Hi all,
Im new here and have joined because my BMW 116i 2005 has a problem and could do with some help please.
All of a sudden yesterday the car started jumping and stuttering under higher revs, the issue got worse so I pulled over and called the AA. The following error code came up P0011 and P0014 on his meter but nothing showing on car dash.
Does anyone know what these errors could mean please?

Many Thanks

I couldn't say, there's a fair chance it would be a timing chain replacement, but might be necessary to replace the guides which would complicate it.

Have a read about N45 timing chain. Given that the engine suddenly started stuttering and shows both cams as over advanced, that's what my money's on.

timing chain kit including new guides is around £85 in euro car parts which is relatively cheap but the downside is the fitting of them is specialist as you need the proper timing setting equipment of which only a good mechanic will have and theres a fair bit of involved work around 4/5 hours at what ever they charge per hour.

Hi Thomson, not sure exactly but they didn't say they fitted anything different. The only different this time is car wont even start but before it started but was undriverable. So concerned chain may have snapped rather than just slipped waiting to hear from garage though.

From what I recall the original chain tensioner for these engines was duff and a revised unit is available; the old one allowed the timing chain to jump. It should be replaced with the new one, but it seems perhaps your garage hasn't done so.

Are they a BMW specialist?

thanks for your help mate. no original garage was not bmw specialist but its now with one. can i ask if chain has snapped would it mess up the valves/engine on a 2005 1 series or whats the score? no problems if your not sure. thank you

It's an interference engine so if the chain has snapped then it will have damaged the valves. If it was an Alfa 156 I'd expect about £2500 to put it right, so that ball park?

Could be it's just jumped though and it'll cost you whatever the original job did (plus the cost of tensioner / guides, whatever they replace).

Not great news either way I'm afraid, but fingers crossed.
