took  my car in for check up. £165 diagnostic later i was told it needed a new turbo, that oil was found in the inlet manifold and that as a result i also needed a new gear box sump. im a tyre kicker so none of this makes any sense to me so im looking for some advise. i bought the car 20 months ago as an approved bmw including 1 year warranty. i have had various issues with it and it has been back to bmw numerous times within the warranty period. some of the issues were resolved, but several were not, including the vehicle holding its gears too long and running rough. Bmw said that they couldnt find any fault in this respect. the warranty has since expired and now 8 months later i am facing a colosal repair bill in ecess of £5000 for items that i suspect were faulty and that should have been sorted within the warranty period. my question is with 86k on the clock should the turbo be going and could sticky gear changes and rough running be a symptom of a potential turbo problem? its an e70 3litre diesel auto.
any ideas?

Get a second opinion!

Turbo failure can occur at anytime unfortunately, and 86k miles is not an unknown failure mileage on any turbo powered car.  Why would you need a new gearbox sump?  Has it had an impact with something?

The rough running could be a turbo issue, but the gear shift is nothing to do with it or the sump as that's just sheet metal.  Do they mean the 'Mechatronics Unit'?  That is the gearbox brain and is at the bottom, but that's gearbox not engine and not connected to the turbo!  Something doesn't sound right at all.

You could get the whole lot done by an indie rather than BMW, and for a lot less money.  BMW Dealers have a 'replace' rather than 'fix/repair' ethos as BMW themselves don't allow them to do a lot of repairs and it means they can get bits back, evaluate them and get them refurbed to sell back at inflated prices.

Requested written report from diagnosis. Will get 2nd opinion from an indie as you suggest.

Note

Oil in the inlet manifold could be attributed to the EGR (Exhaust Gas Recirculation)
My inlet manifold is filthy, and you can trace the grime from the EGR through..
Prior to the EGR Connection is as clean as you'd expect...

Just because stealers supply the cars does not mean they know how to fix them...
Get a decent Indy to look into it.

I got a 2nd opinion from an independent garage and they did full diagnosis for free. Don't need a new turbo it's fine.New glow plugs and a full service should sort it. Many thanks for your advice. My advice to anyone reading this is never take your car to Cooper BMW for service or repairs. They are border line incompetent and ridiculously over priced. They charged me £165 to wrongly diagnose my fault and also fractured my locking nut and didn't tell me. They are real cowboys.

Ask for a refund.......

I had a Dealer do this to me about 6 years ago and I refused to pay the £500 'diagnostics' bill. 

They blamed the tracking device for causing a battery discharge.  It wasn't, they wrecked the tracker, and eventually replaced the starter under warranty!

I understand your frustration!  It's not just BMW, but I think modern cars are way beyond the abilities of 'technicians' as they are now call, to fix them.  If the computer doesn't give them the answer then they cannot work from 1st principles to sort it without £500k of kit.

That's good news.

Just be cautious ref the glow plugs.
They are not the strongest, and usually are a pain to get out, if they come out!!!
There are some who have had them break and need to be drilled out...

Doesn't mean yours will do that, but just bear it in mind, and treat accordingly.

I have one glow plug open circuit, but am not bothering with changing it until either a few more go, or i get trouble starting it..
If it was going to play up, it would have done it by now what with all this nice weather we've been having
(and it would happen to me.......)

+1 On Cooper BMW.

Completely incompetent.

How these people are still in business is beyond me.

Which Indie did you use?

I see this sort of thing every day
By the dealers

It's normal to find some oil in the intake on diesels engines if you don't give them some stick from time to time
All that driving in traffic does not help
Also check the breathers

As for the gear box sump check the multi connector tube seal for leaks
