Servus, i.e. at the 320d from the father, has been hearing a tacker for many KMs, especially under load when accelerating. The Bosch service thinks this would clearly be a combustion noise and probably the fault are the injectors. A check of this costs approx. 300€. Now I bought two new (!) injectors at Ebay for a bargain price and would like to expand the old ones and then replace them according to the defects. Who has tips for the construction, installation and start of the engine for me? If the parts have not yet been removed, however, it is well known that: – the injectors may be fixed and go out very hard. – before the installation of a new injector of the seating area has to be cleaned well – new copper sealing rings have to be used. Unfortunately I do not know: – how to get out of the parts with fixed injectors – how I can clean the seats – with which torque the nuts for the injector clamps are removed again. – whether it is at the Neusta Achso ja: 320d, Bj 09/2003, 190,000km. First engine, first injectors, first loader. Who has useful and qualified information for me, please bring it here. Unusual comments like “This will go wrong” or similar gossip I don’t want to read here! Thanks! Jonny
