[Stu’s 2010 i30 1.6 crdi]

Hi folks. First post
Ive ended up with a friend’s car after he recently passed away. It’s a high mileage i30 and I’ve no idea what maintenance it’s had. It does have a service book that shows it’s been serviced every 10-20000 until about 4 years ago, no idea if it’s had anything since. So basically just want to know what maintenance all you i30 owners recommend to keep her going. Fingers crossed I get a few years out of it.
It’s a 2010 i30 1.6 crdi edition, manual. 147000 miles
VIN starts TMA
It judders a bit in first gear if you don’t give it a bit of gas.
Vibration at 18/1900-21/2200, in 3/4/5/6th, worse up hill
It doesn’t start great.
The mpg is quite poor as well, only getting about 45-50 to and from work, 30 mile journey, mostly uphill on the way downhill home.
It’s had the glow plugs and battery replaced. I’m going to give it a service.

Other than a petrol shampoo, what do you guys recommend 🤪
