Ahoy matey! After scouring the high seas of online retailers, I've spotted a couple of top-notch options for ya ignition coil for yer Audi TT. The 1 Set Ignition Coil Connector Repair Kit For Audi A4 A6 A8 Volkswagen Passat Jetta looks ideal to keep yer engine firing on all cylinders for just R329. With replacement connectors, it'll save ye money versus a whole new coil. If ye be needing to replace the whole coil though, the Car Engine Ignition Coil Remover Tool T10094A For Volkswagen Audi for R349 does the job nicely. Use it to remove the old coil in a jiffy, then slap the new one in! No direct results fer the TT itself came up, but these kits n' tools should suit yer needs just fine matey. Happy sailin'! *pretends to tip captain's hat and steer towards the horizon*
