| How long to fit a new turbo? |
|
My patience is wearing very thin. The vehicle (2012 D4) went into the Indy's 9am Tuesday to remove knackered secondary turbo and fit new. Body off etc. Yep, I accept that after all I'm a long time customer and you've never let me down.
It's almost 3pm Friday and still no call. I get wound up with not being kept informed. So, my question is, 'How long to fit a new turbo?' I'm pretty certain it ain't almost four days!

The body off is no small job and the speed of accomplishment depends on how often the mechanics have done it before. And, assuming no bolts or other fasteners break which is asking a lot!! The Turbo itself is a small enough job, but there can be issues which slow progress such as seized exh bolts etc.
That said, I fully sympathise with your frustration as Garages are woeful at communicating with customers, unless its to look for money! By the way, did you consider doing the rear timing belt while the body is off? If it hasn't been done, now's your chance as its a quick job with access unhindered.

I presume you are doing lots of other work as the body is off?
See this thread:- https://www.disco3.co.uk/forum/chassis-sus...65489.html
My notes (for a D3) which I never had to do:-
Brake pipes
Front + rear upper arms
Cambelts
Silicone hoses/big intercooler
Turbo actuator rod
Autobox filter
Clean in-tank pump gauze
Carefully inspect the wiring for damage, and repair if required
Check rear air conditioning pipes
Check EGRs & turbo & turbo pipes
Check High Pressure Fuel Pump
Front & Rear Belts
Possibly
New Water Pump
Antifreeze
New Auxiliary Belt
New Auxiliary Belt Tensioner
In addition to all belts (front & rear) replace both idler pulleys, bolts & tensioner & bolts.
Consider replacing oil pump assembly & bolts - 3 hours extra labour when doing all belts etc.
Consider replacing water pump - flush & replace coolant.
Consider changing intercooler hoses, particularly the 2 small ones for silicone.
Consider replacing and possibly upgrading intercooler. At very least clean intercooler & radiator.
If manual consider fitting new clutch (& flywheel) - 1 hours labour as opposed to 6 to 8 hours.
Replace rear brake lines
Check anti-roll bar bushes & shims -
takes around 60 seconds with the body off.
Check cross-over pipe at rear of the engine
Wash chassis & underside of body, rub down and underseal any rust reapply Waxoil where necessary.
Remove the turbo, fit new modified actuator rod. Take out the studs and drill the threads out to 8mm. Use 2x M8 flange bolts to refit. This aids future turbo removal massively, and is also much quicker.
Check all suspension bushes & shims.
It would be an excellent idea if someone, with more skill than I, were to take the above & edit it for both D3 & D4 & post in the wiki.
