Turbo removal mk8 2.2 RWD Euro 6

[jack26]

Trying to remove the turbo on my 2.2 2016 RWD Euro 6 but cannot release the one nut and two bolts that fix the SCR to the turbo.

Wondered if anyone had done this and had any tips?

One train of thought is to disconnect the SCR from DPF and then try and remove the turbo with the SCR and split them when removed. Only issue is unsure if it could all be pulled out in one?

Depending on what your end goal is, it's easier to take out the 5x M6 bolts around the exhaust snail and leave the exhaust all connected.

You can swap the core or clean and free up the vanes etc.
Just be careful of the spring seal between the two halves of the exhaust snail.
One bolt near the bottom can be a twat to get back in but doable.

It'll also let you get to the manifold bolts if changing the full thing.

Thanks for reply.

Finally managed to get it out and it probably might have been easier to remove it with the exhaust manifold. The only reason I did not go that route was the bolts looked well and truly rusted in and the 3 rear ones for EGR were a pain to get at.

In the end the two bolts that locate exhaust to turbo sheared off but the nut on stud came off. One nut underneath where turbo is bolted to manifold came off but was very tight. The top nut started to round off because I used a standard spline type spanner, should only have used a Hex type. The nut on the other stud underneath was difficult to access so ended up damaging that nut due to socket being at an angle. So supported engine on engine hoist, removed engine mount, OS headlight, airfilter housing and washer filler neck. Access was much easier now and should have done this at the start. Anyway using a dremel carefully cut some of the damaged nuts flange away, left overnight with more WD40 then managed to get nut off next day using a 13mm extractor socket. Inspecting the old turbo showed that the variable vanes were sticking and movement of the linkage felt very 'notchy' with it grating and getting stuck occasionally as the linkage was moved. So at least confimed the issue. Not impressed for a 43280 mile vehicle but perhaps underuse is the reason?

Update on this for anyone undertaking similar task.

Final issue is trying to reset the turbo learned values which at the moment has not been done. Initially tried using my Launch which shows the various live data from the turbo actuator but could not reset it or manually control the variable vane. Next tried ForScan and got exactly the same result. So as a sanity check removed the actuator from the old turbo and plugged that in to double check that it wa snot an issue with the new turbo. Results were the same and as the ignition was cycled the actuator arm moved between its limits and then settled into a given postion, which according to its angle was similar to the new turbo. Reconnected the turbo and then wondered if the Euro 6 2.2 engine did a 'full and free' sweep of its actuator at key on as a check but also set its limits for calibration hence not needing learned values to be cleared? Finally decided to double check using Ford ETIS and the VCMII that I have which was last used about 2 years ago. Did not realise that Ford had moved away from the PC/Laptop license method to individual account so I had to update FDRS, IDS and the VCI driver. Paid my 1 hour access and then tried to connect with the VCMII which failed because it now needed a firmware update which kept failing. Using the Launch smartlink 2.0 VCI on J2534 got the FDRS to work fine and FJDS but they do not offer ablity to reset the turbo so not a lot of use. IDS does not work with J2534 needing a VCMII or VCM3 so stuck!

Does anyone know if the turbo on the Euro 6 2.2 2016 need the turbolearned values resetting and if so what diagnostic tool hs been used?

perhaps you will have to pay licence on forscan to get the extra features.

have you tried disconnecting the battery , batteries for 20 mins

all the best.mark

Yes I have the full licensed paid version of ForScan but no luck.

Managed to get the Ford VCM2 to work this afternoon and paid for 1 hour on Ford site for IDS access. Interestingly (or not) tried to carry out the turbo learned values reset using IDS and got the same result with 'failed'. So thats thre different diagnostics giving same result.

The only one that gave some kind of message was ForScan confriming that 'Vehicl conditions Incorrect'. I am going to email the ForScan support and ask if they have any data on this message.

Obvious things that have been done are battery support, engine cold and then tried engine hot, both cases ign on eng off, no DTC's. Out of ideas now but the van drives fine.

Update on the turbo change and resetting.

As mentioned previously I could not reset the learned values for the Turbo or operate it through ForScan, which is the licenced version. Also tried with my Launch diagnostic and Ford IDS whilst logged into their factory with same results.

Then tried to clear the learned values from EGR valve as a 'check' and got the same result.

So reset the throttle learn using Launch and assumed that the EGR and Turbo must learn their values on the Euro 6 2.2 Duratorque. This was noted in the Garrett turbo instructions that some vehicles will relearn without clearing existing values.

Just come back from a few weeks in Scotland clocking up over 1300 miles without any issues and engine a lot more flexible pulling the 4.3 ton weight a lot easier.

Thought I would complete this post as it might be useful to someone in the future.
