Just had a fun few hours, was expecting some bloke in an Accord or something to turn up but was a lovely Scottish bloke from the AA.
Doesn't check anything other than the oil, starts it up and doesn't sound like anything to begin with, revs it a little and the noise starts, it was quite irregular in timing and it did sound like it was tappetty at the top end....quite why I thought it was the bottom end I can't explain (must get round to booking that ear syringing at the surgery lol...).
AA man starts proceedings to drop the car off at the nearest Honda dealer which is in Bedford and sort out a hire car for me, then asking if I want to drive there, nursing it, with him following me, so we did that, and to begin with it's not too bad, just the noise. About 3 miles into the journey I get a misfire and the noise gets significantly worse. Pull over and get towed the rest of the way, I've never been in a car being towed before, it's a very bizarre sensation!
Get to the dealer, drop it off, told they're going to look at it tomorrow. Hop back in the AA van and we're off to Luton Airport to pick the hire car up (other places were closed, this was the nearest 24hr one), got myself a lovely Peugeot 308 1.6 sport (not much is sporty about it from what I can tell, nice to enjoy squidgy suspension for once though!) and got home about 15mins ago.
Just the waiting game now where tomorrow I'll hopefully hear from them about what's wrong with it and what's happening next.
