BMW E46 Touring - fault codes ???

Hi guys,

Just joined recently and thought i would try my luck, as it says above ive brought myself a E46 320i touring (2.2 litre).

Keep getting engine light on after say 50 miles, codes below:

P1343, P 1347, P 1345, P1620 & P0174......

Once engine light appears, car runs sluggish, lumpy & idles slow

From what l can gather ignition coil 2/earth is faulty plus plugs could do with a change, map thermostat fault ?? or clean/replace fuel filter ???

This is my daily driver so it need to be right

Thanks in advance

Doubt your problem is with a coil.

You have a Lean code and misfires with fuel cut off.

Also looks like you have a thermostat codes as well.

Suggest your read the first 3 links below in my signature.

Suggest you read my "BMW 20 Questions" comments in this thread - http://forum.e46fanatics.com/showthread.php?t=1059972

Search YouTube for Scotty Smoke Test. Do what Scotty does or make a smoke tester from a related video.

Post back Freeze Frame and Fuel Trim info as well.

Most likely, due to a vacuum leak on that busted hose. Good luck.

One comment "Whack A Mole". You may have only one problem at the moment, but you have PLENTY more waiting.

Do not declare ultimate victory when you find just one bad hose.

Trust me!

BTW, nice car if you can get the steering wheel on the proper side. Shifting left handled is for the birds.

U above r not wrong, stripped down all breather pipes/valve......

full of gunk/oil sludge/sh%t in valve, more pipe perished and plugs look like they have been cooked under nasa shuttle

Hopefully once l replace all these part, l will be on the road to recovery....


Hopefully

Dont worry, will clean out throttle/ housing and so on.....

Cant be to careful

Cheers
