Hope it all goes ok for you
I know how you feel, had my engine fitted back in 2 days ago in my cossie, it was off the road for 3 months having the engine rebuilt & the mot & tax ran out. Drove it straight to mot test place from my mates where the engine was put back in with the bloody ABS light on all the way there

. But when they tested it the ABS light went out

So it passed

, went straight to POffice & got my tax
Iv'e only done 180 miles so far keeping it to 3k max, its well boring,even got burnt off by a Beetle ffs, but you can't do anything about it
Cheers Simon.
