BMW E90/E91 316i

[Gast]

Hallo,

ik ben van plan een BMW 316i aan te kopen, van bouwjaar 2010 of 2011. Je leest soms van de kettingproblemen die een 318d kan hebben bij dit model, maar hoe zit het met de 316i ? Heeft deze ook een ketting of zijn er nog andere dingen waar ik bij moet opletten? En hoe loopt het onderhouds interval voor deze motor: om de hoeveel km en / of jaar heeft die courant onderhoud nodig?

Aan argumenten zoals: maar een 1600, maar een 4 cilinder of maar 122 pk heb ik geen boodschap. Graag enkele genuanceerde meningen over deze motor in combinatie met E90/E91 van die bouwjaren.

alvast bedankt.

Naften van de e9? reeksen stellen niet veel voor . Oliezuipers , onbetrouwbaar zelfs de 6 cilinders .
De enige interessante motoren zijn de 325d en 330d . Als het echt een naft moet zijn dan de prfacelift 325i en 330i van de éérste jaren die zijn nog ça va maar dan zit je wel met een wagen van rond de 10jaar waar van alles aan scheelt en koop je andermans rotzooi.

De N45 motoren gaan ook niet vrijuit. Daar zijn ook problemen geweest met de kettingspanners. Je moet maar is googelen. Persoonlijk vind ik de afwerking van de E90 niet goed. Veel goedkope plastieks rammels in het interieur. Maar de reden waarom mijn auto eruit ging na amper een jaar waren de rotslechte sportstoelen die me enorm veel rugpijn bezorgd hebben.

Even een quote aanhalen van iemand

De 116i N45(116i)/N46(118i) BENZINEMOTOREN hebben vroeger problemen gehad met de distributieketting die versprong.
Toen is er een nieuwe kettingspanner en en plaatje over de ketting gekomen aan de bovenzijde.
Deze motoren gingen "normaal" niet kompleet stuk.
Sommige hebben de pech gehad van wel,anderen konden hersteld worden

ik moet zwartpaard in deze wel gelijk geven

Beemer: moet dat niet de n43 zijn?

Hmmm... je doet me twijfelen. Even kijken

Ivm de N43 vind je mits googelen direct info

BMW N43B16 engine reliability, problems and repair[edit]

BMW N43B16 engines were produced to replace N42B18. However they showed up a bit late and were constructed on base of N43B20. This motor had cylinders with smaller diameter which was 82 mm in comparison with 2-liter N43B16 engine. It has shorter crankshaft which is 75.7 mm stroke. Displacement was decreased to 1.6 liters. If compared with its predecessor N42B18 new engine has pistons with higher compression ratio (12). At the same time direct injection system was installed while Valvetronic was removed. Siemens MSD 81.2 engine control unit is used in new motor. This engine was produced for BMW 16i models. N45B16 and N46B18 versions were also produced along with new engine for cheaper BMW modifications. 1.6-liter turbocharged 4-cylinder N13B16 engine turned out to be a new gen motor which replaced N43 in 2011. ===

BMW N43B16 disadvantages and problems[edit]

This engine is a smaller version of N43B20 and has the same problems. More detailed information on possible BMW N43 malfunctions is provided below:

1. Engine vibration. This problem is one of the most common in N43. You need to change injectors.

2. Misfire and rough idling on N43. The problem is mainly connected with ignition coils. You should check them and replace in case of necessity. 3. Vacuum pump starts leaking after 40,000-50,000 miles (60,000-80,000 km) of mileage. The only way to solve this problem is to change pump. Don’t forget to check conditions of your cooling system in order to prevent it from overheating.

4. N43 is rather demanding when it comes to motor oil and its quality. Operating temperature of the engine is rather high. It means that low quality oil may lead negative consequences for the engine. That is why you need to use motor oil that is recommended by BMW brand.

If you take care of N43B20 engine and proceed with all necessary changed and maintenance, it will serve you for a long time with minimum problems.

BMW Petrol N43 Engine failures - How To Prevent BMW Petrol Engine N43 Failures[edit]

What is causing the failures? This is not down to a design problem, or a mechanical problem with the engine as such but more down to "long-life" servicing which can lead to oil changes occurring every 20,000 miles. Combine this type of servicing with cars which have missed a service, gone overdue on a service, or even gone to a non-specialist garage where an incorrect oil grade is used during the service, and the result can be catastrophic. The problem is the engine oil. Engine oil is not only designed to lubricate moving parts it is also used to control temperatures inside the engine, for example by cooling pistons, but also to absorb carbon. Carbon is by-product of combustion and occurs both in petrol and diesel engines. As soon as you put new oil into an engine it is absorbing carbon from the moment you start the engine, when the oil is new this is not a problem the carbon is absorbed effectively and the car operates as normal. When the engine oil is "used" and has maybe done 10,000 miles + it becomes less effective, when the oil has done 15,000 + miles the oil can no longer absorb the carbon as it should and it starts to solidify or "sludge up" / "coke up" .This sludge then sticks to important engine components and can begin to block oil galleries and oil pumps. Once oil pumps, and galleries begin to block up, key components begin to get starved of oil, this can quickely lead to permanent damage and failure, often resulting in expensive repairs.

Hierbij een overzicht

The BMW N45 is a straight-4 DOHC piston engine which replaced the BMW N42 and was produced from 2004-2011.[1]

Compared with its N42 predecessor, the N45 does not have valvetronic variable valve lift.[2] As the N42, the N45 has variable valve timing (called VANOS by BMW).[1] The N45 was sold alongside the N43 (which has direct injection) and the N46 (which has valvetronic) straight-4 engines.

N45B16 1,596 cc 85 kW (116 PS; 114 hp) @ 6000 150 N·m (111 lb·ft) @ 4300 2004-2011
N45B20S 1,997 cc 130 kW (177 PS; 174 hp) @ 7000 210 N·m (155 lb·ft) @ 4250 7300 2006

N45B16

Applications:
•2004–2011 E87 116i E81 also has N45B16 in Turkey
•2006–2011 E90 316i E91

The BMW N43 is a straight-4 DOHC piston engine which replaced the N42 and was sold from 2007-2011.

Compared with its N42 predecessor, the N43 features direct injection. The N43 was sold alongside the N45 engine (which does not have valvetronic or direct injection)[1] and the N46 (which does not have direct injection) straight-4 engines.


Models N43B16 1,599 cc 90 kW (122 PS; 121 hp) @ 6000 160 N·m (118 lb·ft) @ 4250 2008-2011
N43B20 1,995 cc 125 kW (170 PS; 168 hp) @ 6700 210 N·m (155 lb·ft) @ 4250 2007-2011

Interessant. Zou dit de reden kunnen zijn dat mijn N13 motor in de soep is gedraaid? oliedruk was weggevallen, 2 dagen na de oliewissel (die om de 30.000km gebeurt), met grote schade tot gevolg.
