Hi guys

Just got a ‘new’ car and it’s got a few issues.

The drivers heated seat only works on 5 or 6 and is roasting hot. Any idea why it’s not working 1-4?

The intermittent wipers don’t really work, adjusting the speed does nothing and when it’s raining it doesn’t go any faster, just the same every 30 second (or so) wipe. Any ideas?

Getting a fault code p2251 for the pre-cat oxygen sensor. Are these common faulty sensors? Or is it an actual problem? I reset the code and the engine management light stayed off for 150 miles then came back on.

The air-con isn’t getting very cold. Is that just a refill or is there a common fault I should know about?

It drinks fuel as you’d expect, has anyone remapped the 3.0l and got much better economy? What kind of results did you get?

Really appreciate the help/advice, thanks.
