E85 2.0 vs 3.0 // off the line

[Z4 COUPSTER]

What about running cost comparison?
I'm more than happy with my 2 litre although, if I wasn't skint I would probably have gone for a 3 litre.

Very little in it cost per mile as you have to work the 2.0i so hard. I'd say the 3.0i overall is far better in all ways including the issues mentioned. I'm not a hater but I think BMWs should have six pots, including the diesels.And over the years I've had loads of different variants. Main thing with the four pot is make sure services are kept up and things should be ok. Fingers crossed.

But does it matter often enough to make you want to change your car OP?

Then again you can get 3 litre ones in Montego Blue with Pearl Grey leather thankfully!

2.0l common issues:

Good luck and I hope you never have any of them. But fact are facts the exhaust manifolds crack! Seen one for myself. They can be fixed though.

• Cracked exhaust manifolds (expensive as has cat built in).

• Timing chain tensioner failures

• Plethora of emissions related problems that seem hard to resolve

• Valvetronic motors more prone to failure

Not common issues on mine, had the 2.0i since febuary last year, 10000 miles later not missed a beat
