Turbo issue

[Adenuf]

Driving along normally, and twice on Friday, I felt a very light 'nudge' through the drive train, and the turbo ceased to function, putting me into 'SDI' mode.

No pops, whistles bangs hissing or smoke

 

 

Turn off, re-start, and all well again..

Clearly this is going to continue, so what should I be checking out?

 

05 reg vRS, with 145,000 unabused miles, and FULL service history.

 

It WILL be fixed, regardless

On what basis do you declare that?

 

Did it happen during the warm up period?

 

Your first thing to do is to have a VCDS or similar scan for fault codes, my guess you will have overboost ones and the variable vane turbo needs a Mr Muscle enema.

In my experience, once something starts going wrong intermitantly , it's a sign of bigger problems looming.

Gut feeling.

 

First happened 3 weeks ago, but all fine until Friday cruising at 50

 

Engine was full operational normal temp.

 

I'll get it scanned this week. Can't complain really, as it's been an absolutely fantastic car with virtually zero issues in 18 years
