Rest turbo replacement 35i

Post by Nick9one1 » Thu Dec 28, 2017 12:53 am

How difficult is the rear turbo to replace? My 35i has quite a rattle. Any tips/tricks?
Most of the guides look like they're for the 335i, but e89 engine bay is a bit tighter.
Had a quote for about £450 from a specialist in Nottingham.

If you can get it done for £450 then let them do it..

Bumhole of a job and in reality it's engine removal to replace correctly

It's done 85K

I've found a pair of refurbished turbos for £440, or alternatively a flapper repair kit is ~£50.

I've booked the car in at PMP cars Nuneaton.
It looks like they specialise in wastegate repairs.
£590 all in.

In case anyone else is interested - I had a great experience at PMP.

Couldn't get there until after it closed, but the owner said it wasn't a problem and met me about 7pm.
Dropped off on the Weds and collected mid-day Friday.
Car is perfect now, no waste gate rattle at all.

Cost was £590 all in
They also do walnut blasting for £250

Why would you want your 'walnut' blasted? (And what is it, anyway?)

google is your friend :p
Walnut shell blasting is an effective method for cleaning the engine intake of your car without damaging the intake valve, valve guide, or intake port.

Direct injection engines like the N54 tend to build up crud around the inlets as they dont have fuel vapours running through/over them.

I think walnut is used because its quite hard but softer than metal.
