I'm updating the Mondeo Mk3 Buyers Guide, and am researching common problems. Are there any with the Mk3 V6? I can't think of any off the top of my head. What about things to look for if purchasing a V6?

Interested in finding out what all the crypto currency fuss is about and why so many people are making thousands of pounds?

Only things I can think of are the idle control valve which makes the 'moosing noise' and the idle tensioner which can rattle on idle... but both would be pretty apparent in any case.

Other than that, no common things to watch out for on these really, service history is key when buying one, main dealer is an advantage because then you've got a good chance they changed all 6 sparks. But then again, service history goes with out saying.

I could rebuild a Mondeo from the ground up with my eyes closed... that's thanks to owning a TDCI.

Hi I'm new to this sight after found it after trying to research problems with the 2.5 v6 zetec S Mondeo. I have just brought a 51 plate which drove very nice. After about one week it started cutting out when idle in traffic, then took about 6 attempts to start. After a few days the warning light came on so I got a mate to do the relevant checks. The result being error code P0320.

Today a garage replaced the crank sensor and I thought all was fine untill about 3 hours later the car cut out again when idle in traffic. This happened twice and the engine light came on but started on the first try. The light then went out on each occasion and was fine on the short journey home. Should I start worrying or getting more work done? My knowledge is pretty basic and usually rely on main dealers who hit the pocket tho!

Apologies if I have put this question in across someone else's. Any advice is appreciated.

Front wheel bearings and broken springs but i suppose all models suffer from these faults.

Hi I've ended up replacing leads, plugs and coil pack. Apparently very common problem. Aftermarket coil packs not meant to be much cop!

Not so sure it's a common issue on the v6 mate. Is on the 1.8 and 2.0 but not the v6. The coil packs and ht leads exceed 100k easily in my experience.

Is the weak head gasket not a common problem on the mk3`s like the mk1 & 2s?

Seems very common on the earlier engines, perhaps ford rectified the problem on mk3`s. Can anyone claryfy this?

Has the bottom end issues been sorted out? Better rod bolts and big end bearings?
