Update.
Six new ignition coils fitted. Quality isn't great though (they are Bosch ones, £35 each). Two of them the plastic clips that hold the wiring connector in place were starting to split, so they wouldn't lock. Luckily the old ones I removed were the same design and the plastic is sturdier, so I was able to swap the top clips off the old part.
And the new battery is installed. Not too hard a job just a bit awkward with all the wiring to move around.
Car is starting and running fine.
But I have found two more issues.
First is quite serious. This auxillary belt was only replaced in November at a local indy who I have used for many years and who normally do a good job. Along with new tensioner pulley. It is freying badly and chunks are missing from the belt.
Ive phoned them up just now and taking the car back in on Tuesday next week but Im very annoyed because now this is a risk to even drive it. Obviously a poor fitting job or poor quality parts not sure which.
Im tempted to do the job myself if I can get the parts, it doesn't seem difficult. But then that lets the garage off the hook for the initial poor work.
Second issue is that I have found a source of my oil consumption - the oil filler cap appears to be allowing some seepage. This was all wiped off a couple days ago and now there is seepage around the cap again, it can only be coming from the cap in that location. So now need to see how to replace this whole part.
