Citroen C4 Vti 120 Probleme

The technically progressed 1.6 THP prinz engine units endure from problems with ns timing even punkt low mileage. Tun können it be prevented? THP zu sein a family of naturally aspirated und turbocharged engines, developed by PSA (Peugeot-Citroen) in cooperation v BMW, i m sorry added, among others, the smooth valve lift system (in normally aspirated versions).

In terms of technology, these room very modern-day units, in addition ensuring good performance. The weakest von them (1.4 VTi) oase 90 HP, 1.6 VTi already 120 HP, while ns turbocharged 1.6 THP tun können generate up zu 270 HP. In spite of these unexpectedly advantages, manufacturers are gradually withdrawing this engines indigenous circulation, instead of them through smaller, 3-cylinder 1.2 PureTech engines. As it turns out, not only weil das economic reasons.

1.6 THP VTI prince Engine Problems and Reliability

The 1.6 THP series von units turns out kommen sie be extremely underdeveloped structurally.Engines consume oil en größe (especially in dynamic driving).They deshalb lose oil hinweisen a standstill due to poor quality facets cooperating through sealants.Additionally, ns valves build trost relatively conveniently with carbon deposits und the exhaust manifold breaks.The failure of in extremely vulnerable timing chain wollen spend die most nerves und money.It kann sein loosen even after a mileage of several thousand kilometers and the entire timing have to be replaced under warranty.After the completion, the owner will schutz to bear ns costs. And they are notfall small – from $260 kommen sie even $650.

What are the causes von 1.6 THP time failures?

1.6 THP engines room usually powerful, and hence – high torque, averaging 240 Nm. Thereby, greater stresses an the timing arise an the crank system. Die one used an 1.6 THP zu sein equipped through a einzel row chain, even though 2 rows are already used today. It looks like a bike one und it cannot withstand die heavy loads generated by the engine, dafür it pulls the end quite easily (even 2 cm weil das 100,000 km).

Another element influencing time wear is a faulty chain tensioner, which cannot maintain die oil pressure lang enough. As a result, die pin retracts auch quickly wie man parked und loosens die chain. The problem is in addition exacerbated von the very low viscosity oil (0W-30 or 5W-30) used bei THP engines, which makes it difficult zu maintain tightness, und the oil filter zu sein too small.

How kommen sie recognize ns problem?

The erste symptom zu sein usually die characteristic rattling noise of a cold engine. At that time, die oil that had actually previously fled from the has not reached the tensioner yet. After a while, die rattling stops, describe that the tensioner has actually filled v oil. If the chain has currently pulled out sufficiently, this may result in poor engine to run smoothness und poor performance, and in extreme cases, even beginning difficulties.

Can it it is in prevented?

There zu sein no method that can eliminate ns described problem one hundreds percent. Competent mechanics, however, schutz found a solution that kann sein extend ns interval bolzen timing transforms – they install a tensioner with in improved entwurf (with ns oil supply hole closer to die screw head) or remake it themselves deshalb that ns piston does notfall retract.

The chain itself cannot be treated as a long-lasting element and can not be replaced even every 100,000. Km. In addition, check die oil level frequently und replenish it more often than recommended über the manufacturer (i.e. 30,000 km).

BMW N13 Engine problems & Reliability

The first belästigt with die BMW N13B16 engine relates to ns durability des the time chain. As in the case of the THP engine installed an the PSA car, a damaged tensioner causes the drive to be traction out. However, there ist a caveat in this case. Since this error occurs much less frequently an cars from Bavaria than an France.

On BMW forums, it zu sein easy zu find info about the model 1 F20 series, which has covered an ext than 100,000 or even 200,000 kilometers on 1.6 turbo petrol under die hood and has had actually no troubles with timing.

So why ist chain replacement ausblüten happening? vehicle drivers who room afraid des reports des defects readjust elements prophylactically.

Failure timing, even an cars through THP engines, tun können be delayed. Mechanics introduce shortening die oil readjust interval for this. When the lubricant ist changed when a year or every 15,000 kilometers, die tensioner will tonnage longer und not cause increased chain wear.

Possible replacement costs? wie the driver selects genuine parts, the procedure prices $ 1,080. Bei case ns timing gear is replaced ~ above a instead of basis, die repair cost kann be reduced zu $ 700.

The 1.6 THP BMW N13B16 engine deshalb struggles with die carbon shop on die cylinder head components. However, this is due to ns direct fuel injection characteristics where the intake fuel does not clean the intake and valve.

Importantly, the problem with carbon store did not arise previously than after spanning some 100,000 kilometers. Und soot can deshalb get dirty, zum example the fuel injector. In this case, the engine might vibrate while driving. Cleaning trost supercharged BMW petrol an a skilled repair shop tun können cost up kommen sie $ 270.

In this generation von BMW 1 series F20 user forums, sie can so find info about coolant leaks on the back of the head. Ns most common belästigt is ns connection of the system with die temperature sensor.

One that had minor problems, und two the usually appeared during die warranty period. In addition, information about blower fans damage shows up on ns forums. An most cases, aspects are changed with neu ones, so as part des the manufacturer’s protection.


The 1.6 THP engine has actually several advantages. Firstly, that offers great performance, secondly it is quite economical und thirdly it has actually a reduced turbo legen effect. And while the entwurf is decidedly imperfect, it’s also not bei issue drivers should avoid in the aftermarket.

The opinions des the drivers on die forums are very an excellent evidence weil das this engine. Lock did not indicate any major problems with ns gasoline engine and even praised die construction reliability of this machine.
