If updated at dealer, when you get home and reinstall the GDE tune, if they changed the code the flash tool will tell you it is different and will not allow the install to take place.

They do not need to touch the engine ecm for the recall, but just in case it is always better to flash back to stock before a dealer visit. If they decide to do a random update on your ecm and the...

The oil type (low ash requirement) on the WK is due to the particulate filter. Ash accumulates in dpf over many miles and ends up clogging the unit as it is not burned off.

P2008 is related to the swirl valves. If you are out of warranty, now would be a good time for an engine tune. Might just save you a $3000 repair bill.

If you can provide a full list of all the fault codes it will be helpful. I do not have any confidence in a rebuilt turbo, unless all he changed was the REA.

What is the fault code you are getting? Is the tuner flashing the engine module or is it connected to the wiring somewhere? Is there a separate controller for the added injection system?
