Well, after replacing suction control valves, rear suspension control arms, in the last few months, I had the turbo fail big time on Monday (approx 110k miles FVSH with synthetic oil). On accelerating, engine coughed, puffed out some black smoke and then gave a whirring noise from the left underbonnet area. No light came on and I managed to drive the 1 mile home. Started the next day and whirring noise still there. Drove out and up a slight hill and then noticed a WW3! white/grey smoke screen from behind. The engine lost power but still no light. Eek! switched off and got a friend to trailer it back home.
Removed rubber hose to turbo to check for play in the shaft as advised by specialist - the whole impeller/shaft is completely loose and waggling around!
Local Opel dealer has quoted 3200 euros (~£2800) to replace the turbo, gaskets, and program the "Calculateur" which I assume is use of Tech 2.
I'm not prepared to pay that so will get a new turbo for around £700 and attempt to fit myself with the help of a couple of knowledgable friends.
Anyone have any advice on how to remove and replace a vectra 3.0 v6 diesel turbo, anything special to watch out for? I don't really want to start the engine again before replacing but do want to replace the oil and filter. Will it be ok to do this cold? I also read another post on here (GSi I think) that talked of the need to prime the new turbo and clean the banjo filter but I don't know if this applies to the 3.0L. Also would it need to be Tech 2ed or calibrated in any way?
This car is fast becoming the best and WORST car I have ever owned.
