almost as soon as i deal with the air sensor up pops another fault (to be fair I have seen it before, but cleared and ignored it)

apparently 3 are normal gloplugs and one is special (normally cylinder 3) which an an additional sensor and is much more expensive
Luckily this is cylinder 4
Should really change as a set, but this time Im going to wing it.
2 parts I needed to buy
- New Bosch gloplug (ECP partno 438 44 0017) from EuroCarParts : £14.99 inc VAT
- Draper 16579 Metric 3/8-Inch Square Drive Hi-Torq 6-Point Deep 10 mm Socket https://www.amazon.co.uk/gp/product/B072JTMVYC

- 5-10 min job
- engine cover pull off
- pull off glopplug connector
- use air line or pipe to blow out any debri in plug hole
- remove/replace gloplug (make sure you compare them side by side for similarity)
- repeat steps in reverse
- clear DTC
- make a brew
Heres the new and old and 10mm socket
