Although we get very few injectors we sell back under warranty (around 0.25%) when we do we send them back to our suppliers for warranty repair / replacement.

Has anyone noticed that recently Bosch in particular are taking an age to process these claims, I currently have the first one this year in process and it's been in for 8 weeks and still no answer.

The injector in question has failed electrically (Bosch test kit) and always used to be a direct swap out, but now they are sending them back to Bosch Germany (so I am told) to strip and test them fully before giving a replacement / refund or rejection.

Due to this delay we are having to stand the cost of a new injector ourselves or have very upset customers, which we don't want.

We have been warned that due to a small amount of corrosion on the outside of the injector (it was unusually clean & had only been in 4 months) it is likely to be rejected, This has to be a get out Claus as if this were the norm hardly anything would be warranted if there were even the slightest sign of rust !!

Comments ?

I now have two further Bosch injectors in for warranty with Renault (different supplier, two different vehicles but from same batch, I buy in bulk) I will wait to see what result I get (been told they will be rejected already by parts dept, before they were even booked in) and what the report says, looks like to confirm legitimacy of first report
