Ask anything — a torque value, a diagnosis, a procedure, a known fault — and get a straight, accurate answer with no forum guesswork and no "consult your manual." It is the manual — and what it doesn't cover yet, it researches for you.
Every answer is an original, house-written reference. We review and synthesize the best of every relevant source — factory manuals, official data and hard-won owner knowledge — into a single, quality-checked article, cross-checking the facts and resolving conflicts to the factory figures. Ask something we don't cover and we research it, then email you the finished write-up.
Mk1 through Mk8 — the 8-valve and 16-valve fours, the VR6, the 1.8T, and the 2.0 FSI/TSI EA888 — engine specs, known faults, procedures and recalls, generation by generation.
Factory tightening torques from the Bentley manuals and VW/ELSAWIN tables — head bolts, cam and timing, suspension, driveline, brakes, body and climate. Source conflicts resolved to the factory figures.
Hit a gap in the reference and MrGTI doesn't guess — it flags your question, our team researches it properly, and you get the finished, verified answer by email, added straight back into your thread. Every question makes the reference sharper for the next owner.

Grounded in how GTIs actually break and get fixed — timing-chain tensioners, water pumps, carbon build-up, DSG mechatronics, coil packs — owner-reported faults alongside the factory data. Add your own notes to any thread.
