I am curious if at the same time you got the code your turbo made any kind of unusual whine or whistle sound as accelerate?
Tilal,
In case you have a similar issue, these are the event I've had.
The Turbo has under 70,000 miles on it. He, initially did not change it out - nor try to talk me into a new turbo. He just found a relay related to the turbo that pulled up as bad on his equipment. I don't know which relay and that seemed to be the end of the issue. As I drove away , it went into Limp 5 minutes later. No light came on my dash this time but I had only driven the car 10 minutes at this point as I headed back to the garage. Dunno if the light need more time to appear? Before, with the OLD turbo, a light came on and at one time it went from a orange lighted symbol for ' engine' to briefly " Emission _______" I can't remember the other word or words - just the first word " Emission."
Since the NEW turbo - " Emission " code has never appeared again - even after the Relay was replaced and , again, the New Turbo. To beclear- the car's dash never shows the Orange Engine Light , on the dash - even during 2 Limp Mode events with the new relay and turbo. That's new as I try to crawl onto the interstate with horns blowing off my back bumper. I can't figure that one out unless these warning lights need far more time, like a day , to get their signal to warn me on the dash. Would that me a bad ECM?
I drove the car back to the mechanic with the car running in Limp Mode so he could see what his equipment would find as the fault. If you turn the car off it re-boots out of Limp, for a while. That period it remains out of Limp could be hours.
His equipment still found the new Relay as the fault. His assumption, " Maybe that new Relay is bad. "
He called later and said on further investigation we found the ' Waste Gate" is not working on your old Turbo. I believe just his choice of words on ' Waste Gate' when he really meant to say VNT. As ThunderShorts pointed out - these cars have VNT and not Waste Gates. Not a big deal to me, I assume just the word he wanted to use to try to make me understand. 3 days ago I had no clue what a VNT was.
in the test drive I took with the mechanic, he mentioned there is an upgrade in the Turbo which is nice. I elected for the upgraded Turbo.
My original Turbo he gave back and said all it really needs is a " waste gate" instead of VNT.
Today he said there was excess oil in a tube. I believe he said the Intercooler Tube which was caused by a faulty ceramic seal. I assume that ceramic seal is a cheap seal on the old turbo - so if I resurrect it, I'll be getting a new VNT and Ceramic Seal. To be fair to the mechanic, it was I who was attracted to a faster spooling and increase in power and wanted the up-grade.
My old Turbo ran on Pentosine 5W-40 / 505.05 and I stayed off the gas to keep it's Rev's down as I approached my destination 85% of the time and kept the car running , before shut off, NOT the full 1.5 minutes they wanted to keep the turbo spinning in a flow of oil from the pump. I give it about 1 min to spool down before I turned the key off and starved the Turbo from a flow of oil.
I would say I'm above average in treating the car right. I was a little surprised my old Turbo gave me any trouble at under 70K in mileage.
At this point, the Limp Mode - after - New Turbo and after new Relay and NO orange warning light coming up on the Dash is still a mystery.
