So last Sunday 29th May, fellow member Jack P & I completed the London to Brighton run covering 450 or so miles from my home and back again.
We started at Brooklands museum and ended on Madeira Drive Brighton. Jack and I went down on the Saturday to have a look around the Brooklands museum and Mercedes Benz world.
Big thank you to Jack Phillips for his fantastic navigating skills. Has such a great day visiting museums along the way and meeting Mike Brewer.
We'll do it again next year but next time Jack will be driving his TT and I'll be navigating!
I agree with Gareth. Gone off fuel won't help it's running. An oil change is advisable too.
Best way to determine its power is by Dyno it on a rolling road.
18" wheels are possible as even 17" alloys were fitted to certain models:

I'd recommend a diagnostic check to see what fault codes flag up. It could be the fuel pump, MAF sensor (would run rough before cutting out though), cam sensor, lambda sensor.
Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂
It'll have to go to a dealer or an retrofitter like autologics could do it. But expect to pay £600.
