So eventually got round to getting an exhaust - went with Milltek as it was a pretty decent price and I do like the sound of it.
To be honest, considering how rusty it was, it came off a doddle!
Although, that isn’t the end of the jobs - I have developed a rattle upon startup so I have bought all of the gear to change the timing chain and tensioner (even though I did check blocks 91 and 93 and it looked OK from what I’ve read)
I got a P0011 code and it cleared for a bit but has come back - the car is due a service also so going to do that as well as a DSG oil and filter change - busy day tomorrow!
