Hi I’ve been told by my garage that he can’t get into diagnostics as it’s locked Why is this done as I think this is illegal and how do I get it unlocked

I got a weird one. I'm fairly car literate and I'm usually able diagnose and know the problem to pull in to my local independent shop and tell them this and this need to be fixed and replaced. But this has me stumped. I have a 2016 Q5 2.0 engine that went bad with carbon deposits yada yada... So I stepped up got a new motor from Power Engines it came all crated up they were super helpful pleased with them. My mechanic moved all the bits and reattached them to the new engine from the old.

Although not required as yet, I'm thinking /looking ahead and wondering about servicing costs. Like all Audi dealers/dealerships it's best I guess to have your car serviced by Audi but I'm sure the price/s will not be as cheap as independents? (Yes they would have to use genuine parts). Does this forum show recommended companies i.e good garages that will be cheaper but carry out as good work as Audi. I look forward to guidance. Thank you.

Good day all, I have a 2.0 TFSI with the ZF 8 speed auto ‘box which I intend to get serviced within the next couple of months. Is this just an oil and sump/filter change or is there mechatronic seal (for the wiring) on these? I’m going to get the oil changed in both diffs and the transfer ‘box, is there anything else within the drive train that needs looking at while it’s on the ramp? Mileage is 65,000 miles.

Hi, I’ve recently got a second hand A1 2012 S-Line 3dr. I took it to Halfords and they have advised I have a blocked Air con. I’ve just replaced the the air filter and cabin filter as they were past due. Does anyone know if I can unblock the A/C myself and if so how to do it and what I’m looking for. Many thanks in advance
