Golf 7 16 Tdi Bluemotion Probleme


The VW 1.4 TSI comes in two various versions: ns EA111 (2005 – present) und the EA211 (2012 – present). The EA111 has actually won plenty of awards, including multiple ‘International Engine of the Year’ awards. Through that said, numerous say this zu sein a good engine, however like many engines, they space a list of common problems. The EA211, being developed after ns EA111, doesn’t have as many shortcomings as the early EA111’s had.

The EA111 zu sein unique an the feeling that it has actually two various versions: one’s less powerful (with nur a TD02 turbocharger) und a more powerful twin-charged one (with an Eaton-Roots supercharger und a K03 turbocharger). The less powerful, one turbo, EA11 puts out 122-131 bhp & 148-160 lb-ft torque. The more powerful, supercharger and turbocharger, EA111 puts out 140-179 bhp & 162-184 lb-ft torque. Zum the size von the engine, you would be surprised by the acceleration.

The EA211 supersedes ns EA111 and surprisingly it is in entirely new engine. Unlike die EA111, this engine only has a turbocharger that hülle out 122-150 bhp & 147-184 lb-ft torque. Surprisingly, the EA211 ist lighter than die EA111 due zu new and improved internals. Something to note, ist both von these engines gain excellent mpg. Ns overall goal of the 1.4’s was kommen sie bring ns power von the 2.0’s, yet with far better fuel economy, which Volkswagen absolutely delivered.

The 5 Most common Volkswagen 1.4 TSI Engine Problems

Excessive Oil ConsumptionIgnition Coil FailureTiming Chain Tensioner FailureTurbo Wastegate StickingEngine Warming up SlowlyCarbon Buildup

1. Too much Oil Consumption

Excessive oil consumption ist a belästigung that ist most seen in the early on versions von the EA111 1.4’s, und not dafür much on ns EA211’s. If you notice the your vehicle’s oil zu sein consuming much more than normalerweise oil (1qt every 1,000 miles), climate this can be occurring. If sie feel this might be the case, that needs prompt attention as major engine damage kann sein occur if neglected. In the early on EA111’s, the pistons and piston rings weren’t die most reliable, which causes this issue. Part precautions the you tun können take are: gain a consumption prüfen done zu confirm there is nothing not correct with ns pistons, use ns correct oil listed in your VW manual, und use high-quality fuel.

Symptoms of Excessive Oil Consumption:Performance lossIncrease an oil depositsEngine warming hoch slowly in cold temperatureReduced fuel economyLower than normalerweise oil levels zum a set durationBlue smoke emitting from the exhaust

If her vehicle is noticing any von the symptoms provided above, take it seriously. This could cause serious engine damage to the pistons if neglected and would put much more stress on the engine itself. If you glauben your vehicle is consuming an excessive amount des oil, take it it to your local shop and have castle take down your oil levels climate go zurück 1,000 mile after und see if this zu sein happening.

2. Ignition Coil Failure

Unfortunately, ignition coil und spark plug failure are common an most turbocharged engines nowadays. Ns ignition coils und spark plugs pat a large part in combustion. Essentially, ns ignition coil takes ns voltage from ns battery und creates a spark to the spark plugs to ignite the vehicle’s fuel. If this aren’t work properly, your vehicle wollen experience misfires.

Ignition coils are claimed to tonnage up kommen sie 100,000 miles, while the spark plugs tonnage around 30,000 – 60,000 miles. A good rule von thumb zu sein when one spark plug or ignition coil goes out, we recommend replacing all of them, just so you won’t schutz to worry around worn parts combined with neu parts.

Symptoms von Ignition Coil Failure:Engine misfires (P0300, P0301, P0302, P0303, or P0304 error Code)Check Engine irradiate (CEL) illuminatingDecreased accelerationRough idleEngine not starting

If you’re experiencing the above symptoms, we advise using in OBD scanner to confirm it is in ignition coil failure. After confirming, this is a straightforward DIY that shouldn’t take much more than 2 hours. If sie decide kommen sie take it to a shop, you will be looking punkt a bill of about ~$200.

3. Time Chain Tensioner Failure

Tensioner failure is very common in Volkswagen’s together they were not built really durable out von the factory. Die tensioners in the 1.4’s space no exception. A timing chain tensioner ensures the tension des the time chain ist at the engine’s optimal tension to drive numerous important components des the engine. Time chains were implemented bei the early EA111’s, but ns EA211’s switched over kommen sie timing belts.

If ns tensioner happens zu fail, ns timing of the engine can be off which would cause serious engine damages to ns pistons. If you have an EA111, we extremely suggest gaining ahead von this repair, due to the fact that once sie replace it through a more reliable tensioner, sie shouldn’t schutz to replace it again.

Symptoms des Tensioner/Timing Chain Failure:Poor engine performanceMetal shavings bei oil/oil panEngine rattle when idleLoose time chainEngine shuddering

There are really two dinge you kann sein do if sie feel your tensioner has failed: replace nur the tensioner or replace the timing chain kit. We very advise changing the entire kit, dafür there aren’t neu products mixed with old products. This DIY ist not zum somebody that hasn’t excellent a lot of arbeiten to in engine, it ist very difficult. If sie plan on acquisition it to a shop, you’ll be looking at a rechnung ~$1,000 depending upon where you go.

4. Turbo Wastegate Sticking/Rattling

Turbo wastegate sticking/rattling is unfortunately notfall more common an the EA111’s, it’s actually equally common in the earlier versions and later versions. Die wastegate bei a turbo ist essentially a valve that regulates rise pressure. That controls the speed von the turbine und ensures that die turbine is not rotate too in der nähe des causing an increase pressure zu rise indefinitely.

There are two ways a wastegate kann sein be stuck: open or closed. If it ist stuck closed, your turbos would over boost, if stuck open, die boost möchte be really laggy. One of two people case ist not good on ns turbo’s and would cause a lot of anxiety on them. If this went unattended for a particular period von time, your turbos can blow, which will be a costly repair. However, if sie get ahead of it, this can be a straightforward repair of the wastegate or die actuator.

Symptoms of Turbo Wastegate Sticking:Dramatic decrease bei fuel efficiencyEngine flutterPoor engine performance (mainly acceleration)Oscillating boost pressureRattling noise from the turboP2563 or P00AF fault codes

After determining that your wastegate might be the issue, over there really ist one way to fix ns issue: replace the wastegate or replace die turbo. This is not bei easy DIY, deswegen make sure freundin know your means around the engine if freundin choose kommen sie do it on her own. If you are looking kommen sie take it to ns shop, you would it is in looking at around ~$400 zum the wastegate replacement or ~$2,500 zum turbo replacement.

5. Engine Warming up Slowly

This belästigt is together it states, ns engine takes a very lang time kommen sie warm up und occurs ~ above both die EA111’s und EA211’s. Wie we say, “takes a lang time”, we’re talking about 10 – fünfzehn minutes nur to offer context on how long. After ~ digging zum a little, it has actually been figured out that this problem persists because von the way die engine was built. Since ns 1.4’s space a smaller sized engine, this means there is smaller displacement which an the ende means less heat generation. Unfortunately, over there isn’t much one can do zu alleviate this problem it just comes with ns 1.4’s because von the engine’s size.

Something we suggest is starting your vehicle 10-15 minute before you have to leave, to give it ample time zu warm up. Something precious noting zu sein do not push on die engine if it is not at the optimal temperature as this might lead zu serious engine damage.

6. Carbon Buildup

Since the 1.4 TSI has a direct injection fuel system, carbon buildup wollen happen naturally. Fuel zu sein injected weist high pressure directly into the combustion chamber which results bei a slow buildup des carbon bei the engine’s valves and ports. When this happens, the vehicle wollen experience slow-moving engine performance, engine misfires, und clogged fuel injectors. As the engine gets closer zu 40,000 miles, chances are zu sein that there zu sein a bunch des carbon built hoch already. Again, this is natural und is hard to prevent 100%, but there are sachen to do zu limit die amount von buildup.

Symptoms of Carbon Buildup:Sluggish engine performanceEngine misfiresClogged fuel injectorsEngine knockingPoor fuel efficiencyHard engine startsWays kommen sie Prevent Buildup:Run your engine difficult once a month zum 20-30mins (4500RPMs)Use ns highest top quality fuel possibleEthanol fuel injector cleanerChange your oil regularlyManually clean ns valves every 20,000 milesGet ns valves walnut blasted every 45,000 miles

If you didn’t know this was a thing until now, or room looking for a provided VW/Audi that has actually 50,000 miles or more, us suggest beginning off through a walnut blasting service and using ns preventative procedures after. As crazy as it sounds, some enthusiasts claim kommen sie unlock up to 20hp shed due to die valves and ports gift clogged. ~ above top des that, in engine through clean valves und ports, boosted throttle response, far better idle, and in engine that will run like new.
