Think I might need some injectors for my Audi A1 1.6 TDI 2011 can anyone help 

New or secondhand? 

Refurbished if anything 

Have you tried local diesel specialist who could check and calibrate these for you? 

No I haven’t mate is that cheaper than buying a full set of injectors? 

Please don’t send me PMs on this topic, and be kind enough to post what you put in an PM and answer my #2 post.

Thanks.

Overlapped post.

What symptoms do you have? I had injector issues with a 2012 Seat Leon 1.6tdi engine code CAYC. Initially I was quoted £500 each for new genuine injectors plus fitting and was warned off going for refurbished, non genuine or used as apparently they are individually coded to the engine ECU making anything other than specialist/dealer attention a no go. I almost scrapped the car until I found a guy in south Leeds who sorted the issues for a fraction of the money initially quoted. Have a look on the various blogs related to your engine code letters (CAYC or similar) as there is a lot of chatter about "failing" VAG injectors on the 1.6tdi and what to do. Mine just had a misfire at idle and wouldn't do more than 50mpg. What is your's doing? I'm no expert but I did a lot of reading on the subject before choosing what to do.

Ok so when I’m driving at say 35 mph in 5th gear I’ll put my foot down slightly and it’ll give a little judder then it’ll be fine when over 40 mph I’ve had a lot done to this car and the problem ain’t solved. What would you suggest? And I’ve just ordered a new MAF SENSOR 

You could waste an awful lot of money buying new parts at random. Better to get the fault diagnosed first before spending out.

I have nothing is coming up on the diagnostic at all 

I should make clear I'm not an expert and not in the motor repair trade so I can only offer my experiences and acquired knowledge. What made you think it needs a new MAF sensor? Have you had it plugged into a diagnostic kit to identify any relevant codes? The limit of my experience is with old mechanical diesel injection. What you have in the 1.6tdi is virtually all electronic and computer controlled. They work great for a long time but wear and dirt can cause any number of confusing symptoms according to the wide range of forums and blogs I read. Diesel injection is generally a dark art presided over by wizards. The injectors themselves have an electronic top half and a mechanical lower half. The top is basically a stack of piezo-electric wafers which expand when triggered by the ECU and push open the mechanical injector to release fuel - metered for every cylinder/revolution individually. If the piezo-electric wafer stack breaks down the injector won't fire and the engine will have a permanent misfire and be pretty much undriveable even with only one broken injector - the injector is toast. The misfire I had was only at idle and turned out to be a weakness in all four injectors in the lower/mechanical part. This part can be refurbished but the top part can not. The guy I went to charged £600 to remove, test (I was able to observe and very impressive it was too), diagnose and refurbish all 4 injectors which transformed the car to a smooth running car easily capable of the 60+ mpg it should have been. This was about a quarter of the cost quoted to replace all the injectors with genuine new ones. New injectors also need to "coded" to the ECU or else they will not run correctly and this can only be done with professional diagnostic kit. He needed the car overnight only. I note you are in Derbyshire so south Leeds is not close but also not impossibly far away if you want his details. Your symptoms sound repairable as it is still running tolerably. Hope this helps a bit.

Ok yh send me the details please if you don’t mind and I’ll get onto him straight away. Thank you for advice

Morning. The guy's name is Eddy and the business name is MK Diesel Injectors Specialist, 07455 215245. Address: Unit 1 Mafeking Mount, Beeston, Leeds LS11 7BX. You might see the Google review I left a year ago which recounts my experience. I had significant doubts when I saw the premises on street view and in person but the service was genuinely helpful and turned out to be great value. BTW - don't turn up in clean pale coloured clothes, the place is filthy and stinks of diesel as you might expect. Again, this was my experience and others may tell a different tale. He takes credit card payments BTW.
