EGR delete

[Brammers69]

My engine management light comes on and the code reader tool says egr problem, I've messaged a few garages that do cleaning and engine carbon cleaning etc etc and the common reply is egr software delete and remap, does anyone have any advice on this situation? My car runs fine with no obvious restrictions even after the light comes on, it's the 3.0tdi on 124k

Under MOT rules MOT testers can only check the parts are fitted, not if they've been blanked out of the ECU. Garages are suggesting this as it's far cheaper than changing the egr.
