There are the ones who are driving the requirement for a EU wide 'MOT' type test which will include a way a checking for engine management units that have been modified since manufacturer.
Shame really. Doesn't that sound like the beginnings of "if you don't get it from dealer it's illegal"? To put that in perspective my battery has had it. Dealer wants £116 + £72 fitting for a new one. My local Audi indie will fit the genuine battery for £98. Why is the labour £72?! To pay for my "free" coffee.
