DiscoStu Posted January 10, 2009 Share Posted January 10, 2009 Hi all, quick question. Are 300Tdi fuel injectors serviceable by the home mechanic? If so, any information on how to do so would be appreciated. Stu. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted January 11, 2009 Share Posted January 11, 2009 Not a DIY job I'm afraid - they have to be calibrated. I was told that the bosch type can't be repaired anyway. It's not expensive to get them checked at a diesel specialist. Les. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted January 11, 2009 Share Posted January 11, 2009 The Bosch 300Tdi injectors are serviceable by a good diesel place. They reshim the springs to get the opening pressures back to as new. 200 Kpa IIRC. It is also possible to have the tips renewed, but this is not much cheaper than buying new ones unfortunately.

DiscoStu Posted January 11, 2009 Author Share Posted January 11, 2009 Thanks lads. I may decide to go for a recon set, about £130 on ebay. Stu. Quote Link to comment Share on other sites More sharing options...
DaveSIIA Posted January 11, 2009 Share Posted January 11, 2009 At that price, I'd be looking round for new ones. Paddocks list them (ERR3339) as Bosch items for £37.50 + VAT each. I bought a set a few years back and they came in Bosch packaging, with correct Bosch markings, numbers, etc (checked against the original factory fit units they replaced). The improvement over the originals (258K miles!) was quite noticable - much better performance & economy. The injectors are two stage, so have two settings calibrate. Many diesel "specialists" can only set the first stage, so be aware of what you are buying. Quote Link to comment Share on other sites More sharing options...

freeagent Posted January 12, 2009 Share Posted January 12, 2009 You should find a set of new injectors on ebay for about £120... I did. I changed mine after my engine had done about 140k, they made a bit of a difference, but not huge. I've kept the old ones and will get them checked out at a decent diesel specialists at some point..
