po170
i have changed the first o2 sensor
camshaft sensor
icv
maf
oil
oil filter
fuel filter and plugs but it does it every mornin there is no air leaks and the emission pump is working fine help !!!!
When she is warm n for the rest of the day she is fine n great to drive but its really getting on my tats!
map cooling is ya thermostat if its getting up to temp in good time and staying steady ide tend to not worry about that one you can get that one just messing about with the coolant system..
p0135 is a duff lambda sensor heater circuit malfunction and may explain your cold start issues..
p0170 is engine running lean could be an intake vacuum leak
ide address the po135 first it may oe may not clear the po170..did you fit a cheap aftermarket sensor and was it pre cat or post cat??
changed sensor and checked most of wiring and seems ok but still have the fault codes po170 come up? i have a aftermarket air filter will this be te problem?
well mine does have 1.9 egr valve google it! started fine this morning after a new egr and shut off valve fitted , hopefully sorted if not ........ bmw for sale 318ci totally fine
BMW petrols "DO NOT" have EGR valves! your prolly talkin about the air pump valve which pumps air into the exhaust manifold, it does not recirculate exhaust gases as in an EGR...(exhaust gas recirculator)...
ok this does pritty much the same thing and it is wat the name bmw "mechanic" gave it
............. well didnt start this morning have not cot a clue any more ,has any body had this prob befor ? any help would be great !!!!
