timing belt. I'm afraid the cam and lifters are close to wearing out, along with the injection pump, power steering, you name it. Its been fun but I don't plan on putting another timing belt on the car, let alone a turbo... Its all about how much time I have to work on the car and whether it is still fun to repair, and fun to drive. To me, "fun to drive" includes puttering along making weird engine sounds and getting ridiculous fuel economy.

Part of me hoped the car was dead when the turbo blew, so that I could move on to a different project....

...but then I was, and am daily, pleased to have it running again without spending any money.

I should probably do the timing belt before replacing the turbo, right? Either way I've decided to wait till the 600,000 km milestone before I do anything.

EDIT: Besides! Imagine I had done the timing belt, and that engine bracket that is stripped out, and the cam and lifters at 560,000 km - and then the turbo blew at 597,000 I would be like, "Oh man I wasted like $1000 (Canadian) and an entire month worth of my free time unless I go and spend more money and time, ARG!!!" Whereas, not having spent any of that time or money I can be like, "Yeah, turbo blew, whatever, didn't need it anyway."

I tapped my intake for a gauge.
I drilled on top of it over the runner to cylinder 4.
For a few months the gauge buzzed every time I took off and was quiet cruising.
I think its was getting pulses from the air flow to the cylinder.
If I take it off again I plan to drill it closer to the EGR valve.
I also found the hard plastic tubing that came with the gauge gets hard with time and becomes brittle.
Have to come up with a better softer tubing that's heat resistant.
I'm thinking about silicone if it can hold 30 LB.
I also found the hole in the fitting in the manifold gets covered with soot and that seemed to dampen the pulsing and stopped the buzzing.
