If you are alert of unusual symptoms on your car, you are right to be concerned, because a car represents a big annual budget and unpredicted breakdowns don’t reduce the bill. So what if you think that you have a leaking injector on your Volkswagen ID.3? You most likely figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or abnormal black smoke. These three symptoms are the main signs of a leaking injector. As this troubles can end up in more severe engine trouble on your car, we thought we would compose this article content to help you ensure the failure of a leaking injector and handle it properly. To do this, we will first of all look into the circumstance of gasoline injectors and then at those of diesel injectors Volkswagen ID.3.

Leaking injector on my petrol Volkswagen ID.3

It is fundamental to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two sort of engines makes the injection distinct. The biggest difference lies in the pressure undergone by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.

Leaking injector on a petrol Volkswagen ID.3: The different leaks

It should be noted that injector leaks on a Volkswagen ID.3 equipped with a petrol engine are pretty infrequent. This is as a result of the much lower pressure in the petrol intake systems. Even so, there are two sort of leaks:

  • Leakage from the top of the injector:
    It is plausible that you have a leak from the top of the injector, this is the portion that is attached to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    Finally, you may encounter a leak coming from the lower portion of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen before.

Leaking injector on my diesel Volkswagen ID.3

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system creates very high pressure in the engine, as do the injectors. On these models, the pressure is more than 10 times higher than on the direct injection of car petrol engines, reaching 1800 to 2000 bars.

Leaking injector on diesel Volkswagen ID.3: The different leaks

In the circumstance of leaking diesel injectors on your Volkswagen ID.3, there are three different sort of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform after a while, in most cases the leak will be at the clamping point.
  • Injector return leakage:
    As its name reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Volkswagen ID.3 will be brought on by an O-ring or its plastic tip that leaks.
  • Injector base leak:
    This injection leak is one of the most annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should find an air noise and a compression loss.
  • If after checking you have oil leaking but it does not come from your injectors, we recommend you to read this article content on the existence of oil leaking on your Volkswagen ID.3.

Leaking injector on my Volkswagen ID.3, how to fix the leak

And at last, we’re going to look into how to fix a leaking injector on your car. Regularly a leak is connected, as we have seen sooner, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some safety measures:

  • Lower the pressure before any work is done…
  • Covering you to avoid the risk of fuel spillage
  • NEVER work on a running diesel engine injector.

Concerning the repair part of your leak, it will frequently be restricted to swapping the seals that have failed:

  • Locate the source of the leak
  • Take apart the injector in question
  • Replace the corresponding seal kit
  • Reassemble the set up and tighten with a torque wrench in accordance with the manufacturer’s standards.

In all cases, these interventions are not inevitably complicated, but if you have the smallest hesitation in the treatment of your injector that leaks on your Volkswagen ID.3, we recommend you to get closer to your auto mechanic to avoid any bad manipulation that could significantly harm the condition of your Volkswagen ID.3.
