Audi S5 private sale – worth getting a full inspection before buying?

I've been negotiating with a seller for a 2017 Audi S5 and the price is tempting, but the car has some modifications and the owner admits it's been driven hard occasionally. I'm not too worried about cosmetic stuff, but I've heard the 3.0T engines can have rocker arm issues and the DSG mechatronic unit can fail without warning. Since I'm not a mechanic, I figured I should look into a Trusted Audi Car Inspection Dubai to check compression, scan for hidden fault codes, and inspect the haldex system if it's a Quattro. Has anyone here used an independent inspector for an Audi before? I'm trying to avoid buying someone else's problem, but I also don't want to waste money if the car is actually clean. Would love to know if an inspection helped you negotiate or made you walk away from a bad deal. Any advice on what specific things to ask the inspector to focus on would be great.

Rocker arm issues on the 3.0T can be intermittent at first, sometimes just a tick on cold start before it gets worse, so make sure the inspector actually starts it cold rather than testing it once it's already warmed up. Owner admitting to hard driving occasionally makes this specifically worth flagging to whoever checks it.

Mechatronic unit failures on the DSG genuinely can happen with little warning, worth asking specifically if the inspector can pull adaptation data or fault history through proper software rather than just judging shift quality by feel during a test drive.

Haldex system checks matter a lot if it's Quattro, fluid condition and any stored codes related to the coupling can tell you a lot about how it's been treated. A modified car that's been driven hard occasionally is exactly the kind of thing where you want someone actually pulling that data, not just a visual check.

Compression testing combined with a proper fault code scan is honestly the minimum for something with known rocker arm concerns, a basic OBD read alone won't catch everything especially if someone's cleared codes before a sale. Ask directly if they check for recently cleared codes too.

Had an S5 inspected before buying mine, they caught early rocker arm tick on cold start and some DSG adaptation values that were already drifting from spec. Definitely helped me negotiate the price down given what a mechatronic replacement can cost. Worth every dirham given the admitted hard driving history.
