Several years ago, Vitesco introduced itself as “restorers” of the injectors. Initially, under the labels put on by this “solid” enterprise (which reminded and still reminds of a completely shady business), inscriptions of 10+ old injectors were found. Later, these old injectors were replaced by a year/two years old items. From that moment on, the situation (in my view) became even more interesting. Why should somebody stick their own labels on (recently) professionally restored injectors? The internet community had a version – rebranding. For me, this explanation did not sound logical. Rebranding the most reliable of available OEM products, with a personal, much less known brand in the industry, using some crooked labels, and at the end selling it cheaper? What kind of “business” is that?
For a moment, it seemed the quality of the injectors sold by Vitesco (exactly sold, not restored) was better. Until… This time, something went wrong.
Customer: owner of N53. This time, the car was not maintained for years. Everything was bad with all injectors, NOx system, probes, VANOS, etc. But the owner was optimistic. Repaired the exhaust, including the NOx system. Repaired VANOS. Next step – replacement of the injectors.
The owner sent live and adaptation data after installing “new” injectors. Here is what became of it.
There are no improvements – the car shivers, check engine lights up on a regular basis, cylinders are switched off, etc.
As we see, DME is not able to create the initial adaptations in Homogeneous mode. Stratified charge was a bit more successful; some kind of initial adaptations were created.
Here, cylinders No.1 and No.2 are switched off. Error messages regarding switching off these cylinders are recorded on a regular basis. We can assume that the injector of the 3rd cylinder is harshly leaking.
Here we see:
a. 2nd injector is leaking;
b. 5th injector is leaking;
c. 4th injector has zero (very poor) atomization.
And here are the emails from the owner of the car:
As we see from the data, at least 3 out of 4 Vitesco injectors have serious problems. And now what? The note about the certified parts seller does not hold up to criticism. Vitesco is not, and never has been, a BMW/OEM supplier. Accordingly, no “certification” of the seller means anything; the customer has bought production of an alternative supplier. If the seller “made pressure”, say, we are certified, super-trusted sellers – excellent, now they have the option to show their reliability in problem-solving.
Second, I would like to discuss the second part of the email regarding the excellent experience with the service.
If we assume the service is a specialist in this area, why did their customer approach me with a request to help with diagnostics? Why did they not perform diagnostics by themselves?
Another topic – to evaluate the performance of these injectors, Stratified charge has to be restored. Only then will DME measure these injectors; only then will the data regarding atomization, dripping, and flow rate differences from ideal in all driving conditions be available. If we believe in “hundreds” of injectors, several tens (as a minimum) of cars would need restoration of the NOx system. The owners of these cars have two options:
a. install new OEM sensors, but then the NOx catalytic converters will have to be replaced too (they cost at least EUR 6000);
b. install NOXEM.
In this region, no service is standing out with the mass purchase of NOXEM. Really, the wealthiest customers of Europe could be based here? Customers who purchase the NOx catalytic converter for EUR 6000, but try to save on buying non-OEM injectors?
Of course, not!
And here is a logical conclusion. Either the service was lying about purchasing so many injectors, or they were replaced without the customer’s knowledge, and the Stratified charge was not restored. And then, instead, a logical question – how can you evaluate the quality of the injectors, if there are 0 everywhere in their adaptation data? How? The answer is simple – all these claims are of zero weight. These are a mixture of lies and total incompetence.
In this case, the customer must obviously try to get his money back and purchase OEM injectors.
