EGR blanking kit
I have just bought a 2006 Land Rover Freelander Mk1 Td4 with a BMW M47 engine, which has covered 143,000 miles. It is in good overall condition and appears to have been well maintained, although I have no service history. I’m thinking of fitting an EGR valve blanking kit. Would this create as many issues as it fixes? Is there anything I need to be aware of when fitting one?
Would an EDT automotive decontamination be wise or would it disturb deposits that are better left alone?

My first consideration would be that, by blanking off the exhaust gas recirculation (EGR) valve, you will increase the engine's harmful nitrogen oxide emissions.
I understand that many people want to simply remove the EGR valve in order to eliminate a potential problem with the engine, but it is there for a specific purpose and I would be much happier with it fitted and working correctly.
VOSA is in agreement. As of May
2018, MOT rules require the tester to check for modifications to, or removal of, emissions-related devices including DPFS and EGRS, which will result in a fail.
I have not had the benefit of seeing the EDT automotive decontamination unit in operation, so I am unsure of how efficient it is. If it does fully clean the system as advertised, it should help the running of the engine. Having read the technical specifications, the unit uses mineral oil as a cleaning agent.
Another system which uses hydrogen and oxygen to carry out the cleaning process can be found at this link:

I have not tested this system myself, I have heard positive reports about it.
